* LoopVectorizer: Change variable name Stride to ConsecutiveStrideArnold Schwaighofer2013-04-241-6/+6
| | | | | | | | This makes it easier to read the code. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180197 91177308-0d34-0410-b5e6-96231b3b80d8
* LoopVectorize: Scalarize padded typesArnold Schwaighofer2013-04-242-1/+38
| | | | | | | | | | | | | | | | | | This patch disables memory-instruction vectorization for types that need padding bytes, e.g., x86_fp80 has 10 bytes store size with 6 bytes padding in darwin on x86_64. Because the load/store vectorization is performed by the bit casting to a packed vector, which has incompatible memory layout due to the lack of padding bytes, the present vectorizer produces inconsistent result for memory instructions of those types. This patch checks an equality of the AllocSize of a scalar type and allocated size for each vector element, to ensure that there is no padding bytes and the array can be read/written using vector operations. Patch by Daisuke Takahashi! Fixes PR15758. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180196 91177308-0d34-0410-b5e6-96231b3b80d8

* MI Sched: eliminate local vreg copies.Andrew Trick2013-04-246-10/+242
| | | | | | | | | | | | | | | | For now, we just reschedule instructions that use the copied vregs and let regalloc elliminate it. I would really like to eliminate the copies on-the-fly during scheduling, but we need a complete implementation of repairIntervalsInRange() first. The general strategy is for the register coalescer to eliminate as many global copies as possible and shrink live ranges to be extended-basic-block local. The coalescer should not have to worry about resolving local copies (e.g. it shouldn't attemp to reorder instructions). The scheduler is a much better place to deal with local interference. The coalescer side of this equation needs work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180193 91177308-0d34-0410-b5e6-96231b3b80d8
* Register Coalescing: add a flag to disable rescheduling.Andrew Trick2013-04-241-2/+8
| | | | | | | | When MachineScheduler is enabled, this functionality can be removed. Until then, provide a way to disable it for test cases and designing MachineScheduler heuristics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180192 91177308-0d34-0410-b5e6-96231b3b80d8

* Use a pointer as the relocation iterator.Rafael Espindola2013-04-241-23/+28
| | | | | | | | Since the relocation iterator walks only the relocations in one section, we can just use a pointer and avoid fetching information about the section at every reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180189 91177308-0d34-0410-b5e6-96231b3b80d8

* Machine model: Generate table entries for super-resources.Andrew Trick2013-04-231-14/+23
| | | | | | | | | Super-resources and resource groups are two ways of expressing overlapping sets of processor resources. Now we generate table entries the same way for both so the scheduler never needs to explicitly check for super-resources. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180162 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify yaml2obj a bit.Rafael Espindola2013-04-231-105/+112
| | | | | | | | | | | | The COFFParser now contains only a COFFYAML::Object and the string table (which is recomputed, not serialized). The structs in COFFParser now all begin with a Header field with what is actually on the COFF object. The other fields are things that are semantically part of the struct (relocations in a section for exmaple), but are not actually represented that way in the object file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180134 91177308-0d34-0410-b5e6-96231b3b80d8
