* Widen the instruction encoder that TblGen emits to a 64 bits, which should ↵Owen Anderson2012-01-241-1/+1

* Improve Mips JIT.Bruno Cardoso Lopes2011-12-301-3/+12
| | | | | | | | | | | Implement encoder methods getJumpTargetOpValue and getBranchTargetOpValue for jmptarget and brtarget Mips tablegen operand types in the code emitter for old-style JIT. Rename the pc relative relocation for branches - new name is Mips::reloc_mips_pc16. Patch by Sasa Stankovic llvm-svn: 147382

* Add bundle aware API for querying instruction properties and switch the codeEvan Cheng2011-12-071-1/+1
| | | | | | | | | | | | | | 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. llvm-svn: 146026
* First chunk of MachineInstr bundle support.Evan Cheng2011-12-061-1/+1
| | | | | | | | | 1. Added opcode BUNDLE 2. Taught MachineInstr class to deal with bundled MIs 3. Changed MachineBasicBlock iterator to skip over bundled MIs; added an iterator to walk all the MIs 4. Taught MachineBasicBlock methods about bundled MIs llvm-svn: 145975
* Mips MC object code emission improvements:Bruno Cardoso Lopes2011-11-111-21/+36
| | | | | | | | | | "With this patch we can now generate runnable Mips code through LLVM direct object emission. We have run numerous simple programs, both C and C++ and with -O0 and -O3 from the output. The code is not production ready, but quite useful for experimentation." Patch and message by Jack Carter llvm-svn: 144414
* This patch handles unaligned loads and stores in Mips JIT. Mips backendBruno Cardoso Lopes2011-11-081-4/+140
| | | | | | | | | | | | implements unaligned loads and stores with assembler macro-instructions ulw, usw, ulh, ulhu, ush, and this patch emits corresponding instructions instead of these macros. Since each unaligned load/store is expanded into two corresponding loads/stores where offset for second load/store is modified by +3 (for words) or +1 (for halfwords). Patch by Petar Jovanovic and Sasa Stankovic. llvm-svn: 144081
* Final patch that completes old JIT support for Mips:Bruno Cardoso Lopes2011-10-181-5/+26
| | | | | | | | | | | | | | | | -Fix binary codes and rename operands in .td files so that automatically generated function MipsCodeEmitter::getBinaryCodeForInstr gives correct encoding for instructions. -Define new class FMem for instructions that access memory. -Define new class FFRGPR for instructions that move data between GPR and FPU general and control registers. -Define custom encoder methods for memory operands, and also for size operands of ext and ins instructions. -Only static relocation model is currently implemented. Patch by Sasa Stankovic llvm-svn: 142378
* One more patch towards JIT support for Mips.Bruno Cardoso Lopes2011-09-141-73/+125
| | | | | | | | | | | | | | - Add TSFlags for the instruction formats. The idea here is to use as much encoding as possible from getBinaryCodeForInstr, and having TSFLags formats for that would make it easier to encode most part of the instructions (since Mips encodings are pretty straightforward) - Improve the mips mechanism for compilation callback - Add Mips specific code for invalidating the instruction cache - Next patch will address wrong tablegen encoding Commit msg added by my own but the patch is from Sasa Stankovic. llvm-svn: 139688
* Added the infrastructute necessary for MIPS JIT support. Patch by VladimirBruno Cardoso Lopes2011-07-211-0/+193
Stefanovic. I removed the part that actually emits the instructions cause I want that to get in better shape first and in incremental steps. This also makes it easier to review the upcoming parts. llvm-svn: 135678
