2016-09-27Don't treat as separate symbols if unversioned symbol is undefined.Cary Coutant2-0/+7

This patch rewrites the rather obscure can_add_to_stub_group, fixing a problem with the handling of sections containing conditional external branches.

2016-08-10Fix improper handling of R_SPARC_GOTDATA_OP_LOX10 relocation.James Clarke2-7/+13
The fall-through in Target_sparc::Relocate::relocate for R_SPARC_GOTDATA_OP_LOX10 is currently R_SPARC_GOT13, but should clearly be R_SPARC_GOT10. GCC has been seen to emit a sethi/xor rather than a sethi/or sequence to load a 32-bit immediate, but if R_SPARC_GOT13 is used then bits 10-12 get zeroed out as both the sethi and xor immediates contain them. gold/ PR gold/20442 * sparc.cc (Target_sparc::Relocate::relocate): R_SPARC_GOTDATA_OP_LOX10 should fall back on R_SPARC_GOT10, not R_SPARC_GOT13.
