2005-01-31 Jan Beulich <jbeulich@novell.com> * config/tc-ia64.c (parse_operands): Also handle alloc without first input being ar.pfs. gas/testsuite/ 2005-01-31 Jan Beulich <jbeulich@novell.com> * gas/ia64/pseudo.[ds]: New. * gas/ia64/ia64.exp: Run new test. opcodes/ 2005-01-31 Jan Beulich <jbeulich@novell.com> * ia64-gen.c (NELEMS): Define. (shrink): Generate alias with missing second predicate register when opcode has two outputs and these are both predicates. * ia64-opc-i.c (FULL17): Define. (ia64_opcodes_i): Add mov-to-pr alias without second input. Use FULL17 here to generate output template. (TBITCM, TNATCM): Undefine after use. * ia64-opc-m.c (ia64_opcodes_i): Add alloc alias without ar.pfs as first input. Add ld16 aliases without ar.csd as second output. Add st16 aliases without ar.csd as second input. Add cmpxchg aliases without ar.ccv as third input. Add cmp8xchg16 aliases without ar.csd/ ar.ccv as third/fourth inputs. Consolidate through... (CMPXCHG_acq, CMPXCHG_rel, CMPXCHG_1, CMPXCHG_2, CMPXCHG_4, CMPXCHG_8, CMPXCHGn, CMP8XCHG16, CMPXCHG_ALL): Define. * ia64-asmtab.c: Regenerate.
