Chris Lattner a411cbca5c Try to avoid scanning the fixed list. On architectures with a non-stupid ... number of regs (e.g. most riscs), many functions won't need to use callee clobbered registers. Do a speculative check to see if we can get a free register without processing the fixed list (which has all of these). This saves a lot of time on machines with lots of callee clobbered regs (e.g. ppc and itanium, also x86). This reduces ppc llc compile time from 184s -> 172s on kc++. This is probably worth FAR FAR more on itanium though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22972 91177308-0d34-0410-b5e6-96231b3b80d8		2005-08-22 20:59:30 +00:00
