spirv-fuzz: Fixes to pass management (#4011) 2020-11-04 10:45:53 +00:00

spirv-fuzz: Add support for reining in rogue fuzzer passes (#3987) 
Adds some functions that allow a fuzzer pass to check whether it is
spiralling out of control and exit early.  The fuzzer pass for adding
bit instruction synonyms now uses this.  Also make many methods in
FuzzerContext const.

spirv-fuzz: Fix bug related to transformation applicability (#3990) 
This PR fixes a bug related to the transformation applicability.
When the OpNot case was implemented, its opcode was not
added to the list of supported bit instructions in IsApplicable.
So, the changes made are the following.

- Add OpNot to the list of supported bit instructions.
- Update the tests.

CMake: Add SPIRV_TOOLS_BUILD_STATIC flag (#3910) 
If enabled the following targets will be created:

* `${SPIRV_TOOLS}-static` - `STATIC` library. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.
* `${SPIRV_TOOLS}`        - will alias to one of above, based on BUILD_SHARED_LIBS.

If disabled the following targets will be created:

* `${SPIRV_TOOLS}`        - either `STATIC` or `SHARED` based on the new `SPIRV_TOOLS_LIBRARY_TYPE` flag. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.

Defaults to `ON`, matching existing build behavior.

This flag can be used by package maintainers to ensure that all libraries are built as shared objects.

spirv-fuzz: Add expand vector reduction transformation (#3869) 
The following implementations are introduced:

- Transformation and fuzzer pass for expanding vector reduction.
- Unit tests to cover the instructions with different vector sizes.

Fixes #3768.

spirv-fuzz: Avoid creating blocks without parents (#3908) 
The validity check during fuzzing and in unit tests is strengthened to
require that every block has its enclosing function as its parent.
TransformationMergeFunctionReturns is fixed so that it ensures parents
are set appropriately.
