We now express arrays in terms of indirect addressing. For example:
dst = a[i];
becomes:
MOV dst, TEMP[1 + TEMP[2].y];
At instruction-emit time indirect addressing is converted into ARL/
ADDR-relative form:
ARL ADDR.x, TEMP[2].y;
MOV dst, TEMP[1 + ADDR.x];
This fixes a number of array-related issues. Arrays of arrays and complex
array/struct nesting works now.
There may be some regressions, but more work is coming.

The Swizzle and Size fields carry all the info we need now.

This is a step toward better array handling code. In particular, when more
than one operand of an instruction uses indirect addressing, we'll need some
temporary instructions and registers. By converting IR storage to instruction
operands all in one place (emit_instruction()) we can be smarter about this.
Also, somewhat better handling of dst register swizzle/writemask handling.
This results in tighter writemasks on some instructions which is good for
SOA execution.
And, cleaner instruction commenting with inst_comment().
Next: remove some more dead code and additional clean-ups...

This lets one specify initial values for uniforms in the code, avoiding
the need to call glUniform() in some cases.

Fixes bug #17234
|
|
|
|
This fixes cases such as:
vec4 v4;
vec2 v2;
v4.xz.yx = v2;
The last line now correctly compiles into MOV TEMP[1].xz, TEMP[0].yyxw;
Helps to fix the Humus Domino demo. See bug 19189.
|
|
Also, fix some RNDD vs. RNDZ confusion elsewhere.

MSVC may not support full C99, but supports more than plain C90. And
-pedantic without -std=c99 generates too many spurious warnings
(specially C++ style comments) to be of any use.
Note that using certain C99 features in the cross-platform parts of Gallium
is still not possible; namely mid-of-scope variable declarations and named
structure initializers will break MSVC builds.

Now only the samplers that are actually used by texture() functions are
saved in the uniform variable list. Before, we could run out of samplers
if too many were declared while only some of them were actually used.
|
|
This lets GLSL shaders use up to 16 samplers.
Fixed function is still limited to 8 textures.
Tested with progs/glsl/samplers.c

The max texture coord units is still 8. All the fixed-function paths are
still limited to 8 too. But GLSL shaders can use more samplers now.
Note that some texcoord-related data structures are declared to be 16
elements in size rather than 8. This just simplifies the code in a few
places; the extra elements aren't accessible to the user.
These changes haven't been extensively tested yet, but sanity checking has
been done.
It should be possible to increase the max image units/samplers to 32 without
doing anything special. Beyond that we'll need longer bitfields in a few
places.

The DrawPixels path was missing glViewport care, so blender's toolbar icons
would go to the wrong places.
Bug #19118.
|
|
This lets us avoid software fallbacks when clients forget to turn some state
off (engine demo) or just do crazy things to test conformance (OGLC).
This should probably be brought into mesa generic code so other drivers can
make use of it.
Bug #19016.
