2021-04-05C99 bfd configuryAlan Modra19-1962/+636
Certain library headers and functions are required by C99. This removes configure tests for them. The patch also removes AC_ISC_POSIX and AC_HEADER_DIRENT, which the autoconf manual states are obsolescent. sys/time.h is no longer tangled up with time.h so it can be handled by the gprof configure. * configure.ac: Don't check for long long or long double type. Don't check for alloca.h, limits.h, stddef.h, stdlib.h, string.h, strings.h, time.h, wchar.h, wctype.h or sys/time.h. Don't check for strtoull, free, malloc, realloc, getenv, strstr, snprintf, vsnprintf, strlen or setitimer. Sort AC_CHECK_DECLS. (AC_ISC_POSIX): Don't invoke. (AC_HEADER_TIME, AC_HEADER_DIRENT, ACX_HEADER_STRING): Likewise. * sysdep.h: Remove many HAVE_*_H checks and fallback declarations. Do test HAVE_SYS_TYPES_H. Don't include sys/time.h. Reorder header order as per automake AC_INCLUDES_DEFAULT. * bfd-in.h: Include inttypes.h unconditionally. * bfd.c (_bfd_doprnt, _bfd_doprnt_scan): Assume long long and long double are available.

2021-04-01PE/Windows x86_64: Fix weak undef symbols after image base changeTamar Christina2-0/+20
The change in PR19011 changed the image load address from being in the lower 32-bit address space to the higher 64-bit address space. However when you have a weak undef symbol which stays undef at the end of linking the linker has to resolve this (Windows loader does not support undef symbols). As such typically these would resolve to 0. The relocation used for these weak symbols are the normal 32-bit PC_REL call relocs. So when doing the overflow check LD checks if the distance between the symbol and the call is within range. However now that the load address is > 32-bits and the symbol val is 0 this overflow check will always fail. As such the linker gives a bogus error. This patch makes the linker not emit the overflow failure but chooses to still let the check be performed (as it's mid-end code). One down side of this is that it does break the common convention that the call be to sym at 0x0. i.e. before you'd get 401015: 74 05 je 40101c 401017: e8 e4 ef bf ff callq 0 and now you get 140001015: 74 05 je 14000101c 140001017: e8 e4 ef ff bf call 100000000 since the call is PC_REL there's no way to get the range large enough to resolve to 0. As such I have chosen to leave it as the furthest simple range that we can still represent. By only ignoring the error we leave the symbol value itself to still be 0 such that the if(<symbol>) checks still work correctly. bfd/ChangeLog: 2021-04-01 Tamar Christina <tamar.christina@arm.com> PR ld/26659 * cofflink.c (_bfd_coff_generic_relocate_section): Ignore overflow. ld/ChangeLog: 2021-04-01 Tamar Christina <tamar.christina@arm.com> PR ld/26659 * testsuite/ld-pe/pe.exp: Add test. * testsuite/ld-pe/pr26659-weak-undef-sym.d: New test. * testsuite/ld-pe/pr26659-weak-undef-sym.s: New test.

2021-03-29TRUE/FALSE simplificationAlan Modra11-20/+37
There is really no need to write code like "foo != 0 ? TRUE : FALSE" unless we had stupidly defined FALSE as something other than 0 or TRUE as something other than 1. The simpler "foo != 0" does just as well. Similarly "(condition == TRUE)" or "(condition == FALSE) can be simplified to "(condition)" and "(!condition)" respectively. I'll note that there is reason to use "integer_expression != 0" when assigning a bfd_boolean rather than the simpler "integer_expression", if you expect the variable to have 0 or 1 value. It's probably even a good idea to not rely on implicit conversion if bfd_boolean were _Bool. bfd/ * aoutx.h (aout_link_write_symbols): Don't cast boolean expression to bfd_boolean. * elf32-or1k.c (or1k_set_got_and_rela_sizes): Dont compare booleans against FALSE. * elf32-arc.c (name_for_global_symbol): Don't compare boolean to TRUE.

2021-03-26Save/restore file offset while reading notes in core fileKeith Seitz2-0/+12
A recent bug (RH BZ 1931344) has exposed a bug in the core file build-ID support that I introduced a while ago. It is pretty easy to demonstate the problem following a simplified procedure outlined in that bug: [shell1] shell1$ /usr/libexec/qemu-kvm [shell2] shell2$ pkill -SEGV -x qemu-kvm [shell1] Segmentation fault (core dumped) Load this core file into GDB without specifying an executable (an unfortunate Fedora/RHEL-ism), and GDB will inform the user to install debuginfo for the "missing" executable: $ gdb -nx -q core.12345 ... Missing separate debuginfo for the main executable file Try: dnf --enablerepo='*debug*' install /usr/lib/debug/.build-id/e2/e9c66d3117fb2bbb5b2be122f04f2664e5df54 Core was generated by `/usr/libexec/qemu-kvm'. Program terminated with signal SIGSEGV, Segmentation fault. ... The suggested build-ID is actaully for gmp not qemu-kvm. The problem lies in _bfd_elf_core_find_build_id, where we loop over program headers looking for note segments: /* Read in program headers and parse notes. */ for (i = 0; i < i_ehdr.e_phnum; ++i, ++i_phdr) { Elf_External_Phdr x_phdr; if (bfd_bread (&x_phdr, sizeof (x_phdr), abfd) != sizeof (x_phdr)) goto fail; elf_swap_phdr_in (abfd, &x_phdr, i_phdr); if (i_phdr->p_type == PT_NOTE && i_phdr->p_filesz > 0) { elf_read_notes (abfd, offset + i_phdr->p_offset, i_phdr->p_filesz, i_phdr->p_align); if (abfd->build_id != NULL) return TRUE; } elf_read_notes uses bfd_seek to forward the stream to the location of the note segment. When control returns to _bfd_elf_core_fild_build_id, the stream is no longer in the location looking at program headers, and all subsequent reads will read from the wrong file offset. To fix this, this patch marks the stream location and ensures that it is restored after elf_read_notes is called. bfd/ChangeLog 2021-03-26 Keith Seitz <keiths@redhat.com> * elfcore.h (_bfd_elf_core_find_build_id): Seek file offset of program headers after calling elf_read_notes.

2021-03-12aix: implement TLS relocation for gas and ldClément Chigot10-36/+456
Add support for TLS in XCOFF. Amongst the things done by this commit: - Update XCOFF auxialiary header to match new version and allow TLS sections. - Add TLS sections (.tdata and .tbss) support in gas and ld. - Add support for the TLS relocations in gas and ld. Two different types BFD_RELOC are created for PPC and PPC64 as the size is a pointer, thus distinct in 32 or 64bit. The addresses given by ld to .tdata and .tbss is a bit special. In XCOFF, these addresses are actually offsets from the TLS pointer computed at runtime. AIX assembly and linker does the same. In top of that, the .tdata must be before .data (this is mandatory for AIX loader). Thus, the aix ld script is recomputing "." before .data to restore its original value. There might be a simpler way, but this one is working. Optimisation linked to TLS relocations aren't yet implemented. bfd/ * reloc.c (BFD_RELOC_PPC_TLS_LE, BFD_RELOC_PPC_TLS_IE, BFD_RELOC_PPC_TLS_M, BFD_RELOC_PPC_TLS_ML, BFD_RELOC_PPC64_TLS_GD, BFD_RELOC_PPC64_TLS_LD, BFD_RELOC_PPC64_TLS_LE, BFD_RELOC_PPC64_TLS_IE, BFD_RELOC_PPC64_TLS_M, BFD_RELOC_PPC64_TLS_ML): New relocations. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * coff-rs6000.c (xcoff_calculate_relocation): Call xcoff_reloc_type_tls for TLS relocations.
