--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
We certainly need preprocessed source + full gcc command line used to compile
it for the TU that is miscompiled. Ideally, if it is really dgemv_n.c and so
doesn't really call other function also make it __attribute__((noipa)) and add
main that sets up the arrays etc. with values on which it reproduces.
Does -fno-ipa-modref help?
