Nate Begeman 1cbf3abbb8 Next round of PPC CR optimizations. For the following code: ... int %bar(float %a, float %b, float %c, float %d) { entry: %tmp.1 = setlt float %a, %d %tmp.2 = setlt float %b, %d %or = or bool %tmp.1, %tmp.2 %tmp.3 = setgt float %c, %d %tmp.4 = or bool %or, %tmp.3 %tmp.5 = and bool %tmp.4, true %retval = cast bool %tmp.5 to int ret int %retval } We now emit: _bar: .LBB_bar_0: ; entry fcmpu cr0, f1, f4 fcmpu cr1, f2, f4 cror 0, 0, 4 fcmpu cr1, f3, f4 cror 28, 0, 5 mfcr r2 rlwinm r3, r2, 29, 31, 31 blr Instead of: _bar: .LBB_bar_0: ; entry fcmpu cr7, f1, f4 mfcr r2 rlwinm r2, r2, 29, 31, 31 fcmpu cr7, f2, f4 mfcr r3 rlwinm r3, r3, 29, 31, 31 or r2, r2, r3 fcmpu cr7, f3, f4 mfcr r3 rlwinm r3, r3, 30, 31, 31 or r3, r2, r3 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21321 91177308-0d34-0410-b5e6-96231b3b80d8		2005-04-18 07:48:09 +00:00
