bool-vector-0.nitro.llvm-ir
Hi,
I found that there is invalid CodeGen for bool vectors, even before the
lowering.
Please see the attached LLVM IR.
I compiled it with:
opt -O3 -march=native <bool-vector-0.nitro.llvm-ir -o tutu.bc
llvm-dis tutu.bc
And then cat tutu.ll gives the following output:
; ModuleID = 'tutu.bc'
source_filename = "<stdin>"
; Function Attrs: norecurse nounwind readnone
define i1 @compute(<8 x float> %in) local_unnamed_addr #0 {
ret i1 true
}
attributes #0 = { norecurse nounwind readnone }
Which is *wrong*.
Regards,
Alex
