* Add target flags to SPARC address operands.Jakob Stoklund Olesen2013-04-143-14/+95
| | | | | | | | | SDNodes and MachineOperands get target flags representing the %hi() and %lo() assembly annotations that eventually become relocations.

* Mark all PPC CR registers to be spilled as live-in and tag MFCR appropriatelyHal Finkel2013-04-133-15/+16
| | | | | | | | | | | | Leaving MFCR has having unmodeled side effects is not enough to prevent unwanted instruction reordering post-RA. We could probably apply a stronger barrier attribute, but there is a better way: Add all (not just the first) CR to be spilled as live-in to the entry block, and add all CRs to the MFCR instruction as implicitly killed. Unfortunately, I don't have a small test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179465 91177308-0d34-0410-b5e6-96231b3b80d8

* GlobalDCE: Fix an oversight in my last commit that could lead to crashes.Benjamin Kramer2013-04-131-2/+2

* Fix a scalability issue with complex ConstantExprs.Benjamin Kramer2013-04-133-25/+52
| | | | | | | | | | | | | | | 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 Finkel2013-04-131-6/+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

* X86 machine model: reduce SandyBridge and Haswell ILPWindow.Andrew Trick2013-04-132-2/+2
| | | | | | | | | | | | | | | The initial values were arbitrary. I want them to be more conservative. This represents the number of latency cycles hidden by OOO execution. In practice, I think it should be within a small factor of the complex floating point operation latency so the scheduler can make some attempt to hide latency even for smallish blocks. These are by no means the best values, just a starting point for tuning heuristics. Some benchmarks such as TSVC run faster with this lower value for SandyBridge. I haven't run anything on Haswell, but it's shouldn't be 2x SB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179450 91177308-0d34-0410-b5e6-96231b3b80d8
* MI-Sched: schedule physreg copies.Andrew Trick2013-04-132-1/+76
| | | | | | | | | | | 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 Colombet2013-04-124-26/+57
| | | | | | | | | | | | | | 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.

* PPC: Remove (broken) nested implicit definition listsHal Finkel2013-04-122-94/+153
| | | | | | | | | | TableGen will not combine nested list 'let' bindings into a single list, and instead uses only the inner scope. As a result, several instruction definitions were missing implicit register defs that were in outer scopes. This de-nests these scopes and makes all instructions have only one let binding which sets implicit register definitions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179392 91177308-0d34-0410-b5e6-96231b3b80d8
