2021-03-29TRUE/FALSE simplificationAlan Modra1-3/+3
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.

2021-03-29elf_backend_relocate_section int vs. bfd_booleanAlan Modra1-1/+1
This functions was changed to return an int in commit ece5ef60797f but since bfd_boolean was an int typedef I lazily left all the ELF relocate_section functions as returning bfd_boolean, except the SPU one.

Which would make it jump and transition out of thumb mode and crash since you only have thumb mode on such cores. Now it correctly generates Hex dump of section '.got': ... 0x000101b8 40010100 00000000 00000000 11010000 @............... Thanks to Amol for testing patch and to rgujju for reporting it. bfd/ChangeLog: PR ld/16017 * elf32-arm.c (elf32_arm_populate_plt_entry): Set LSB of the PLT0 address in the GOT if in thumb only mode. ld/ChangeLog: PR ld/16017 * testsuite/ld-arm/arm-elf.exp (thumb-plt-got): New. * testsuite/ld-arm/thumb-plt-got.d: New test.
2020-04-01Arm: Fix thumb2 PLT branch offsets.Tamar Christina1-2/+2
When I previously changed these offsets I had incorrectly used an offset of -2 for this Thumb2 PLT. Unfortunately because we had no tests for this PLT I had missed that the result was incorrect. This patch fixes the offset to PC .-4 so that it correctly addresses the previous instruction and adds a test for this PLT stub. bfd/ChangeLog: * elf32-arm.c (elf32_thumb2_plt_entry): Fix PC-rel offset. ld/ChangeLog: * testsuite/ld-arm/arm-elf.exp (thumb-plt): New. * testsuite/ld-arm/thumb-plt.d: New test. * testsuite/ld-arm/thumb-plt.s: New test.

2020-03-02elf_backend_section_flags and _bfd_elf_init_private_section_dataAlan Modra1-2/+2
I was looking at elf_backend_section_flags as a means of setting SEC_SMALL_DATA for .sdata, .sbss and the like, and condidered adding an asection* parameter to access the section name easily before realising that hdr->bfd_section of course makes the section available. So no new parameter needed. In fact the flagword* parameter isn't needed either, so out it goes. The patch also tidies some horrible code in _bfd_elf_new_section_hook that can change whether known ABI sections have sh_type and sh_flags set up depending on which of the bfd_make_section functions is used. (Some of those set section flags before _bfd_elf_new_section_hook is called, others leave the flags zero.) The function also had some hacks for .init_array and .fini_array to affect how _bfd_elf_init_private_section_data behaved for those sections. It's cleaner to do that in _bfd_elf_init_private_section_data. So that all goes and we now init sh_type and sh_flags for all known ABI sections in _bfd_elf_new_section_hook. _bfd_elf_init_private_section_data is changed to suit, and now doesn't just single out SHT_INIT_ARRAY and SHT_FINI_ARRAY but rather any of the special section types. The _bfd_elf_new_section_hook change resulting in +FAIL: ld-aarch64/erratum835769-843419 exposing some errors in the aarch64 backend. elfNN_aarch64_size_stubs should not be looking at linker created sections in the stub bfd.

2020-02-19bfd_size_type to size_tAlan Modra1-4/+4
bfd_size_type was invented a long time ago in the K&R days. Many places in binutils ought to be using size_t instead (and there are lots of places that use long or unsigned long that really ought to use size_t too). Note that you can't change everything over to size_t: A 32-bit host needs a larger type than size_t to support reading and processing of 64-bit ELF object files. This patch just tidies some of the more obvious uses of bfd_size_type that could be size_t. There no doubt are more lurking in the source. Incidentally, practically all functions used for output of object files can use size_t and don't need to worry about overflow of size expressions. If you have something like symcount * sizeof (void *) when symcount is counting symbols already in memory then you know that this expression can't overflow since the size of a symbol in memory is larger by far than that of a pointer. * aix386-core.c (aix386_core_file_p): Use size_t for "amt". * aout-target.h (object_p): Likewise. * aout-tic30.c (tic30_aout_object_p): Likewise. * aoutx.h

2019-11-27PR23652, Use symbols from debug bfd for _bfd_elf_find_functionAlan Modra1-111/+30
Sometimes DWARF info for a function is incomplete, and the function can be retrieved by examining symbols. However, when separate debug files are used it may be that the original file is completely stripped of symbols. This patch teaches BFD to look at symbols from the debug file in that case. The patch also removes arm_elf_find_function, instead implementing elf_backend_maybe_function_sym. arm_elf_find_function was written before the generic _bfd_elf_find_function called maybe_function_sym. aarch64 copied arm, so that file gets the same treatment. There is some chance this will speed up arm and aarch64 lookup of function/line. PR 23652 * dwarf2.c (_bfd_dwarf2_stash_syms): New function.

2019-11-21ARM cmse_scan segfaultAlan Modra1-2/+5
This code in elf_link_add_object_symbols: ret = elf_add_dt_needed_tag (abfd, info, soname, add_needed); if (ret < 0) goto error_return; /* If we have already included this dynamic object in the link, just ignore it. There is no reason to include a particular dynamic object more than once. */ if (ret > 0) return TRUE; prevents a shared library from being loaded twice by ensuring that any library soname doesn't match the soname of one already loaded.

Dynamic relocs are only needed in an executable for TLS symbols if those are defined in an external module and even then TLS access can be relaxed to use IE model instead of GD. Several bfd_link_pic checks are turned into bfd_link_dll checks to fix TLS handling in PIE, for the same fix some other targets used !bfd_link_executable checks, but that includes relocatable objects so dll seems safer (in most cases either should work, since dynamic relocations are not applied in relocatable objects).

2019-09-19bfd_section_* macrosAlan Modra1-13/+14
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

2019-08-22ARM CMSE symbolsAlan Modra1-20/+6
This patch removes use of st_target_internal to cache the result of comparing symbol names against CMSE_PREFIX. The problem with setting a bit in st_target_internal in swap_symbol_in is that calling bfd_elf_sym_name from swap_symbol_in requires symtab_hdr, and you don't know for sure whether swap_symbol_in is operating on dynsyms (and thus elf_tdata (abfd)->dynsymtab_hdr should be used) or on the normal symtab (thus elf_tdata (abfd)->symtab_hdr). You can make an educated guess based on abfd->flags & DYNAMIC but that relies on knowing a lot about calls to bfd_elf_get_elf_syms, and is fragile in the face of possible future changes. include/ * elf/arm.h (ARM_GET_SYM_CMSE_SPCL, ARM_SET_SYM_CMSE_SPCL): Delete. bfd/ * elf32-arm.c (cmse_scan): Don't use ARM_GET_SYM_CMSE_SPCL, instead recognize CMSE_PREFIX in symbol name.

For this reason this patch changes the NOPs after Thumb to Arm veneers into B .-2 and adds a note to this in the source code for future reference. bfd/ChangeLog: * elf32-arm.c (elf32_thumb2_plt_entry, elf32_arm_plt_thumb_stub, elf32_arm_stub_long_branch_v4t_thumb_thumb, elf32_arm_stub_long_branch_v4t_thumb_arm, elf32_arm_stub_short_branch_v4t_thumb_arm, elf32_arm_stub_long_branch_v4t_thumb_arm_pic, elf32_arm_stub_long_branch_v4t_thumb_thumb_pic, elf32_arm_stub_long_branch_v4t_thumb_tls_pic): Change nop to branch to previous instruction. ld/ChangeLog: * testsuite/ld-arm/cortex-a8-fix-b-plt.d: Update Testcase. * testsuite/ld-arm/cortex-a8-fix-b-rel-arm.d: Likewise. * testsuite/ld-arm/cortex-a8-fix-bcc-plt.d: Likewise. * testsuite/ld-arm/farcall-cond-thumb-arm.d: Likewise. * testsuite/ld-arm/farcall-mixed-app.d: Likewise. * testsuite/ld-arm/farcall-mixed-app2.d: Likewise. * testsuite/ld-arm/farcall-mixed-lib-v4t.d: Likewise. * testsuite/ld-arm/farcall-thumb-arm-pic-veneer.d: Likewise. * testsuite/ld-arm/farcall-thumb-arm-short.d: Likewise. * testsuite/ld-arm/farcall-thumb-arm.d: Likewise. * testsuite/ld-arm/farcall-thumb-thumb-pic-veneer.d: Likewise. * testsuite/ld-arm/farcall-thumb-thumb.d: Likewise. * testsuite/ld-arm/fix-arm1176-on.d: Likewise. * testsuite/ld-arm/ifunc-10.dd: Likewise. * testsuite/ld-arm/ifunc-2.dd: Likewise. * testsuite/ld-arm/ifunc-4.dd: Likewise. * testsuite/ld-arm/ifunc-6.dd: Likewise. * testsuite/ld-arm/ifunc-8.dd: Likewise. * testsuite/ld-arm/jump-reloc-veneers-long.d: Likewise. * testsuite/ld-arm/mixed-app.d: Likewise. * testsuite/ld-arm/thumb2-b-interwork.d: Likewise. * testsuite/ld-arm/tls-longplt.d: Likewise. * testsuite/ld-arm/tls-thumb1.d: Likewise.
2019-08-14Remove _bfd_dwarf2_find_nearest_line addr_size parameterAlan Modra1-1/+1
This parameter might appear to be used to set up offset_size, but since git commit 024b2372f5 offset_size is either set from the debug_info data or is set to 4. * dwarf2.c (_bfd_dwarf2_find_nearest_line): Remove addr_size parameter. * libbfd-in.h (_bfd_dwarf2_find_nearest_line): Update prototype. * coffgen.c (coff_find_nearest_line_with_names): Adjust _bfd_dwarf2_find_nearest_line calls. * elf.c (_bfd_elf_find_nearest_line, _bfd_elf_find_line): Likewise. * elf32-arm.c (elf32_arm_find_nearest_line): Likewise. * elf64-alpha.c (elf64_alpha_find_nearest_line): Likewise. * elfnn-aarch64.c (elfNN_aarch64_find_nearest_line): Likewise. * elfxx-mips.c (_bfd_mips_elf_find_nearest_line): Likewise. * mach-o.c (bfd_mach_o_find_nearest_line): Likewise. * libbfd.h: Regenerate.
