-Subject: [PATCH] middle-end: check explicitly for external or constants when
- checking for loop invariant [PR116817]
-
-Hi All,
-
-The previous check if a value was external was checking
-!vect_get_internal_def (vinfo, var) but this of course isn't completely right
-as they could reductions etc.
-
-This changes the check to just explicitly look at externals and constants.
-Note that reductions remain unhandled here, but we don't support codegen of
-boolean reductions today anyway.
-
-So at the time we do then this would have the be handled as well in lowering.
-
-Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
-
-Ok for master?
-
-Thanks,
-Tamar
