From page 140 (page 147 of the PDF) of the GLSL ES 3.10 v.4 spec:
" 9.2 Matching of Qualifiers
The following tables summarize the requirements for matching of
qualifiers. It applies whenever there are two or more matching
variables in a shader interface.
Notes:
1. Yes means the qualifiers must match.
...
9.2.1 Linked Shaders
| Qualifier | Qualifier | in/out | Default | uniform | buffer|
| Class | | | Uniforms | Block | Block |
...
| Layout | binding | N/A | Yes | Yes | Yes |"
From page 93 (page 110 of the PDF) of the GL 4.2 (Core Profile) spec:
" 2.11.7 Uniform Variables
...
Uniform Blocks
...
When a named uniform block is declared by multiple shaders in a
program, it must be declared identically in each shader. The
uniforms within the block must be declared with the same names and
types, and in the same order. If a program contains multiple
shaders with different declarations for the same named uniform
block differs between shader, the program will fail to link."
From page 129 (page 150 of the PDF) of the GL 4.3 (Core Profile) spec:
" 7.8 Shader Buffer Variables and Shader Storage Blocks
...
When a named shader storage block is declared by multiple shaders
in a program, it must be declared identically in each shader. The
buffer variables within the block must be declared with the same
names, types, qualification, and declaration order. If a program
contains multiple shaders with different declarations for the same
named shader storage block, the program will fail to link."
Therefore, if the binding qualifier differs between two linked Uniform
or Shader Storage Blocks of the same name, a link error should happen.
This patch will make that a link error will be reported on a program
like this:
"# VS
layout(binding = 1) Block {
vec4 color;
} uni_block1;
...
# FS
layout(binding = 2) Block {
vec4 color;
} uni_block2;
..."

While it's legal to have an active blocks count > 0 on link failure.
Unless we actually assign memory for the blocks array we can end up
segfaulting in calls such as glUniformBlockBinding().
To avoid having to NULL check these api calls we simply reset the
block count to 0 if the array was not created.

The checks were only looking at the first byte, while the intention
seems to be to check if the whole sha1 is zero. This prevented all
shaders with first byte zero in their sha1 from being saved.
This shaves around a second from Deus Ex load time on a hot cache.

Even though the programs themselves stay in cache and are loaded, the
shader keys can be evicted separately. If that happens, unnecessary
compiles are caused that waste time, and no matter how many times the
program is re-run, performance never recovers to the levels of first
hot cache run. To deal with this, we need to refresh the shader keys
of shaders that were recompiled.
An easy way to currently observe this is running Deux Ex, then piglit
and Deux Ex again, or deleting just the cache index. The later is
causing over a minute of lost time on all later Deux Ex runs, with this
patch it returns to normal after 1 run.

Instead of using a directory, hash the timestamps into the cache keys
themselves. Since there is no more timestamp directory, there is no more
need for deleting the cache of other mesa versions and we rely on
eviction to clean up the old cache entries. This solves the problem of
using several incarnations of disk_cache at the same time, where one
deletes a directory belonging to the other, like when both OpenGL and
gallium nine are used simultaneously (or several different mesa
installations).

Previously each time we saw a variable we just created a duplicate
entry in the list. This is particularly bad for loops were we add
everything twice, and then throw nested loops into the mix and the
list was growing expoentially.
This stops the glsl-vs-unroll-explosion test which has 16 nested
loops from reaching the tests mem usage limit in this pass. The
test now hits the mem limit in opt_copy_propagation_elements()
instead.
I suspect this was also part of the reason this pass can be so
slow with some shaders.

The NIR story on conversion opcodes is a mess. We've had way too many
of them, naming is inconsistent, and which ones have explicit sizes was
sort-of random. This commit re-organizes things and makes them all
consistent:
- All non-bool conversion opcodes now have the explicit size in the
destination and are named <src_type>2<dst_type><size>.
- Integer <-> integer conversion opcodes now only come in i2i and u2u
forms (i2u and u2i have been removed) since the only difference
between the different integer conversions is whether or not they
sign-extend when up-converting.
- Boolean conversion opcodes all have the explicit size on the bool and
are named <src_type>2<dst_type>.
Making things consistent also allows nir_type_conversion_op to be moved
to nir_opcodes.c and auto-generated using mako. This will make adding
int8, int16, and float16 versions much easier when the time comes.
