2020-02-02ELF: Add support for unique section ID to assemblerH.J. Lu4-7/+14
Clang's integrated assembler supports multiple section with the same name: .section .text,"ax",@progbits,unique,1 nop .section .text,"ax",@progbits,unique,2 nop "unique,N" assigns the number, N, as the section ID, to a section. The valid values of the section ID are between 0 and 4294967295. It can be used to distinguish different sections with the same section name. This is useful with -fno-unique-section-names -ffunction-sections. -ffunction-sections by default generates .text.foo, .text.bar, etc. Using the same string can save lots of space in .strtab. This patch adds section_id to bfd_section and reuses the linker internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler internal use to mark valid section_id. It also updates objdump to compare section pointers if 2 sections comes from the same file since 2 different sections can have the same section name. bfd/ PR gas/25380 * bfd-in2.h: Regenerated. * ecoff.c (bfd_debug_section): Add section_id. * section.c (bfd_section): Add section_id.

2020-01-22PowerPC64 __tls_get_addr_descAlan Modra18-8/+1191
This implements register saving and restoring in the __tls_get_addr call stub, so that when glibc supports the optimized tls call stub gcc can generate code that assumes only r0, r12 and of course r3 are changed on a __tls_get_addr call.

2020-01-20x86-64: Fix TLSDESC relaxation for x32H.J. Lu17-0/+466
For x32, we must encode "lea x@TLSDESC(%rip), %reg" with a REX prefix even if it isn't required. Otherwise linker can’t safely perform GDesc -> IE/LE optimization. X32 TLSDESC sequences can be: 40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg ... 67 ff 10 call *x@TLSCALL(%eax) or the same sequence as LP64: 48 8d 05 00 00 00 00 lea foo@TLSDESC(%rip), %reg ... ff 10 call *foo@TLSCALL(%rax) We need to support both sequences for x32. For both GDesc -> IE/LE transitions, 67 ff 10 call *x@TLSCALL(%eax) should relaxed to 0f 1f 00 nopl (%rax) For GDesc -> LE transition, 40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg should relaxed to 40 c7 c0 fc ff ff ff rex movl $x@tpoff, %reg For GDesc -> IE transition, 40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg should relaxed to 40 8b 05 00 00 00 00 rex movl x@gottpoff(%rip), %eax bfd/ PR ld/25416 * elf64-x86-64.c (elf_x86_64_check_tls_transition): Support "rex leal x@tlsdesc(%rip), %reg" and "call *x@tlsdesc(%eax)" in X32 mode.

2020-01-02AArch64: Set the correct ELF class for AArch64 stubs (PR/25210)Tamar Christina4-1/+65
This fixes PR 25210 by specifying the the correct ELF class for AArch64 stubs. After doing this the stub section starts behaving like a normal object file loaded from disk. That is SEC_LINKER_CREATED causes us to have to write the section manually. This flag was added as a fix for PR 24753. I believe that fix to still be correct as linker created sections don't have a size on disk and it fixes the Arm bootstrap regression. But in this case specifying the correct section class also makes the stub section not be considered by compress.c. So I'm partially revert this change so that we don't have to manage the section manually as implied by SEC_LINKER_CREATED. bfd/ChangeLog: PR 25210 PR 24753 * elfnn-aarch64.c (_bfd_aarch64_create_stub_section): Set ELF class. ld/ChangeLog: PR 25210 PR 24753 * emultempl/aarch64elf.em (elf${ELFSIZE}_aarch64_add_stub_section): Remove SEC_LINKER_CREATED. * testsuite/ld-aarch64/aarch64-elf.exp: Add erratum835769-843419. * testsuite/ld-aarch64/erratum835769-843419.d: New test.

2019-12-26Avoid ubsan bug complaining about &p->fieldAlan Modra9-25/+44
I reckon it's quite OK to write &p->field in C when p might be NULL, and lots of old C programmers probably agree with me. However, ubsan disagrees and so do some people I respect. I suspect C++ influence is to blame for the ubsan behaviour. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92634. So far no one has educated me as to why I'm wrong to claim that there isn't anything in the C standard to say that p->field is always (*p).field. Note 79 doesn't quite do that because it doesn't cover null pointers. If there was such an equivalence then you could claim &p->field has a null pointer reference when p is NULL, even though no C compiler would ever dereference p. Anyway, to silence ubsan I'm going to apply the following though I prefer to avoid casts when possible. And I'm using (void *) deliberately because this is C, not C++! * ldlang.c (lang_output_section_find_by_flags): Don't use &p->field when p might be NULL. * ldelf.c (output_rel_find, ldelf_place_orphan): Likewise.

2019-12-17Prefer object over notype symbols when disassemblingAlan Modra41-25/+117
Changing objdump disassembly output like this always requires some testsuite changes, with the avr and x64_64 changes simply due to picking up better symbols, the whole point of the patch. The mips changes are due to mips-sgi-irix changing STT_NOTYPE symbols to STT_OBJECT, which objdump now chooses in preference to script symbols. The problem is that objdump looks at the first symbol in the section being disassembled, and if object type, just dumps out bytes rather than disassembling. This results in new failures: FAIL: JAL overflow 2 FAIL: undefined weak symbol overflow FAIL: undefined weak symbol overflow (n32) FAIL: undefined weak symbol overflow (n64) So for mips-sgi-irix function symbols really do need to be function type. I fixed a few more than just the required minimum to avoid the above test fails. binutils/ * objdump.c (compare_section): New static var. (compare_symbols): Sort by current section only. Don't access symbol name out of bounds when checking for file symbols. Sort section symbols and object symbols. (find_symbol_for_address): Remove bogus debugging and section symbol test.
