Questions on Bug Reporting

[Aaron W. LaFramboise]

As I get more experience working with GCC, there are a two questions on
procedure that I still don't know the answer to:

1) If I find a bug, and figure out how to fix it right away, is it
better to file a bug report in Bugzilla, or just post the patch to
gcc-patches without opening a PR?

2) There are a whole lot of testsuite failures for the target I am
primarily interested in, Windows.  After investigating a failure, should
I file a bug report for it?  Should I submit patches to mark the PR as
XFAIL if I don't immediately have a fix for it?

Thanks,
