2007-04-28memory operands that have a direct operand should have their stores createdChris Lattner
before the copies into physregs are done. This avoids having flag operands skip the store, causing cycles in the dag at sched time. This fixes infinite loops on these tests: test/CodeGen/Generic/2007-04-08-MultipleFrameIndices.ll for PR1308 test/CodeGen/PowerPC/2007-01-29-lbrx-asm.ll test/CodeGen/PowerPC/2007-01-31-InlineAsmAddrMode.ll test/CodeGen/X86/2006-07-12-InlineAsmQConstraint.ll for PR828 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36547 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-12the result of an inline asm copy can be an arbitrary VT that the registerChris Lattner
class supports. In the case of vectors, this means we often get the wrong type (e.g. we get v4f32 instead of v8i16). Make sure to convert the vector result to the right type.
