* Code refine and adding missing features
1. Add new level for built in symbols.
2. Fix issues for structure members' qualifiers.
3. Global qualifier fix.
4. IO Mapper refine. Add support for checking with mangle names.
* Additional missing features
* Invariant member. (Only check non-interface).
* Split block nesting level and struct nesting level. To fix issues of checking 'invariant' qualifier.
Current grammar would check block/struct member without its parent class's information.
So we split nesting level, and 'invariant' would only be checked within a struct.
* Format anonymous block names. Refine codes for symbols from all kinds of resouces.
* Fix writeonly check.
* Use LValueBase to find operator.
* Fix random null ptr issue.
* invariant check, stage in io mapping, reference parameter should be used and remove wrong codes introduced with ordering vector.
* Remained: to be fixed with double check link.vk.multiblocksValid
* Fix version error.
invariant
* Revert loc modification.
Translate printf() to what GL_EXT_debug_printf has done. HLSL could
define non-constant string variable and we don't have such features
in SPIR-V, so just support constant string variable.
TIntermediate was constructed without initializing any of the `resources` fields,
and `TProgram::linkStage()` was not calling `TIntermediate::setLimits()`
after constructing new `TIntermediate`s for non-first stages.
Fields of `resources` were then read in `TIntermediate::finalCheck()`
triggering undefined behavior.
This CL makes three changes:
(1) `TIntermediate::setLimits()` is now called for non-first stages by
copying the `firstIntermediate`'s limits. This ensures that the
`resources` fields is initialized, fixing the bug.
(2) `TIntermediate::resources` is now wrapped in a `MustBeAssigned<>`
helper struct, asserting in non-release builds that this field is
always initialized before reading.
(3) `TIntermediate::resources` is now zero-initialized, so that if
the `TIntermediate::resources` field is not set in a release build
(and so the `assert()` will be disabled) behavior is still
deterministic.
Fixes#2423
* Preprocessor related fix
1). Accoding to ESSL spec : All macro names containing two consecutive underscores ( __ ) are reserved for future use as predefined macro names, so just report a warning instead of error when the shader defines the macro names begining with '__';
2. According to spec: If an implementation does not recognize the tokens following #pragma, then it will ignore that pragma, so report a compile-time warning intead of error for the following statement:
#pragma debug(1.23)
3. The 'defined' macro should be allowed to expand and '__LINE__' should be allowed to be replaced with its original line number (otherwise, other expanding macros may change this value).
4. Add a flag 'indentifierSeen' in PPContext to indicate whether the any non-preprocessor tokens is existed before the extension directives, because the built-in symbols and functions are parsed before paring the user shader, so add a 'shaderSource' flag to check this error only for the user shader source;
5. Add missing type int16 and uint16.
* Add test results, remove restriction of #extension.
1. Remove extension restriction in first line , as this is contraversy now.
2. The following shader is compiled failed as glslang consider the keyword 'defined' can not be undefined(in the 9th line: "#define defined BBB")
The shader is as following:
According to ES3.0 spec: It is an error to undefine or to redefine a built-in (pre-defined) macro name.
This rule is aimed to the __LINE__, __FILE__, __VERSION__ and GL_ES,
the keyword "defined" should not be restricted by this rule,
so change the compile error to warning and make the following shader compile successfully.
* 1. Using relaxedError to control error/warning report level. 2. remove #extension restriction. 3. Fix version related issue.
1. Using relaxedError to control error/warning report level. 2. remove #extension restriction. 3. Fix version related issue.
* Add test results
* Turn conditional warnings about pragma to unconditional ones.
* Remove image2DShadow and other 3 tokens. Refine codes.
Remove image2DShadow and other 3 tokens. Refine codes.
* 110scope.vert has redefinition part of what's removed from 100scope.vert
We need separate concepts for
- total set of extensions ever enabled, for the back end
- current state of extensions, for parsing
- the set of features currently enabled for building the AST
This detangles incorrect conflation of HLSL with GLSL extensions,
defers asking expensive questions until it's time to ask, and removes
some dead code.
The scalar type was already the basic type passed in.
Also factored out of this the checking of extensions for 8/16-bit stuff.
This code seems wrong in several ways, but for now just documenting it.
This change strips a few features similar to GLSLANG_WEB but doesn't
remove every detail like the latter. It also hardcodes profile/version
to core/450.
In particular, TBuiltIns::initialize is specialized to remove most of
what is not supported or won't be supported by ANGLE. The result of
this function is parsed with TParseContext::parseShaderStrings which is
a performance bottleneck.
This change shaves about 300KB off of ANGLE's binary size and reduces
the cost of SetupBuiltinSymbolTable to nearly a sixth.

iOS 8 does not support `thread_local`, which is still in use.
Another approach will have to be found.
This change is a revert of the following changes:
a3845240 - "Simplify PoolAlloc with use of thread_local."
abf92c80 - "Deprecate InitializeDll functions"
33585c87 - "Limit visibility of symbols for internal libraries"
Issue: #2346
glslang is using C++ 11, which has first class support for variables of the `thread_local` storage class.
By dropping the use of the `OS_[GS]etTLSValue`, we can simplify the logic, and have it support a thread-local default allocator if none is provided.
Issue: #2346
when traversing the AST to find live UBOs etc, also traverse
references to global module-level variables, incase they are
being filled in from UBOs etc.
When a return value's type has no precision qualification (e.g., the return
expression is formed from a constructor), and the formal function return type
has a precision qualification, back propagate that from the return type to the
type of the return value's expression.
This PR significantly reworks the way glslang is versioned.
Instead of committing changes to the `GLSLANG_MINOR_VERSION` define in
`glslang/Public/ShaderLang.h`, and using `make-revision` to generate
`GLSLANG_PATCH_LEVEL` in `glslang/Include/revision.h`, all version
information is now derived from the new `CHANGES.md` file.
`CHANGES.md` acts as the single source of truth for glslang version
information, along with a convenient place to put all release notes for
each notable change made.
`CHANGES.md` is parsed using the new `build_info.py` python script.
This script can read basic template files to produce new source files,
which it does to read the new `build_info.h.tmpl` to generate (at build
time) a glslang private header at
`<build-dir>/include/glslang/build_info.h`.
I've written generators for each of the CMake, Bazel, gn, and
`Android.mk` build scripts.
The new version code conforms to the Semantic Versioning 2.0 spec.
This new version is also used by the CMake rules to produce versioned
shared objects, including a major-versioned SONAME.
New APIs:
---------
* `glslang::GetVersion()` returns a `Version` struct with the version
major, minor, patch and flavor.
Breaking API changes:
---------------------
* The public defines `GLSLANG_MINOR_VERSION` and `GLSLANG_PATCH_LEVEL`
have been entirely removed.
* `glslang/Public/ShaderLang.h` and `glslang/Include/revision.h` have
been deleted.
* Instead, `<build-dir>/include/glslang/build_info.h` is created in
the build directory, and `<build-dir>/include` is a CMake `PUBLIC`
(dependee-inherited) include directory for the glslang targets.
* `<build-dir>/include/glslang/build_info.h` contains the following
new #defines:
`GLSLANG_VERSION_MAJOR`, `GLSLANG_VERSION_MINOR`,
`GLSLANG_VERSION_PATCH`, `GLSLANG_VERSION_FLAVOR`,
`GLSLANG_VERSION_GREATER_THAN(major, minor, patch)`,
`GLSLANG_VERSION_GREATER_OR_EQUAL_TO(major, minor, patch)`,
`GLSLANG_VERSION_LESS_THAN(major, minor, patch)`,
`GLSLANG_VERSION_LESS_OR_EQUAL_TO(major, minor, patch)`
* The CMake install output directory contains a copy of
`build_info.h` at: `include/glslang/build_info.h`
* Python3 is now always required to build glslang (likely always
required for transitive dependency builds).
glslang.y is specialized to remove what is not supported or won't be
supported by ANGLE.
This change shaves about 125KB off of ANGLE's binary size with minor
improvement to the cost of SetupBuiltinSymbolTable.

`glslang_pch()` did manual mangling of the compiler flags to enable pre-compiled headers.
I couldn't get this approach to work with the `MachineIndependent` subdirectory, but fortunately CMake has added first-class support for precompiled headers in 3.16, which does work with subdirectories.
Moved `glslang_pch()` to the other global function declarations.
`glslang_pch()` is a no-op when using CMake earlier than `3.16`.
CMake's PCH implementation does not need the `pch.cpp` files, so just remove them.
Fix#2298.
The AST has two precisions, an operation precision and a result precision.
Actual use of GLSL with mediump samplers wants the result precision, so
pick that up instead of the operation precision.
Now that the HLSL source files are part of the `glslang` target (#2271), it makes sense for these to sit in the `glslang` directory.
Changed the case of the directory from `hlsl` to `HLSL` to better match the sibling directories.
* Fix xfb_stride limit issue
Unsized array can't apply to transform trace. layout qualifier "offset" require GL_ARB_enhanced_layouts enable or glsl core version > 440.
* Add negative test for xfb limit
* update case result
* Fix compile information issue
Fix compile information issue and test comment issue.
* remove es profile condition, use profileRequires to limit.
* Fix xfb_stride limit issue
Unsized array can't apply to transform trace. layout qualifier "offset" require GL_ARB_enhanced_layouts enable or glsl core version > 440.
Add negative test for xfb limit
* Move es profile check out of version number check
* Adjust error information and related cases
remove the new version check, refine original version check.
* Revert condition for vulkan, and remove redundant test code.
* Add Shared/Std140 SSBO process & top-level array elements related
process
1.Add process options for shared/std140 ssbo, following ubo process
2.Add IO Variables reflection option, would keep all input/output
variables in reflection
3.Add Top-level related process, fix top-level array size issues,
following spec
4.Split ssbo/ubo reflection options, merge blowup expanding all into
function blowupActiveAggregate to allow other functions keep same entry
format.
Add options in StandAlone and test symbols.
1. Add options in StandAlone for std140/shared ubo/ssbo and all io variables reflection.
2. Add test for ssbo. When EShReflectionSharedStd140SSBO turns on, generated symbol and output would be different, to remind the difference. Defaultly disabled and nothing would change, nor blocking normal test.
* Add options in runtest script, refresh test results.
Add options in StandAlone:
--reflect-all-io-variables --reflect-shared-std140-ubo --reflect-shared-std140-ssbo
refresh test results.
Now the index, size of unsized array are expected.
