Writing a compiler is time consuming and error prone in
order to allow r600g to further progress in the meantime
i wrote a simple tgsi assembler, it does stupid thing but
i would rather keep the code simple than having people
trying to optimize code it does.

Fixes glean glsl1 since 7b7845a076c933e096ac511b4184141ba194449a

If we bias x,y we still need to pass through z,w in case the shader
reads gl_FragCoord.z or .w.
Fixes fd.o bug 29183 (piglit glsl-bug-22603).
NOTE: This is a candidate for the 7.8 branch.
|
|
This should be more useful for developers and for bug triaging than
just generating wrong code.
|
|
Fixes glsl-vs-arrays. Bug #27388.
|
|
Fixes minor rasterization error detected by some tests.

Also move some initialization from screen init to pre-init, now
that it is possible.
Also import a new vmwgfx drm (1.3) header.

This makes it possible to prune modes already in pre-init.
We also keep these resources alive across server generations, and
they are implicitly closed on server exit.

Add a customizer callback just before initial config setting, so that the
customizer code can initialize the mode validator using the drm
file-descriptor.

We'll just get it from the returned drawable when we need it.

Avoids double locking glXLock in the X wire to event handlers.
|

It's supposed to be x - y * floor(x/y), not (x - y) * floor(x/y).

Top-level instructions now get NULL as their default type (since type is
irrelevant for things like ir_function), while ir_rvalues get error_type
by default.
This should make it easier to tell if we've forgotten to set a type. It
also fixes some "Conditional jump or move depends on uninitialized
value" errors in valgrind caused by ir_validate examining the type of
top level ir_instructions, which weren't set.
|
|
Assignments can only exist at the top level instruction stream; the
residual value is handled by assigning the value to a temporary and
returning an ir_dereference_variable of that temporary.
|
|
ir_to_mesa was updated for the _mesa_glsl_parse_state constructor
changes, but main.cpp was not.
|
|
Variables with mode ir_var_temporary were causing an out of bounds array
access and filling my screen with rubbish. I'm not sure if "temporary"
is the right thing to print.

It's really hard to believe that this case has been broken, but apparently
no test previously exercised it. So this commit adds such a test and fixes
it by making a copy of the argument token-list before expanding it.
This fix causes the following glean tests to now pass:
glsl1-Preprocessor test 6 (#if 0, #define macro)
glsl1-Preprocessor test 7 (multi-line #define)
|
|
Kind of missing the point to only do the side effects if the LHS
evaluates as true.
Fixes:
glsl1-|| operator, short-circuit
|
|
|
|
Fixes:
glsl1-struct (1)
glsl1-struct (2)
glsl1-struct (3)
glsl1-struct (4)

Fixes fd.o bug 29206.

Fixes:
draw_buffers-08.frag
draw_buffers-09.frag
glsl-vs-texturematrix-2
|
|
This is a work-around for an apparent bug in LLVM seen with piglit's
glsl-vs-sqrt-zero test.
|
|
If we put the protos in separate ir_functions, they wouldn't be found
at lookup time for linking.
Fixes:
glsl-fs-texture2d-bias
glsl-fs-texture2dproj-bias
glsl-fs-texture2dproj-bias-2
glsl-lod-bias
glsl1-texture2D(), computed coordinate

Previously, the compiler expected the result of the multiplication to
be of the same type as the vector. This is correct for square
matrices, but wrong for all others.
We fix this by instead expecting a vector with the same number of rows
as the matrix (for the case of M*v with a column vector) or the same
number of columns as the matrix (for v*M with a row vector).
This fix causes the following four glean tests to now pass:
glsl1-mat4x2 * vec4
glsl1-vec2 * mat4x2 multiply
glsl1-vec3 * mat4x3 multiply
glsl1-vec4 * mat3x4 multiply
|
|
Previously, we'd constant-fold up a value of vec4(1.0 - arg2, 0, 0, 0).
Fixes:
glsl1-mix(vec4) function

Instead, just use the incoming sampler param. Fixes many texture-using
piglit tests since the linker rework.
