[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. (elfNN_aarch64_size_stub): Support STT_SECTION symbol. (elfNN_aarch64_final_link_relocate): Take rela addend into account when calculation destination. ld/ * testsuite/ld-aarch64/farcall-section.d: Delete. * testsuite/ld-aarch64/farcall-section.s: Delete. * testsuite/ld-aarch64/farcall-b-section.d: New expectation file. * testsuite/ld-aarch64/farcall-bl-section.d: Likewise. * testsuite/ld-aarch64/farcall-b-section.s: New testcase. * testsuite/ld-aarch64/farcall-bl-section.s: Likewise. * testsuite/ld-aarch64/aarch64-elf.exp: Likewise. 2016-01-20 16:57:59 +00:00			`.global _start`
