Description
I'm seeing an error when trying to use llvm.minimum.f64 and llvm.maximum.f64 on arm (32bits).
define double @call_maximum_fp128(double %x, double %y) unnamed_addr #1 {
start:
%0 = tail call double @llvm.maximum.f64(double %x, double %y)
ret double %0
}
declare double @llvm.maximum.f64(double, double)
attributes #1 = { inlinehint uwtable "target-cpu"="generic" "target-features"="+strict-align,+v6,+vfp2,-d32" }LLVM ERROR: Cannot select: 0xa8483e8: i32 = setcc 0xa8480a0, Constant:i64<-9223372036854775808>, seteq:ch
