If the variable_pointer extension is used:
* OpLoad's pointer argument may be the result of any of the following:
* OpSelect
* OpPhi
* OpFunctionCall
* OpPtrAccessChain
* OpCopyObject
* OpLoad
* OpConstantNull
* Return value of a function may be a pointer.
* It is valid to use a pointer as the return value of a function.
* OpStore should allow a variable pointer argument.
Add --flatten-decorations to spirv-opt
Flattens decoration groups. That is, replace OpDecorationGroup
and its uses in OpGroupDecorate and OpGroupMemberDecorate with
ordinary OpDecorate and OpMemberDecorate instructions.

Exercises our public APIs more, and avoid including most
internal headers. It also shortens the processing part
of the code, but does make adding passes look more complex.
Doing this exposed issue 611, a bug in spvtools::Optimizer.
The spvtools::Optimizer::Run method should also write the output binary
if optimization succeeds without changes but the output binary vector
does not have exactly the same contents as the input binary.
We have to check both the base pointer of the storage and the size of
the vector
Added a test for this too.

Supported in assembler, disassembler, and binary parser.
The validator does not check SPV_AMD_gcn_shader validation rules
beyond parsing the extension.
Adds generic support for generating instruction tables for vendor
extensions.
Adds generic support for extensions the validator should recognize
(but not check) but which aren't derived from the SPIR-V core
grammar file.
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/594
The SPIR-V core grammar file in a recent SPIRV-Headers
applied the fix from Rev 7 of SPV_KHR_16bit_storage:
FPRoundingMode enums are now enabled by the capabilities
introduced by that extension.
Update the SPIRV-Tools tests accordingly.
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.
Known extensions are saved in validation state. Unknown extension
produce a dignostic message, but do not fail the validation.
Moved extension definitions to their own file.
The assembler assigns ID numbers sequentially, so it's confusing
to have a %1 in the source assembly when it isn't the first mentioned
ID. Rewrite the ID names to avoid this situation in a few cases.
From the SPIR-V Spec 2.16.1:
A function declaration (an OpFunction with no basic blocks), must have
a Linkage Attributes Decoration with the Import Linkage Type.
A function definition (an OpFunction with basic blocks) cannot be
decorated with the Import Linkage Type.
- validation_state.cpp uses functions from opcode.h instead of in-place
switches which need to be updated.
- added new spirv 1.1 type declaration opcodes to a 'is op type
declaration' switch in opcode.cpp.
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.
