2020-04-27x86: Add i386 PE big-object supportTamar Christina6-5/+15
The 64-bit version of binutils got support for the PE COFF BIG OBJ format a couple of years ago. The BIG OBJ format is a slightly different COFF format which extends the size of the number of section field in the header from a uint16_t to a uint32_t and so greatly increases the number of sections allowed. However the 32-bit version of bfd never got support for this. The GHC Haskell compiler generates a great deal of symbols due to it's use of -ffunction-sections and -fdata-sections. This meant that we could not build the 32-bit version of the GHC Compiler for many releases now as binutils didn't have this support. This patch adds the support to the 32-bit port of binutils as well and also does come cleanup in the code. bfd/ChangeLog: * coff-i386.c (COFF_WITH_PE_BIGOBJ): New. * coff-x86_64.c (COFF_WITH_PE_BIGOBJ): New. * config.bfd (targ_selvecs): Rename x86_64_pe_be_vec to x86_64_pe_big_vec as it not a big-endian format.

The check in bfd_get_full_section_contents is trying to check that we don't allocate more space for a section than the size of the section is on disk. Previously we excluded linker created sections since they didn't have a size on disk. However we also need to exclude sections with no content as well such as the BSS section. Space for these would not have been allocated by the assembler and so the check would incorrectly fail. bfd/ChangeLog: PR binutils/24753 * compress.c (bfd_get_full_section_contents): Exclude sections with no content. gas/ChangeLog: PR binutils/24753 * testsuite/gas/arm/pr24753.d: New test. * testsuite/gas/arm/pr24753.s: New test.

2020-04-20[AArch64, Binutils] Add missing TSB instructionSudakshina Das5-9/+25
This patch implements the TSB instructions: https://developer.arm.com/docs/ddi0596/f/base-instructions-alphabetic-order/ tsb-csync-trace-synchronization-barrier Since TSB and PSB both use the same (and only) argument "CSYNC", this patch reuses it for TSB. However, the same argument would imply different value for CRm:Op2 which are anyway fixed values, so I have diverted the inserter/extracter function to dummy versions instead of the "hint" version.

2020-04-02ld: Disable ifunc tests on SolarisRainer Orth5-4/+11
A couple of ld ifunc tests currently FAIL on 64-bit Solaris/x86: FAIL: ld-ifunc/ifunc-10-x86-64 FAIL: ld-ifunc/ifunc-11-x86-64 FAIL: ld-ifunc/ifunc-12-x86-64 FAIL: ld-ifunc/ifunc-13-x86-64 FAIL: ld-ifunc/ifunc-14a-x86-64 FAIL: ld-ifunc/ifunc-14b-x86-64 FAIL: ld-ifunc/ifunc-14c-x86-64 FAIL: ld-ifunc/ifunc-14d-x86-64 FAIL: ld-ifunc/ifunc-14e-x86-64 FAIL: ld-ifunc/ifunc-14f-x86-64 FAIL: ld-ifunc/ifunc-15-x86-64 FAIL: ld-ifunc/ifunc-17a-x86-64 FAIL: ld-ifunc/ifunc-17b-x86-64 FAIL: ld-ifunc/ifunc-2-local-x86-64-now FAIL: ld-ifunc/ifunc-2-local-x86-64 FAIL: ld-ifunc/ifunc-2-x86-64-now FAIL: ld-ifunc/ifunc-2-x86-64 FAIL: ld-ifunc/ifunc-20-x86-64 FAIL: ld-ifunc/pr17154-x86-64-now FAIL: ld-ifunc/pr17154-x86-64 For one, the actual error is weird: ./ld-new: target elf64-x86-64 not found failed with: <./ld-new: target elf64-x86-64 not found>, no expected output FAIL: ld-ifunc/ifunc-10-x86-64 although ld -V does report the elf_x86_64 emulation as supported: $ ./ld/ld-new -V GNU ld (GNU Binutils) 2.34.50.20200328 Supported emulations: elf_x86_64_sol2 elf_x86_64 [...] When using ld -m elf_x86_64_sol2 instead, one of the testcases links successfully. However, there's no point in pursuing this: Solaris does not support ifunc, as can be seen in <sys/elf.h>: /* * GNU/Linux specific symbol type not used by Solaris */ #define STT_GNU_IFUNC 10 and never will, given that it has symbol capabilities as solution to effectively the same problem: http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/ Therefore this patch disables ifunc testing on Solaris completely by removing Solaris from binutils/testsuite/lib/binutils-common.exp (supports_gnu_osabi). The ifunc part is justified above. SHF_GNU_MBIND is in the OS-specific range and conflicts with #define SHF_SUNW_REALLOC 0x01000000 /* internal: krtld realloc */ While the comment suggests this might be relocatable without too much problems, the description of mbind (no formal spec AFAICS, just the comment in the binutils patch submission) strongly suggests that this isn't relevant to Solaris at all. Indirectly, clearing supports_gnu_osabi on Solaris disables supports_gnu_unique. Again, Solaris <sys/elf.h> has /* * GNU/Linux specific binding not used by Solaris */ #define STB_GNU_UNIQUE 10 so this seems the right thing to do. Afterwards, one can remove the explicit mentions of *-*-solaris2* in quite a number of (but not all) the ld-ifunc dump file notarget lists. There's one fallout, though: two gas tests now XPASS because they are xfail'ed for !supports_gnu_osabi: XPASS: mbind sections 12 XPASS: mbind section contents 16 XPASS: mbind sections 16 XPASS: mbind section contents 16 To fix that, I've changed #xfail: ![supports_gnu_osabi] to notarget.

2020-04-01gas: Fix some x86_64 testcases for Solaris not using R_X86_64_PLT32 [PR25732]Rainer Orth8-47/+92
As reported in PR gas/25732, some testcases currently FAIL on Solaris/x86: FAIL: x86-64 branch 2 FAIL: x86-64 branch 3 FAIL: x86-64 MPX branch FAIL: x86-64 branch with BND prefix FAIL: x86-64 jump Since https://sourceware.org/ml/binutils/2019-03/msg00163.html, gas doesn't emit R_X86_64_PLT32 as branch marker on Solaris. Since the testsuite lacks a way to preprocess dump files, adjusted copies of the affected dumps are now used on Solaris. Unfortunately, those dumps weren't adapted when the original testcases were changed or other testcases started to differ between non-Solaris and Solaris targets. The following patch fixes that, re-syncing the affected dump files or creating new Solaris-specific ones. Tested on i386-pc-solaris2.11, x86_64-pc-solaris2.11, x86_64-pc-linux-gnu, and i686-pc-linux-gnu.
