Jakob Stoklund Olesen b712ef9569 Allocate SystemZ callee-saved registers backwards: R13-R6 ... The reserved R14-R15 are always saved in the prolog, and using CSRs starting from R13 allows them to be saved in one instruction. Thanks to Anton for explaining this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133233 91177308-0d34-0410-b5e6-96231b3b80d8		2011-06-17 03:47:30 +00:00
