This patch adds the optional FPEncoding operand that can be added to OpTypeFloat.
At the moment there is no usable operand, so support is limited to adding the entry.

With --nested-indent, the SPIR-V blocks are nested according to the
structured control flow. Each OpLabel is nested that much with the
contents of the block nested a little more. The blocks are separated by
a blank line for better visualization.
With --reorder-blocks, the SPIR-V blocks are reordered according to the
structured control flow. This is particularly useful with
--nested-indent.
Note that with --nested-indent, the disassembly does not exactly show
the binary as-is, and the instructions may be reordered.
In contrast to the C API, the C++ API did not have symbol visibility
specified. An application using the C++ API would fail to link
against a shared SPIRV-Tools library built with `-fvisibility=hidden`.
Mark all classes in the public `.hpp` files with `SPIRV_TOOLS_EXPORT`.
Add `SPIRV_TOOLS_LOCAL` to hide nested structs containing
implementation details.

The optimizer is able to preserve the interface variables of the
shaders, but that feature has not been exposed to the command line
tool.
This commit adds an option `--preserve-interface` to spirv-opt that will
cause all calls to ADCE to leave the input and output variables, even if
the variable is unused. It will apply regardless of where the option
appears on the command line.

* SPV_KHR_cooperative_matrix
* Update DEPS with headers
* Update according to review recommendations
* Bugfix and formatting
* Formatting missed or damaged by VS2022
This commit adds a C++ wrapper above the current spvBinaryParse
function. I tried to match it 1:1, except for 2 things:
- std::function<>& are used. No more function pointers, allowing
context capture.
- spv_result_t replaced with a boolean, to match other C++ apis.
Callbacks still return a spv_result_t because the underlying implem
relies on that. The convertion from spv_result_t to boolean is only done
at the boundary.

The always-friendly messages make it harder to debug when the
disassembly is later generated without friendly names.
Additionally, the friendly-name-mapper is slow. Disabling it improves
performance of an ANGLE test that creates numerous shaders by ~5%.
* Basic support for SPIR-V 1.6
* Update SPIRV-Headers deps
* Add new environment enum for SPIR-V 1.6
* Make default environment 1.6 for most tools
* Update tests
* Disallow conditional branch with duplicate labels
* Disallow Dim=Buffer with sampled images
* Do not require the non-semantic extension after SPIR-V 1.5
To allow querying the range of target environments (to ensure that a
target environment value is within the valid range of the associated
enum), this change adds a maximum value to the spv_target_env
enumeration.
Includes:
- Shift to use of spirv-header extinst.nonsemantic.shader grammar.json
- Remove extinst.nonsemantic.vulkan.debuginfo.100.grammar.json
- Enable all optimizations for Shader.DebugInfo
Also fixes scalar replacement to only insert DebugValue after all
OpVariables. This is not necessary for OpenCL.DebugInfo, but it is
for Shader.DebugInfo.
Likewise, fixes Private-to-Local to insert DebugDeclare after all
OpVariables.
Also fixes inlining to handle FunctionDefinition which can show up
after first block if early return processing happens.

Allow LocalSizeId as a way of sizing compute workgroups where the
environment allows it. A command-line switch is also added to force
acceptance even where the environment would not otherwise allow it.
This is based on a legacy commit which installs a local grammar. A
followup commit will change to the grammar in SPIRV-Headers.

* Initial support for SPV_KHR_integer_dot_product
- Adds new operand types for packed-vector-format
- Moves ray tracing enums to the end
- PackedVectorFormat is a new optional operand type, so it requires
special handling in grammar table generation.
- Add SPV_KHR_integer_dot_product to optimizer whitelists.
- Pass-through validation: valid cases pass validation
Validation errors are not checked.
- Update SPIRV-Headers

This pass converts an internal form of GLSLstd450 Interpolate ops
to the externally valid form. The external form takes the lvalue
of the interpolant. The internal form can do a load of the interpolant.
The pass replaces the load with its pointer. The internal form is
generated by glslang and possibly other frontends for HLSL shaders.
The new pass is called as part of HLSL legalization after all
propagation is complete.
Also adds internal interpolate form to pre-legalization validation
* 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
This CL adds some extra new lines and context comments into the
spirv-dis output format. This CL adds:
- Blank line and '; Annotations' before decorations
- Blank line and '; Debug Information' before debug instructions
- Blank line and '; Types, variables and constants' before type section
- Blank line and '; Function <name>' before each function.
Issue #788
This change introduces various strategies for controlling the manner
in which fuzzer passes are applied repeatedly, including infrastructure
to allow fuzzer passes to be recommended based on which passes ran
previously.
Motivated by integrating spirv-reduce into spirv-fuzz, so that an
added function can be made smaller during shrinking, this adds support
in spirv-reduce for asking reduction to be restricted to the
instructions of a single specified function.
* Generate ext inst table for reflection
* Change build to use grammar files from SPIRV-Headers instead of
SPIRV-Tools
* Add enum for clspv reflection extended instruction set
* count it as non-semantic
* validate clspv reflection extended instruction set
* Remove local extended inst sets
* update headers deps
* Update nbuilds to use grammars from SPIRV-Headers instead of
local duplicates
* Avoid operand type range checks
Deprecates the SPV_OPERAND_TYPE_FIRST_* and SPV_OPERAND_TYPE_LAST_*
macros.
The "variable" and "optional" operand types are only for internal use.
Export spvOperandIsConcrete instead, as that should cover intended
external uses.
Test that each operand type is classified either as one of:
- a sentinel value
- a concrete operand type
- an optional operand type (which includes variable-expansion types)
Test that each concrete and optional non-variable operand type
has a name for use internally when generating messages.

This new API lets clients request a minimal spv_target_env value
that supports a given Vulkan and SPIR-V version, by a generic
numbering scheme (as already defined by Vulkan and SPIR-V specs).
This breaks a formal source dependency from Glslang to SPIRV-Tools.
When a new API is rolled out, such as Vulkan 1.2, Glslang currently
needs to reference a specific SPIRV-Tools enum by name.
* Clone opencl.debuginfo.100 grammar from debuginfo grammar
Update version number to 200 revision 2
* Apply content from OpenCL.DebugInfo.100 extension text
* Rename grammar file
* Support OpenCL.DebugInfo.100 extended instructions
Add support for prefixing operand type names, to disambiguate
them between different instruction sets.
* Add tests for OpenCL.DebugInfo.100
* Support lookup of OpenCL.DebugInfo.100 extinst
* Add tests for enum values
* Recognize 2017-2019 as copyright date range
* Android.mk: support OpenCL.DebugInfo.100 extended instruction set
Also, stop generating core instruction tables for non-unified1 versions
of the grammar.
* Imported entity operand type is concrete
* Bazel: Suppoort OpenCL.DebugInfo.100
* BUILD.gn: Support OpenCL.DebugInfo.100
Add support for SPV_KHR_non_semantic_info
This entails a couple of changes:
- Allowing unknown OpExtInstImport that begin with the prefix `NonSemantic.`
- Allowing OpExtInst that reference any of those sets to contain unknown
ext inst instruction numbers, and assume the format is always a series of IDs
as guaranteed by the extension.
- Allowing those OpExtInst to appear in the types/variables/constants section.
- Not stripping OpString in the --strip-debug pass, since it may be referenced
by these non-semantic OpExtInsts.
- Stripping them instead in the --strip-reflect pass.
* Add adjacency validation of non-semantic OpExtInst
- We validate and test that OpExtInst cannot appear before or between
OpPhi instructions, or before/between OpFunctionParameter
instructions.
* Change non-semantic extinst type to single value
* Add helper function spvExtInstIsNonSemantic() which will check if the extinst
set is non-semantic or not, either the unknown generic value or any future
recognised non-semantic set.
* Add test of a complex non-semantic extinst
* Use DefUseManager in StripDebugInfoPass to strip some OpStrings
* Any OpString used by a non-semantic instruction cannot be stripped, all others
can so we search for uses to see if each string can be removed.
* We only do this if the non-semantic debug info extension is enabled, otherwise
all strings can be trivially removed.
* Silence -Winconsistent-missing-override in protobufs
Adds an option to run the validator on the SPIR-V binary after each
fuzzer pass has been applied, to help identify when the fuzzer has
made the module invalid. Also adds a helper method to allow dumping
of the sequence of transformations that have been applied to a JSON
file.
To aid in debugging issues in spirv-fuzz, this change adds an option whereby the SPIR-V module is validated after each transformation is applied during replay. This can assist in finding a transformation that erroneously makes the module invalid, so that said transformation can be debugged.
* Ensure same enum values have consistent extension lists
* val: fix checking of capabilities
The operand for an OpCapability should only be
checked for the extension or core version.
The InstructionPass registers a capability, and all its implied
sub-capabilities before actually checking the operand to an
OpCapability.
* Add basic support for SPIR-V 1.5
- Adds SPV_ENV_UNIVERSAL_1_5
- Command line tools default to spv1.5 environment
- SPIR-V 1.5 incorporates several extensions. Now the disassembler
prefers outputing the non-EXT or non-KHR names. This requires
updates to many tests, to make strings match again.
- Command line tests: Expect SPIR-V 1.5 by default
* Test validation of SPIR-V 1.5 incorporated extensions
Starting with 1.5, incorporated features no longer require
the associated OpExtension instruction.
Adds to spirv-fuzz the option to shrink a sequence of transformations
that lead to an interesting binary to be generated, to find a smaller
sub-sequence of transformations that still lead to an interesting (but
hopefully simpler) binary being generated. The notion of what counts
as "interesting" comes from a user-provided script, the
"interestingness function", similar to the way the spirv-reduce tool
works. The shrinking process will give up after a maximum number of
steps, which can be configured on the command line.
Tests for the combination of fuzzing and shrinking are included, using
a variety of interestingness functions.
Adds a library for spirv-fuzz, consisting of a Fuzzer class that will
transform a module with respect to (a) facts about the module provided
via a FactManager class, and (b) a source of random numbers and
parameters to control the transformation process provided via a
FuzzerContext class. Transformations will be applied via classes that
implement a FuzzerPass interface, and both facts and transformations
will be represented via protobuf messages. Currently there are no
concrete facts, transformations nor fuzzer passes; these will follow.
* Make pointers to logically matching types interchangeable with option.
DXC will be generating code where the function parameters will be a more
generic type that the actual parameter. They should be logically
matching and the decorations of the actual parameter must be a superset
of the decorations of the formal parameter.
We want to accept this code with an options so that spirv-opt can then
inline and fix the type mismatch. We will accept this under a new
options `--before-hlsl-legalization`.
The new option will also imply `relax-logical-pointer` so that HLSL
frontends will need to use just the one more generic option.
Moved the |LogicallyMatches| to the validation state to make it
available in more places. Also added a parameter to have it check the
decorations. I did not do a separate function for the decorations
because checking the decorations involves making sure the types
logically match anyway.
