* tools: refactorize tools flags parsing.
Each SPIR-V tool was handing their own flag parsing. This PR
adds a new flag parsing utility that should be flexible enough
for our usage, but generic enough so it can be shared across tools while
remaining simple to use.
* cfg: replace cfg option parsing with the new one.
* change spirv-dis parsing + title + summary
* clang format
* flags: fix static init fiasco & remove help
Static initialization order is important, and was
working just by sheer luck.
Also removing the help generation tooling. It's less flexible than the
hand-written string, and making it as-good and as-flexible brings too
much complexity.
* review feedback
In a Chromium build environment on Windows git is supplied by
depot_tools as git.bat. This was causing build errors on Windows that
are most easily reproduced with this command:
gn gen out\default && gn clean out\default && ninja -C out\default spirv-as
The errors included:
[12:55:40][ERROR ] Failed to run "['git', 'tag', '--sort=-v:refname']" in "C:\src\chromium\src\third_party\vulkan-deps\spirv-tools\src": [WinError 2] The system cannot find the file specified
[12:55:40][WARNING ] Could not deduce latest release version from history.
This is because 'git' does not resolve to git.bat unless shell=True is
passed to subprocess.Popen. This change passes shell=True but only on
Windows which resolves these errors.
Before, we did set cxx version to c++17 using COPTS in our bazel files.
This was wrong, and part of the dependencies were then built with the
default standard version. This was not an issue until we moved to c++17.
Then, we decided to use the bazel --cxxopt=-std=c++17, but this was only
valid for nix platforms.
The last option left is to ask the user to specify the standard
when building using bazel.
Adding a new type instruction required making the same change in two
places.
Also remove IsCompileTimeConstantInst that was used in a single place
and replace its use by an expression that better conveys the intent.

This commit adds a C++ wrapper above the current spvBinaryParse
function. I tried to match it 1:1, except for 2 things:
- std::function<>& are used. No more function pointers, allowing
context capture.
- spv_result_t replaced with a boolean, to match other C++ apis.
Callbacks still return a spv_result_t because the underlying implem
relies on that. The convertion from spv_result_t to boolean is only done
at the boundary.

* Update fuzz tests to not use invalid combinations of LoopMerge + BranchConditional
New IDs were selected to make clear the transformation being done here, instead
of reordering all IDs in between or refactoring the SPIR-V in the test.
* spirv-val: Conditional Branch without an exit is invalid in loop header
From 2.16.2, for CFG:
Selections must be structured. That is, an OpSelectionMerge
instruction is required to precede:
- an OpSwitch instruction
- an OpBranchConditional instruction that has different True Label
and False Label operands where neither are declared merge blocks
or Continue Targets.
When the build is done on a shallow repo, or on a non-git copy,
the version script failed. We should not hard fail, but generate
a "version" (unknown).
Sample outputs:
with git history:
`"v2023.2-dev", "SPIRV-Tools v2023.2-dev v2022.4-87-g53541064"`
with shallow clone:
`"unknown_version", "SPIRV-Tools unknown_version d8759a140bc65811332d5f91f3b08febadd5a21d"`
not a git repo:
`"unknown_version", "SPIRV-Tools unknown_version unknown_hash, 2023-02-02T16:25:48.077995"`
* Fix null pointer in FoldInsertWithConstants.
Struct types are not supported in constant folding yet.
* Added 'Test case 16' to fold_test.
Tests OpCompositeInsert not to be folded on a struct type.
Contributes to https://github.com/KhronosGroup/glslang/issues/2439
* When OpTypeStruct is used in Vulkan env and its last member
is a RuntimeArray, check if the struct is decorated with
Block or BufferBlock, as required by VUID-...-04680.
-Make more use of InstructionBuilder instruction helper methods
-Use MakeUnique<>() rather than new
-Add InstrumentPass::GenReadFunctionCall() which optimizes function
calls in a loop with constant arguments and no side effects.
This is a prepatory change for future work on the instrumentation
code which will add more generated functions.
This commit changes the way bazel chooses which version to build.
Before, we had a COPT set to -std=c++17, which is analogous to the cmake
way.
However, googletest decided to follow abseil, meaning this is *not*
recommended at all, and causes a mixed-standard build.
From https://github.com/abseil/abseil-cpp/blob/master/FAQ.md#how-to-i-set-the-c-dialect-used-to-build-abseil
we have 3 options to define the standard. Using a bazelrc is what I
believe to be the simplest, as it "fixes" the repo standard.

The CHANGES file was an alternative source of truth that was trying
to duplicate/replace the git history truth.
This allow us to change the way we handle releases so we don't have to make
sure our CHANGES PR are linked to the tag and tested PR, simplifying the
process.
This should help with avoiding mistakes such as the one that happened under #4958.

Kokoro clones repos with a different user used to run the build steps,
meaning if some git command must be run at build time, they will fail
because of this dubious ownership issue.
Running some git commands makes only sense with history, so changing
checkout depth so we can run them and get the true result.
This is a known Kororo issue.
Fixing this is required to generate the version file using git history.

* build: move from c++11 to c++17
Moving from cpp 11 to cpp 17 will allow us to use modern features like
filesystem support, optional, any, execution policies and improved
templates.
