Remove WebGPU support (#4108)
Leaves SPV_ENV_WEBGPU_0 enum in place, but marked deprecated, so users
of the library are not broken by an API enum being removed.

Fixes #4101

Add spvParseVulkanEnv (#3142)
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.

5a48c0da15 SPIRV-Tools support for SPIR-V 1.5 (#2865)
* 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.

df86bb44fe Replace global static map with an array of pairs (#2691)
* Replace global static map with an array of pairs

\#2687 introduced a global static map, which isn't allowed by
the style guide and caused an issue in DXC.

This change replaces it with an array of pairs.

bec7e0393f Add all accepted target environments to the tools' help texts (#2687)
Several tools take a --target-env option to specify the SPIR-V
environment to use. They all use spvParseTargetEnv to parse
the user-specified string and select the appropriate spv_target_env
but all tools list only _some_ of the valid values in their help
text.

This change makes the help text construction automatic from the
full list of valid values, establishing a single source of truth
for the values printed in the help text. The new utility function
added allows its user to specify padding and wrapping constraints
so the produced strings fits well in the various help texts.

Support SPIR-V 1.4 (#2550)
* SPIR-V 1.4 headers, add SPV_ENV_UNIVERSAL_1_4

* Support --target-env spv1.4 in help for command line tools

* Support asm/dis of UniformId decoration

* Validate UniformId decoration

* Fix version check on instructions and operands

Also register decorations used with OpDecorateId

* Extension lists can differ between enums that match

Example: SubgroupMaskEq vs SubgroupMaskEqKHR

* Validate scope value for Uniform decoration, for SPIR-V 1.4

* More unioning of exts

* Preserve grammar order within an enum value

* 1.4: Validate OpSelect over composites

* Tools default to 1.4

* Add asm/dis test for OpCopyLogical

* 1.4: asm/dis tests for PtrEqual, PtrNotEqual, PtrDiff

* Basic asm/Dis test for OpCopyMemory

* Test asm/dis OpCopyMemory with 2-memory access

Add asm/dis tests for OpCopyMemorySized

Requires grammar update to add second optional memory access operand
to OpCopyMemory and OpCopyMemorySized

* Validate one or two memory accesses on OpCopyMemory*

* Check av/vis on CopyMemory source and target memory access

This is a proposed rule. See
https://gitlab.khronos.org/spirv/SPIR-V/issues/413

* Validate operation for OpSpecConstantOp

* Validate NonWritable decoration

Also permit NonWritable on members of UBO and SSBO.

* SPIR-V 1.4: NonWrtiable can decorate Function and Private vars

* Update optimizer CLI tests for SPIR-V 1.4

* Testing tools: Give expected SPIR-V version in message

* SPIR-V 1.4 validation for entry point interfaces

* Allow only unique interfaces
* Allow all global variables
* Check that all statically used global variables are listed
* new tests

* Add validation fixture CompileFailure

* Add 1.4 validation for pointer comparisons

* New tests

* Validate with image operands SignExtend, ZeroExtend

Since we don't actually know the image texel format, we can't fully
validate.  We need more context.

But we can make sure we allow the new image operands in known-good
cases.

* Validate OpCopyLogical

* Recursively checks subtypes
* new tests

* Add SPIR-V 1.4 tests for NoSignedWrap, NoUnsignedWrap

* Allow scalar conditions in 1.4 with OpSelect

* Allows scalar conditions with vector operands
* new tests

* Validate uniform id scope as an execution scope

* Validate the values of memory and execution scopes are valid scope
values
* new test

* Remove SPIR-V 1.4 Vulkan 1.0 environment

* SPIR-V 1.4 requires Vulkan 1.1

* FIX: include string for spvLog

* FIX: validate nonwritable

* FIX: test case suite for member decorate string

* FIX: test case for hlsl functionality1

* Validation test fixture: ease debugging

* Use binary version for SPIR-V 1.4 specific features

* Switch checks based on the SPIR-V version from the target environment
to instead use the version from the binary
* Moved header parsing into the ValidationState_t constructor (where
version based features are set)
* Added new versions of tests that assemble a 1.3 binary and validate a
1.4 environment

* Fix test for update to SPIR-V 1.4 headers

* Fix formatting

* Ext inst lookup: Add Vulkan 1.1 env with SPIR-V 1.4

* Update spirv-val help

* Operand version checks should use module version

Use the module version instead of the target environment version.

* Fix comment about two-access form of OpCopyMemory

Remove asserts around environment determination. (#2040)
This CL removes several asserts around determining the SPIR-V
environment. In each case we already return a default value if
assertions are compiled out, so just return the default value.

ba602c9059 Add a WIP WebGPU environment. It disallows OpUndef
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.

95843d7bd0 New spirv-1.3 rules for control barrier
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/1427

Adjusting validation to the new rule:
"Before version 1.3, it is only valid to use this instruction with
TessellationControl, GLCompute, or Kernel execution models.
There is no such restriction starting with version 1.3."

Also fixed wrong version numbers in source/spirv_target_env.cpp.

00fa39318f Support SPIR-V 1.3 and Vulkan 1.1
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

bdc78377bc Added Vulkan-specifc checks to image validation
Implemented Vulkan-specific rules:
- OpTypeImage must declare a scalar 32-bit float or 32-bit integer type
for the “Sampled Type”.
- OpSampledImage must only consume an “Image” operand whose type has its
“Sampled” operand set to 1.

6fa3f8aad9 Remove dependency on SPIR-V headers in libspirv.h.
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.
