[sldev] Linux non-x86 SSE build script

[Paul TBBle Hampson]

Hi,

Just preparing the 1.18.1.2 Debian packages, I've come across an issue
where the build script now tries to build certain files with  -msse
-mfpmath=sse or -msse2 -mfpmath=sse.

I was just wondering what the plan to move forward with this is, given
that gcc won't accept those flags on non-x86 architectures, which to my
mind implies this probably wouldn't have built on PowerPC Mac OS X
or Sparc Solaris either.

I'm considering just throwing #ifdefs around the code that uses the SSE
and SSE2, and then doing some kind of surgery to SConstruct to ignore
the _sse.cpp and _sse2.cpp files on non-x86.

But I was hoping there's some kind of upstream plan to fix this, to save
me duplicating any work here.

Of course, if anyone on-list's already solved this, I'm interested in
patches too. ^_^

It's also worth keeping in mind that eventually we could end up with a
Sparc Linux port, if someone wants one. (Really, it'lll simply be some
junction of the Sparc Solaris port and the PowerPC Linux port...)

I haven't put anything in Jira about this yet, I'm hoping to get the lay
of the land first.

we'd be running around in darkened rooms, popping pills and
