* 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.
Fixes#3120
* Clone opencl.debuginfo.100 grammar from debuginfo grammar
Update version number to 200 revision 2
* Apply content from OpenCL.DebugInfo.100 extension text
* Rename grammar file
* Support OpenCL.DebugInfo.100 extended instructions
Add support for prefixing operand type names, to disambiguate
them between different instruction sets.
* Add tests for OpenCL.DebugInfo.100
* Support lookup of OpenCL.DebugInfo.100 extinst
* Add tests for enum values
* Recognize 2017-2019 as copyright date range
* Android.mk: support OpenCL.DebugInfo.100 extended instruction set
Also, stop generating core instruction tables for non-unified1 versions
of the grammar.
* Imported entity operand type is concrete
* Bazel: Suppoort OpenCL.DebugInfo.100
* BUILD.gn: Support OpenCL.DebugInfo.100
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:
OpGroupIAddNonUniformAMD = 5000
OpGroupFAddNonUniformAMD = 5001
OpGroupFMinNonUniformAMD = 5002
OpGroupUMinNonUniformAMD = 5003
OpGroupSMinNonUniformAMD = 5004
OpGroupFMaxNonUniformAMD = 5005
OpGroupUMaxNonUniformAMD = 5006
OpGroupSMaxNonUniformAMD = 5007
and extentend instructions
WriteInvocationAMD = 3
MbcntAMD = 4
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.
These are bookend passes designed to help preserve line information
across passes which delete, move and clone instructions. The propagation
pass attaches a debug line instruction to every instruction based on
SPIR-V line propagation rules. It should be performed before optimization.
The redundant line elimination pass eliminates all line instructions
which match the previous line instruction. This pass should be performed
at the end of optimization to reduce physical SPIR-V file size.
Fixes#2027.
* Add base and core bindless validation instrumentation classes
* Fix formatting.
* Few more formatting fixes
* Fix build failure
* More build fixes
* Need to call non-const functions in order.
Specifically, these are functions which call TakeNextId(). These need to
be called in a specific order to guarantee that tests which do exact
compares will work across all platforms. c++ pretty much does not
guarantee order of evaluation of operands, so any such functions need to
be called separately in individual statements to guarantee order.
* More ordering.
* And more ordering.
* And more formatting.
* Attempt to fix NDK build
* Another attempt to address NDK build problem.
* One more attempt at NDK build failure
* Add instrument.hpp to BUILD.gn
* Some name improvement in instrument.hpp
* Change all types in instrument.hpp to int.
* Improve documentation in instrument.hpp
* Format fixes
* Comment clean up in instrument.hpp
* imageInst -> image_inst
* Fix GetLabel() issue.
* Create structed cfg analysis.
There are lots of optimization that have to traverse the CFG in a
structured order just because it wants to know which constructs a
basic block in contained in. This adds extra complexity to these
optimizations, for causes too much refactoring of older optimizations.
To help with this problem, I have written an analysis that can give this
information.
* Identify branches breaking from loops.
Dead branch elimination does a search for a conditional branch to the
end of the current selection construct. This search assumes that the
only way to leave the construct is through the merge node. But that is
not true. The code can jump to the merge node of a loop that contains
the construct.
The search needs to take this into consideration.
This splits the spvtools_config into a public and private part to avoid
leaking internal bits to dependents. A new target is added for the
public headers so that "gn check" works for dependents.
Also formats test/fuzzers/BUILD.gn
This reverts commit 3cddf9131d.
This breaks the Chrome roll:
ERROR Unresolved dependencies.
//third_party/SPIRV-Tools/src/test/fuzzers:fuzzer_config(//build/toolchain/linux:clang_x64)
needs //third_party/SPIRV-Tools/src:spvtools_config(//build/toolchain/linux:clang_x64)
GN gen failed: 1
This splits the spvtools_config into a public and private part to avoid
leaking internal bits to dependents. A new target is added for the
public headers so that "gn check" works for dependents.
* Split constant opcode validation out of idUsage and into
validate_constants.cpp
* minor style fixes
* reduced duplication
* fixed an issue with array sizing
The code in source/message was only used in a single set of tests to
format the output results. This CL changes the test to verify the
message instead of all the error values and removes the source/message
code.
* Moved function opcode validation out of idUsage and into new files
* minor style changes
* General opcode checking is in validate_function.cpp
* Execution limitation checking is in
validate_execution_limitations.cpp
* Execution limitations was split into a new pass as it requires other
validation to register those limitations first.
* Moved type instruction validation out of validation idUsage into a new
file
* Consolidate type unique pass into new file
* Removed one bad test
* Reworked validation ordering
1.
BUILD.gn: Don't use the extra Chromium clang warnings
Also removes the unused .gn secondary_sources.
2.
Move fuzzers in test/ instead of testing/
This frees up testing/ to be the git subtree of Chromium's src/testing/
that contains test.gni, gtest, gmock and libfuzzer
3.
DEPS: get the whole testing/ subtree of Chromium
4.
BUILD.gn: Simplify the standalone gtest targets
These targets definitions are inspired from ANGLE's and add a variable
that is the path of the googletest directory so that it can be made
overridable in future commits.
6.
BUILD.gn: Add overridable variables for deps dirs
This avoids hardcoded paths to dependencies that make it hard to
integrate SPIRV-Tools in other GN projects.
* Refactored the Memory class of instructions in the spec out Id
validation and into a new pass
* Tests unmodified
* some minor disassembly changes
* minor style changes
The SPIRV-Tools target doesn't build anything, it just depends on the other libraries. As such, there is no static_library generated and this should be a group() instead.
