[llvm-commits] [PATCH] Fix fastcc structure return with fast-isel on x86-32

[Derek Schuff]

Hi all,
on x86-32, structure return via sret lets the callee pop the hidden
pointer argument off the stack, which the caller then re-pushes.
However if the calling convention is fastcc, then a register is used
instead, and the caller should not adjust the stack. This is
implemented with a check of IsTailCallConvention
X86TargetLowering::LowerCall  but is not checked properly in
X86FastISel::DoSelectCall. The attached patch fixes that. Please
review.
thanks,
-Derek
