Hello,
As I see, among latest Mercurial commits official '-O2' support is
introduced [1] with required '-fno-strict-aliasing' addition.
I want to notice that '-fno-strict-aliasing' is unnecessary when uWSGI
is compiled for Python 3.x under GCC >= 4.3 [2], so
'-fno-strict-aliasing' could be added to CFLAGS after matching on Python
and GCC versions, like:
gcc_minor = int(gcc_version.split('.')[1])
if (sys.version_info[0] == 2) or (gcc_major < 4) or (gcc_major == 4
and gcc_minor < 3):
cflags = cflags + ['-fno-strict-aliasing']
Sorry me for being lazy and not providing real patch.
