* [mips] Add definition of JALR instruction which has two register operands. ↵Akira Hatanaka2013-02-071-0/+3
| | | | | | | | | | 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
* This patch that sets the EmitAlias flag in td files Jack Carter2013-02-051-13/+20
| | | | | | | | | | | | | | | 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.

* This patch tackles the problem of parsing Mips Jack Carter2013-01-121-49/+68
| | | | | | | | | | | | | | | | | | | | 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

* Expose move to/from coprocessor instructions in MIPS64 mode.David Chisnall2012-10-111-0/+30
| | | | | | | | | | | | | 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
