* Fix a long standing deficiency in the X86 backend: we wouldChris Lattner2007-11-255-97/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sometimes emit "zero" and "all one" vectors multiple times, for example: _test2: pcmpeqd %mm0, %mm0 movq %mm0, _M1 pcmpeqd %mm0, %mm0 movq %mm0, _M2 ret instead of: _test2: pcmpeqd %mm0, %mm0 movq %mm0, _M1 movq %mm0, _M2 ret This patch fixes this by always arranging for zero/one vectors to be defined as v4i32 or v2i32 (SSE/MMX) instead of letting them be any random type. This ensures they get trivially CSE'd on the dag. This fix is also important for LegalizeDAGTypes, as it gets unhappy when the x86 backend wants BUILD_VECTOR(i64 0) to be legal even when 'i64' isn't legal. This patch makes the following changes: 1) X86TargetLowering::LowerBUILD_VECTOR now lowers 0/1 vectors into their canonical types. 2) The now-dead patterns are removed from the SSE/MMX .td files. 3) All the patterns in the .td file that referred to immAllOnesV or immAllZerosV in the wrong form now use *_bc to match them with a bitcast wrapped around them. 4) X86DAGToDAGISel::SelectScalarSSELoad is generalized to handle bitcast'd zero vectors, which simplifies the code actually. 5) getShuffleVectorZeroOrUndef is updated to generate a shuffle that is legal, instead of generating one that is illegal and expecting a later legalize pass to clean it up. 6) isZeroShuffle is generalized to handle bitcast of zeros. 7) several other minor tweaks. This patch is definite goodness, but has the potential to cause random code quality regressions. Please be on the lookout for these and let me know if they happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44310 91177308-0d34-0410-b5e6-96231b3b80d8

* Several changes:Chris Lattner2007-11-248-149/+277
| | | | | | | | | | | | | | | | | | | | | | | 1) Change the interface to TargetLowering::ExpandOperationResult to take and return entire NODES that need a result expanded, not just the value. This allows us to handle things like READCYCLECOUNTER, which returns two values. 2) Implement (extremely limited) support in LegalizeDAG::ExpandOp for MERGE_VALUES. 3) Reimplement custom lowering in LegalizeDAGTypes in terms of the new ExpandOperationResult. This makes the result simpler and fully general. 4) Implement (fully general) expand support for MERGE_VALUES in LegalizeDAGTypes. 5) Implement ExpandOperationResult support for ARM f64->i64 bitconvert and ARM i64 shifts, allowing them to work with LegalizeDAGTypes. 6) Implement ExpandOperationResult support for X86 READCYCLECOUNTER and FP_TO_SINT, allowing them to work with LegalizeDAGTypes. LegalizeDAGTypes now passes several more X86 codegen tests when enabled and when type legalization in LegalizeDAG is ifdef'd out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44300 91177308-0d34-0410-b5e6-96231b3b80d8

There was a problem with use of strtoll in TGLexer.cpp and Chris suggested switching to strtol, so that's included here. Additionally, this checkin adds minimal x64 builds to the VStudio builds. Build issues related to x64 in the windows specific files for DynamicLibrary.inc and Singals.inc are worked around, but not ultimately solved. Binaries used to be stored in ...\win32\{Debug|Release} but are now kept in ...\win32\bin\{win32|x64}\{Debug|Release} intermediate files will continue to be stored in the individual project directories under win32. Some names will likely change in the future to reflect that the vstudio projects are no longer 32-bit only, but I wanted to get things up and running today so kept away from bigger restructuring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44260 91177308-0d34-0410-b5e6-96231b3b80d8
