* [fast-isel] Add support for UDIV.Chad Rosier2012-02-031-8/+10

* ArrayRef'ize MI::setPhysRegsDeadExcept().Jakob Stoklund Olesen2012-02-032-4/+5

* Handle all live physreg defs in the same place.Jakob Stoklund Olesen2012-02-032-44/+47
| | | | | | | | | | | SelectionDAG has 4 different ways of passing physreg defs to users. Collect all of the uses at the same time, and pass all of them to MI->setPhysRegsDeadExcept() to mark the remaining defs dead. The setPhysRegsDeadExcept() function will soon add the required implicit-defs to instructions with register mask operands. llvm-svn: 149708
* [fast-isel] Add support for FPToUI. Also add test cases for FPToSI.Chad Rosier2012-02-032-6/+60

* The type-legalizer often scalarizes code. One of the common patterns is ↵Nadav Rotem2012-02-033-1/+43
| | | | | | | | | extract-and-truncate. In this patch we optimize this pattern and convert the sequence into extract op of a narrow type. This allows the BUILD_VECTOR dag optimizations to construct efficient shuffle operations in many cases. llvm-svn: 149692

| | | | llvm-svn: 149678
* Do the same fix as r149667, but for the Mach-O disassembler.Cameron Zwarich2012-02-031-0/+4
| | | | llvm-svn: 149674
* Added TargetPassConfig. The first little step toward configuring codegen passes.Andrew Trick2012-02-0325-268/+565
| | | | | | | | | | | Allows command line overrides to be centralized in LLVMTargetMachine.cpp. LLVMTargetMachine can intercept common passes and give precedence to command line overrides. Allows adding "internal" target configuration options without touching TargetOptions. Encapsulates the PassManager. Provides a good point to initialize all CodeGen passes so that Pass ID's can be used in APIs. Allows modifying the target configuration hooks without rebuilding the world. llvm-svn: 149672

| | | | | | | | needed to emit a 64-bit gp-relative relocation entry. Make changes necessary for emitting jump tables which have entries with directive .gpdword. This patch does not implement the parts needed for direct object emission or JIT. llvm-svn: 149668

| | | | | | | dylib. This regressed with r145408. I will try to make a test case and add it so that this doesn't happen again. llvm-svn: 149667
* Incorporate suggestions Chad, Jakob and Evan's suggestions on r149957.Lang Hames2012-02-031-22/+33

* Fix SSAUpdaterImpl's RecordMatchingPHI to record exactly theDan Gohman2012-02-032-32/+88
| | | | | | | | | | PHI nodes which were matched, rather than climbing up the original PHI node's operands to rediscover PHI nodes for recording, since the PHI nodes found that are not necessarily part of the matched set. This fixes rdar://10589171. llvm-svn: 149654

* Require non-NULL register masks.Jakob Stoklund Olesen2012-02-026-15/+12
| | | | | | | It doesn't seem worthwhile to give meaning to a NULL register mask pointer. It complicates all the code using register mask operands. llvm-svn: 149646
* build/make: Ensure make clean removes the LLVMBuild makefile fragment.Daniel Dunbar2012-02-021-0/+4

* Add pseudo-registers for pairs, triples, and quads of D registers.Jakob Stoklund Olesen2012-02-021-15/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | NEON loads and stores accept single and double spaced pairs, triples, and quads of D registers. This patch adds new register classes to accurately model those constraints: Dn, Dn+1 Dn, Dn+2 ---------------------- DPair DPairSpc DTriple DTripleSpc DQuad DQuadSpc Also extend the existing QQ and QQQQ register classes to contains all Q pairs and quads instead of just the aligned ones. These new register classes will make it possible to accurately model constraints on NEON loads and stores, and we can get rid of all the NEON pseudo-instructions. The late scheduler will be able to accurately model instruction dependencies from the explicit operands. This more than doubles the number of ARM registers, but the backend passes are quite good at handling this. The llc -O0 compile time only regresses by 1.5%. Future work on register mask operands will recover this regression. llvm-svn: 149640

* Minor changes from review.Hal Finkel2012-02-021-19/+17
| | | | | | As suggested by Nick Lewycky, the tree traversal queues have been changed to SmallVectors and the associated loops have been rotated. Also, an 80-col violation was fixed. llvm-svn: 149607

* Vectorize long blocks in groups.Hal Finkel2012-02-021-41/+90
| | | | | | Long basic blocks with many candidate pairs (such as in the SHA implementation in Perl 5.14; thanks to Roman Divacky for the example) used to take an unacceptably-long time to compile. Instead, break long blocks into groups so that no group has too many candidate pairs. llvm-svn: 149595
