So you can compile with llvm only on that supported and tested platforms, but
always install the resulting swrastg (rather than classic swrast).
Thanks. Looking closer, I notice that swrastg is already built
everywhere except on Hurd, just not installed. So it's probably just a
matter of adding the llvm build dependency on kfreebsd-*.
Also note that on current git (will be in 7.12/8.0) swrastg was renamed to
swrast (so there are two swrast now: the gallium one and the classic one,
built
under different directories):

id=5fe54df58f31e5d321f7cbd5b095eb8c2417deb1
There are a few options when we package that version:
- Revert this commit;
- Use a diversion in the libgl1-mesa-dri-experimental package;
- Assume the Gallium driver is mature enough and ship it in the
libgl1-mesa-dri package.
Nothing that needs to be decided now, though.
Cheers,
Sven

llvmpipe currently doesn't work on powerpc, but it might work on other
architectures such as ARM.
Note that swrastg can be built with or without llvm: in the first case it is
commonly called llvmpipe [1], in the second case it is called softpipe.
Strictly speaking, llvmpipe and softpipe are just the Gallium core
drivers, which can be used for building various kinds of driver
binaries, of which swrast_dri.so is but one.
They should both be better than classic swrast.
I'm afraid it's not that simple: softpipe should be more featureful than
classic swrast, but in contrast to llvmpipe, it's probably slower than
classic swrast for simple apps, which might be usable with classic
swrast but not with softpipe.

KiBi.
It's quite simple. It affects
- swrast when dri-experimental is installed
- gallium based drivers - fallbacks are now llvm based (currently r300?)
Note that mesa currently builds r600g but does not ship it, perhaps it
could be also added to dri-experimental.
I am not sure how useful the version in 7.10 is but it should improve
over time.
