* LegalizeDAG is not supposed to introduce illegalDuncan Sands2008-12-131-2/+2
| | | | | | | types into the DAG if they were not already there. Check this with an assertion. llvm-svn: 60997
* If the type legalizer actually legalized anythingDuncan Sands2008-11-241-8/+29
| | | | | | | | | | | | | (this doesn't happen that often, since most code does not use illegal types) then follow it by a DAG combiner run that is allowed to generate illegal operations but not illegal types. I didn't modify the target combiner code to distinguish like this between illegal operations and illegal types, so it will not produce illegal operations as well as not producing illegal types. llvm-svn: 59960
* Remove the "fast" form of the list-burr scheduler, and use theDan Gohman2008-11-201-6/+6
| | | | | | | | | dedicated "fast" scheduler in -fast mode instead, which is faster. This speeds up llc -fast by a few percent on some testcases -- the speedup only happens for code not handled by fast-isel. llvm-svn: 59700
* Experimental post-pass scheduling support. Post-pass schedulingDan Gohman2008-11-191-1/+1
| | | | | | | | | | | | | | | | | is currently off by default, and can be enabled with -disable-post-RA-scheduler=false. This doesn't have a significant impact on most code yet because it doesn't yet do anything to address anti-dependencies and it doesn't attempt to disambiguate memory references. Also, several popular targets don't have pipeline descriptions yet. The majority of the changes here are splitting the SelectionDAG-specific code out of ScheduleDAG, so that ScheduleDAG can be moved to libLLVMCodeGen.a. The interface between ScheduleDAG-using code and the rest of the scheduling code is somewhat rough and will evolve. llvm-svn: 59676
* Move the code that inserts X87 FP_REG_KILL instructions from aDan Gohman2008-11-121-3/+0
| | | | | | | | special-purpose hook to a new pass. Also, add check to see if any x87 virtual registers are used, to avoid doing any work in the common case that no x87 code is needed. llvm-svn: 59190
* Change the scheduler accessor methods to accept an explicit TargetMachineDan Gohman2008-11-111-3/+5
| | | | | | | argument instead of taking the SelectionDAG's TargetMachine. This is needed for some upcoming scheduler changes. llvm-svn: 59055
* Take Chris' suggestion and define EnableFastISelVerbose andDan Gohman2008-10-281-8/+3
| | | | | | | EnableFastISelAbort variables for Release mode instead of using ifdefs in the code. llvm-svn: 58350
* Protect the code for fast-isel debugging with #ifndef NDEBUG.Dan Gohman2008-10-281-0/+10
| | | | llvm-svn: 58340
* Turn on LegalizeTypes, the new type legalizationDuncan Sands2008-10-271-2/+2
| | | | | | | codegen infrastructure, by default. Please report any breakage to the mailing lists. llvm-svn: 58232
* Fast-isel no longer an experiment.Dan Gohman2008-10-201-1/+1
| | | | llvm-svn: 57845
* FastISel support for exception-handling constructs.Dan Gohman2008-10-141-47/+50
| | | | | | | | | - Move the EH landing-pad code and adjust it so that it works with FastISel as well as with SDISel. - Add FastISel support for @llvm.eh.exception and @llvm.eh.selector. llvm-svn: 57539
* Fix command-line option printing to print two spaces where needed,Dan Gohman2008-10-141-1/+1
| | | | | | | | | instead of requiring all "short description" strings to begin with two spaces. This makes these strings less mysterious, and it fixes some cases where short description strings mistakenly did not begin with two spaces. llvm-svn: 57521
* Fix fast-isel's handling of atomic instructions. They mayDan Gohman2008-10-041-1/+4
| | | | | | | | expand to multiple basic blocks, in which case fast-isel needs to informed of which block to use as it resumes inserting instructions. llvm-svn: 57040
* Fix FastISel to not initialize the PIC-base register multiple timesDan Gohman2008-09-291-60/+65
| | | | | | in functions with PIC references from more than one basic block. llvm-svn: 56807
* Large mechanical patch.Devang Patel2008-09-251-1/+1
| | | | | | | | | | | | | | | s/ParamAttr/Attribute/g s/PAList/AttrList/g s/FnAttributeWithIndex/AttributeWithIndex/g s/FnAttr/Attribute/g This sets the stage - to implement function notes as function attributes and - to distinguish between function attributes and return value attributes. This requires corresponding changes in llvm-gcc and clang. llvm-svn: 56622
* Don't print fast-isel debug messages by default. Thanks Chris!Dan Gohman2008-09-251-3/+6
| | | | llvm-svn: 56614
* Don't forget the newline in debug output.Dan Gohman2008-09-251-1/+1
| | | | llvm-svn: 56613
* FastISel support for debug info.Dan Gohman2008-09-251-2/+20
| | | | llvm-svn: 56610
* Enable DeadMachineInstructionElim when Fast-ISel is enabled.Dan Gohman2008-09-251-3/+0
| | | | llvm-svn: 56604
* Next round of earlyclobber handling. Approach theDale Johannesen2008-09-241-3/+2
| | | | | | | | | | RA problem by expanding the live interval of an earlyclobber def back one slot. Remove overlap-earlyclobber throughout. Remove earlyclobber bits and their handling from live internals. llvm-svn: 56539
* s/ParameterAttributes/Attributes/gDevang Patel2008-09-231-1/+0
| | | | llvm-svn: 56513
* Arrange for FastISel code to have access to the MachineModuleInfoDan Gohman2008-09-231-4/+7
| | | | | | object. This will be needed to support debug info. llvm-svn: 56508
* Add a bit to mark operands of asm's that conflictDale Johannesen2008-09-171-2/+3
| | | | | | | | | with an earlyclobber operand elsewhere. Propagate this bit and the earlyclobber bit through SDISel. Change linear-scan RA not to allocate regs in a way that conflicts with an earlyclobber. See also comments. llvm-svn: 56290
* Don't take the time to CheckDAGForTailCallsAndFixThem when tail callsDan Gohman2008-09-161-1/+2
| | | | | | | are not enabled. Instead just omit the tail call flag when calls are created. llvm-svn: 56235
* Define CallSDNode, an SDNode subclass for use with ISD::CALL.Dan Gohman2008-09-131-36/+25
| | | | | | | | | | | | | Currently it just holds the calling convention and flags for isVarArgs and isTailCall. And it has several utility methods, which eliminate magic 5+2*i and similar index computations in several places. CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle nodes that are not CSE'd gracefully. llvm-svn: 56183
* Rename ConstantSDNode::getValue to getZExtValue, for consistencyDan Gohman2008-09-121-2/+2
| | | | | | | with ConstantInt. This led to fixing a bug in TargetLowering.cpp using getValue instead of getAPIntValue. llvm-svn: 56159
* Add X86FastISel support for static allocas, and refencesDan Gohman2008-09-101-1/+2
| | | | | | | to static allocas. As part of this change, refactor the address mode code for laods and stores. llvm-svn: 56066
* Add a break statement that I accidentally deleted whenDan Gohman2008-09-101-0/+1
| | | | | | | I shuffled the fast-isel command-line options around. This fixes a bunch of fast-isel failures. llvm-svn: 56057
* Change -fast-isel-no-abort to -fast-isel-abort, which now defaultsDan Gohman2008-09-091-7/+12
| | | | | | | | to being off by default. Also, add assertion checks to check that the various fast-isel-related command-line options are only used when -fast-isel itself is enabled. llvm-svn: 56029
* Add a new option, -fast-isel-verbose, that can be used withDan Gohman2008-09-091-15/+21
| | | | | | | -fast-isel-no-abort to get a dump of all unhandled instructions, without an abort. llvm-svn: 56021
* Remove the code that protected FastISel from aborting inDan Gohman2008-09-091-5/+2
| | | | | | | | the case of loads, stores, and conditional branches. It can handle those now, so any that aren't handled should trigger the abort. llvm-svn: 55977
* Fix a few I's that were meant to be renamed to BI's.Dan Gohman2008-09-081-2/+2
| | | | llvm-svn: 55942
* Avoid redefinition and nnbreak windows build.Evan Cheng2008-09-081-16/+16
| | | | llvm-svn: 55911
* Move the code that inserts copies for function livein registersDan Gohman2008-09-051-7/+113
| | | | | | | | | out of ScheduleDAGEmit.cpp and into SelectionDAGISel.cpp. This allows it to be run exactly once per function, even if multiple SelectionDAG iterations happen in the entry block, as may happen with FastISel. llvm-svn: 55863
* Tidy up several unbeseeming casts from pointer to intptr_t.Dan Gohman2008-09-041-1/+1
| | | | llvm-svn: 55779
* Create HandlePHINodesInSuccessorBlocksFast, a version ofDan Gohman2008-09-031-32/+41
| | | | | | | | | | | | | HandlePHINodesInSuccessorBlocks that works FastISel-style. This allows PHI nodes to be updated correctly while using FastISel. This also involves some code reorganization; ValueMap and MBBMap are now members of the FastISel class, so they needn't be passed around explicitly anymore. Also, SelectInstructions is changed to SelectInstruction, and only does one instruction at a time. llvm-svn: 55746
* Split the SelectionDAG-building code, including the FunctionLoweringInfoDan Gohman2008-09-031-5134/+6
| | | | | | | and SelectionDAGLowering classes, out of SelectionDAGISel.cpp and put it in a separate file, SelectionDAGBuild.cpp. llvm-svn: 55701
* If TargetSelectInstruction returns true, move to next instruction.Evan Cheng2008-09-031-1/+3
| | | | llvm-svn: 55692
* Ensure that HandlePHINodesInSuccessorBlocks is run for all blocks,Dan Gohman2008-09-021-3/+9
| | | | | | | even in FastISel mode in the case where FastISel successfully selects all the instructions. llvm-svn: 55641
* Add a target callback for FastISel.Dan Gohman2008-08-281-2/+7
| | | | llvm-svn: 55512
* erect abstraction boundaries for accessing SDValue members, rename Val -> ↵Gabor Greif2008-08-281-30/+30
| | | | | | Node to reflect semantics llvm-svn: 55504
* Move CaseBlock, JumpTable, and BitTestBlock to be members ofDan Gohman2008-08-281-80/+77
| | | | | | | | SelectionDAGLowering instead of being in an anonymous namespace. This fixes warnings about SelectionDAGLowering having fields using anonymous namespaces. llvm-svn: 55497
* Fix a FastISel bug where the instructions from lowering the argumentsDan Gohman2008-08-281-12/+16
| | | | | | were being emitted after the first instructions of the entry block. llvm-svn: 55496
* Reduce the size of the Parts vector.Rafael Espindola2008-08-281-3/+4
| | | | llvm-svn: 55483
* Correctly resize the Parts array.Rafael Espindola2008-08-281-1/+1
