Jakob Stoklund Olesen 448ab3ab39 Avoid calling TRI->getAllocatableSet in RAFast. ... When compiling a program with lots of small functions like 483.xalancbmk, this makes RAFast 11% faster. Add some comments to clarify the difference between unallocatable and reserved registers. It's quite subtle. The fast register allocator depends on EFLAGS' not being allocatable on x86. That way it can completely avoid tracking liveness, and it won't mind when there are multiple uses of a single def. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132514 91177308-0d34-0410-b5e6-96231b3b80d8		2011-06-02 23:41:40 +00:00

Analysis	When marking a block as being unanalyzable, use "Clobber" on the terminator instead of the first instruction in the block. This is a bit of a hack; "Clobber" isn't really the right marking in the first place. memdep doesn't really have any way of properly expressing "unanalyzable" at the moment. Using it on the terminator is much less ambiguous than using it on an arbitrary instruction, though.	2011-06-02 00:08:52 +00:00
