We need a slot for the stipple texture and the pixel shader already uses
32 textures (16 API slots + 16 FMASK slots).

The FILLED_SIZE counter is uninitialized at the beginning, so we can't use it.
Instead, use offset = 0, which is what we always do when not appending.
This unexpectedly fixes spec/ARB_texture_multisample/sample-position/*.
Yes, the test does use transform feedback.

When a rebase swizzle is provided and we call _mesa_swizzle_and_convert
after unpacking the source format we were always passing normalized=false.
We should pass true or false depending on the formats involved in the
conversion for the byte and float paths (the integer path cannot ever be
normalized).

Originally, get_alu_src was supposed to handle resolving swizzles and
things like that. However, now that basically every instruction we have
only takes scalar sources, we don't really need it anymore. The only case
where it's still marginally useful is for the mov and vecN operations that
are left over from SSA form. We can handle those cases as a special case
easily enough. As a side-effect, we don't need the vec_to_movs pass
anymore.
v2 Jason Ekstrand <[email protected]>:
- Rework the way we detect if we need an extra copy for swizzling. The
old code involved a pile of confusing switch fall-throughs; we now use a
loop.

negative
Section 2.3.1 (Errors) of the OpenGL 4.5 spec says:
"If a negative number is provided where an argument of type sizei or
sizeiptr is specified, an INVALID_VALUE error is generated.
This patch adds checks for negative buffer size values passed to different APIs.
It also moves up the check on other APIs that already had it, making it the first
error check performed in the function, for consistency.
While there may be other APIs throughtout the code lacking this check (or at least
not at the beginning of the function), this patch focuses on the cases that break
the dEQP tests listed below. It could be a good excersize for the future to check
all other cases, and improve consistency in the order of the checks throughout the
whole Mesa code base.
This fixes 5 dEQP test:
* dEQP-GLES3.functional.negative_api.state.get_attached_shaders
* dEQP-GLES3.functional.negative_api.state.get_shader_source
* dEQP-GLES3.functional.negative_api.state.get_active_uniform
* dEQP-GLES3.functional.negative_api.state.get_active_attrib

Currently, Mesa uses the lowering pass MOD_TO_FRACT to implement
mod(x,y) as y * fract(x/y). This implementation has a down side though:
it introduces precision errors due to the fract() operation. Even worse,
since the result of fract() is multiplied by y, the larger y gets the
larger the precision error we produce, so for large enough numbers the
precision loss is significant. Some examples on i965:
Operation Precision error
-----------------------------------------------------
mod(-1.951171875, 1.9980468750) 0.0000000447
mod(121.57, 13.29) 0.0000023842
mod(3769.12, 321.99) 0.0000762939
mod(3769.12, 1321.99) 0.0001220703
mod(-987654.125, 123456.984375) 0.0160663128
mod( 987654.125, 123456.984375) 0.0312500000
This patch replaces the current lowering pass with a different one
(MOD_TO_FLOOR) that follows the recommended implementation in the GLSL
man pages:
mod(x,y) = x - y * floor(x/y)
This implementation eliminates the precision errors at the expense of
an additional add instruction on some systems. On systems that can do
negate with multiply-add in a single operation this new implementation
would come at no additional cost.

For code such as:
uint tmp1 = uint(in0);
uint tmp2 = -tmp1;
float out0 = float(tmp2);
We produce code like:
mov(8) g5<1>.xF -g9<4,4,1>.xUD
which does not produce correct results. This code produces the
results we would expect if tmp1 and tmp2 were signed integers
instead.
It seems that a similar problem was detected and addressed when
using negations with unsigned integers as part of condionals, but
it looks like the problem has a wider impact than that.
This patch fixes the problem by preventing copy-propagation of
negated UD registers in all scenarios, not only in conditionals.

If the ?: operator's condition is a constant value, and both branches
were pure expressions, we can just make the resulting value one or the
other.
Previously, we only did this if op[1] and op[2] were also constant
values - but there's no actual reason for that restriction.
No changes in shader-db, probably because we usually optimize this later
anyway. But it does make us generate less stupid code up front.

Paul originally had to reverse engineer these formulas based on the
description about how the sampler works. The description here is not
the easiest to follow - especially given that it's from the Sandybridge
era, when the hardware only did 4x multisampling.
Jordan and I recently found another part of the documentation where they
simply state that IMS dimensions must be adjusted by a set of formulas.
Quoting this section provides an easy to follow explanation for the
code, including 2x/4x/8x/16x.
