Lioncash b7cd5d742e shader_bytecode: Make use of [[nodiscard]] where applicable
Ensures that all queried values are made use of.

ReinUsesLisp 44b552be71 shader/arithmetic: Implement FCMP immediate + register variant
Trivially add the encoding for this.

ReinUsesLisp 39ab33ee1c shader/half_set: Implement HSET2_IMM
Add HSET2_IMM. Due to the complexity of the encoding avoid using
BitField unions and read the relevant bits from the code itself.
This is less error prone.

ReinUsesLisp 4e57f9d5cf shader_ir: Separate float-point comparisons in ordered and unordered
This allows us to use native SPIR-V instructions without having to
manually check for NAN.

ReinUsesLisp c788f9c0bd shader/arithmetic_integer: Implement IADD.X
IADD.X takes the carry flag and adds it to the result. This is generally
used to emulate 64-bit operations with 32-bit registers.

decode/arithmetic_half: Fix HADD2 and HMUL2 absolute and negation bits

ReinUsesLisp dbaebd8582 decode/arithmetic_half: Fix HADD2 and HMUL2 absolute and negation bits
The encoding for negation and absolute value was wrong.
Extracting is now done manually. Similar instructions having different
encodings is the rule, not the exception. To keep sanity and readability
I preferred to extract the desired bit manually.

This is implemented against nxas:
8dbc389957/table.h (L68)

That is itself tested against nvdisasm (Nvidia's official disassembler).

Lioncash 1c340c6efa CMakeLists: Specify -Wextra on linux builds
Allows reporting more cases where logic errors may exist, such as
implicit fallthrough cases, etc.

We currently ignore unused parameters, since we currently have many
cases where this is intentional (virtual interfaces).

While we're at it, we can also tidy up any existing code that causes
warnings. This also uncovered a few bugs as well.

ReinUsesLisp 76f178ba6e shader/video: Partially implement VMNMX
Implements the common usages for VMNMX. Inputs with a different size
than 32 bits are not supported and sign mismatches aren't supported
either.

VMNMX works as follows:
It grabs Ra and Rb and applies a maximum/minimum on them (this is
defined by .MX), having in mind the input sign. This result can then be
saturated. After the intermediate result is calculated, it applies
another operation on it using Rc. These operations are merges,
accumulations or another min/max pass.

This instruction allows to implement with a more flexible approach GCN's
min3 and max3 instructions (for instance).

ReinUsesLisp 3185245845 shader/memory: Implement RED.E.ADD
Implements a reduction operation. It's an atomic operation that doesn't
return a value.

This commit introduces another primitive because some shading languages
might have a primitive for reduction operations.

ReinUsesLisp bf9a822b87 shader/decode: Fix constant buffer offsets
Some instances were using cbuf34.offset instead of cbuf34.GetOffset().
This returned the an invalid offset. Address those instances and rename
offset to "shifted_offset" to avoid future bugs.

It's the same as the variant that was implemented, but it takes the
operands from another source.

second.

ReinUsesLisp d95d4ac843 shader/memory: Implement ATOM.ADD
ATOM operates atomically on global memory. For now only add ATOM.ADD
since that's what was found in commercial games.

This asserts for ATOM.ADD.S32 (handling the others as unimplemented),
although ATOM.ADD.U32 shouldn't be any different.

This change forces us to change the default type on SPIR-V storage
buffers from float to uint. We could also alias the buffers, but it's
simpler for now to just use uint. While we are at it, abstract the code
to avoid repetition.

This commit fixes an issue where not all 4 results of tld4 were being

It also implements the bindless variant.

Lioncash 7fdf991097 shader_bytecode: Make Matcher constexpr capable
Greatly shrinks the amount of generated code for GetDecodeTable().

Collapses an assembly output of 9000+ lines down to ~3621 with Clang,
and 6513 down to ~2616 with GCC, given it's now allowed to construct all
the entries as a sequence of constant data.
