Justin Holewinski	3021ef095b	[NVPTX] Improve handling of FP fusion ... We now consider the FPOpFusion flag when determining whether to fuse ops. We also explicitly emit add.rn when fusion is disabled to prevent ptxas from fusing the operations on its own. llvm-svn: 213287	2014-07-17 18:10:09 +00:00
Justin Holewinski	f7d6ae0d5b	Make AsmPrinter::emitImplicitDef a virtual method so targets can emit custom comments for implicit defs ... For NVPTX, this fixes a crash where the emitImplicitDef implementation was expecting physical registers, while NVPTX uses virtual registers (with a couple of exceptions). Now, the implicit def comment will be emitted as a true PTX register name. Other targets can use this to customize the output of implicit def comments.
