Address issues triggered by the MIPS ISA bit handling change, usually in tests that make artificial DWARF-2 records: * gdb.cp/expand-psymtabs-cxx.exp -- this test is debugging an object file and assuming addresses will be 0; with the ISA bit set code addresses are 1 instead: (gdb) PASS: gdb.cp/expand-psymtabs-cxx.exp: set language c++ p 'method(long)' $1 = {void (long)} 0x1 <method(long)> (gdb) FAIL: gdb.cp/expand-psymtabs-cxx.exp: before expand p method $2 = {void (long)} 0x1 <method(long)> (gdb) FAIL: gdb.cp/expand-psymtabs-cxx.exp: force expand p 'method(long)' $3 = {void (long)} 0x1 <method(long)> (gdb) FAIL: gdb.cp/expand-psymtabs-cxx.exp: after expand Fix by matching any hex number, there's no value AFAICT for the test in matching 0 exactly, and I suppose the method's offset within section can be non-zero for some other reasons on other targets too. * gdb.cp/nsalias.exp -- this assumes instructions can be aligned arbitrarily and places code labels at odd addreses, setting the ISA bit and wreaking havoc: (gdb) PASS: gdb.cp/nsalias.exp: print outer::inner::innermost::x list outer::inner::innermost::foo Function "outer::inner::innermost::foo" not defined. (gdb) FAIL: gdb.cp/nsalias.exp: list outer::inner::innermost::foo break *outer::inner::innermost::foo No symbol "foo" in namespace "outer::inner::innermost". (gdb) FAIL: gdb.cp/nsalias.exp: setting breakpoint at *outer::inner::innermost::foo delete $bpnum No breakpoint number 6. (gdb) FAIL: gdb.cp/nsalias.exp: (outer::inner::innermost): delete $bpnum -- etc., etc... Fix by aligning labels to 4; required by many processors. * gdb.dwarf2/dw2-canonicalize-type.exp, gdb.dwarf2/dw2-empty-pc-range.exp, gdb.dwarf2/pr11465.exp -- these assume an instruction and consequently a function can take as little as 1 byte, which makes it impossible to look up a code symbol by an address with the ISA bit set as the address is already beyond the end of the function: (gdb) ptype f No symbol "f" in current context. (gdb) FAIL: gdb.dwarf2/dw2-canonicalize-type.exp: ptype f (gdb) PASS: gdb.dwarf2/dw2-empty-pc-range.exp: empty range before CU load ptype realrange No symbol "realrange" in current context. (gdb) FAIL: gdb.dwarf2/dw2-empty-pc-range.exp: valid range after CU load (gdb) p N::c.C Cannot take address of method C. (gdb) FAIL: gdb.dwarf2/pr11465.exp: p N::c.C -- fix by increasing the size of the function to 4 (perhaps code in gdb/mips-tdep.c could look up code symbols up to twice, with and failing that without the ISA bit set, but it seems wrong to me to implement specific handling for invalid code just to satisfy test cases that assume too much about the target). * gdb.dwarf2/dw2-case-insensitive.exp -- an artificial code label is created, but does not work because data (a `.align' pseudo-op in this case) follows and as a result the label has no MIPS16 or microMIPS annotation in the symbol table: (gdb) PASS: gdb.dwarf2/dw2-case-insensitive.exp: set case-sensitive off info functions fUnC_lang All functions matching regular expression "fUnC_lang": File file1.txt: foo FUNC_lang(void); Non-debugging symbols: 0x004006e0 FUNC_lang_start (gdb) FAIL: gdb.dwarf2/dw2-case-insensitive.exp: regexp case-sensitive off -- fix by adding a `.insn' pseudo-op on MIPS targets; the pseudo-op marks data as instructions. * gdb.dwarf2/dw2-stack-boundary.exp -- the test case enables complaints and assumes none will be issued beyond ones explicitly arranged by the test case, however overlapping sections are noticed while minimal symbols are looked up by `mips_adjust_dwarf2_addr' in DWARF-2 record processing: (gdb) set complaints 100 (gdb) PASS: gdb.dwarf2/dw2-stack-boundary.exp: set complaints 100 file ./dw2-stack-boundary Reading symbols from ./dw2-stack-boundary...location description stack underflow...location description stack overflow...unexpected overlap between: (A) section `.reginfo' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x18) (B) section `*COM*' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x0). Will ignore section B...unexpected overlap between: (A) section `.reginfo' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x18) (B) section `*UND*' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x0). Will ignore section B...unexpected overlap between: (A) section `.reginfo' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x18) (B) section `*ABS*' from `.../gdb.dwarf2/dw2-stack-boundary' [0x0, 0x0). Will ignore section B...done. (gdb) FAIL: gdb.dwarf2/dw2-stack-boundary.exp: check partial symtab errors -- fix by ignoring any extra noise as long as what we look for is found. * gdb.cp/expand-psymtabs-cxx.exp: Accept any address of `method(long)', not just 0x0. * gdb.cp/nsalias.exp: Align code labels to 4. * gdb.dwarf2/dw2-canonicalize-type.S (main): Expand to 4-bytes. * gdb.dwarf2/dw2-empty-pc-range.S (main): Likewise. * gdb.dwarf2/pr11465.S (_ZN1N1cE): Likewise. * gdb.dwarf2/dw2-case-insensitive.c (START_INSNS): New macro. (cu_text_start, FUNC_lang_start): Use `START_INSNS'. * gdb.dwarf2/dw2-stack-boundary.exp: Accept noise in complaints. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
