This patch changes the X86 back end to use the new subreg operations for appropriate truncate and extend operations. This should allow regression testing of the subreg feature going forward, as it's now used in a public target.The patch passed DejaGnu and all of SingleSource on my x86 machine, but
Very cool! I need to read it more carefully. But I see you are
lowering zext to a single insert_subreg. Is that right? It won't zero
out the top part, no?

2. Properly initialize LLVM machinery, when PCHs are used

It's only lowering (zext i32 to i64) to an insert_subreg on x86-64

Change the x86 backend to use extract_subreg for truncation operations. Passes
DejaGnu, SingleSource and MultiSource.
Modified:

This patch causes anyext and zext to be code generated as insert_subreg on x86-64. It passes all tests on my system, but my system isn't x86-64. If someone would give it a run that'd be appreciated.Thanks --Christopher Lamb
