Some buffer swap intel render buffer fields (pf_num_pages & vbl_pending) are
also used for page flipping, so enable the code that sets & updates them on
965. This allows buffer swaps and page flips to work on 965 and prevents hangs
in LOCK_HARDWARE in the buffer swap case due to an uninitialized vbl_pending
field.
Fixes FDO #16118.
Add an --enable-motif option, which will enable the Motif widgets in
libGLw and link it with libXm. The Motif installation information will
be gathered from the motif-config script (this comes with LessTif) or
fallback to the standard autoconf checks.
To allow the location of the Motif headers to be set from configure, the
default setting of -I/usr/include/Motif1.2 has been moved into
configs/default and then passed to the Makefile through the MOTIF_CFLAGS
variable.
In glStencilFunc/Op/Mask() set both the front and back-face state, unless
GL_EXT_stencil_two_side is enabled. Before, we only set the front+back state
if GL_ATI_separate_stencil was enabled.
Ultimately, we probably should remove GL_EXT_stencil_two_side since it's
incompatible with GL 2.x.
Share almost all code with r500_fragprog now.
This also fixes Piglit's texrect-many test, which means that the compiz
bicubic plugin should work with hardware acceleration now.
This just makes the use of mklib more consistent throughout Mesa where
we always want to pass the linker and LDFLAGS when we might be making a
shared library.
When an input is marked in gl_program.InputsRead but is not actually read
in the final program (due to dead-code elimination or whatever), the order
of input registers must still match gl_program.InputsRead. This is done
even more explicitly now.
Use an abstracted instruction scheduling and register allocation algorithm
that we will be able to share with r300_fragprog.
Unlike the original emit code, this code tries to pair instructions that
only use the RGB part of the ALU with instructions that only use the alpha
part. However, the pairing algorithm still has some shortcomings;
for example, it doesn't generate optimal code for the emulation of LIT.
