2013-03-30[mips] Fix definitions of multiply, multiply-add/sub and divide instructions.Akira Hatanaka
The new instructions have explicit register output operands and use table-gen patterns instead of C++ code to do instruction selection. Mips16's instructions are unaffected by this change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178403 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-28[Mips Assembler] Add support for OR macro with imediate opperandJack Carter
Mips assembler supports macros that allows the OR instruction to have an immediate parameter. This patch adds an instruction alias that converts this macro into a Mips ORI instruction. Contributer: Vladimir Medic git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178316 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-28[Mips Assembler] Add alias definitions for jalJack Carter
Mips assembler allows following to be used as aliased instructions: jal $rs for jalr $rs jal $rd,$rd for jalr $rd,$rs This patch provides alias definitions in td files and test cases to show the usage.

2013-03-04[mips] Print move instructions.Akira Hatanaka

2013-02-07[mips] Add definition of JALR instruction which has two register operands. ↵Akira Hatanaka
Change the original JALR instruction with one register operand to be a pseudo-instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174657 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-05This patch that sets the EmitAlias flag in td files Jack Carter
and enables the instruction printer to print aliased instructions. Due to usage of RegisterOperands a change in common code (utils/TableGen/AsmWriterEmitter.cpp) is required to get the correct register value if it is a RegisterOperand. Contributer: Vladimir Medic git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174358 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-18This is a resubmittal. For some reason it broke the bots yesterdayJack Carter
but I cannot reproduce the problem and have scrubed my sources and even tested with llvm-lit -v --vg. Removal of redundant code and formatting fixes. Contributers: Jack Carter/Vladimir Medic git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172842 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-12This patch tackles the problem of parsing Mips Jack Carter
register names in the standalone assembler llvm-mc. Registers such as $A1 can represent either a 32 or 64 bit register based on the instruction using it. In addition, based on the abi, $T0 can represent different 32 bit registers. The problem is resolved by the Mips specific AsmParser td definitions changing to work together. Many cases of RegisterClass parameters are now RegisterOperand. Contributer: Vladimir Medic git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172284 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-11Expose move to/from coprocessor instructions in MIPS64 mode.David Chisnall
Note: [D]M{T,F}CP2 is just a recommended encoding. Vendors often provide a custom CP2 that interprets instructions differently and may wish to add their own instructions that use this opcode. We should ensure that this is easy to do. I will probably add a 'has custom CP{0-3}' subtarget flag to make this easy: We want to avoid the GCC situation where every MIPS vendor makes a custom fork that breaks every other MIPS CPU and so can't be merged upstream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165711 91177308-0d34-0410-b5e6-96231b3b80d8
