they hurt performance, if they don't hurt performance, our configure
script should be improved. Additionally, many options are the default
(--enable-iconv) or make no sense on your architecture (--disable-altivec)
or look contradictory to me (--disable-stripping --disable-debug). But as
said all this is unrelated and it is much more failsafe if you continue
using ebuild.
Noted. On a further unrelated note, I've noticed that ffmpeg disables SSE
and SSSE3 (from configure output) even though the CPU is capable of it
(altivec and sse are USE flags and --disabled unless activated globally).
Apparently it's slow on Atom - so not sure of the impact of those --extra
compiler flags. I'll try removing them.
But this is certainly unrelated, and I'm not sure how to progress. If you
don't have any specific code points, I can start a binary search between
bf36dc50 and a0c6c8e5 and try to nail down the commit that introduced it.
Might take a while though :)
