* Appease a gcc warning about an overflow in a constant conversion.Bill Wendling2013-04-171-1/+2

* Don't store AttributeSet::FunctionIndex as an int.Benjamin Kramer2013-04-171-1/+1
| | | | | | | | GCC complains: Core.cpp:1449:27: warning: overflow in implicit constant conversion [-Woverflow] I'm not sure if that's really a problem here, but using the enum type is better style anyways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179696 91177308-0d34-0410-b5e6-96231b3b80d8

* Mark all PPC comparison instructions as not having side effectsHal Finkel2013-04-152-20/+28
| | | | | | | | | | Now that the CR spilling issues have been resolved, we can remove the unmodeled-side-effect attributes from the comparison instructions (and also mark them as isCompare). By allowing these, by default, to have unmodeled side effects, we were hiding problems with CR spilling; but everything seems much happier now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179502 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix PPC64 CR spill location for callee-saved registersHal Finkel2013-04-152-35/+50
| | | | | | | | | | | | | | | | This fixes an ABI bug for non-Darwin PPC64. For the callee-saved condition registers, the spill location is specified relative to the stack pointer (SP + 8). However, this is not relative to the SP after the new stack frame is established, but instead relative to the caller's stack pointer (it is stored into the linkage area of the parent's stack frame). So, like with the link register, we don't directly spill the CRs with other callee-saved registers, but just mark them to be spilled during prologue generation. In practice, this reverts r179457 for PPC64 (but leaves it in place for PPC32). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179500 91177308-0d34-0410-b5e6-96231b3b80d8

* Reorders two transforms that collide with each otherDavid Majnemer2013-04-141-8/+8
| | | | | | | | | | | | | | | | | | | | | | | One performs: (X == 13 | X == 14) -> X-13 <u 2 The other: (A == C1 || A == C2) -> (A & ~(C1 ^ C2)) == C1 The problem is that there are certain values of C1 and C2 that trigger both transforms but the first one blocks out the second, this generates suboptimal code. Reordering the transforms should be better in every case and allows us to do interesting stuff like turn: %shr = lshr i32 %X, 4 %and = and i32 %shr, 15 %add = add i32 %and, -14 %tobool = icmp ne i32 %add, 0 into: %and = and i32 %X, 240 %tobool = icmp ne i32 %and, 224 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179493 91177308-0d34-0410-b5e6-96231b3b80d8
