Chris Lattner	4f87f1c087	Treat clobber operands like early clobbers: if we have ... any, we force sdisel to do all regalloc for an asm. This leads to gross but correct codegen. This fixes the rest of PR2078. llvm-svn: 47454	2008-02-21 19:43:13 +00:00
Chris Lattner	99b5a37d39	Fix a (harmless) but where vregs were added to the used reg lists for ... inline asms. Fix PR2078 by marking aliases of registers used when a register is marked used. This prevents EAX from being allocated when AX is listed in the clobber set for the asm. llvm-svn: 47426	2008-02-21 04:55:52 +00:00
