Avoids redundantly searching the whome module when locating an
instruction from its descriptor - instead, only the block containing
the instruction needs to be searched.
The performance of spirv-fuzz is sometimes poor due to analyses being
conservatively invalidated. This can lead to quadratic time algorithms
when a fuzzer pass applies O(N) transformations, and where every
transformation e.g. depends on def-use analysis and invalidates
def-use analysis (because building def-use analysis is O(N)).
This change avoids invalidating analyses for certain transformations.
The fuzzer library depended on CLIMessageConsumer, due to its explicit
use in a function. This change removes that dependency so that,
instead, a message consumer parameter is passed.
* Use standard function to get stdin to binary mode.
The fisrt implementation to try to change stdin to binary mode is not
protable. Using freopen has a lot of implementation defined behaviour,
and the code relied on that working.
Looking into the MSVC documentation, I do not see a protable way of
doing this. I've implemented a Windows specific method and do nothing
for other systems. In general, UNIX based systems do make a distinction
between text and binary files, so nothing needs to be done for them.
Fixes#2518
* Split ReadFile into two different functions.
We want to remove the flag parameter. So the original function has been
replaced with ReadBinaryFile and ReadTextFile. This should make the
code more readable.
* Change name of CorrectlyReadFile to avoid confusion.
Fix URL to the `OpenCL.DebugInfo.100` grammar file, which moved from `SPIRV-Tools` to `SPIRV-Headers`.
Add a `go.mod` and `go.sum` file.
Go has now fully migrated to using modules, and relative imports no longer work.
Fixup all the relative imports to use a fully qualified path based on the module name.
Fix the `.exe` executable extension on windows.
Update the generated grammar files.
Update the `README.md` with more information.
Disable generation of the log file. Seems to end up in the workspaceDir on windows, not the executable path
This allows the GPU-AV layer to differentiate between errors with
uniform buffers versus storage buffers and map these to the relevant
VUIDs.
This is a resubmit of a previously reverted commit. The revert was
done as someone erroneously attempted to build the latest validation
layers with a TOT spirv-tools. The validation layers must be built with
their known-good glslang and its known-good spirv-tools and spirv-headers.
* Mark module as modified if convert-to-half removes decorations.
If the convert-to-half pass does not change the body of the function,
but removes decorations, it returns that nothing changed. This is
incorrect, and will be fixed.

* Update comment for RemoveDecorationsFrom
The existing spirv-opt `DebugInfoManager::AddDebugValueForDecl()` sets
the scope and line info of the new added DebugValue using the scope and
line of DebugDeclare. This is wrong because only a single DebugDeclare
must exist under a scope while we have to add DebugValue for all the
places where the variable's value is updated. Therefore, we have to set
the scope and line of DebugValue based on the places of the variable
updates.
This bug makes

fail. This commit fixes the bug.
* Validate SPV_KHR_workgroup_memory_explicit_layout
* Check if SPIR-V is at least 1.4 to use the extension.
* Check if either only Workgroup Blocks or only Workgroup non-Blocks
are used.
* Check that if more than one Workgroup Block is used, variables are
decorated with Aliased.
* Check layout decorations for Workgroup Blocks.
* Implicitly use main capability if the ...8BitAccess or
...16BitAccess are used.
* Allow 8-bit and 16-bit types when ...8BitAccess and ...16BitAccess
are used respectively.
* Update SPIRV-Headers dependency
Bump it to include SPV_KHR_workgroup_memory_explicit_layout.
* Add option to validate Workgroup blocks with scalar layout
Validate the equivalent of scalarBlockLayout for Workgroup storage
class Block variables from SPV_KHR_workgroup_memory_explicit_layout.
Add option to the API and command line tool.
This patch supports new Intel extensions added via
https://github.com/KhronosGroup/SPIRV-Headers/pull/176
SPV_INTEL_fooat_controls2 requires extra support to add
two new operand types:
SPV_OPERAND_TYPE_FPDENORM_MODE
SPV_OPERAND_TYPE_FPOPERATION_MODE
* Work around GCC-9 warning treated as error
```
../source/opt/instruction.h:101:23: error: '*((void*)& operand +32)' may be used uninitialized in this function [-Werror=maybe-uninitialized]
101 | uint64_t result = uint64_t(words[0]);
```
* Migrate all Kokoro build scripts over to use the docker VM image
Required updating the NDK SDK and build scripts, as well as the check_copyright for handling 2021.
