Dear Alex, all,
I was looking for fcvt.d.{w,l}{,u} in RISCVInstrInfoD and I'm not sure to
understand the current definitions:
138 def FCVT_D_W : FPUnaryOp_r<0b1101001, 0b000, FPR64, GPR,
"fcvt.d.w"> {
139 let rs2 = 0b00000;
140 }
141
142 def FCVT_D_WU : FPUnaryOp_r<0b1101001, 0b000, FPR64, GPR,
"fcvt.d.wu"> {
143 let rs2 = 0b00001;
144 }
162 def FCVT_D_L : FPUnaryOp_r_frm<0b1101001, FPR64, GPR, "fcvt.d.l">
{
163 let rs2 = 0b00010;
164 }...

[LLVMdev] TableGen Style Conventions
This probably qualifies as bikeshedding, but how strict are the style
norms for TableGen? Some aspects of it, like individually and
consecutively declaring all *_ENC variables in this manner:
class ADDU_QB_ENC : ADDU_QB_FMT<0b00000>;
To be used only once, in this manner:
def ADDU_QB : ADDU_QB_ENC, ADDU_QB_DESC;
Seem like avoidable clutter to me. The files tend to be pretty big, and
I think that collapsing assignments like that could make them more
readable.
I'm new to this, so let me know if I'm missing som...

[LLVMdev] Backend Tablegen Instruction Definition
...ycle Rt
I’ve defined a stand-alone instruction definition (as opposed to using the type-I template) that is as follows:
//rdcycle
def RDCYCLE: InstRISCV<4, (outs GR32:$dst), (ins), ([set GC32:$dst])>{
field bits<32> Inst;
bits<5> dst;
let Inst{31-20} = 0b000000000000;
let Inst{19-15} = 0b00000;
let Inst{14-12} = 0b010;
let Inst{11- 7} = dst;
let Inst{6 - 0} = 0b1110011;
}
However, the compilation fails with the follow:
