2011-12-07Add bundle aware API for querying instruction properties and switch the codeEvan Cheng
generator to it. For non-bundle instructions, these behave exactly the same as the MC layer API. For properties like mayLoad / mayStore, look into the bundle and if any of the bundled instructions has the property it would return true. For properties like isPredicable, only return true if *all* of the bundled instructions have the property. For properties like canFoldAsLoad, isCompare, conservatively return false for bundles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146026 91177308-0d34-0410-b5e6-96231b3b80d8

Lay some groundwork for converting to MC-based asm printer. This is the first of probably many patches to bring the back-end back up-to-date with all of the recent MC changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140697 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-11- Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfoEvan Cheng
and MCSubtargetInfo. - Added methods to update subtarget features (used when targets automatically detect subtarget features or switch modes). - Teach X86Subtarget to update MCSubtargetInfo features bits since the MCSubtargetInfo layer can be shared with other modules. - These fixes .code 16 / .code 32 support since mode switch is updated in MCSubtargetInfo so MC code emitter can do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134884 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-28- Rename TargetInstrDesc, TargetOperandInfo to MCInstrDesc and MCOperandInfo andEvan Cheng
sink them into MC layer. - Added MCInstrInfo, which captures the tablegen generated static data. Chang TargetInstrInfo so it's based off MCInstrInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134021 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-25PTX: Reverting implementation of i8.Dan Bailey
The .b8 operations in PTX are far more limiting than I first thought. The mov operation isn't even supported, so there's no way of converting a .pred value into a .b8 without going via .b16, which is not sensible. An improved implementation needs to use the fact that loads and stores automatically extend and truncate to implement support for EXTLOAD and TRUNCSTORE in order to correctly support boolean values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133873 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-24PTX: Add support for i8 type and introduce associated .b8 registersDan Bailey
The i8 type is required for boolean values, but can only use ld, st and mov instructions. The i1 type continues to be used for predicates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133814 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-20PTX: Add basic register spilling codeJustin Holewinski
The current implementation generates stack loads/stores, which are really just mov instructions from/to "special" registers. This may not be the most efficient implementation, compared to an approach where the stack registers are directly folded into instructions, but this is easier to implement and I have yet to see a case where ptxas is unable to see through this kind of register usage and know what is really going on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133443 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-02Extend initial support for primitive types in PTX backendChe-Liang Chiou
- Allow i16, i32, i64, float, and double types, using the native .u16, .u32, .u64, .f32, and .f64 PTX types. - Allow loading/storing of all primitive types. - Allow primitive types to be passed as parameters. - Allow selection of PTX Version and Shader Model as sub-target attributes. - Merge integer/floating-point test cases for load/store. - Use .u32 instead of .s32 to conform to output from NVidia nvcc compiler.
