2012-05-24Remove the PTX back-end and all of its artifacts (triple, etc.)Justin Holewinski
This back-end was deprecated in favor of the NVPTX back-end. NV_CONTRIB git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157417 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-01Change the PassManager from a reference to a pointer.Bill Wendling
The TargetPassManager's default constructor wants to initialize the PassManager to 'null'. But it's illegal to bind a null reference to a null l-value. Make the ivar a pointer instead. PR12468 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155902 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-28Enable machine code verification in the entire code generator.Jakob Stoklund Olesen
Some targets still mess up the liveness information, but that isn't verified after MRI->invalidateLiveness(). The verifier can still check other useful things like register classes and CFG, so it should be enabled after all passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153615 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-21Clear virtual registers after they are no longer referenced.Andrew Trick
Passes after RegAlloc should be able to rely on MRI->getNumVirtRegs() == 0. This makes sharing code for pre/postRA passes more robust. Now, to check if a pass is running before the RA pipeline begins, use MRI->isSSA(). To check if a pass is running after the RA pipeline ends, use !MRI->getNumVirtRegs(). PEI resets virtual regs when it's done scavenging. PTX will either have to provide its own PEI pass or assign physregs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151032 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-10PTX no longer needs to provide its own backend.Andrew Trick
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150227 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-10RegAlloc superpass: includes phi elimination, coalescing, and scheduling.Andrew Trick
Creates a configurable regalloc pipeline. Ensure specific llc options do what they say and nothing more: -reglloc=... has no effect other than selecting the allocator pass itself. This patch introduces a new umbrella flag, "-optimize-regalloc", to enable/disable the optimizing regalloc "superpass". This allows for example testing coalscing and scheduling under -O0 or vice-versa. When a CodeGen pass requires the MachineFunction to have a particular property, we need to explicitly define that property so it can be directly queried rather than naming a specific Pass. For example, to check for SSA, use MRI->isSSA, not addRequired<PHIElimination>. CodeGen transformation passes are never "required" as an analysis ProcessImplicitDefs does not require LiveVariables. We have a plan to massively simplify some of the early passes within the regalloc superpass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150226 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-08Codegen pass definition cleanup. No functionality.Andrew Trick
Moving toward a uniform style of pass definition to allow easier target configuration. Globally declare Pass ID. Globally declare pass initializer. Use INITIALIZE_PASS consistently. Add a call to the initializer from CodeGen.cpp. Remove redundant "createPass" functions and "getPassName" methods. While cleaning up declarations, cleaned up comments (sorry for large diff). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150100 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-04TargetPassConfig: confine the MC configuration to TargetMachine.Andrew Trick
Passes prior to instructon selection are now split into separate configurable stages. Header dependencies are simplified. The bulk of this diff is simply removal of the silly DisableVerify flags. Sorry for the target header churn. Attempting to stabilize them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149754 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-03Added TargetPassConfig. The first little step toward configuring codegen passes.Andrew Trick
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149672 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-02Move global variables in TargetMachine into new TargetOptions class. As an APINick Lewycky
change, now you need a TargetOptions object to create a TargetMachine. Clang patch to follow. One small functionality change in PTX. PTX had commented out the machine verifier parts in their copy of printAndVerify. That now calls the version in LLVMTargetMachine. Users of PTX who need verification disabled should rely on not passing the command-line flag to enable it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145714 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-16Sink codegen optimization level into MCCodeGenInfo along side relocation modelEvan Cheng
and code model. This eliminates the need to pass OptLevel flag all over the place and makes it possible for any codegen pass to use this information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144788 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-17Add support for a new extension to the .file directive:Nick Lewycky
.file filenumber "directory" "filename" This removes one join+split of the directory+filename in MC internals. Because bitcode files have independent fields for directory and filenames in debug info, this patch may change the .o files written by existing .bc files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142300 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-20- Move CodeModel from a TargetMachine global option to MCCodeGenInfo.Evan Cheng
- Introduce JITDefault code model. This tells targets to set different default code model for JIT. This eliminates the ugly hack in TargetMachine where code model is changed after construction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135580 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-08Eliminate asm parser's dependency on TargetMachine:Evan Cheng
- Each target asm parser now creates its own MCSubtatgetInfo (if needed). - Changed AssemblerPredicate to take subtarget features which tablegen uses to generate asm matcher subtarget feature queries. e.g. "ModeThumb,FeatureThumb2" is translated to "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134678 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-17Use the verbose asm flag instead of a new flag for decoding the LSDA.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133292 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-17Add an option that allows one to "decode" the LSDA.Bill Wendling
The LSDA is a bit difficult for the non-initiated to read. Even with comments, it's not always clear what's going on. This wraps the ASM streamer in a class that retains the LSDA and then emits a human-readable description of what's going on in it. So instead of having to make sense of: Lexception1: .byte 255 .byte 155 .byte 168 .space 1 .byte 3 .byte 26 Lset0 = Ltmp7-Leh_func_begin1 .long Lset0 Lset1 = Ltmp812-Ltmp7 .long Lset1 Lset2 = Ltmp913-Leh_func_begin1 .long Lset2 .byte 3 Lset3 = Ltmp812-Leh_func_begin1 .long Lset3 Lset4 = Leh_func_end1-Ltmp812 .long Lset4 .long 0 .byte 0 .byte 1 .byte 0 .byte 2 .byte 125 .long __ZTIi@GOTPCREL+4 .long __ZTIPKc@GOTPCREL+4 you can read this instead: ## Exception Handling Table: Lexception1 ## @LPStart Encoding: omit ## @TType Encoding: indirect pcrel sdata4 ## @TType Base: 40 bytes ## @CallSite Encoding: udata4 ## @Action Table Size: 26 bytes ## Action 1: ## A throw between Ltmp7 and Ltmp812 jumps to Ltmp913 on an exception. ## For type(s): __ZTIi@GOTPCREL+4 __ZTIPKc@GOTPCREL+4 ## Action 2: ## A throw between Ltmp812 and Leh_func_end1 does not have a landing pad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133286 91177308-0d34-0410-b5e6-96231b3b80d8
