spirv-val: Consistently quote ids in messages (#4950)
Half the messages used to output 'id[%name]' and half id[%name].  With
this change, all messages consistently output 'id[%name]'.  Some typos
are also fixed in the process.

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

Make pointers to isomorphic type interchangeable with option. (#2570)
* 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.

Fixes #2535

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

Validate all type ids. (#1868)
* Validate all type ids.

The validator does not check if the type of an instruction is actually
a type unless the OpCode has a specific requirement.  For example,
OpFAdd is checked, but OpUndef is not.

The commit add a generic check that if there is a type id then the id
defines a type.

http://crbug.com/876694

* Merge other checks for type into new one.

There are a couple check that the type id is a type for specific
opcodes.  Those have been mereged into 1.

Small changes to other test cases to make them valid enough for the
purpose of the test.

instruction directly.

Change ValidationState::diag to accept an Instruction. (#1749)
This CL changes the signature of diag() to accept an Instruction instead
of the instructions position.

A deprecated variant that accepts the position is available but will be
removed in the near future.

Update error messages in validate_composites. (#1743)

validate_composites. The operator will be printed on the next line with
the disassembly.

Move validation files to val/ directory (#1692)
This CL moves the various validate files into the val/ directory with
the rest of the validation infrastructure. This matches how opt/ is
setup with the passes with the infrastructure.
