2016-05-04LD/testsuite: Add STB_GNU_UNIQUE cross-linker testMaciej W. Rozycki3-2/+19
Some targets are only really, or at least regularly, regression-tested in a crossed configuration. Currently we only have native compiled test cases for the STB_GNU_UNIQUE feature in the linker test suite. This is nice, covering run-time semantics even, but quite often not run at all. Consequently a regression may remain unnoticed for long. Add a simple test case then to provide basic linker coverage with no need for a compiler or a native toolchain. ld/ * testsuite/ld-unique/unique.d: New test. * testsuite/ld-unique/unique.exp: Run the new test.

2016-05-03[AArch64] Also puts value in place for R_AARCH64_RELATIVEJiong Wang9-1/+89
When handling absolute relocations for global symbols bind within the shared object, AArch64 will generate one dynamic RELATIVE relocation, but won't apply the value for this absolution relocations at static linking stage. This is different from AArch64 gold linker and x86-64. This is not a bug as AArch64 is RELA, there is only guarantee that relocation addend is placed in the relocation entry. But some system softwares originally writen for x86-64 might assume AArch64 bfd linker gets the same behavior as x86-64, then they could take advantage of this buy skipping those RELATIVE dynamic relocations if the load address is the same as the static linking address. This patch makes AArch64 BFD linker applies absolution relocations at static linking stage for scenario described above. Meanwhile old AArch64 android loader has a bug (PR19163) which relies on current linker behavior as a workaround, so the same option --no-apply-dynamic-relocs added.

2016-04-14arc/nps400 : New cmem instructions and associated relocationAndrew Burgess6-0/+69
Add support for arc/nps400 cmem instructions, these load and store instructions are hard-wired to access "0x57f00000 + 16-bit-offset". Supporting this relocation required some additions to the arc relocation handling in the bfd library, as well as the standard changes required to add a new relocation type. There's a test of the new instructions in the assembler, and a test of the relocation in the linker. bfd/ChangeLog: * reloc.c: Add BFD_RELOC_ARC_NPS_CMEM16 entry. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * elf32-arc.c: Add 'opcode/arc.h' include.

2016-04-07ld/arc: Make little endian default choice for linker scriptsAndrew Burgess2-3/+8
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.
