switch this to use fastcc to avoid fpstack traffic on x86-32. Switch to using the count script instead of wc -l git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41072 91177308-0d34-0410-b5e6-96231b3b80d8 2007-08-14 16:14:10 +00:00			`; RUN: llvm-as < %s \| llc -march=x86-64 \| grep LCPI \| count 3`

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40736 91177308-0d34-0410-b5e6-96231b3b80d8 2007-08-02 14:27:55 +00:00
