Fixes#937
Stop std140/430 validation when runtime array is encountered.
Check for standard uniform/storage buffer layout instead of std140/430.
Added validator command line switch to skip block layout checking.
Validate structs decorated as Block/BufferBlock only when they
are used as variable with storage class of uniform or push
constant.
Expose --relax-block-layout to command line.
dneto0 modification:
- Use integer arithmetic instead of floor.
Add SPV_ENV_WEBGPU_0 for work-in-progress WebGPU.
val: Disallow OpUndef in WebGPU env
Silence unused variable warnings when !defined(SPIRV_EFFCE)
Limit visibility of validate_instruction.cpp's symbols
Only InstructionPass needs to be visible so all other functions are put
in an anonymous namespace inside the libspirv namespace.
[val] Add extra context to error messages.
This CL extends the error messages produced by the validator to output the
disassembly of the errored line.
The validation_id messages have also been updated to print the line number of
the error instead of the word number. Note, the error number is from the start
of the SPIR-V, it does not include any headers printed in the disassembled code.
Fixes#670, #1581
The default target is SPIR-V 1.3.
For example, spirv-as will generate a SPIR-V 1.3 binary by default.
Use command line option "--target-env spv1.0" if you want to make a SPIR-V
1.0 binary or validate against SPIR-V 1.0 rules.
Example:
# Generate a SPIR-V 1.0 binary instead of SPIR-V 1.3
spirv-as --target-env spv1.0 a.spvasm -o a.spv
spirv-as --target-env vulkan1.0 a.spvasm -o a.spv
# Validate as SPIR-V 1.0.
spirv-val --target-env spv1.0 a.spv
# Validate as Vulkan 1.0
spirv-val --target-env vulkan1.0 a.spv
In HLSL structured buffer legalization, pointer to pointer types
are emitted to indicate a structured buffer variable should be
treated as an alias of some other variable. We need an option to
relax the check of pointer types in logical addressing mode to
catch other validation errors.
There are a number of users of spriv-opt that are hitting errors
because of stores with different types. In general, this is wrong, but,
in these cases, the types are the exact same except for decorations.
The options is "--relax-store-struct", and it can be used with the
validator or the optimizer.
We assume that if layout information is missing it is consistent. For
example if one struct has a offset of one of its members, and the other
one does not, we will still consider them as being layout compatible.
The problem will be if both struct has and offset decoration for
corresponding members, and the offset are different.
The limit for the number of struct members is parameterized using
command line options.
Add --max-struct-depth command line option.
Add --max-switch-branches command line option.
Add --max-function-args command line option.
Add --max-control-flow-nesting-depth option.
Add --max-access-chain-indexes option.
Add a high level version number for SPIRV-Tools, beginning
with v2016.0-dev. The README describes the format of the
version number.
The high level version number is extracted from the CHANGES
file. That works around:
- stale-bait for when we don't add tags to the repository
- our inability to add tags to the repository
Option --version causes spirv-as, spirv-dis, and spirv-val to
show the high level version number.
Add spvSoftwareVersionString to return the C-string for
the high level version number.
Add spvSoftwareVersionDetailsString() so that clients can get
more information if they want to.
Also allows us to clean up the uses in the tool executables files,
so now only one file includes build-version.inc.
Move the update-build-version logic to the only
CMakeLists file that needs it.
The update build version script takes a new argument
to name the output file.
Add test for named-barrier instructions and capability.
Add spv_target_env as an optional argument to CompileSuccessfully() and
CompileFailure(). Currently defaults to UNIVERSAL_1_0, though that
could change in the future.
Make spv_context a local variable in test methods instead of a
TextToBinaryTestBase member. Introduce ScopedContext to make temp
contexts easier.
For fulfilling this purpose, the |opcode| field in the
|spv_parsed_instruction_t| struct is changed to of type uint16_t.
Also add functions to query the information of a given SPIR-V
target environment.
Users always want to run all the checks. The spv_validate_options_t
mechanism, which provides little benefits to users, complicates the
internal implementation and also makes the tests exercise different
paths as users do.
Right now the tests are more like integration tests instead of
unit tests, which should be our next refactoring aim.
Now we have public headers arranged as follows:
$SPIRV_TOOLS_ROOT/include/spirv-tools/libspirv.h
$SPIRV_TOOLS_ROOT/include/spirv/spirv.h
$SPIRV_TOOLS_ROOT/include/spirv/GLSL.std.450.h
$SPIRV_TOOLS_ROOT/include/spirv/OpenCL.std.h
A project should use -I$SPIRV_TOOLS_ROOT/include
and then #include "spirv-tools/libspirv.h"
The headers from the SPIR-V Registry can be accessed as "spirv/spirv."
for example.
The install target should also install the headers from the SPIR-V
Registry. The libspirv.h header is broken otherwise.
The SPIRV-Tools library depends on the headers from the SPIR-V Registry.
The util/bitutils.h and util/hex_float.h are pulled into the internal
source tree. Those are not part of the public API to SPIRV-Tools.
Previously the opcode table is declared as an global array and we
have spvOpcodeTableInitialize() modifying it. That can result in
race condition. Now spvOpcodeTabelGet() copies the whole underlying
array.
Replaced uint64_t with size_t in the places that make sense and
added spv_const_binary{,_t} to allow the interface to accept non
modifiable spirv where appropriate.
Note that we are more strict than Google style for one aspect:
pointer/reference indicators are adjacent to their types, not
their variables.
