Count int and float constants independently. Since there are only
few i# constants available and hundreds of c# constants, it would
be too easy to end up with an i# declaration out of its range.
Pixel shaders do not have address registers a#, only one
loop register aL. Our only hope is to assume the address
register is in fact a loop counter and replace it with aL.
Do not translate ARL instruction for pixel shaders -- MOVA
instruction is only valid for vertex saders.
Make it more explicit relative addressing of inputs is only valid
for pixel shaders and constants for vertex shaders.
Depth-only and stencil-only clears should mask out depth/stencil from the
output, mask out stencil/input from input, and OR or ADD them together.
However, due to a typo they were being ANDed, resulting in zeroing the buffer.
The current context should be notified when the the front/back buffers
of the current drawable are swapped. The notification was skipped when
xmesa_strict_invalidate is false (the default).
This fixes fdo bug #29774.
(cherry picked from commit 03224f492d)
Enable some extensions now that the needed tokens are defined in
GLES/glext.h and GLES2/glext.h. Update the prototype of MultiDrawArrays
now that the prototype of _mesa_MultiDrawArraysEXT has been updated.
(cherry picked from commit 9ca59b2427)
This fixes an error in GLAPI ES. My build is ok with or without this
patch, and the error affects others' setups.
[Patch from Francesco Marella]
(cherry picked from commit e3c46cf586)
The latest glext.h defines GL_FIXED. Test GL_OES_fixed_point instead to
decide whether to define GLfixed and GLclampx.
This fixes fdo bug #30205.
(cherry picked from commit cad87ebc3a)
The shadow versions of the texture targets use an extra component
(Z) to express distance from light source to the fragment.
Fixes the shadowtex demo with llvmpipe.
(cherry picked from commit 95254bbd2d)
This fixes a DRM deadlock in the cubestorm xscreensaver, because somehow
there must not be 2 different BOs relocated in one CS if both BOs back
the same handle. I was told it is impossible to happen, but apparently
it is not, or there is something else wrong.
(cherry picked from commit 0b9eb5c9bb)
when setting negative integers to bitfields we could overwrite
other parts of it. So mask the value to be written correctly.
This is used quite often in the driver - hope it doesnt affect
performace or uncover behaviour relied before...
fixes strange effects when setting negative lodbias on evergreen
A number of other files had to be updated as well because const
qualifiers were added to the glMultiDrawArrays() function.
Also, GL_FIXED is now defined in glext.h.
Fixes the following GCC warning.
i915_screen.c: In function 'i915_get_shader_param':
i915_screen.c:184: warning: control reaches end of non-void function
Fixes the following GCC warning.
i915_screen.c: In function 'i915_get_shader_param':
i915_screen.c:147: warning: implicit declaration of function 'draw_get_shader_param'
This is a follow-up to commit a508d2dddc.
Fixes the following GCC warning.
id_screen.c: In function 'identity_screen_create':
id_screen.c:317: warning: assignment from incompatible pointer type
This is a follow-up to commit a508d2dddc.
Fixes the following GCC warning.
rbug_screen.c: In function 'rbug_screen_create':
rbug_screen.c:331: warning: assignment from incompatible pointer type
Note, BTW, that the Gallium implementation returns 0.5, which seems
to violate the GLSL spec, where it should return 0.0 instead.
Not sure whether changing it to 0 is correct or not.
This turns on if conversion and unlimited loop unrolling if control
flow is not supported.
NOTE: this will change the behavior of r300g and any other driver
that doesn't advertise control flow
