-mstackrealign causes stack corruption on MinGW. And without it the ability
to use SSE instrinsics goes down the drain. Even if we use
__attribute__((force_align_arg_pointer)) for the functions we explicitly
use SSE instrinsics, the SSE code automatically generated by gcc will
cause assertion failures. What a nightmare.
Thankfully LLVM gets this right, so all runtime generated SSE code just
works. rtasm code doesn't assume 16byte alignment. Therefore the bulk of
our performance sensitive code is not affected by this.
Still, intrinsics can be convenient, and it would be nice
to get this working again some day, sp will try to get a reduced test
case.
Add support for begin/end in each CS so we don't get any other
processes rendering in between.
TODO:
blame other parts of driver for this not working like Z.
1: add rv530 support
- num z pipes cap
- add proper start/finish query options for rv530
2: convert to use linked list properly.
3: add flushing required check.
4: initial Z top disabling support.
TODO:
make it actually work on my rv530.
SUBDIRS just takes PROGRAM_DIRS value. If PROGRAM_DIRS gets set
to the empty string (as can happen when building only OSMesa), a
'for' loop will lack anything to iterate over, causing a parse
error.
This fixes the issue by making sure SUBDIRS is the null string
when PROGRAM_DIRS is, and wrapping the for loops in if's, causing
them only to execute if there are directories to iterate over.
Once the clipping distance is calculated and stored per vertex, the
distances can be re-used when clipping is actually performed. This
doesn't have any immediate benefit, but it paves the way for
implementing gl_ClipDistance in vertex shaders and result.clip[] in
vertex programs.
This has not produces any oglconform regressions on my G31 system
which uses software TNL.

As a result, EGL_NONE is no longer a valid client API. And it is
possible that no config supports the current bound API.

This allows an EGL driver to be compiled together with libEGL.so. It
eliminates the need to specify a driver, or support module loading on
new platforms.
