2015-04-23Don't change compressed input debug section namesH.J. Lu1-0/+7
Change compressed input debug section name for objdump is very confusing. But we need to change it for linker so that linker will consider the input section as a debug section.

2015-04-01[AArch64] Workaround for Cortex A53 erratum 843419Marcus Shawcroft1-2/+2
Some early revisions of the Cortex-A53 have an erratum (843419). The details of the erratum are quite complex and involve dynamic conditions. For the purposes of the workaround we have simplified the static conditions to an ADRP in the last two instructions of a 4KByte page, followed within four instructions by a load/store dependent on the ADRP. This patch adds support to conservatively scan for and workaround Cortex A53 erratum 843419. There are two different workaround strategies used. The first is to rewrite ADRP instructions which form part of an erratum sequence with an ADR instruction. In situations where the ADR provides insufficient offset the dependent load or store instruction from the sequence is moved to a stub section and branches are inserted from the original sequence to the relocated instruction and back again. Stub section sizes are rounded up to a multiple of 4096 in order to ensure that the act of inserting work around stubs does not create more errata sequences. Workaround stubs are always inserted into the stub section associated with the input section containing the erratum sequence. This ensures that the fully relocated form of the veneered load store instruction is available at the point in time when the stub section is written.

2015-02-14PR ld/17973 LTO file symsAlan Modra1-0/+3
LTO output objects have an STT_FILE symbol using the name of the file, a temporary file. This results in executables that can't be exactly reproduced, so the file name needs to be dropped. We don't want to lose all file symbols when linking a mix of lto and non-lto objects as a file symbol can be used to figure which source file generated a given local symbol. So lto output objects need to be marked. I chose to mark lto output objects with a new bfd flag. This flag is also used to fix a bug in the link-once handling; An object being loaded after "loading_lto_outputs" is set might be one extracted from an archive to satisfy new references from lto objects, not an lto object itself. The new flag is copied from archive to elements, and the same done for no_export. This fixes a bug in that --exclude-libs doesn't work with thin archives. I'm not completely happy with this part of the patch and may revist this to avoid the hack in _bfd_look_for_bfd_in_cache.

2015-01-19Fallout from recent bfd_reloc_outofrange changesAlan Modra1-2/+5
Commit ec93045b and cd21f5da introduced a large number of tic4x and tic54x regressions, due to the new checks being wrong for targets with octets_per_byte != 1. To fix that I introduced a new bfd_get_section_limit_octets and performed the check on octets rather than byte adresses, reducing the number of bfd_octets_per_byte calls. bfd_octets_per_byte is rather expensive.. I then wondered why the same bfd_reloc_outofrange check added to bfd_perform_relocation wasn't also added to bfd_install_relocation. The two functions are virtually identical and ought to remain that way. However, adding the same check to bfd_install_relocation resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF targets, including x64_64-linux. The reason being that eh-group.o has NONE relocs at the end of a section, and most targets give NONE relocs a non-zero size. So if we are to keep the new outofrange check it appears that NONE relocs must have a zero size. * bfd-in.h (bfd_get_section_limit_octets): New define, extracted from..

2014-09-16NDS32: Code refactoring of relaxation.Kuan-Lin Chen1-0/+27
Refactor each relaxation pattern to raise the maintainability. In origin, all patterns is analysed in nds32_elf_relax_section, so it is hard to debug and maintain. Therefore, we classify all patterns into different functions in this patch. Moreover, we adjust all optimizations into nds32_elf_relax_section to take these optimizations in turn. This can promise all relaxation being done after calling gld${EMULATION_NAME}_after_allocation.

2014-06-13Don't call bfd_link_hash_table_freeAlan Modra1-7/+0
Freeing the linker hash table is a royal pain. It can't be freed before the _bfd_write_contents call in bfd_close, because some target bfd_write_contents functions access the hash table. It can't be freed after bfd_close either, since bfd_alloc memory holding side data structures disappears (PR17047). Clearly the only place it can be freed is actually in bfd_close. This patch doesn't do that, but kills off the existing means of freeing the hash table via a bfd target xvec call. bfd/ PR 17047 * targets.c (BFD_JUMP_TABLE): Delete NAME##_bfd_link_hash_table_free.

2014-04-02Handle VDSO section headers past end of pageAlan Modra1-12/+14
When a VDSO gets large enough that it doesn't entirely fit in one page, but not so large that the part described by the program header exceeds one page, then gdb/BFD doesn't read the section headers and symbol table information. This patch cures that by passing the size of the vdso to BFD, and fixes a number of other issues in the BFD code. bfd/ * elfcode.h (bfd_from_remote_memory): Add "size" parameter. Consolidate code handling possible section headers past end of segment. Don't use p_align for page size guess, instead use minpagesize. Take note of ld.so clearing section headers when p_memsz > p_filesz. Handle file header specifying no section headers. Handle zero p_align throughout. Default loadbase to zero. Add comments. Rename contents_size to high_offset, and make it a bfd_vma.

2014-02-03ppc476 icache bug workaroundAlan Modra1-0/+1
This implements a work-around for an icache bug on 476 that can cause execution of stale instructions when control falls through from one page to the next. The idea is to prevent such fall-through by replacing the last instruction on a page with a branch to a patch area containing the instruction, then branch to the next page. The patch also fixes a number of bugs in the existing support for long branch trampolines. bfd/ * elf32-ppc.c (struct ppc_elf_link_hash_table): Add params. Delete emit_stub_syms, no_tls_get_addr_opt.

(ppc_elf_relax_section): Exclude linker created sections and those too small to hold one instruction. Don't add another branch around trampolines on later relax passes. Don't generate trampolines for undefined symbols when !relocatable, nor for plugin symbols. Allocate space for ppc476 workaround patch area. Free fixups on error return path.

2013-10-30Report overflow on PowerPC64 @h and @ha relocations.Alan Modra1-0/+6
This changes the behaviour of @h and @ha on PowerPC64 to report errors on 32-bit overflow. The motivation for this change is that on PowerPC64, most uses of @h and @ha modifiers and their corresponding relocations are to build up 32-bit offsets. We'd like to know when such offsets overflow. Only rarely do people use @h or @ha with the high 32-bit modifiers to build a 64-bit constant. Those uses will now need to use two new modifiers, @high and @higha, if the constant isn't known at assembly time. For now, we won't report overflow at assembly time.. This also fixes an error when applying some of the HIGHER and HIGHEST relocations. include/elf/ * ppc64.h (R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA, R_PPC64_TPREL16_HIGH, R_PPC64_TPREL16_HIGHA, R_PPC64_DTPREL16_HIGH, R_PPC64_DTPREL16_HIGHA): New.
