elf/x86-64: Subtract __ImageBase for R_AMD64_IMAGEBASE When linking Windows x86-64 relocatable object files to generate x86-64 ELF executable, we need to subtract __ImageBase, aka __executable_start, for R_AMD64_IMAGEBASE relocation: 1. Add link_info to struct output_elf_obj_tdata to store linker info and _bfd_get_link_info() to retrieve it. 2. Add ldelf_set_output_arch to set up link_info. 3. Add pex64_link_add_symbols to create an indirect reference to __executable_start for __ImageBase to support R_AMD64_IMAGEBASE relocation when adding symbols from Windows x86-64 relocatable object files to generate x86-64 ELF executable. 4.

bfd, ld, libctf: skip zero-refcount strings in CTF string reporting This is a tricky one. BFD, on the linker's behalf, reports symbols to libctf via the ctf_new_symbol and ctf_new_dynsym callbacks, which ultimately call ctf_link_add_linker_symbol. But while this happens after strtab offsets are finalized, it happens before the .dynstr is actually laid out, so we can't iterate over it at this stage and it is not clear what the reported symbols are actually called. So a second callback, examine_strtab, is called after the .dynstr is finalized, which calls ctf_link_add_strtab and ultimately leads to ldelf_ctf_strtab_iter_cb being called back repeatedly until the offsets of every string in the .dynstr is passed to libctf. libctf can then use this to get symbol names out of the input (which usually stores symbol types in the form of a name -> type mapping at this stage) and extract the types of those symbols, feeding them back into their final form as a 1:1 association with the real symtab's STT_OBJ and STT_FUNC symbols (with a few skipped, see ctf_symtab_skippable). This representation is compact, but has one problem: if libctf somehow gets confused about the st_type of a symbol, it'll stick an entry into the function symtypetab when it should put it into the object symtypetab, or vice versa, and *every symbol from that one on* will have the wrong CTF type because it's actually looking up the type for a different symbol. And we have just such a bug. ctf_link_add_strtab was not taking the refcounts of strings into consideration, so even strings that had been eliminated from the strtab by virtue of being in objects eliminated via --as-needed etc were being reported. This is harmful because it can lead to multiple strings with the same apparent offset, and if the last duplicate to be reported relates to an eliminated symbol, we look up the wrong symbol from the input and gets its type wrong: if it's unlucky and the eliminated symbol is also of the wrong st_type, we will end up with a corrupted symtypetab. Thankfully the wrong-st_type case is already diagnosed by a this-can-never-happen paranoid warning: CTF warning: Symbol 61a added to CTF as a function but is of type 1 or the converse * CTF warning: Symbol a3 added to CTF as a data object but is of type 2 so at least we can tell when the corruption has spread to more than one symbol's type. Skipping zero-refcounted strings is easy: teach _bfd_elf_strtab_str to skip them, and ldelf_ctf_strtab_iter_cb to loop over skipped strings until it falls off the end or finds one that isn't skipped. bfd/ChangeLog 2021-03-02 Nick Alcock <nick.alcock@oracle.com> * elf-strtab.c (_bfd_elf_strtab_str): Skip strings with zero refcount. ld/ChangeLog 2021-03-02 Nick Alcock <nick.alcock@oracle.com> * ldelfgen.c (ldelf_ctf_strtab_iter_cb): Skip zero-refcount strings. libctf/ChangeLog 2021-03-02 Nick Alcock <nick.alcock@oracle.com> * ctf-create.c (symtypetab_density): Report the symbol name as well as index in the name != object error; note the likely consequences. * ctf-link.c (ctf_link_shuffle_syms): Report the symbol index as well as name.

ld testsuite: change unresolved to unsupported/fail "unresolved" as a test result means runtest returns an error, which can be confusing when there is no apparent error unless you look in .log files. In particular many tests are skipped without reporting an error if no target C compiler is found, but if a target C compiler is found but won't compile a testcase for some reason we used to mark the test as unresolved. Which is no more worthy of an error than when lacking a C compiler entirely. * testsuite/ld-cdtest/cdtest.exp, * testsuite/ld-checks/checks.exp, * testsuite/ld-elf/binutils.exp, * testsuite/ld-elf/compress.exp, * testsuite/ld-elf/dwarf.exp, * testsuite/ld-elf/exclude.exp, * testsuite/ld-elf/frame.exp, * testsuite/ld-elf/indirect.exp, * testsuite/ld-elf/linux-x86.exp, * testsuite/ld-elf/sec-to-seg.exp, * testsuite/ld-elf/tls_common.exp, * testsuite/ld-elfcomm/elfcomm.exp, * testsuite/ld-elfvers/vers.exp, * testsuite/ld-elfvsb/elfvsb.exp, * testsuite/ld-elfweak/elfweak.exp, * testsuite/ld-ifunc/binutils.exp, * testsuite/ld-mips-elf/mips-elf-flags.exp, * testsuite/ld-misc/defsym.exp, * testsuite/ld-mn10300/mn10300.exp, * testsuite/ld-plugin/lto.exp, * testsuite/ld-plugin/plugin.exp, * testsuite/ld-scripts/align.exp, * testsuite/ld-scripts/assert.exp, * testsuite/ld-scripts/crossref.exp, * testsuite/ld-scripts/defined.exp, * testsuite/ld-scripts/extern.exp, * testsuite/ld-scripts/log2.exp, * testsuite/ld-scripts/map-address.exp, * testsuite/ld-scripts/phdrs.exp, * testsuite/ld-scripts/phdrs2.exp, * testsuite/ld-scripts/script.exp, * testsuite/ld-scripts/section-flags.exp, * testsuite/ld-scripts/sizeof.exp, * testsuite/ld-scripts/weak.exp, * testsuite/ld-selective/selective.exp, * testsuite/ld-sh/sh.exp, * testsuite/ld-shared/shared.exp, * testsuite/ld-srec/srec.exp, * testsuite/ld-tic6x/tic6x.exp, * testsuite/ld-undefined/undefined.exp, * testsuite/ld-undefined/weak-undef.exp, * testsuite/lib/ld-lib.exp: Don't use unresolved except after perror.

libctf, ld: fix symtypetab and var section population under ld -r The variable section in a CTF dict is meant to contain the types of variables that do not appear in the symbol table (mostly file-scope static declarations). We implement this by having the compiler emit all potential data symbols into both sections, then delete those symbols from the variable section that correspond to data symbols the linker has reported. Unfortunately, the check for this in ctf_serialize is wrong: rather than checking the set of linker-reported symbols, we check the set of names in the data object symtypetab section: if the linker has reported no symbols at all (usually if ld -r has been run, or if a non-linker program that does not use symbol tables is calling ctf_link) this will include every single symbol, emptying the variable section completely. Worse, when ld -r is in use, we want to force writeout of every symtypetab entry on the inputs, in an indexed section, whether or not the linker has reported them, since this isn't a final link yet and the symbol table is not finalized (and may grow more symbols than the linker has yet reported). But the check for this is flawed too: we were relying on ctf_link_shuffle_syms not having been called if no symbols exist, but that function is *always* called by ld even when ld -r is in use: ctf_link_add_linker_symbol is the one that's not called when there are no symbols. We clearly need to rethink this. Using the emptiness of the set of reported symbols as a test for ld -r is just ugly: the linker already knows if ld -r is underway and can just tell us. So add a new linker flag CTF_LINK_NO_FILTER_REPORTED_SYMS that is set to stop the linker filtering the symbols in the symtypetab sections using the set that the linker has reported: use the presence or absence of this flag to determine whether to emit unindexed symtabs: we only remove entries from the variable section when filtering symbols, and we only remove them if they are in the reported symbol set, fixing the case where no symbols are reported by the linker at all. (The negative sense of the new CTF_LINK flag is intentional: the common case, both for ld and for simple tools that want to do a ctf_link with no ELF symbol table in sight, is probably to filter out symbols that no linker has reported: i.e., for the simple tools, all of them.) There's another wrinkle, though. It is quite possible for a non-linker to add symbols to a dict via ctf_add_*_sym and then write it out via the ctf_write APIs: perhaps it's preparing a dict for a later linker invocation. Right now this would not lead to anything terribly meaningful happening: ctf_serialize just assumes it was called via ctf_link if symbols are present. So add an (internal-to-libctf) flag that indicates that a writeout is happening via ctf_link_write, and set it there (propagating it to child dicts as needed). ctf_serialize can then spot when it is not being called by a linker, and arrange to always write out an indexed, sorted symtypetab for fastest possible future symbol lookup by name in that case. (The writeouts done by ld -r are unsorted, because the only thing likely to use those symtabs is the linker, which doesn't benefit from symtypetab sorting.) Tests added for all three linking cases (ld -r, ld -shared, ld), with a bit of testsuite framework enhancement to stop it unconditionally linking the CTF to be checked by the lookup program with -shared, so tests can now examine CTF linked with -r or indeed with no flags at all, though the output filename is still foo.so even in this case. Another test added for the non-linker case that endeavours to determine whether the symtypetab is sorted by examining the order of entries returned from ctf_symbol_next: nobody outside libctf should rely on this ordering, but this test is not outside libctf :) include/ChangeLog 2021-01-26 Nick Alcock <nick.alcock@oracle.com> * ctf-api.h (CTF_LINK_NO_FILTER_REPORTED_SYMS): New. ld/ChangeLog 2021-01-26 Nick Alcock <nick.alcock@oracle.com> * ldlang.c (lang_merge_ctf): Set CTF_LINK_NO_FILTER_REPORTED_SYMS when appropriate. libctf/ChangeLog 2021-01-27 Nick Alcock <nick.alcock@oracle.com> * ctf-impl.c (_libctf_nonnull_): Add parameters.

ld script expression parsing Parsing symbol or file/section names in ld linker scripts is a little complicated. Inside SECTIONS, a name might be the start of an expression or an output section. Is ".foo=x-y" a fancy section name or is it the expression ".foo = x - y"? It isn't possible for a single lookahead parser to decide, so the answer in this case is that it's a section name. This is the reason why everyone writes linker script assignment expressions with lots of white-space. However, there are many places where the parser knows for sure that an expression is expected. Those could be written without whitespace given the first change to ldlex.l below. Unfortunately, that runs into a lookahead problem. Optional expressions at the end of an output section statement require the parser to look ahead one token in expression context. For this example from standard scripts .interp : { *(.interp) } .note.gnu.build-id : { *(.note.gnu.build-id) } at the end of the .interp closing brace, the parser is looking for a possible memspec, phdr, fill or even an optional comma. The next token is a NAME, but in expression context that NAME now doesn't include '-' as a valid char. So the lookahead NAME is ".note.gnu.build" with an unexpected "-id" syntax error before the colon. The rest of the patch involving ldlex_backup arranges to discard that NAME token so that it will be rescanned in the proper script context. * ldgram.y (section): Call ldlex_backup. Remove empty action. * ldlex.h (ldlex_backup): Declare. * ldlex.l (<EXPRESSION>NAME): Don't use NOCFILENAMECHAR set of chars, use SYMBOLNAMECHAR. (ldlex_backup): New function.

ELF: Don't generate unused section symbols For ELF targets, section symbols are required only for relocations. With -ffunction-sections -fdata-sections, there can be many unused section symbols. Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are With unused section symbols : 39411698 bytes Without unused section symbols: 39227002 bytes The unused section symbols in libstdc++.a occupy more than 180 KB. Add BSF_SECTION_SYM_USED to indicate if a section symbol should be included in the symbol table. The BSF_SECTION_SYM_USED should be set if the section symbol is used for relocation or the section symbol is always included in the symbol table. Add keep_unused_section_symbols to bfd_target to indicate if unused section symbols should be kept. If TARGET_KEEP_UNUSED_SECTION_SYMBOLS is defined as FALSE, unused ection symbols will be removed. Tested on Linux/x86. Other ELF backends need to: 1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE. 2. Mark used section symbols in assembler backend. 3. Remove unused section symbols from expected assembler and linker outputs. bfd/ PR 27109 * aix386-core.c (core_aix386_vec): Initialize keep_unused_section_symbol to TARGET_KEEP_UNUSED_SECTION_SYMBOLS. * aout-target.h (MY (vec)): Likewise. * binary.c (binary_vec): Likewise. * cisco-core.c (core_cisco_be_vec): Likewise.

Therefore, we can not use the original bfd_get/bfd_put to get/put the code for big endian targets.

libctf, ld: dump enums: generally improve dump formatting This commit adds dumping of enumerands in this general form: 0x3: (kind 8) enum eleven_els (size 0x4) (aligned at 0x4) ELEVEN_ONE: 10 ELEVEN_TWO: 11 ELEVEN_THREE: -256 ELEVEN_FOUR: -255 ELEVEN_FIVE: -254 ... ELEVEN_SEVEN: -252 ELEVEN_EIGHT: -251 ELEVEN_NINE: -250 ELEVEN_TEN: -249 ELEVEN_ELEVEN: -248 The first and last enumerands in the enumerated type are printed so that you can tell if they've been cut off at one end or the other. (For now, there is no way to control how many enumerands are printed.) The dump output in general is improved, from this sort of thing a few days ago: 4c: char [0x0:0x8] (size 0x1) [0x0] (ID 0x4c) (kind 1) char:8 (aligned at 0x1, format 0x3, offset:bits 0x0:0x8) 4d: char * (size 0x8) -> 4c: char [0x0:0x8] (size 0x1) [0x0] (ID 0x4d) (kind 3) char * (aligned at 0x8) [...] 5a: struct _IO_FILE (size 0xd8) [0x0] (ID 0x5a) (kind 6) struct _IO_FILE (aligned at 0x4) [0x0] (ID 0x3) (kind 1) int _flags:32 (aligned at 0x4, format 0x1, offset:bits 0x0:0x20) [0x40] (ID 0x4d) (kind 3) char * _IO_read_ptr (aligned at 0x8) [0x80] (ID 0x4d) (kind 3) char * _IO_read_end (aligned at 0x8) [0xc0] (ID 0x4d) (kind 3) char * _IO_read_base (aligned at 0x8) 5b: __FILE (size 0xd8) -> 5a: struct _IO_FILE (size 0xd8) [0x0] (ID 0x5b) (kind 10) __FILE (aligned at 0x4) [0x0] (ID 0x3) (kind 1) int _flags:32 (aligned at 0x4, format 0x1, offset:bits 0x0:0x20) [0x40] (ID 0x4d) (kind 3) char * _IO_read_ptr (aligned at 0x8) [0x80] (ID 0x4d) (kind 3) char * _IO_read_end (aligned at 0x8) [0xc0] (ID 0x4d) (kind 3) char * _IO_read_base (aligned at 0x8) [...] 406: struct coff_link_hash_entry (size 0x60) [0x0] (ID 0x406) (kind 6) struct coff_link_hash_entry (aligned at 0x8) [0x0] (ID 0x2b3) (kind 6) struct bfd_link_hash_entry root (aligned at 0x8) [0x0] (ID 0x1d6) (kind 6) struct bfd_hash_entry root (aligned at 0x8) [0x0] (ID 0x1d7) (kind 3) struct bfd_hash_entry * next (aligned at 0x8) [0x40] (ID 0x61) (kind 3) const char * string (aligned at 0x8) [0x80] (ID 0x1) (kind 1) long unsigned int hash:64 (aligned at 0x8, format 0x0, offset:bits 0x0:0x40) [0xc0] (ID 0x397) (kind 8) enum bfd_link_hash_type type:8 (aligned at 0x1, format 0x0, offset:bits 0x0:0x8) [0xc8] (ID 0x1c7) (kind 1) unsigned int non_ir_ref_regular:1 (aligned at 0x1, format 0x0, offset:bits 0x8:0x1) [0xc9] (ID 0x1c8) (kind 1) unsigned int non_ir_ref_dynamic:1 (aligned at 0x1, format 0x0, offset:bits 0x9:0x1) [0xca] (ID 0x1c9) (kind 1) unsigned int linker_def:1 (aligned at 0x1, format 0x0, offset:bits 0xa:0x1) [0xcb] (ID 0x1ca) (kind 1) unsigned int ldscript_def:1 (aligned at 0x1, format 0x0, offset:bits 0xb:0x1) [0xcc] (ID 0x1cb) (kind 1) unsigned int rel_from_abs:1 (aligned at 0x1, format 0x0, offset:bits 0xc:0x1) ... to this: 0x4c: (kind 1) char (format 0x3) (size 0x1) (aligned at 0x1) 0x4d: (kind 3) char * (size 0x8) (aligned at 0x8) -> 0x4c: (kind 1) char (format 0x3) (size 0x1) (aligned at 0x1) 0x5a: (kind 6) struct _IO_FILE (size 0xd8) (aligned at 0x4) [0x0] _flags: ID 0x3: (kind 1) int (format 0x1) (size 0x4) (aligned at 0x4) [0x40] _IO_read_ptr: ID 0x4d: (kind 3) char * (size 0x8) (aligned at 0x8) [0x80] _IO_read_end: ID 0x4d: (kind 3) char * (size 0x8) (aligned at 0x8) [0xc0] _IO_read_base: ID 0x4d: (kind 3) char * (size 0x8) (aligned at 0x8) [0x100] _IO_write_base: ID 0x4d: (kind 3) char * (size 0x8) (aligned at 0x8) 0x5b: (kind 10) __FILE (size 0xd8) (aligned at 0x4) -> 0x5a: (kind 6) struct _IO_FILE (size 0xd8) (aligned at 0x4) [...] 0x406: (kind 6) struct coff_link_hash_entry (size 0x60) (aligned at 0x8) [0x0] root: ID 0x2b3: (kind 6) struct bfd_link_hash_entry (size 0x38) (aligned at 0x8) [0x0] root: ID 0x1d6: (kind 6) struct bfd_hash_entry (size 0x18) (aligned at 0x8) [0x0] next: ID 0x1d7: (kind 3) struct bfd_hash_entry * (size 0x8) (aligned at 0x8) [0x40] string: ID 0x61: (kind 3) const char * (size 0x8) (aligned at 0x8) [0x80] hash: ID 0x1: (kind 1) long unsigned int (format 0x0) (size 0x8) (aligned at 0x8) [0xc0] type: ID 0x397: (kind 8) enum bfd_link_hash_type (format 0x7f2e) (size 0x1) (aligned at 0x1) [0xc8] non_ir_ref_regular: ID 0x1c7: (kind 1) unsigned int:1 [slice 0x8:0x1] (format 0x0) (size 0x1) (aligned at 0x1) [0xc9] non_ir_ref_dynamic: ID 0x1c8: (kind 1) unsigned int:1 [slice 0x9:0x1] (format 0x0) (size 0x1) (aligned at 0x1) [0xca] linker_def: ID 0x1c9: (kind 1) unsigned int:1 [slice 0xa:0x1] (format 0x0) (size 0x1) (aligned at 0x1) [0xcb] ldscript_def: ID 0x1ca: (kind 1) unsigned int:1 [slice 0xb:0x1] (format 0x0) (size 0x1) (aligned at 0x1) [0xcc] rel_from_abs: ID 0x1cb: (kind 1) unsigned int:1 [slice 0xc:0x1] (format 0x0) (size 0x1) (aligned at 0x1) [...] In particular, indented subsections are only present for actual structs and unions, not forwards to them, and the structure itself doesn't add a spurious level of indentation; structure field names are easier to spot (at the cost of not making them look so much like C field declarations any more, but they weren't always shown in valid decl syntax even before this change) the size, type kind, and alignment are shown for all types for which they are meaningful; bitfield info is only shown for actual bitfields within structures and not ordinary integral fields; and type IDs are never omitted. Type printing is in general much more consistent and there is much less duplicated code in the type dumper. There is one user-visible effect outside the dumper: ctf_type_(a)name was erroneously emitting a trailing space on the name of slice types, even though a slice of an int and an int with the corresponding encoding represent the same type and should have the same print form.

libctf, ld: prohibit getting the size or alignment of forwards C allows you to do only a very few things with entities of incomplete type (as opposed to pointers to them): make pointers to them and give them cv-quals, roughly. In particular you can't sizeof them and you can't get their alignment. We cannot impose all the requirements the standard imposes on CTF users, because the deduplicator can transform any structure type into a forward for the purposes of breaking cycles: so CTF type graphs can easily contain things like arrays of forward type (if you want to figure out their size or alignment, you need to chase down the types this forward might be a forward to in child TU dicts: we will soon add API functions to make doing this much easier). Nonetheless, it is still meaningless to ask for the size or alignment of forwards: but libctf didn't prohibit this and returned nonsense from internal implementation details when you asked (it returned the kind of the pointed-to type as both the size and alignment, because forwards reuse ctt_type as a type kind, and ctt_type and ctt_size overlap). So introduce a new error, ECTF_INCOMPLETE, which is returned when you try to get the size or alignment of forwards: we also return it when you try to do things that require libctf itself to get the size or alignment of a forward, notably using a forward as an array index type (which C should never do in any case) or adding forwards to structures without specifying their offset explicitly. The dumper will not emit size or alignment info for forwards any more. (This should not be an API break since ctf_type_size and ctf_type_align could both return errors before now: any code that isn't expecting error returns is already potentially broken.) include/ChangeLog 2021-01-05 Nick Alcock <nick.alcock@oracle.com> * ctf-api.h (ECTF_INCOMPLETE): New.

libctf, ld: more dumper improvements Dump more details about the types found in data object and function info sections (the type ID and recursive info on the type itself, but not on its members). Before now, this was being dumped for entries in the variable section, but not for the closely-related function info and data object sections, which is inconsistent and makes finding the corresponding types in the type section unnecessarily hard. (This also gets rid of code in which bugs have already been found in favour of the same code everything else in the dumper uses to dump types.) While we're doing that, change the recursive type dumper in question to recursively dump info on arrays' element type, just as we do for all types that reference other types. (Arrays are not a kind of reference type in libctf, but perhaps we should change that in future and make ctf_type_reference return the element type.) ld/ChangeLog 2021-01-05 Nick Alcock <nick.alcock@oracle.com> * testsuite/ld-ctf/array.d: Adjust for dumper changes. * testsuite/ld-ctf/data-func-conflicted.d: Likewise. * testsuite/ld-ctf/diag-cttname-null.d: Likewise. * testsuite/ld-ctf/diag-cuname.d: Likewise. * testsuite/ld-ctf/diag-parlabel.d: Likewise. * testsuite/ld-ctf/function.d: Likewise. * testsuite/ld-ctf/slice.d: Likewise. libctf/ChangeLog 2021-01-05 Nick Alcock <nick.alcock@oracle.com> * ctf-dump.c (ctf_dump_objts): Dump by calling ctf_dump_format_type.

libctf, ld: CTF dumper changes for consistency In most places in CTF dumper output, we emit 0x... for hex strings, but in three places (top-level type IDs, string table offsets, and the file magic number) we don't emit the 0x. This is very confusing if by chance there are no hex digits in the output. Add 0x consistently to everything, and adjust tests accordingly. While we're at it, improve the indentation of the output so that subsequent lines in aggregate output are indented by at least as many columns as the colon in the type output.
