GDB SIGSEGV opening a Fortran program compiled with ifort
This patch fixes a SIGSEGV when trying to open a Fortran program compiled with ifort (reproduced using version using version 16.0.1.150). The error can be reproduce with most, if not any program. For instance, a single file only containing "end", compiled with no additional flag, suffices. gdb/ChangeLog: PR gdb/19208 * dwarf2read.c (read_partial_die): Do not call set_objfile_main_name if the function has no name. |

gdb: Handle multiple base address in debug_ranges data.
It is possible to use multiple base addresses within a single address range series, within the .debug_ranges section. The following is a simplified example for 32-bit addresses: .section ".debug_ranges" .4byte 0xffffffff .4byte BASE_1 .4byte START_OFFSET_1 .4byte END_OFFSET_1 .4byte START_OFFSET_2 .4byte END_OFFSET_2 .4byte 0xffffffff .4byte BASE_2 .4byte START_OFFSET_3 .4byte END_OFFSET_3 .4byte 0 .4byte 0 In this example START/END 1 and 2 are relative to BASE_1, while START/END 3 are relative to BASE_2. Currently gdb does not correctly parse this DWARF, resulting in corrupted address range information. This commit fixes this issue, and adds a new test to cover this case. In order to support testing of this feature extensions were made to the testsuite dwarf assembler, additional functionality was added to the .debug_line generation function, and a new function for generating the .debug_ranges section was added. gdb/ChangeLog: * dwarf2read.c (dwarf2_ranges_read): Unify and fix base address reading code. gdb/testsuite/ChangeLog: * gdb.dwarf2/dw2-ranges-base.c: New file. * gdb.dwarf2/dw2-ranges-base.exp: New file. * lib/dwarf.exp (namespace eval Dwarf): Add new variables to support additional line table, and debug ranges generation. (Dwarf::ranges): New function, generate .debug_ranges. (Dwarf::lines): Support generating simple line table programs. (Dwarf::assemble): Initialise new namespace variables. |

gdb/dwarf2read: Minimal handling of non-constant struct sizes.
Using the gdb.ada/var_rec_arr.exp test, where the program declares an array of variant records... type Record_Type (I : Small_Type := 0) is record S : String (1 .. I); end record; type Array_Type is array (Integer range <>) of Record_Type; ... and then a variable A1 of type Array_Type, the following command ocassionally trigger an internal error trying to allocate more memory than we have left: (gdb) ptype a1(1) [...]/utils.c:1089: internal-error: virtual memory exhausted. A problem internal to GDB has been detected, [...] What happens is that recent versions of GNAT are able to generate DWARF expressions for type Record_Type, and therefore the record's DW_AT_byte_size is not a constant, which unfortunately breaks an assumption made by dwarf2read.c:read_structure_type when it does: attr = dwarf2_attr (die, DW_AT_byte_size, cu); if (attr) { TYPE_LENGTH (type) = DW_UNSND (attr); } As a result of this, when ada_evaluate_subexp tries to create a value_zero for a1(1) while processing the OP_FUNCALL operator as part of evaluating the subscripting operation in no-side-effect mode, we try to allocate a value with a bogus size, potentially triggering the out-of-memory internal error. This patch avoids this issue by setting the length to zero in this case. Until we decide to start supporting dynamic type lengths in GDB's type struct, and it's not clear yet that this is worth the effort (see added comment), that's probably the best we can do. gdb/ChangeLog: * dwarf2read.c (read_structure_type): Set the type's length to zero if it has a DW_AT_byte_size attribute which is not a constant. gdb/testsuite/ChangeLog: * testsuite/gdb.ada/var_rec_arr.exp: Add "ptype a1(1)" test. |

fort_dyn_array: add basic fortran dyn array support
Fortran provide types whose values may be dynamically allocated or associated with a variable under explicit program control. The purpose of this commit is: * to read allocated/associated DWARF tags and store them in the dynamic property list of main_type. * enable GDB to print the value of a dynamic array in Fortran in case the type is allocated or associated (pointer to dynamic array). Examples: (gdb) p vla_not_allocated $1 = <not allocated> (gdb) p vla_allocated $1 = (1, 2, 3) (gdb) p vla_ptr_not_associated $1 = <not associated> (gdb) p vla_ptr_associated $1 = (1, 2, 3) Add basic test coverage for most dynamic array use-cases in Fortran. The commit contains the following tests: * Ensure that values of Fortran dynamic arrays can be evaluated correctly in various ways and states. * Ensure that Fortran primitives can be evaluated correctly when used as a dynamic array. * Dynamic arrays passed to subroutines and handled in different ways inside the routine. * Ensure that the ptype of dynamic arrays in Fortran can be printed in GDB correctly. * Ensure that dynamic arrays in different states (allocated/associated) can be evaluated. * Dynamic arrays passed to functions and returned from functions. * History values of dynamic arrays can be accessed and printed again with the correct values. * Dynamic array evaluations using MI protocol. * Sizeof output of dynamic arrays in various states. The patch was tested using the test suite on Ubuntu 12.04 64bit. gdb/ChangeLog: * dwarf2read.c (set_die_type): Add read of DW_AT_allocated and DW_AT_associated. * f-typeprint.c: New include of typeprint.h (f_print_type): Add check for allocated/associated status of type. (f_type_print_varspec_suffix): Add check for allocated/associated status of type. * gdbtypes.c (create_array_type_with_stride): Add check for valid data location of type in case allocated or associated attributes are set. Length of an array should be only calculated if allocated or associated is resolved as true. (is_dynamic_type_internal): Add check for allocated/ associated. (resolve_dynamic_array): Evaluate allocated/associated properties. * gdbtypes.h (enum dynamic_prop_node_kind): <DYN_PROP_ALLOCATED> <DYN_PROP_ASSOCIATED>: New enums. (TYPE_ALLOCATED_PROP, TYPE_ASSOCIATED_PROP): New macros. (type_not_allocated): New function.

Add some more casts (1/2)
Note: I needed to split this patch in two, otherwise it's too big for the mailing list. This patch adds explicit casts to situations where a void pointer is assigned to a pointer to the "real" type. Building in C++ mode requires those assignments to use an explicit cast. This includes, for example: - callback arguments (cleanups, comparison functions, ...) - data attached to some object (objfile, program space, etc) in the form of a void pointer - "user data" passed to some function This patch comes from the commit "(mostly) auto-generated patch to insert casts needed for C++", taken from Pedro's C++ branch. Only files built on x86 with --enable-targets=all are modified, so the native files for other arches will need to be dealt with separately. I built-tested this with --enable-targets=all and reg-tested. To my surprise, a test case (selftest.exp) had to be adjusted. Here's the ChangeLog entry. Again, this was relatively quick to make despite the length, thanks to David Malcom's script, although I don't believe it's very useful information in that particular case... gdb/ChangeLog: * aarch64-tdep.c (aarch64_make_prologue_cache): Add cast(s).

Add casts to memory allocation related calls
Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

DWARF: handle non-local references in nested functions
GDB's current behavior when dealing with non-local references in the context of nested fuctions is approximative: - code using valops.c:value_of_variable read the first available stack frame that holds the corresponding variable (whereas there can be multiple candidates for this); - code directly relying on read_var_value will instead read non-local variables in frames where they are not even defined. This change adds the necessary context to symbol reads (to get the block they belong to) and to blocks (the static link property, if any) so that GDB can make the proper decisions when dealing with non-local varibale references. gdb/ChangeLog: * ada-lang.c (ada_read_var_value): Add a var_block argument and pass it to default_read_var_value. * block.c (block_static_link): New accessor. * block.h (block_static_link): Declare it. * buildsym.c (finish_block_internal): Add a static_link argument.

Fix language of compilation unit with unknown file extension
Here, in dwarfread.c:process_full_comp_unit: /* Set symtab language to language from DW_AT_language. If the compilation is from a C file generated by language preprocessors, do not set the language if it was already deduced by start_subfile. */ if (!(cu->language == language_c && COMPUNIT_FILETABS (cust)->language != language_c)) COMPUNIT_FILETABS (cust)->language = cu->language; in case start_subfile doesn't manage to deduce a language COMPUNIT_FILETABS(cust)->language ends up as language_unknown, not language_c.

dwarf2read.c: Check type of string valued attributes prior to decoding.
This change introduces a new function, dwarf2_string_attr(), which is a wrapper for dwarf2_attr(). dwarf2read.c has been updated to call dwarf2_string_attr in most instances where a string-valued attribute is decoded to produce a string value. In most cases, it simplifies the code; in some instances, the complexity of the code remains unchanged. I performed this change by looking for instances where the result of DW_STRING was used in an assignment. Many of these had a pattern which (roughly) looks something like this: struct attribute *attr = NULL; attr = dwarf2_attr (die, name, cu); if (attr != NULL && DW_STRING (attr)) { const char *str; ... str = DW_STRING (attr); ... /* Use str in some fashion. */ } Code of this form is transformed to look like this instead: const char *str; str = dwarf2_string_attr (die, name, cu) if (str != NULL) { ... /* Use str in some fashion. */ ... } In addition to invoking dwarf2_attr() and DW_STRING(), dwarf2_string_attr() checks to make sure that the attribute's `form' field matches one of DW_FORM_strp, DW_FORM_string, or DW_FORM_GNU_strp_alt. If it does not match one of these forms, it will return a NULL value in addition to calling complaint(). An earlier version of this patch did this type checking for one particular instance where a string attribute was being decoded. The situation that I was attempting to handle in that earlier patch is this: The Texas Instruments compiler uses the encoding for DW_AT_MIPS_linkage_name for other purposes. TI uses the encoding, 0x2007, for TI_AT_TI_end_line which, unlike DW_AT_MIPS_linkage_name, does not have a string-typed value. In this instance, GDB was attempting to use an integer value as a string pointer, with predictable results. (GDB would die with a segmentation fault.) I've added a test which reproduces the problem that I was orignally wanting to fix. It uses DW_AT_MIPS_linkage name with an associate value which is a string, and again, where the value is a small integer. My test case causes GDB to segfault in an unpatched GDB. There will be two PASSes in a patched GDB. Unpatched GDB: (gdb) ptype f ERROR: Process no longer exists UNRESOLVED: gdb.dwarf2/dw2-bad-mips-linkage-name.exp: ptype f ERROR: Couldn't send ptype g to GDB. UNRESOLVED: gdb.dwarf2/dw2-bad-mips-linkage-name.exp: ptype g Patched GDB: (gdb) ptype f type = bool () (gdb) PASS: gdb.dwarf2/dw2-bad-mips-linkage-name.exp: ptype f ptype g type = bool () (gdb) PASS: gdb.dwarf2/dw2-bad-mips-linkage-name.exp: ptype g I see no regressions on an x86_64 native target. gdb/ChangeLog: * dwarf2read.c (dwarf2_string_attr): New function.

[Ada] Add support for subprogram renamings
Consider the following declaration: function Foo (I : Integer) return Integer renames Pack.Bar; As Foo is not materialized as a routine whose name is derived from Foo, GDB currently cannot use it: (gdb) print foo(0) No definition of "foo" in current context. However, compilers can emit DW_TAG_imported_declaration in order to materialize the fact that Foo is actually another name for Pack.Bar.

Add casts for legitimate integer to enum conversions
This patch is mostly extracted from Pedro's C++ branch. It adds explicit casts from integer to enum types, where it is really the intention to do so. This could be because we are ... * iterating on enum values (we need to iterate on an equivalent integer) * converting from a value read from bytes (dwarf attribute, agent expression opcode) to the equivalent enum * reading the equivalent integer value from another language (Python/Guile) An exception to that is the casts in regcache.c. It seems to me like struct regcache's register_status field could be a pointer to an array of enum register_status. Doing so would waste a bit of memory (4 bytes used by the enum vs 1 byte used by the current signed char, for each register). If we switch to C++11 one day, we can define the underlying type of an enum type, so we could have the best of both worlds. gdb/ChangeLog: * arm-tdep.c (set_fp_model_sfunc): Add cast from integer to enum.

Problem printing record with array whose upper bound is record component

As it happens, the upper-bound resolution for this range type works fine. What breaks is when we try to resolve this range type's target type, which is: <2><830>: Abbrev Number: 16 (DW_TAG_subrange_type) <831> DW_AT_upper_bound : <0x7fb> <835> DW_AT_name : (indirect string, offset: 0xc7b): reprod__obj_t__T4s___XDLU_1__selected_flights_length <839> DW_AT_type : <0x766> <83d> DW_AT_artificial : 1 It is actually pretty much the same as the first subrange type, so you might ask why this is causing trouble, when the resolution of the previous DIE worked like a charm??? Well, for that, we need to backtrack a bit, and notice that, ahead of the DW_TAG_structure_type's DIE, there is the following DIE: <1><7e1>: Abbrev Number: 6 (DW_TAG_typedef) <7e2> DW_AT_name : (indirect string, offset: 0xbae): reprod__obj_t__T5s <7e6> DW_AT_decl_file : 2 <7e7> DW_AT_decl_line : 17 <7e8> DW_AT_type : <0x849> ... and that DIE references an array type... <2><849>: Abbrev Number: 14 (DW_TAG_array_type) <84a> DW_AT_name : (indirect string, offset: 0xbae): reprod__obj_t__T5s <84e> DW_AT_GNAT_descriptive_type: <0x864> <852> DW_AT_type : <0x748> <856> DW_AT_sibling : <0x864> ... whose subrange is... <3><85a>: Abbrev Number: 15 (DW_TAG_subrange_type) <85b> DW_AT_type : <0x830> <85f> DW_AT_upper_bound : <0x7fb> ... where the subrange's base type is the DW_TAG_subrange_type DIE that is causing problem. In summary, we process the typedef first, which causes us to process the second subrange BEFORE we process the struct DIE itself, and therefore the struct's discriminent (DW_TAG_member #1). As a result, while trying to handle the reference to that DW_TAG_member #1 as the upper bound of the second range type, we do... case DW_AT_data_member_location: { [...] baton->referenced_type = get_die_type (target_die->parent, target_cu); ... where target_die->parent (DW_TAG_member #1) hasn't been processed yet, and thus get_die_type returns NULL. This is what later causes us problems trying to find the right address to use as the base address for our field, which then triggers the error message we are seeing. This patch fixes the issue by calling read_type_die instead of get_die_type. If the DIE has already been processed, then this is the same as get_die_type. If not, the it'll get the parent die to be read, and then get its type. gdb/ChangeLog: * dwarf2read.c (attr_to_dynamic_prop) <DW_AT_data_member_location>: Use read_type_die isntead of get_die_type. Tested on x86_64-linux, no regression. No testcase, unfortunately, as the reproducer was given to us by a customer, and it's been otherwise surprisingly difficult to reproduce the same error outside of that reproducer. |

DWARF: cannot break on out-of-line function nested inside inlined function.
Consider the following code, which defines a function, Child2, which is itself nested inside Child1: procedure Foo_O224_021 is O1 : constant Object_Type := Get_Str ("Foo"); procedure Child1 is O2 : constant Object_Type := Get_Str ("Foo"); function Child2 (S : String) return Boolean is -- STOP begin for C of S loop Do_Nothing (C); if C = 'o' then return True; end if; end loop; return False; end Child2; R : Boolean; begin R := Child2 ("Foo"); R := Child2 ("Bar"); R := Child2 ("Foobar"); end Child1; begin Child1; end Foo_O224_021; On x86_64-linux, when compiled at -O2, GDB is unable to insert a breakpoint on Child2: % gnatmake -g -O2 foo_o224_021 % gdb foo_o224_021 (gdb) b child2 Function "child2" not defined. (gdb) b foo_o224_021.child1.child2 Function "foo_o224_021.child1.child2" not defined. The problem is caused by the fact that GDB did not create a symbol for Child2, and this, in turn, is caused by the fact that the compiler decided to inline Child1, but not Child2. The DWARF debugging info first provides an abstract instance tree for Child1... <3><1b7b>: Abbrev Number: 29 (DW_TAG_subprogram) <1b7c> DW_AT_name : (indirect string, offset: 0x23f8): foo_o224_021__child1 <1b82> DW_AT_inline : 1 (inlined) <1b83> DW_AT_sibling : <0x1c01> ... where that subprogram is given the DW_AT_inline attribute. Inside that function there is a lexical block which has no PC range (corresponding to the fact that this is the abstract tree): <4><1b87>: Abbrev Number: 30 (DW_TAG_lexical_block) ... inside which our subprogram Child2 is described: <5><1b92>: Abbrev Number: 32 (DW_TAG_subprogram) <1b93> DW_AT_name : (indirect string, offset: 0x2452): foo_o224_021__child1__child2 <1b99> DW_AT_type : <0x1ab1> <1b9d> DW_AT_low_pc : 0x402300 <1ba5> DW_AT_high_pc : 0x57 [...] Then, later on, we get the concrete instance tree, starting at: <3><1c5e>: Abbrev Number: 41 (DW_TAG_inlined_subroutine) <1c5f> DW_AT_abstract_origin: <0x1b7b> <1c63> DW_AT_entry_pc : 0x4025fd <1c6b> DW_AT_ranges : 0x150 ... which refers to Child1. One of that inlined subroutine children is the concrete instance of the empty lexical block we saw above (in the abstract instance tree), which gives the actual address range for this inlined instance: <5><1c7a>: Abbrev Number: 43 (DW_TAG_lexical_block) <1c7b> DW_AT_abstract_origin: <0x1b87> <1c7f> DW_AT_ranges : 0x180 This is the DIE which provides the context inside which we can record Child2. But unfortunately, GDB does not take the abstract origin into account when handling lexical blocks, causing it to miss the fact that this block contains some symbols described in the abstract instance tree. This is the first half of this patch: modifying GDB to follow DW_AT_abstract_origin attributes for lexical blocks. But this not enough to fix the issue, as we're still unable to break on Child2 with just that change. The second issue can be traced to the way inherit_abstract_dies determines the list of DIEs to inherit from. For that, it iterates over all the DIEs in the concrete instance tree, and finds the list of DIEs from the abstract instance tree that are not referenced from the concrete instance tree. As it happens, there is one type of DIE in the concrete instance tree which does reference Child2's DIE, but in fact does otherwise define a concrete instance of the reference DIE; that's (where <0x1b92> is Child2's DIE): <6><1d3c>: Abbrev Number: 35 (DW_TAG_GNU_call_site) <1d3d> DW_AT_low_pc : 0x4026a4 <1d45> DW_AT_abstract_origin: <0x1b92> So, the second part of the patch is to modify inherit_abstract_dies to ignore DW_TAG_GNU_call_site DIEs when iterating over the concrete instance tree. This patch also includes a testcase which can be used to reproduce the issue. Unfortunately, for it to actually pass, a smal patch in GCC is also necessary to make sure that GCC provides lexical blocks' DW_AT_abstract_origin attributes from the concrete tree back to the abstract tree. We hope to be able to submit and integrate that patch in the GCC tree soon. Meanwhile, a setup_xfail has been added. gdb/ChangeLog: 2014-05-05 Pierre-Marie de Rodat <derodat@adacore.com> * dwarf2read.c (inherit_abstract_dies): Skip DW_TAG_GNU_call_site dies while inheriting children of an abstract DIE into a scope.

Properly intern constants into psymtab
Variables with a DW_AT_const_value but without a DW_AT_location were not getting added to the partial symbol table. They are added to the full symbol table, however, when the compilation unit's psymtabs are expanded. Before: (gdb) p one No symbol "one" in current context. (gdb) mt flush-symbol-cache (gdb) mt expand one.c (gdb) p one $1 = 1 After: (gdb) p one $1 = 1 To the user it's pretty strange, as depending on whether tab completion has forced expansion of all CUs or not the lookup might succeed, or not if the failure was already added to the symbol cache. This commit simply makes sure to add constants to the partial symbol tables. gdb/testsuite/ChangeLog: PR symtab/18148 * gdb.dwarf2/dw2-intercu.S (one, two): Add variables that have a const_value but not a location. * gdb.dwarf2/dw2-intercu.exp: Add tests that constants without location defined in non-main CUs are visible. gdb/ChangeLog: PR symtab/18148 * dwarf2read.c (struct partial_die_info): Add has_const_value member.

PR gdb/18021 - defend against "static virtual" methods
This bug appears to be caused by bad debuginfo. The method causing the sefault in the reporter's test case is marked both static and virtual. This patch simply safegaurds against this case in dwarf2_add_member_fn, where the code assumes that there is a `this' pointer when a virtual method is seen (more specifically, when DW_AT_vtable_elem is seen). It previously dereferenced the first formal parameter (`this' pointer), which in this case doesn't exist. GDB consequently segfaulted dereferencing a NULL pointer. gdb/ChangeLog PR gdb/18021 * dwarf2read.c (dwarf2_add_member_fn): Issue a complaint if we find a static method with DW_AT_vtable_elem_location. gdb/testsuite/ChangeLog PR gdb/18021 * gdb.dwarf2/staticvirtual.exp: New test. |

[gdb/DWARF] Introduce linked list for dynamic attributes
This patch introduces a linked list for dynamic attributes of a type. This is a pre-work for the Fortran dynamic array support. The Fortran dynamic array support will add more dynamic attributes to a type. As only a few types will have such dynamic attributes set, a linked list is more efficient in terms of memory consumption than adding multiple attributes to main_type. gdb/ChangeLog: * gdbtypes.c (resolve_dynamic_type_internal): Adapt data_location usage to linked list. (resolve_dynamic_type_internal): Adapt data_location to linked list. (get_dyn_prop, add_dyn_prop, copy_dynamic_prop_list): New function. (copy_type_recursive, copy_type): Add copy of linked list. * gdbtypes.h (enum dynamic_prop_node_kind): New enum. (struct dynamic_prop_list): New struct. * dwarf2read.c (set_die_type): Set data_location data. |

Split TRY_CATCH into TRY + CATCH
This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

Fix struct, union, and enum nesting in C++
In C, an enum or structure defined inside other structure has global scope just like it had been defined outside the struct in the first place. However, in C++, such a nested structure is given a name that is nested inside the structure. This patch moves such affected structures/enums out to global scope, so that code using them works the same in C++ as it works today in C. gdb/ChangeLog: 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> * dwarf2-frame.c (enum cfa_how_kind, struct dwarf2_frame_state_reg_info): Move out of struct dwarf2_frame_state. * dwarf2read.c (struct tu_stats): Move out of struct dwarf2_per_objfile.
