How to describe the RegisterInfo?
...I understand it correctly. My
first trial was like below(to make things simple, I remove some WORD/QWORD
register class):
let Namespace = "IntelGPU" in {
foreach Index = 0-15 in {
def sub#Index : SubRegIndex<32, !shl(Index, 5)>;
}
}
class IntelGPUReg<string n, bits<13> regIdx> : Register<n> {
bits<2> HStride;
bits<1> regFile;
let Namespace = "IntelGPU";
let HWEncoding{12-0} = regIdx;
let HWEncoding{15} = regFile;
}
// here I define the whole 4096 byte registers
foreach Index = 0-4095 in {
def Rb#Index : IntelGPUReg <&qu...

How to describe the RegisterInfo?
Hi Escha,
Great to have your comment! Do you have any specific reason for not doing
like this?
I am not sure whether I understand your point correctly. For "just model
one thread",
do you mean "only considering ONE of the 8/16 working lanes that running in
lock-step way"??
For my case, may be something like I only need to define r0~r127 as
register for i32 register (each r#
