Store estimated istrances in compressed_size elf_x86_64_convert_load is very time consuming since it is called on each input section and has a loop over input text sections to estimate the branch distrance. We can store the estimated distrances in the compressed_size field of the output section, which is only used to decompress the compressed input section.

[AArch64] Relax long branch veneer insertion for non STT_FUNC symbol As defined at AArch64 ELF Specification (4.6.7 Call and Jump relocations), symbol with type of non STT_FUNC but in different input section with relocation place should insert long branch veneer also. Meanwhile the current long branch veneer infrastructure havn't considered the situation where the branch destination is "sym_value + rela->addend". This was OK because we only insert veneer for long call destination is STT_FUNC symbol for which the addend is always zero. But as we relax the support to other situations by this patch, we need to handle addend be non-zero value. For example, for static function, relocation against "local symbol" are turned into relocation against "section symbol + offset" where there is a valid addend. bfd/ * elfnn-aarch64.c (aarch64_type_of_stub): Allow insert long branch veneer for sym_sec != input_sec.

bfd/arc: Add R_ prefix to all relocation names The convention within for relocation names is that they start with the string "R_", however, this is not so for ARC for the display names of relocations, however, internally, the names for the relocations types do have the 'R_' prefix. I suspect that the missing 'R_' on the output strings was an oversight, as I can't see any comment to the contrary. To bring ARC into line with other targets, this commit adds the 'R_' prefix to the output strings used for relocation names, and updates all of the assembler tests where this was exposed. bfd/ChangeLog: * elf32-arc.c (reloc_type_to_name): Change ARC_RELOC_HOWTO to place 'R_' before the reloc name returned.

MIPS/BFD: Move attribute check after ELF file header flag check We have a problem in that in making compatibility checks while merging private BFD data on the MIPS target we give priority to the attribute check, which may fail and cause the function to abort early on. The problem with this is the ABI compatibility aspect recorded in the attributes is relatively minor compared to aspects recorded in the ELF file header. However the premature exit causes any more important compatibility aspect violated to be masked and not reported to the user once a problem with attributes has been noticed. So move the attribute check after the ELF file header flag check in `_bfd_mips_elf_merge_private_bfd_data', and do not return prematurely there. Take advantage of the resulting grouping of ELF file header handling together and remove the premature success return point for the first input object being handled, letting the code later on figure out output ABI flags even for this object. Update LD test cases according to messages from ELF file header checks now preceding ones from attribute checks. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Move attribute check after ELF file header flag check. ld/ * testsuite/ld-mips-elf/attr-gnu-4-14.d: Update the order of messages expected according to MIPS BFD private data merge changes. * testsuite/ld-mips-elf/attr-gnu-4-24.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-34.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-41.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-42.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-43.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-45.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-46.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-47.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-48.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-49.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-54.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-64.d: Likewise. * testsuite/ld-mips-elf/attr-gnu-4-74.d: Likewise.

MIPS/BFD: Fold the handling of input MIPS ABI flags together Fold the handling of input MIPS ABI flags in private BFD data merging together, moving the attribute check afterwards, and consequently making input vs output compatibility checks only start once all input ABI flag data has been gathered, checked for inconsistencies and put in order. Consequently also address the issue of input ABI flag inconsistencies being masked by a failing attribute check, which currently makes `_bfd_mips_elf_merge_private_bfd_data' exit prematurely and therefore prevent input ABI flag inconsistencies from being reported. Such inconsistencies need to be reported as they may be the very cause of an attribute check failure. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Fold the handling of input MIPS ABI flags together.

MIPS/BFD: Suppress attribute checks for null input We currently special-case the handling of attribute checks on input objects and make them even before we check a given input object actually contains any sections. This does not add value as empty objects do not cause a compatibility concern and we already make this observation for other properties such as ELF file header flags. Moreover the attributes themselves are stored in a `.gnu.attributes' section so the absence of any section (except from a few special cases) implies there have been no attributes provided either. Therefore it is safe to move the attribute checks later on, after the null-section check has been made. bfd/ * elfxx-mips.c (_bfd_mips_elf_merge_private_bfd_data): Suppress attribute checks for null input.
