2020-05-15Fix tight loop on recursively-defined symbolsAlan Modra6-3/+48
This patch fixes a bug in GAS where the assembler enters a tight loop when attempting to resolve recursively-defined symbols, e.g. when trying to assemble "a=a". This is a regression introduced between binutils 2.32 and 2.33, by commit 1903f1385bff9 * symbols.c (struct local_symbol): Update comment. (resolve_symbol_value): For resolved symbols equated to other symbols, verify that the referenced symbol is not a local_symbol before accessing sy_value. Don't leave symbol loops during finalize_syms resolution. * testsuite/gas/all/assign-bad-recursive.d: New test. * testsuite/gas/all/assign-bad-recursive.l: Error output for test. * testsuite/gas/all/assign-bad-recursive.s: Assembly for test. * testsuite/gas/all/gas.exp: Run it.

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.

2020-04-21BFD: Exclude sections with no content from compress check.Tamar Christina3-0/+25
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. The operand checker part still uses the existing infratructure for AARCH64_OPND_BARRIER_PSB to make sure the operand is parsed correctly. gas/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * config/tc-aarch64.c (parse_barrier_psb): Update error messages to include TSB. * testsuite/gas/aarch64/system-2.d: Update -march and new tsb tests. * testsuite/gas/aarch64/system-2.s: Add new tsb tests. * testsuite/gas/aarch64/system.d: Update. opcodes/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * aarch64-asm.c (aarch64_ins_none): New. * aarch64-asm.h (ins_none): New declaration. * aarch64-dis.c (aarch64_ext_none): New. * aarch64-dis.h (ext_none): New declaration. * aarch64-opc.c (aarch64_print_operand): Update case for AARCH64_OPND_BARRIER_PSB. * aarch64-tbl.h (aarch64_opcode_table): Add tsb.
