Benjamin Kramer 1fdfae05b0 InstCombine: Canonicalize (2^n)-1 - x into (2^n)-1 ^ x iff x is known to be smaller than 2^n. ... This has the obvious advantage of being commutable and is always a win on x86 because const - x wastes a register there. On less weird architectures this may lead to a regression because other arithmetic doesn't fuse with it anymore. I'll address that problem in a followup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147254 91177308-0d34-0410-b5e6-96231b3b80d8		2011-12-24 17:31:38 +00:00
