Jakob Stoklund Olesen e4f273908b Freeze the reserved registers as soon as isel is complete. ... Also provide an MRI::getReservedRegs() function to access the frozen register set, and isReserved() and isAllocatable() methods to test individual registers. The various implementations of TRI::getReservedRegs() are quite complicated, and many passes need to look at the reserved register set. This patch makes it possible for these passes to use the cached copy in MRI, avoiding a lot of malloc traffic and repeated calculations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165982 91177308-0d34-0410-b5e6-96231b3b80d8		2012-10-15 21:33:06 +00:00
