Hi all, I find some some type errors in the commentary of *.td file. such as: lib/Target/Mips/MipsInstrFormats.td MipsRegisterInfo.td - Mips Register defs it should be MipsInstrFormats.td - Mips Instruction Formats lib/Target/Mips/MipsInstrInfo.td MipsInstrInfo.td - Mips Register defs it should be MipsInstrInfo.td - Target Description for Mips Target and some thing I think it is wrong in lib/Target/Mips/M...

Hi, I noticed one class in MipsInstrFormats.td:L46 -> Class MipsPseudo. I wonder whether I can use this. If does, I wonder what would be the right way to use.

I reiterate. You should fix the simulator. It is broken. The compiler is not. Fix what's broken. -Jim On Oct 7, 2011, at 1:11 PM, Gang-Ryung Uh wrote: > Hi, > > I noticed one class in MipsInstrFormats.td:L46 -> Class MipsPseudo. I wonder whether I can use this.

Hi All. This is an RFC for a proposed target specific X86 optimization for reducing code size in the encoding of AVX-512 instructions when possible. When the AVX512F instruction set was introduced in X86 it included additional 32 registers of 512bit size each ZMM0 - ZMM31, as well as additional 16 XMM registers XMM16-XMM31 and 16 YMM registers YMM16-YMM31. In order to encode the new registers of

Do you want to replace lui $2, %hi(g1) addiu $2, $2, %lo(g1) with this? la $2, g1 If that is the case, you can add this pattern. def op_la : Operand<i32>; def LA : FI<0x09, (outs CPURegs:$dst), (ins op_la:$addr0, op_la:$addr1), "la $dst, $addr0", [(set CPURegs:$dst, (add (MipsHi tglobaladdr:$addr0), (MipsLo tglobaladdr:$addr1)))], IIAlu>;

Hi, In order to emit "la $4,ADDR" instead of lui followed by addiu to load the data address, could you advise what is proper way to revise td files in the MIPS target?
