SPIRV-Tools
* Add enum for clspv reflection extended instruction set
* count it as non-semantic

* Update nbuilds to use grammars from SPIRV-Headers instead of
local duplicates
We need an analysis for OpenCL.DebugInfo.100 extension instructions such
as a map between function id and its DebugFunction. This commit add an
analysis for it.
Create a pass to instrument OpDebugPrintf instructions. This pass replaces all OpDebugPrintf instructions with instructions to write a record containing the string id and the all specified values into a special printf output buffer (if space allows). This pass is designed to support the printf validation in the Vulkan validation layers.
Fixes#3210
* Combine the extinst-name and extinst-output-base into one arg.
Some build systems such as Android blueprints require that the inputs
and outputs of generator scripts are all provided as arguments. These
two arguments to generate_language_headers.py are combined to form the
output path in the script. This change simply lets the user provide the
whole output path as an argument.
* Fix typo in build_defs.bzl and update Android.mk

* Use BUILD.gn from spirv-headers
The utils/generate_grammar_tables.py vendor-operand-kind-prefix
can now take a value of "...nil..." to signify the empty string.
That's needed because GN doesn't quote empty string arguments
correctly down into its action commands.

Most auto-generated files included by the SPIRV-Tools sources
do not have a proper newline at the end of file, creating a
hundred of compiler warnings, and even some build failures
when BUILD.gn is used for the Fuchsia build.
This fixes the issue by disabling the warning entirely.
* Handle id overflow in the ssa rewriter.
Remove LocalSSAElim pass at the same time. It does the same thing as the SSARewrite pass. Then even share almost all of the same code.
Fixes crbug.com/997246
The first pass applies the RelaxedPrecision decoration to all executable
instructions with float32 based type results. The second pass converts
all executable instructions with RelaxedPrecision result to the equivalent
float16 type, inserting converts where necessary.
Add the first steps to removing the AMD extension VK_AMD_shader_ballot.
Splitting up to make the PRs smaller.
Adding utilities to add capabilities and change the version of the
module.
Replaces the instructions:

OpGroupUMinNonUniformAMD = 5003
OpGroupSMinNonUniformAMD = 5004
OpGroupFMaxNonUniformAMD = 5005
OpGroupUMaxNonUniformAMD = 5006
OpGroupSMaxNonUniformAMD = 5007
and extentend instructions

Part of #2814
New files missing from BUILD.gn caused build failures in Chromium and
ANGLE:
remove_relaxed_precision_decoration_opportunity_finder.cpp
remove_relaxed_precision_decoration_opportunity_finder.h
We are no able to inline OpKill instructions into a continue construct.
See #2433. However, we have to be able to inline to correctly do
legalization. This commit creates a pass that will wrap OpKill
instructions into a function of its own. That way we are able to inline
the rest of the code.
The follow up to this will be to not inline any function that contains
an OpKill.
Fixes#2726
spirv-opt: Add --graphics-robust-access
Clamps access chain indices so they are always
in bounds.
Assumes:
- Logical addressing mode
- No runtime-array-descriptor-indexing
- No variable pointers
Adds stub code for clamping coordinate and samples
for OpImageTexelPointer.
Adds SinglePassRunAndFail optimizer test fixture.
Android.mk: add source/opt/graphics_robust_access_pass.cpp
Adds Constant::GetSignExtendedValue, Constant::GetZeroExtendedValue
This adds all the command-line tools from the CMakeLists.txt
file to the BUILD.gn used by Chromium and Fuchsia.
+ Add a convenient "all_spirv_tools" GN target to rebuild
all command-line tools at once.
+ "gn format" pass to fix a few minor issues in the file.
Tested on Chromium with the following procedure:
1) Have a clean Chromium checkout
2) # Update to upstream spirv-headers (otherwise spirv-tools build fails)
cd $CHROMIUM_SRC/third_party/spirv-headers/src &&
git remote add upstream https://github.com/KhronosGroup/SPIRV-Headers.git &&
git fetch upstream &&
git checkout upstream/master
3) # Update to upstream spirv-tools (Chromium is tracking older revision)
cd $CHROMIUM_SRC/third_party/SPIRV-Tools/src &&
git remote add upstream https://github.com/KhronosGroup/SPIRV-Tools.git &&
git fetch upstream &&
git checkout -tb check-patch upstream/master &&
git cherry-pick <patch>
3) # Rebuild Chromium and all SPIR-V tools for the host
cd $CHROMIUM_SRC/src &&
gn gen out/Linux --args 'use_goma = true' &&
ninja -C out/Linux -j1000 -l30 gn_all all_spirv_tools
4) Run the command-line tools, e.g.:
out/Linux/spirv-link --help
In order for the Fuchsia source tree to update its
version of SPIRV-Tools to a newer upstream, the
BUILD.gn needs to be slightly altered to take care
of the fact that it can be used with a different
GN //build set of rules and configs than the
Chromium one.
This is done by using |build_with_chromium|, already
defined by //build_overrides/build.gni, to guard
Chromium-specific statements.
+ Add a target to generate spirv-opt which is used by
Fuchsia to optimize shaders at build time for some
of its graphics libraries.
WebGPU requires certain variables to be initialized, whereas there are
known issues with using initializers in Vulkan. This PR is the first
of three implementing a pass to decompose initialized variables into
a variable declaration followed by a store. This has been broken up
into multiple PRs, because there 3 distinct cases that need to be
handled, which require separate implementations.
This first PR implements the basic infrastructure that is needed, and
handling of Function storage class variables. Private and Output will
be handled in future PRs.
This is part of resolving #2388
In WebGPU, the component operand 0xFFFFFFFF is forbidden, but in
Vulkan it is used to indicate a value is undefined. When converting to
WebGPU, 0xFFFFFFFF needs to converted to a legal value, though the
specific one does not matter, since it was used to indicate an
undefined entry in the original code. Choosing to use 0, since the
operands are required to be on [0, N-1], so 0 is guaranteed to always
be valid.
Fixes#2349
This pass tries to fix validation error due to a mismatch of storage classes
in instructions. There is no guarantee that all such error will be fixed,
and it is possible that in fixing these errors, it could lead to other
errors.
Fixes#2430.
Adds an optimization pass to remove usages of AtomicCounterMemory
bit. This bit is ignored in Vulkan environments and outright forbidden
in WebGPU ones.
Fixes#2242
The prior GoogleTest integration was incomplete and produced errors
when building with 'gn check' enabled. Fix this by scoping the test
integration to Chromium.
Fixes Issue #2382
Add a pass that looks for members of structs whose values do not affects
the output of the shader. Those members are then removed and just
treated like padding in the struct.
extensions_enum.inc is included from source/table.h.
So spvtools_core_enums_unified1 target should be in public_deps of
spvtools target.
This is for crbug.com/931596
* Fixes#2358. Added to the reducer the ability to remove a function that is not directly called. Factored out some code from the optimizer to help with this.
