This fixes the glean/glsl1 "texture2D(), with bias" test when using SSE.
|

This fixes some issues when "return"ing from nested loops/conditionals.

Values outside the writemask are set in the destination to {0,0,0,1}

Manual merge of ureg changes on the branch. Too much unrelated stuff
for a proper merge.

Can be implemented with CMP src2, src1, src0
|
|
This has several advantages over the u_
- not hand written
- no intermediate memcpy of raw pixels
- supports 4 ubytes in addition to floats
- no need to pass a pipe_transfer
It also has (hopefully temporary) limitations:
- no support for YUV
- no support for SRGB

Namelly, explicitly distinguish formats coded by arithmetic manipulation,
from formats layed out in array.
|
|
At least not until stabilizes, to reduce noise.
|
|
|
|
There are some inconsistencies in pipe_format, but above all, there
simply aren't enough bits in an enum to conveniently store all
information about a pixel format we need to be able to dynamically
generate pixel packing/unpacking code.

Simplifies migration to tgsi_ureg.
(cherry picked from commit f574398c07c41cb8d31249a7186fc178ef7d552a)
|
|
When translating an incoming shader (rather than building one from scratch)
it's preferable to be able to call a single, generic instruction emitter
rather than figuring out which of the opcode-specific functions to call.

Fall back to interpreter for now. This doesn't happen very often.
|

SOA dependencies can happen when a register is used both as a source and
destination and the source is swizzled. For example:
MOV T, T.yxwz; would expand into:
MOV t0, t1;
MOV t1, t0;
MOV t2, t3;
MOV t3, t2;
The second instruction will produce the wrong result since we wrote to t0
in the first instruction. We need to use an intermediate temporary to fix
this.
This will take more work to fix for all TGSI instructions. This seems to
happen with MOV instructions more than anything else so fix that case now
and warn on others.
Fixes piglit glsl-vs-loop test (when not using SSE). See bug 23317.

Users of the parser can make use of this.
