Hi,
this patch fixes problem with missing dump files with -flto and vectorizer
and also silence error in gcc.dg/20081223-1.c testcase. We ought to error
these even w/o -ffat-lto-objects, I will look into it ASAP.
We need to move these errors from varasm/wrapup into symtab finalization
that is obviously correct thing to do once we are fully unit-at-a-time
but it may contain surprises (from my past experiences).
Regtested ppc64-linux
* gcc.dg/20081223-1.c: Add -ffat-lto-objects.
* gcc.dg/vect/vect.exp: Add -ffat-lto-objects.
