10 daysnm: fix treating an ifunc symbol as a stab if '--ifunc-chars=--' is givenDmitry Klochkov2-3/+24
If an ifunc symbol is processed in print_symbol(), a 'type' field of a 'syminfo' structure is set to any character specified by a user with an '--ifunc-chars' option. But afterwards the 'type' field is used to check whether a symbol is a stab in print_symbol_info_{bsd,sysv}() functions in order to print additional stab related data. If the 'type' field equals '-', a symbol is treated as a stab. If '--ifunc-chars=--' is given, all ifunc symbols will be treated as stab symbols and uninitialized stab related fields of the 'syminfo' structure will be printed which can lead to segmentation fault. To fix this, check if a symbol is a stab before override the 'type' field. Also, add a test case for this fix. PR binutils/32556 * nm.c (extended_symbol_info): Add is_stab. (print_symbol): Check if a symbol is a stab. (print_symbol_info_bsd): Use info->is_stab. (print_symbol_info_sysv): Use info->is_stab. * testsuite/binutils-all/nm.exp: Test nm --ifunc-chars=--.

10 daysUse type-specific lookups in cp-support.cTom Tromey1-2/+4
cp-support.c has code to substitute types for typedef names when canonicalizing a C++ name. I believe this code can use type-specific search domains; and doing this greatly speeds up some cases. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=33081
10 daysAvoid symbol lookup for field names in C parserTom Tromey1-103/+193
Currently, the C parser looks up any name it finds -- at lex time. However, in an expression like "obj->field", looking up the field name is wasteful, and can sometimes even yield pathological symtab expansion behavior. This patch arranges to avoid the name lookup in this case. (It would be nice to really clean up this area, but I'm not convinced it can readily be done in a yacc parser.) Some special code is required for the C++ construct where a qualified name is used, like "obj->type1::type2::field". Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=33081
10 daysChange how C parser looks up type tag namesTom Tromey1-58/+79
In an earlier version of this series, Simon noticed that something like "ptype struct type" was much slower. The deep problem here is the hack in best_symbol -- in this particular case the C parser is including SEARCH_VAR_DOMAIN, which means that a type is not "best". Fixing best_symbol would be good to do, but it's difficult and I already had many struggles getting this series to this point. So, rather than fix that, I elected to modify the parser. The key insight here is that the name lookup in classify_name is useless when a tag name is expected. This patch adds a flag so that this lookup is not done. (Incidentally, this kind of thing is much more straightforward in a recursive descent parser, something like classify_name would only be applied post-lexing where appropriate.) This change speeds up the lookup by avoiding the best_symbol hack, instead searching only for a type.

10 daysgdb: Add svr4-tls-tdep.o to list of objects of i*86 targetsSergio Durigan Junior1-1/+1
GDB currently fails to build from source on i386 if compiled with --enable-64-bit-bfd. This is happening because svr4-tls-tdep.o is missing from the gdb_target_obs variable, while amd64-linux-tdep.o is obviously there. Fix the problem by adding svr4-tls-tdep.o to the object list, but only when --enable-64-bit-bfd is provided.

11 daysChange return value of _bfd_mmap_temporaryTom Tromey3-21/+19
_bfd_mmap_temporary will return MAP_FAILED in some cases, but only one caller was prepared for this. This caused a couple of issues in gdb. This patch chnages _bfd_mmap_temporary to always return NULL on failure. It also changes the logic to fall back to bfd_malloc if mmap fails. I took the opportunity to change some "(void *) -1" to MAP_FAILED where appropriate. Tested by "make check" in binutils, and also by applying a hack from bug 33354 to gdb and testing something approximating the original report.

11 daysx86: constrain and fix use of the "nojumps" .arch modifierJan Beulich7-21/+84
As said by the paragraph of the description that isn't modified here (a few lines up), this was only ever supposed to be used with 16-bit architectures. Actually enforcing this allows code in md_estimate_size_before_relax() to move to a less frequently used code path. (For backwards compatibility, keep accepting "jumps" also with 32- or 64-bit architectures.) Repeat the constraint also in the 2nd paragraph of the doc on this subject. And while there also insert a missing insn in the related i386-Jumps section. Furthermore checking a global variable during late processing is wrong. We need to record the state in the fragment, and use that rather than the state of the variable at the end of parsing all input. Seeing that there's no testing of the functionality at all, add a testcase as well.

11 daysbfd: Add i386_pe_big_vec vector to win64 targetsJeffrey Knockel1-1/+1
251dae91074170036c1a76c5e5df1f45197d7feb added i386_pe_big_vec to win32 targets but did not add it to win64 ones. Adding i386_pe_big_vec vector to win64 targets fixes an issue where a 64-bit assembler on windows would fail to create bigobj files when operating with 32-bit word size. E.g., before this change, with a 64-bit toolchain: $ echo 'int main(void) { return 100; }' \ | gcc -m32 -Wa,-mbig-obj -x c -c -o main.o - $ objdump.exe -f main.o main.o: file format pe-i386 architecture: i386, flags 0x00000039: HAS_RELOC, HAS_DEBUG, HAS_SYMS, HAS_LOCALS start address 0x00000000 But after this change, the output file format is correctly bigobj: $ echo 'int main(void) { return 100; }' \ | gcc -m32 -Wa,-mbig-obj -x c -c -o main.o - $ objdump.exe -f main.o main.o: file format pe-bigobj-i386 architecture: i386, flags 0x0000003d: HAS_RELOC, HAS_LINENO, HAS_DEBUG, HAS_SYMS, HAS_LOCALS start address 0x00000000 Although the above multilib compilation issue was the motivation for this patch, this change has other positive consequences, such as allowing the 64-bit windows build of objdump to disassemble pe-bigobj-i386 format object files, etc. Signed-off-by: Jeffrey Knockel <jeff@jeffreyknockel.com>
