switch this to use fastcc to avoid fpstack traffic on x86-32. Switch to using the count script instead of wc -l llvm-svn: 41072 2007-08-14 18:14:10 +02:00			`; RUN: llvm-as < %s \| llc -march=x86-64 \| grep LCPI \| count 3`
Added support to fold X86 load / store instructions. This allow rematerialized loads to be folded into their uses. llvm-svn: 41599 2007-08-30 07:54:07 +02:00			`; RUN: llvm-as < %s \| llc -march=x86-64 -stats -info-output-file - \| grep asm-printer \| grep 6`

Mark the SSE and MMX load instructions that X86InstrInfo::isReallyTriviallyReMaterializable knows how to handle with the isReMaterializable flag so that it is given a chance to handle them. Without hoisting constant-pool loads from loops this isn't very visible, though it does keep CodeGen/X86/constant-pool-remat-0.ll from making a copy of the constant pool on the stack. llvm-svn: 40736 2007-08-02 16:27:55 +02:00
