2016-05-19Remove unsupported `am34-*-linux*' target tripletMaciej W. Rozycki2-1/+4
The `am34-*-linux*' target cannot be configured for, `am34' is not a CPU name recognized by `config.sub'. It has never been, required code has not been contributed to GNU config, neither before nor since the addition of the target triplet to our configury with commit bfff16424942 ("Add MN10300 linker relaxation support for symbol differences") back in 2007. Also there is no difference in actual tool configuration between the `am34-*-linux*' and `am33_2.0-*-linux*' targets, except from a different executable prefix and tooldir name. Given the above remove the target triplet from our configuration. bfd/ * config.bfd: Remove `am34-*-linux*' support. ld/ * configure.tgt: Remove `am34-*-linux*' support.

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.

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.
