* Fix PPC64 CR spill location for callee-saved registersHal Finkel2013-04-151-19/+10
| | | | | | | | | | | | | | | | 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 Majnemer2013-04-143-5/+17
| | | | | | | | | | | | | | | | | | | | | | | 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

* Fix a scalability issue with complex ConstantExprs.Benjamin Kramer2013-04-131-0/+97
| | | | | | | | | | | | | | | This is basically the same fix in three different places. We use a set to avoid walking the whole tree of a big ConstantExprs multiple times. For example: (select cmp, (add big_expr 1), (add big_expr 2)) We don't want to visit big_expr twice here, it may consist of thousands of nodes. The testcase exercises this by creating an insanely large ConstantExprs out of a loop. It's questionable if the optimizer should ever create those, but this can be triggered with real C code. Fixes PR15714. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179458 91177308-0d34-0410-b5e6-96231b3b80d8
* Spill and restore PPC CR registers using the FP when we have oneHal Finkel2013-04-131-1/+14
| | | | | | | | | | For functions that need to spill CRs, and have dynamic stack allocations, the value of the SP during the restore is not what it was during the save, and so we need to use the FP in these cases (as for all of the other spills and restores, but the CR restore has a special code path because its reserved slot, like the link register, is specified directly relative to the adjusted SP). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179457 91177308-0d34-0410-b5e6-96231b3b80d8

* MI-Sched: schedule physreg copies.Andrew Trick2013-04-131-0/+48
| | | | | | | | | | | The register allocator expects minimal physreg live ranges. Schedule physreg copies accordingly. This is slightly tricky when they occur in the middle of the scheduling region. For now, this is handled by rescheduling the copy when its associated instruction is scheduled. Eventually we may instead bundle them, but only if we can preserve the bundles as parallel copies during regalloc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179449 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: Correct printing of pre-indexed operands.Quentin Colombet2013-04-122-1/+43
| | | | | | | | | | | | | | According to the ARM reference manual, constant offsets are mandatory for pre-indexed addressing modes. The MC disassembler was not obeying this when the offset is 0. It was producing instructions like: str r0, [r1]!. Correct syntax is: str r0, [r1, #0]!. This change modifies the dumping of operands so that the offset is always printed, regardless of its value, when pre-indexed addressing mode is used.
