Jakob Stoklund Olesen d9e5c764bf Freeze reserved registers before starting register allocation. ... The register allocators don't currently support adding reserved registers while they are running. Extend the MRI API to keep track of the set of reserved registers when register allocation started. Target hooks like hasFP() and needsStackRealignment() can look at this set to avoid reserving more registers during register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147577 91177308-0d34-0410-b5e6-96231b3b80d8		2012-01-05 00:26:49 +00:00
