Execute before folding loads, because we don't check if it's legal
in lower_mods.
Ensure that a value's insn pointer is updated when transferring it
to a different instruction.
Fix the following GCC warning.
loop_controls.cpp: In function 'int calculate_iterations(ir_rvalue*, ir_rvalue*, ir_rvalue*, ir_expression_operation)':
loop_controls.cpp:88: warning: format not a string literal and no format arguments
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.
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
Changes in v3:
- Also change trace, which I forgot about
Changes in v2:
- No longer adds tessellation shaders
Currently each shader cap has FS and VS versions.
However, we want a version of them for geometry, tessellation control,
and tessellation evaluation shaders, and want to be able to easily
query a given cap type for a given shader stage.
Since having 5 duplicates of each shader cap is unmanageable, add
a new get_shader_param function that takes both a shader cap from a
new enum and a shader stage.
Drivers with non-unified shaders will first switch on the shader
and, within each case, switch on the cap.
Drivers with unified shaders instead first check whether the shader
is supported, and then switch on the cap.
MAX_CONST_BUFFERS is now per-stage.
The geometry shader cap is removed in favor of checking whether the
limit of geometry shader instructions is greater than 0, which is also
used for tessellation shaders.
WARNING: all drivers changed and compiled but only nvfx tested
