Add support for sparc compare-and-branch instructions.
opcodes/ * sparc-opc.c (CBCOND): New define. (CBCOND_XCC): Likewise. (cbcond): New helper macro. (sparc_opcodes): Add compare-and-branch instructions. gas/ * config/tc-sparc.c (sparc_arch_table): Add HWCAP_CBCOND to sparc4, v8pluse, v8plusv, v9e, and v9v. (sparc_ip): Handle R_SPARC_5 of immediate constants inline in order to accomodate cbcond which otherwise would require two relocations to be handled in a single instruction.. gas/testsuite/ * gas/sparc/cbcond.s: New file. * gas/sparc/cbcond.d: New file. * gas/sparc/sparc.exp: Run cbcond test.
