Akira Hatanaka 306030f8aa [X86] Simplify X87 stackifier pass. ... Stop using ST registers for function returns and inline-asm instructions and use FP registers instead. This allows removing a large amount of code in the stackifier pass that was needed to track register liveness and handle copies between ST and FP registers and function calls returning floating point values. It also fixes a bug which manifests when an ST register defined by an inline-asm instruction was live across another inline-asm instruction, as shown in the following sequence of machine instructions: 1. INLINEASM <es:frndint> $0:[regdef], %ST0<imp-def,tied5> 2. INLINEASM <es:fldcw $0> 3. %FP0<def> = COPY %ST0 <rdar://problem/16952634> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214580 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-01 22:19:41 +00:00
