[LLVMdev] comparison pattern trouble
Our architecture has 1-bit boolean predicate registers.
I've defined comparison
def NErrb : InstTCE<(outs I1Regs:$op3), (ins I32Regs:$op1,I32Regs:$op2), "", [(set I1Regs:$op3, (setne I32Regs:$op1, I32Regs:$op2))]>;
But then I end up having the following bug:
Code
%0 = zext i8 %data to i32
%1 = zext i16 %crc to i32
%2 = xor i32 %1, %0
%3 = and i32 %2, 1
%4 = icmp...

[LLVMdev] floating point immediate problem
I tried to generate pattern for instruction which transports floating
point immediate to a floating point register.
def MOVF32fk : InstTCE<(outs F32Regs:$dst), (ins f32imm:$val),
"$val -> $dst;",
[(set F32Regs:$dst, (f32 imm:$val))]>;
This causes an type contradiction:

[LLVMdev] float16/half float support situation? (and a problem)
...ng problems with this.
first I just tried to use fp16 data type, without any support in
backend. This was expected to fail.
I got error:
LLVM ERROR: Cannot select: 0x2f566b0: i32 = fp32_to_fp16 0x2f66bb0 [ID=876]
So I created an instruction pattern which matches this fp32_to_fp16
def CFHrf : InstTCE<(outs R32IRegs:$op2), (ins R32FPRegs:$op1), "",
[(set R32IRegs:$op2, (fp32_to_fp16 R32FPRegs:$op1))]>;
But then I got error
/tmp/tcecc-dKBdca/GenInstrInfo.td:30:91: error: Variable not defined:
'fp32_to_fp16'
