MesaLib-9.1.1-ffs.patch

Mesa uses ffsll, which isn't present on Solaris. It is however present as a builtin in gcc, which is sufficient. But for unclear reasons the Mesa headers will only properly use that on a specific list of platforms, instead of all gcc compliations.

Attached patch removes this restrictive list and uses the builtins whenever gcc is used and the native versions are missing.
Comment 1 Alan Coopersmith 2013-03-28 15:20:10 UTC
For what it's worth Solaris 11 and later have ffsll(), but not older releases.
The patch to use the gcc builtins when possible makes sense to me.
Comment 2 Brian Paul 2013-04-02 15:27:48 UTC
Should be fixed with commit 95df2b28831147b3e7ce2a3b6257bf60c46b4ab4
