Autogenerating the following code:
- extension enum
- extension-to-string
- string-to-extension
- capability-to-string
Capability mapping table will not compile if incomplete.
TODO: Use "spirv-latest-version.h" instead of 1.1.
Added function to generate capability tables for tests.
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.
Default-constructed Pass/PassManager will have a MessageConsumer
which ignores all messages. SetMessageConsumer() should be called
to supply a meaningful MessageConsumer.
De-duplicate constants and unifies the uses of constants for a SPIR-V
module. If two constants are defined exactly the same, only one of them
will be kept and all the uses of the removed constant will be redirected
to the kept one.
This pass handles normal constants (defined with
OpConstant{|True|False|Composite}), some spec constants (those defined
with OpSpecConstant{Op|Composite}) and null constants (defined with
OpConstantNull).
There are several cases not handled by this pass:
1) If there are decorations for the result id of a constant defining
instruction, that instruction will not be processed. This means the
instruction won't be used to replace other instructions and other
instructions won't be used to replace it either.
2) This pass does not unify null constants (defined with
OpConstantNull instruction) with their equivalent zero-valued normal
constants (defined with OpConstant{|False|Composite} with zero as the
operand values or component values).
For the spec constants defined by OpSpecConstantOp and
OpSpecContantComposite, if all of their operands are constants with
determined values (normal constants whose values are fixed), calculate
the correct values of the spec constants and re-define them as normal
constants.
In short, this pass replaces all the spec constants defined by
OpSpecContantOp and OpSpecConstantComposite with normal constants when
possible. So far not all valid operations of OpSpecConstantOp are
supported, we have several constriction here:
1) Only 32-bit integer and boolean (both scalar and vector) are
supported for any arithmetic operations. Integers in other width (like
64-bit) are not supported.
2) OpSConvert, OpFConvert, OpQuantizeToF16, and all the
operations under Kernel capability, are not supported.
3) OpCompositeInsert is not supported.
Note that this pass does not unify normal constants. This means it is
possible to have new generatd constants defining the same values.
This is experimental, and has not tests.
It's been used to debug validation of structured control flow.
- Has a legend describing special arcs to merge blocks and continue
targets.
- Labels the function entry block, with the Id of the function.
Add a pass to freeze spec constants to their default values. This pass does
not fold the frozen spec constants and does not handle SpecConstantOp
instructions and SpecConstantComposite instructions.
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.
