Chris Lattner 63079f0757 Fold comparisons against a constant nan, and optimize ORD/UNORD ... comparisons with a constant. This allows us to compile isnan to: _foo: fcmpu cr7, f1, f1 mfcr r2 rlwinm r3, r2, 0, 31, 31 blr instead of: LCPI1_0: ; float .space 4 _foo: lis r2, ha16(LCPI1_0) lfs f0, lo16(LCPI1_0)(r2) fcmpu cr7, f1, f0 mfcr r2 rlwinm r3, r2, 0, 31, 31 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45405 91177308-0d34-0410-b5e6-96231b3b80d8		2007-12-29 08:37:08 +00:00
