Hi,
I had asked about this on irc some time ago, it seemed to me that the
configure script was ignoring whether we gave it --enable-3dnow or
--enable-altivec. For now, variables are set to no, regardless of what
has been passed to the configure script for those options.
Please find a patch enclosed that reorders that, removes the
variables assignments since they are defaulted to the same value with
the ac_arg_enable_macros.
This does not change the current behavior that enables mmx on any i586
or i686. That might be a good idea to let people be able to disable it
with --disable-mmx (this might be useful to make packages for binary
distros).
MMX support doesnt compile on a 64 bits amd64, it's probably nasm
specific asm.
3dnow does not seem to change anything, but there are some comments
saying that adding -DUSE_3DNOW makes cinelerra not compiling. I see
this is only used in libmpeg3, I'm gonna have a look at it.
Regards,
Alexis.
