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.

Bad rebase presumably.

This fixes an error in GLAPI ES. My build is ok with or without this
patch, and the error affects others' setups.

The code that uses dname is currently ifdef'ed out.

Fix the following GCC warning.

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.

fbHeight is 0 in this case
uncovered by changes in b0bc026c and should fix kernel rejecting command
streams after that commit

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.

Include compiler.h for ASSERT symbol.

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.

Silences a compiler warning. Still need to add some assertions
for this case.

Remove all FEATURE tests in mesa/drivers/common/. They are not needed
and the code looks better without them.
|
|
Add dummy static inline definitions to syncobj.h when FEATURE_ARB_sync
is 0, and remove most FEATURE_ARB_sync tests.

They were intended to be used to build OpenGL ES only DRI drivers, but
that never happened.

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

Currently GLSL IR forbids any vector comparisons, and defines "ir_binop_equal"
and "ir_binop_nequal" to compare all elements and give a single bool.
This is highly unintuitive and prevents generation of optimal Mesa IR.
Hence, first rename "ir_binop_equal" to "ir_binop_all_equal" and
"ir_binop_nequal" to "ir_binop_any_nequal".
Second, readd "ir_binop_equal" and "ir_binop_nequal" with the same semantics
as less, lequal, etc.
Third, allow all comparisons to acts on vectors.

If the loop ends with an if with one break or in a single break unroll
it. Loops that end with a continue will have that continue removed by
the redundant jump optimizer. Likewise loops that end with an
if-statement with a break at the end of both branches will have the
break pulled out after the if-statement.
Loops of the form
for (...) {
do_something1();
if (cond) {
do_something2();
break;
} else {
do_something3();
}
}
will be unrolled as
do_something1();
if (cond) {
do_something2();
} else {
do_something3();
do_something1();
if (cond) {
do_something2();
} else {
do_something3();
/* Repeat inserting iterations here.*/
}
}
ir_lower_jumps can guarantee that all loops are put in this form
and thus all loops are now potentially unrollable if an upper bound
on the number of iterations can be found.
