* The DIBuilder class is just a wrapper around debug info creationBill Wendling2012-06-298-9/+9
| | | | | | | (a.k.a. MDNodes). The module doesn't belong in Analysis. Move it to the VMCore instead. llvm-svn: 159414
* Revert "Make NumMicroOps a variable in the subtarget's instruction itinerary."Andrew Trick2012-06-299-79/+62
| | | | | | This reverts commit r159406. I noticed a performance regression so I'll back out for now. llvm-svn: 159411
* In the initial exec mode we always do a load to find the address of a variable.Rafael Espindola2012-06-292-9/+10
| | | | | | | | | Before this patch in pic 32 bit code we would add the global base register and not load from that address. This is a really old bug, but before the introduction of the tls attributes we would never select initial exec for pic code. llvm-svn: 159409
* misched: avoid scheduling instructions that can't be dispatched.Andrew Trick2012-06-291-6/+29

* Make NumMicroOps a variable in the subtarget's instruction itinerary.Andrew Trick2012-06-299-63/+81
| | | | | | | | | | | | | | The TargetInstrInfo::getNumMicroOps API does not change, but soon it will be used by MachineScheduler. Now each subtarget can specify the number of micro-ops per itinerary class. For ARM, this is currently always dynamic (-1), because it is used for load/store multiple which depends on the number of register operands. Zero is now a valid number of micro-ops. This can be used for nop pseudo-instructions or instructions that the hardware can squash during dispatch. llvm-svn: 159406
* X86: add more GATHER intrinsics in LLVMManman Ren2012-06-298-39/+231
| | | | | | | | | | | | | | | Corrected type for index of llvm.x86.avx2.gather.d.pd.256 from 256-bit to 128-bit. Corrected types for src|dst|mask of llvm.x86.avx2.gather.q.ps.256 from 256-bit to 128-bit. Support the following intrinsics: llvm.x86.avx2.gather.d.q, llvm.x86.avx2.gather.q.q llvm.x86.avx2.gather.d.q.256, llvm.x86.avx2.gather.q.q.256 llvm.x86.avx2.gather.d.d, llvm.x86.avx2.gather.q.d llvm.x86.avx2.gather.d.d.256, llvm.x86.avx2.gather.q.d.256 llvm-svn: 159402
* Remove a completely unnecessary mkdir from the CMake build.Chandler Carruth2012-06-291-2/+0
| | | | | | Clang has been getting along fine without this for quite some time. llvm-svn: 159400

* 'Promote' vector [su]int_to_fp should widen elements.Jim Grosbach2012-06-281-3/+54
| | | | | | | | | | | Teach vector legalization how to honor Promote for int to float conversions. The code checking whether to promote the operation knew to look at the operand, but the actual promotion code didn't. This fixes that. The operand is promoted up via [zs]ext. rdar://11762659 llvm-svn: 159378

* Precompute SCEV pointer analysis prior to instruction fusion in BBVectorize.Hal Finkel2012-06-281-10/+51
| | | | | | | | | | | | | When both a load/store and its address computation are being vectorized, it can happen that the address-computation vectorization destroys SCEV's ability to analyize the relative pointer offsets. As a result (like with the aliasing analysis info), we need to precompute the necessary information prior to instruction fusing. This was found during stress testing (running through the test suite with a very low required chain length); unfortunately, I don't have a small test case. llvm-svn: 159332
* Remove a useless check in BBVectorize.Hal Finkel2012-06-281-5/+0
| | | | | | | A shuffle mask will always be a constant, but I did not realize that when I originally wrote the code. llvm-svn: 159331
* Allow BBVectorize to form non-2^n-length vectors.Hal Finkel2012-06-284-134/+571
| | | | | | | | | | | | | | | | | | | | The original algorithm only used recursive pair fusion of equal-length types. This is now extended to allow pairing of any types that share the same underlying scalar type. Because we would still generally prefer the 2^n-length types, those are formed first. Then a second set of iterations form the non-2^n-length types. Also, a call to SimplifyInstructionsInBlock has been added after each pairing iteration. This takes care of DCE (and a few other things) that make the following iterations execute somewhat faster. For the same reason, some of the simple shuffle-combination cases are now handled internally. There is some additional refactoring work to be done, but I've had many requests for this feature, so additional refactoring will come soon in future commits (as will additional test cases). llvm-svn: 159330
* Refactor operation equivalence checking in BBVectorize by extending ↵Hal Finkel2012-06-283-29/+29
| | | | | | | | | | | Instruction::isSameOperationAs. Maintaining this kind of checking in different places is dangerous, extending Instruction::isSameOperationAs consolidates this logic into one place. Here I've added an optional flags parameter and two flags that are important for vectorization: CompareIgnoringAlignment and CompareUsingScalarTypes. llvm-svn: 159329

* Remove 'site.exp' building from both CMake and configure+make.Chandler Carruth2012-06-285-62/+14
| | | | | | | | | | | This is another vestige of the DejaGNU roots. There were FIXMEs in the lit setup to add a 'lit.site.cfg', which has been around for quite some time now, so I've properly switched the handling of the 4 things actually used in site.exp to go through lit.site.cfg now. No more parsing of the .exp file, one fewer configure-style generated file, etc., etc. llvm-svn: 159313
* Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp andBill Wendling2012-06-2842-108/+106
| | | | | | | | | include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h. The reasoning is because the DebugInfo module is simply an interface to the debug info MDNodes and has nothing to do with analysis. llvm-svn: 159312
