2016-04-07ld/arc: Make little endian default choice for linker scriptsAndrew Burgess1-3/+4
When building with --enable-targets=all the target string is not set to something that matches the pattern arc*-*, and so the script used to decide if we should build big or little endian linker script currently exits with an error. This commit makes little endian linker script be the default, which will be used when building for all targets, this matches the behaviour from before I made the endianness switchable, when we only ever built little endian linker scripts anyway. ld/ChangeLog: * emulparams/arc-endianness.sh: Make little endian default choice.
2016-04-05ld/arc: Fix linker for big-endian arc targetsAndrew Burgess11-76/+16
This aims to bring the linker for big-endian arc targets into line with the linker for (the default) little endian arc targets. The bulk of the changes are to extend the target pattern in the test files from 'arc-*...' to 'arc*-*...' and so match both big and little endian arc targets. In the ld/emulparams/ directory the existing scripts checked for a variable ARC_ENDIAN to switch between big and little endian targets, however, this variable is never set up. So, a new script snippet is introduced which sets up ARC_ENDIAN based on the value of target, this snippet is then included from all of the existing arc scripts. The existing big-endian variants of all the scripts, which existed, but were never used, are deleted in this commit. ld/ChangeLog: * emulparams/arc-endianness.sh: New file. * emulparams/arcebelf.sh: Deleted. * emulparams/arcebelf_prof.sh: Deleted. * emulparams/arceblinux.sh: Deleted. * emulparams/arceblinux_prof.sh: Deleted. * emulparams/arcelf.sh: Include arc-endinness.sh. * emulparams/arcelf_prof.sh: Include arc-endinness.sh. * emulparams/arclinux.sh: Include arc-endinness.sh. * emulparams/arclinux_prof.sh: Include arc-endinness.sh. * emulparams/arcv2elf.sh: Include arc-endinness.sh. * emulparams/arcv2elfx.sh: Include arc-endinness.sh. * testsuite/ld-elf/compressed1d.d: Update pattern for big and little endian arc targets. * testsuite/ld-elf/eh-frame-hdr.d: Likewise. * testsuite/ld-elf/group1.d: Likewise. * testsuite/ld-elf/group3b.d: Likewise. * testsuite/ld-elf/group8a.d: Likewise. * testsuite/ld-elf/group8b.d: Likewise. * testsuite/ld-elf/group9a.d: Likewise. * testsuite/ld-elf/group9b.d: Likewise. * testsuite/ld-elf/linkonce2.d: Likewise. * testsuite/ld-elf/pr12851.d: Likewise. * testsuite/ld-elf/pr12975.d: Likewise. * testsuite/ld-elf/pr13177.d: Likewise. * testsuite/ld-elf/pr13195.d: Likewise. * testsuite/ld-elf/pr17615.d: Likewise. * testsuite/ld-elf/pr19162.d: Likewise. * testsuite/ld-elf/sec64k.exp: Likewise. * testsuite/lib/ld-lib.exp: Likewise.

2016-02-26[x86] Resolve non-PIC undefweak symbols in executableH.J. Lu12-2/+28
For i386 and x86-64, non-PIC references to undefined weak symbols are resolved without dynamic relocation when creating executable. Resolved undefined weak symbols are removed from the dynamic symbol table in executable. One exception is on i386, we need resolved undefined weak symbols in the dynamic symbol table in PIE if input relocatable files contain branchs without PLT so that we can branch to 0 with dynamic relocation in text section. This makes behaviors of dynamic executable and position independent executable predictable with mixed PIC and non-PIC references to undefined weak symbols. If all references to undefined weak symbols are PIC, dynamic relocations against undefined weak symbols will be generated in executable unless -z nodynamic-undefined-weak is passed to linker. bfd/ PR ld/19636 PR ld/19704 PR ld/19719 * elf32-i386.c (UNDEFINED_WEAK_RESOLVED_TO_ZERO): New.

2015-10-22Add "-z call-nop=PADDING" option to ldH.J. Lu11-0/+58
The ld linker can transform indirect call to a locally defined function, foo, via its GOT slot, to either "NOP call foo" or "call foo NOP" where NOP is a 1-byte NOP padding. This patch adds a "-z call-nop=PADDING" option to x86 ld to control 1-byte NOP padding for x86 call instruction.

2015-04-14Add -z noextern-protected-data to ld for ELF/x86H.J. Lu10-2/+22
Address of protected data defined in the shared library may be external, i.e., due to copy relocation. By default, linker backend checks if relocations against protected data symbols are valid for building shared library and issues an error if relocation isn't allowed. The new option override linker backend default. When -z noextern-protected-data is used, updates on protected data symbols by another module won't be visibile to the resulting shared library. This option is specific to ELF/i386 and ELF/x86-64. bfd/ PR ld/pr17709 * elflink.c (_bfd_elf_adjust_dynamic_copy): Check info->extern_protected_data when warning copy relocs against protected symbols.

2015-01-20Reorder more powerpc64 sections again for -z relroAlan Modra1-5/+4
.toc1 is the second level TOC section used by gcc's -mminimal-toc. It too should be read-only after relocation. Also, the last patch description mentioned .sbss moving but didn't actually do that, so fix that problem. .tocbss (whatever that is) was before .sbss previously, so move that one too. * emulparams/elf64ppc.sh (OTHER_SDATA_SECTIONS): Use in place of..

This moves .got too, which requires .sdata and .sbss to move with it, because these sections share addressing via the toc pointer and with small-model code must be within a 16-bit signed offset. .plt, .iplt and .branch_lt must also be moved since they are addressed via a 32-bit offset from the toc pointer, and we might have a very large .data section. This change means we may have some bss style sections before the data segment, necessitating another PT_LOAD header. Also, since _edata is defined at the end of the data segment it's possible with an empty .data to have _edata at the end of .plt which looks a little unusual since .plt is a bss style section. That should only happen rarely in real world binaries, but does occur in the ld testsuite. ld/ * emulparams/elf64ppc.sh (BSS_PLT): Don't define. (OTHER_READWRITE_SECTIONS): Move .branch_lt to..

2014-11-25Optimize out i386/x86-64 JUMP_SLOT relocationH.J. Lu2-1/+8
When there are both PLT and GOT references to the same function symbol, linker will create a GOTPLT slot for PLT entry and a GOT slot for GOT reference. A run-time JUMP_SLOT relocation is created to update the GOTPLT slot and a run-time GLOB_DAT relocation is created to update the GOT slot. Both JUMP_SLOT and GLOB_DAT relocations will apply the same symbol value to GOTPLT and GOT slots, respectively, at run-time. This optimization combines GOTPLT and GOT slots into a single GOT slot and removes the run-time JUMP_SLOT relocation. It replaces the regular PLT entry: indirect jump [GOTPLT slot] push relocation index jump PLT0 with an GOT PLT entry with an indirect jump via the GOT slot: indirect jump [GOT slot] nop and resolves PLT reference to the GOT PLT entry. We must avoid this optimization if pointer equality is needed since we don't clear symbol value in this case and the dynamic linker won't update the GOT slot. Otherwise, the resulting binary will get into an infinite loop at run-time. bfd/ * elf32-i386.c (elf_i386_got_plt_entry): New. (elf_i386_pic_got_plt_entry): Likewise.
