Andrew Trick 19273aec44 Clear virtual registers after they are no longer referenced. ... Passes after RegAlloc should be able to rely on MRI->getNumVirtRegs() == 0. This makes sharing code for pre/postRA passes more robust. Now, to check if a pass is running before the RA pipeline begins, use MRI->isSSA(). To check if a pass is running after the RA pipeline ends, use !MRI->getNumVirtRegs(). PEI resets virtual regs when it's done scavenging. PTX will either have to provide its own PEI pass or assign physregs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151032 91177308-0d34-0410-b5e6-96231b3b80d8		2012-02-21 04:51:23 +00:00
