2010-02-21Eliminate some uses of immAllOnes, just use -1, it doesChris Lattner

2010-02-19Radar 7636153. In the presence of large call frames, it's not sufficientJim Grosbach
for ARM to just check if a function has a FP to determine if it's safe to simplify the stack adjustment pseudo ops prior to eliminating frame indices. Allow targets to override the default behavior and does so for ARM and Thumb2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96634 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-11refactor x86 conditional branches to use a multipatternChris Lattner
that generates the 1-byte and 4-byte immediate versions from one definition. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95902 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-10The previous fix of widening divides that trap was too fragile as it depends ↵Mon P Wang
on custom lowering and requires that certain types exist in ValueTypes.h. Modified widening to check if an op can trap and if so, the widening algorithm will apply only the op on the defined elements. It is safer to do this in widening because the optimizer can't guarantee removing unused ops in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95823 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-09move target-independent opcodes out of TargetInstrInfoChris Lattner
into TargetOpcodes.h. #include the new TargetOpcodes.h into MachineInstr. Add new inline accessors (like isPHI()) to MachineInstr, and start using them throughout the codebase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95687 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-03change addPassesToEmitFile to return true on failure instead of its input,Chris Lattner
add -filetype=null for performance testing and remove -filetype=dynlib, which isn't planned to be implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95202 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-02refactor code so that LLVMTargetMachine creates the asmstreamer and Chris Lattner
mccontext instead of having AsmPrinter do it. This allows other types of MCStreamer's to be passed in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95155 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-02Remove a bunch of stuff around the edges of the ELF writer.Chris Lattner
Now the only use of the ELF writer is the JIT, which won't be easy to fix in the short term. :( :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95148 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-02eliminate all the dead addSimpleCodeEmitter implementations.Chris Lattner
eliminate random "code emitter" stuff in Alpha, except for the JIT path. Next up, remove the template cruft. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95131 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-02eliminate FileModel::Model, just use CodeGenFileType. The clientChris Lattner
of the code generator shouldn't care what object format a target uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95124 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-02eliminate all forms of addPassesToEmitMachineCode exceptChris Lattner
the one used by the JIT. Remove all forms of addPassesToEmitFileFinish except the one used by the static code generator. Inline the remaining version of addPassesToEmitFileFinish into its only caller. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95109 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-02Inline addAssemblyEmitter into its one real caller and deleteChris Lattner
the -print-emitted-asm option. The JIT shouldn't have to pull in the asmprinter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95100 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-01Kill the Mach-O writer, and temporarily make filetype=obj an error.Nate Begeman
The MCStreamer based assemblers will take over for this functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95033 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-31Moved InstallLexer() from the X86-specific AsmLexerSean Callanan
to the TargetAsmLexer class so that clients can actually use the TargetAsmLexer they get from a Target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94940 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-27Remove a dead target hook.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94646 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-27Eliminate target hook IsEligibleForTailCallOptimization.Evan Cheng
Target independent isel should always pass along the "tail call" property. Change target hook LowerCall's parameter "isTailCall" into a refernce. If the target decides it's impossible to honor the tail call request, it should set isTailCall to false to make target independent isel happy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94626 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94532 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26eliminate the TargetLowering::UsesGlobalOffsetTable bool, which isChris Lattner
subsumed by TargetLowering::getJumpTableEncoding(). Change uses of it to be more specific. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94529 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Move getJTISymbol from MachineJumpTableInfo to MachineFunction,Chris Lattner
which is more convenient, and change getPICJumpTableRelocBaseExpr to take a MachineFunction to match. Next, move the X86 code that create a PICBase symbol to X86TargetLowering::getPICBaseSymbol from X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific library. This eliminates a 'gross hack', and allows us to implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now calls it. This in turn allows us to eliminate the X86AsmPrinter::printPICJumpTableSetLabel method, which was the only overload of printPICJumpTableSetLabel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94526 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26stub out a new target hook, need some refactoring before I canChris Lattner

2010-01-26this hook should be const.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94508 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Add support for target-specific 32-bit custom-lowered Chris Lattner
jump table entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94505 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25Rearrange handling of jump tables. Highlights:Chris Lattner
1. MachineJumpTableInfo is now created lazily for a function the first time it actually makes a jump table instead of for every function. 2. The encoding of jump table entries is now described by the MachineJumpTableInfo::JTEntryKind enum. This enum is determined by the TLI::getJumpTableEncoding() hook, instead of by lots of code scattered throughout the compiler that "knows" that jump table entries are always 32-bits in pic mode (for example). 3. The size and alignment of jump table entries is now calculated based on their kind, instead of at machinefunction creation time. Future work includes using the EntryKind in more places in the compiler, eliminating other logic that "knows" the layout of jump tables in various situations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94470 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25add a method to get the alignment of an integer type even Chris Lattner
when we don't have one laying around. Useful if you don't have an llvmcontext handy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94468 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22Filled out the skeleton of the TargetAsmLexer to behaveSean Callanan
exactly like an MCAsmLexer. (The difference is that the TargetAsmLexer knows how to handle target-specific stuff like registers, whereas the MCAsmLexer is fully generic.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94237 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-19stop using the .lcomm pseudoop on darwin, instead, directly use theChris Lattner
.zerofill directive. Streamerize its generation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93868 91177308-0d34-0410-b5e6-96231b3b80d8

duplicating the logic (differently) in lots of different targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93847 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-19Cleanup handling of .zerofill on darwin:Chris Lattner
1. TargetLoweringObjectFileMachO should decide if something goes in zerofill instead of having every target do it. 2. TargetLoweringObjectFileMachO should assign said symbols to the right MCSection, the asmprinters should just emit to the right section. 3. Since all zerofill stuff goes through mcstreamer anymore, MAI can have a bool "haszerofill" instead of having the textual directive to emit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93838 91177308-0d34-0410-b5e6-96231b3b80d8
