[llvm-dev] restrict func param losing noalias when inlined

Given some code:
void func (float * restrict a, float *b) {
for (int i =0; i < 100; ++i) {
a[i] = b[i] + 1;
}
}
float * aa;
float * bb;
int main() {
func(aa, bb);
return 0;
}
produces IR that has the llvm.noalias intrinsic along with the !noalias
metadata:for both the load and store, however, AA returns MayAlias, I would
expect a NoAlias?
This is also an older version of llvm: 6 (yes, I know, sigh).
Thanks,
Ryan
