2013-04-14Add support for the abs64 SPARC v9 code model.Jakob Stoklund Olesen

2013-04-14Add support for the SPARC v9 abs44 code model.Jakob Stoklund Olesen
This is the default model for non-PIC 64-bit code. It supports text+data+bss linked anywhere in the low 16 TB of the address space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179473 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-14Use target flags for printing SPARC asm operands.Jakob Stoklund Olesen
64-bit code models need multiple relocations that can't be inferred from the opcode like they can in 32-bit code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179472 91177308-0d34-0410-b5e6-96231b3b80d8

Constant pool entries are accessed exactly the same way as global variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179471 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-14SLPVectorizer: add initial support for reduction variable vectorization.Nadav Rotem

2013-04-14Fix patterns for 64-bit pointers.Jakob Stoklund Olesen
This fixes the pic32 code model for SPARC v9. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179469 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-14Add target flags to SPARC address operands.Jakob Stoklund Olesen
SDNodes and MachineOperands get target flags representing the %hi() and %lo() assembly annotations that eventually become relocations. Also define flags to be used by the 64-bit code models. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179468 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-13Mark all PPC CR registers to be spilled as live-in and tag MFCR appropriatelyHal Finkel
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
2013-04-13Define SPARC code models.Jakob Stoklund Olesen
Currently, only abs32 and pic32 are implemented. Add a test case for abs32 with 64-bit code. 64-bit PIC code is currently broken. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179463 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-13Use the correct types when matching ADDRri patterns from frame indexes.Jakob Stoklund Olesen
It doesn't seem like anybody is checking types this late in isel, so no test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179462 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-13GlobalDCE: Fix an oversight in my last commit that could lead to crashes.Benjamin Kramer
There is a Constant with non-constant operands: blockaddress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179460 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-13Fix a scalability issue with complex ConstantExprs.Benjamin Kramer
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
2013-04-13Spill and restore PPC CR registers using the FP when we have oneHal Finkel
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
2013-04-13Further generalize this scheduler test.Andrew Trick
The order of copies depends on queue order, which is not very stable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179456 91177308-0d34-0410-b5e6-96231b3b80d8

to check for a variant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179451 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-13X86 machine model: reduce SandyBridge and Haswell ILPWindow.Andrew Trick
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
2013-04-13MI-Sched: schedule physreg copies.Andrew Trick
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
2013-04-13Catch another case where SD fails to propagate node order.Andrew Trick
I need to handle this for the test case in my following scheduler commit. Work is already under way to redesign the mechanism for node order propagation because this case by case approach is unmaintainable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179448 91177308-0d34-0410-b5e6-96231b3b80d8
