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.
