This is no longer needed since we added the new
_slang_loop_contains_continue_or_break() function/test.
|
|
The glean "function with early return (1)" test passes now.
|
|
|
|
|
|
Needed for "remove early returns" transformation.
|
|
This will need more testing, but no regressions seen so far.

Need to execute the for loop's increment code before we continue.
Add a slang_assemble_ctx::CurLoopOper field to keep track of the containing
loop and avoid the "cont if true" path in this situation.
Plus, assorted clean-ups.

|
|
|
The previous test failed for nested loops.

Just search the AST in _slang_can_unroll_for_loop().
|
|
We should just check if the loop contains a continue/break in the
_slang_can_unroll_for_loop() test function...

This is the start of a glsl-continue-return feature branch to support
a GLSL code generator option for 'continue' and 'return' statements.
Some targets don't support CONT or RET statements so we'll need to
try to generate code that does not use them...
|

glsl compiler will not generate OPCODE_SWZ, and as a first step it would
be translated away to a MOV anyway (why?), but later internally this opcode is
generated (for EXT_texture_swizzling).

Be clearer that this is the number of generic vertex program/shader
attributes, not counting the legacy attributes (pos, normal, color, etc).

Call the _mesa_set_enable() functions instead of driver functions, etc.
Also, add missing code for 1D/2D texture arrays.

If we're running a vertex program to emulated fixed-function, we still need
to treat vertex arrays/attributes as if we're in fixed-function mode.
This should probably be back-ported to Mesa 7.5 after a bit more testing.

When a GLSL sampler reads from an incomplete texture it should
return (0,0,0,1). Instead of jumping through hoops in all the drivers
to make this happen, just create/install a fallback texture with those
texel values.
Fixes piglit/fp-incomplete-tex on i965 and more importantly, fixes some
GPU lockups when trying to sample from missing surfaces. If a binding
table entry is NULL, it seems that sampling sometimes works, but not
always (lockup).
Todo: create a fallback texture for each type of texture target?

The CALL_DrawArrays was leaking the clear's primitives into the display
list with GL_COMPILE_AND_EXECUTE. Use _mesa_DrawArrays instead, which
doesn't appear to leak. Fixes piglit dlist-clear test.

Fixes #22181. R200 requires this since DP4 is used in hw tnl mode.
R300 prefers it (should be faster due to no instruction dependencies), but
both methods should be correct (when sw tcl is used though, MUL/MAD might
be faster). Probably doesn't make much difference for R100 since vertex progs
are executed in software anyway, but let's just keep it the same there too.

With 1D textures, GL_TEXTURE_WRAP_T should be ignored (only
GL_TEXTURE_WRAP_S should be respected). But the i965 hardware
seems to follow the value of GL_TEXTURE_WRAP_T even when sampling
1D textures.
This fix forces GL_TEXTURE_WRAP_T to be GL_REPEAT whenever 1D
textures are used; this allows the texture to be sampled
correctly, avoiding "imaginary" border elements in the T direction.
This bug was demonstrated in the Piglit tex1d-2dborder test.
With this fix, that test passes.

One warning message:
drm_i915_getparam: -22
was still being sent to fprintf(). This causes all Piglit tests to fail,
even with MESA_DEBUG=0.
Using _mesa_warning() to emit the message allows the general Mesa controls
for messages like this to be applied.

When out of memory (in at least one case, triggered by a longrunning
memory leak), this code will segfault and crash. By checking for the
out-of-memory condition, the system can continue, and will report
the out-of-memory error later, a much preferable outcome.

If there is no shared context, there is no purpose in rebinding the same
texture. In some artificial tests this improves performance 10% - 30%.
