I was able to reduce the test case to:
target datalayout = "e-m:e-p:64:64-i64:64-i128:128-n64-S128"
target triple = "riscv64-unknown-unknown-eabi-elf"
; Function Attrs: nofree nosync nounwind
define internal i32 @main_dispatch_72(i8* %i5, <2 x float> %i44, <2 x float> %i61, <2 x i32> %i65) {
bbi:
%i45 = fcmp uno <2 x float> %i44, zeroinitializer
%i62 = fcmp oeq <2 x float> %i44, <float 0xFFF0000000000000, float 0xFFF0000000000000>
%i63 = fcmp oeq <2 x float> %i44, <float 0x7FF0000000000000, float 0x7FF0000000000000>
%i64 = fcmp ogt <2 x float> %i44, zeroinitializer
%i66 = icmp ult <2 x i32> %i65, <i32 255, i32 255>
%i67 = select <2 x i1> %i64, <2 x float> <float 0x7FF0000000000000, float 0x7FF0000000000000>, <2 x float> <float 0x3810000000000000, float 0x3810000000000000>
%i68 = select <2 x i1> %i66, <2 x float> %i61, <2 x float> %i67
%i69 = select <2 x i1> %i63, <2 x float> <float 0x7FF0000000000000, float 0x7FF0000000000000>, <2 x float> %i68
%i70 = select <2 x i1> %i62, <2 x float> zeroinitializer, <2 x float> %i69
%i71 = select <2 x i1> %i45, <2 x float> %i44, <2 x float> %i70
%i72 = bitcast i8* %i5 to <2 x float>*
store <2 x float> %i71, <2 x float>* %i72, align 64
ret i32 0
}
Your code should trigger with `llc bug.ll -mcpu=generic-rv64 -mattr=+m,+a,+f,+d,+c -target-abi=lp64d`.
It looks like it's a case where your transformation is applied multiple times on the output produced by previous instances.
I'll revert this commit while this is being investigated.
Thanks,
Diego
