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.

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.

get_fp_input_mask()
This is a work-around the for the fact that we do fragment shader state
validation before vertex shader validation (see comments in state.c) so in
get_fp_input_mask() we can't rely on ctx->VertexProgram._Current being up to
date yet.
This fixes a glean glsl1 test failure.

|
The problem we're solving only occured when there was a user-defined
vertex shader but no fragment shader. Check for that case now.
Fixes glean api2 vertex array failure.

This reverts commit cdaaf8e107010624bed4abdf9553c0ef63c8b708.

We were accidentally using the fixed-function logic when a vertex shader was
being used.
|
|
|
|
Quite a few util modules were maintaining a single vertex buffer over multiple
frames, and potentially reusing it in subsequent frames. Unfortunately that
would force us into syncrhonous rendering as the buffer manager would be
forced to wait for the previous rendering to complete prior to allowing the
map.
This resolves that issue, but requires the state tracker to issue a few new
flush() calls at the end of each frame.

Some code cleanup is still in order.
|
|
Marking all surfaces as undefined was wrong and cause some glean failures
because glReadPixels was used after SwapBuffers.
|
|
By time we get around to rendering the cached bitmap, the current color may
have changed. Need to make sure we load the constant slot with the cached
color.

Dots is re-used if more than one light is enabled. Previously
the negate flag of dots may affect next light.

The clean-up call to pipe->set_vertex_buffers() should use the same
number of buffers as the first call.

If an application never calls glUniform() to set sampler variable values
they'll remain 0 (the default value/unit).
Now call _mesa_update_shader_textures_used() at link time in case glUniform()
is never called. program->TextureUsed[] will then be correct for state
validation.

This will warn the user that the shader being run may be using uninitialized
uniform variables.
