--- Comment #16 from Vittorio <zeccav at gmail.com> ---
If comment #15 is directed to me,
I believe I already did my part by exposing this issue on mesa bugzilla.
The C99 standard clearly states that such shifts are undefined and
then against the standard.
Mesa works on many platforms and it should be at least standard
compliant to ensure its correct execution.
Maybe this undefined behaviour provokes some glitches in mesa, maybe not.
I have not the expertise nor the time to submit patches.
Are you telling me nobody is going to fix these bugs?
If you are happy with that I am happy.
