Re: propolice support for linux

[Ulrich Drepper <drepper@gmail.com>]

Aside from all the arguments about why this patch isn't good for the
kernel, everybody should be aware that the ProPolice gcc patches are
pretty unusable.  They rely in recognizing certain tree patterns which
for some architectures do not exist, and for others can look
differently, depending on the optimization.  To paraphrase one of the
gcc developers: "this kind of functionality should be written to work
_with_ gcc, not _against_ it as the propolice patch does".

Before you suggest using something like this patch you better first
inform yourself by asking the people who actually know the code which
is modified.
