- Rejects bad modules by running the SPIR-V validator first
- Skips exception-heavy SPIRV-Cross SPIR-V parser
- Support NV extensions for shader stages
- Require SPIRV-Tools and SPIRV-Headers with SPIR-V 1.4 support

prior to running the legalization recipe.
v2018.0 2018-10-01

- Add a shared library version of libshaderc
- Support GLSL 4.6 and ESSL 3.2
- Fail compilation if a resource does not have a binding.
- Add options for automatically setting bindings for (uniform) resources that
don't have bindings set in shader source.
- Add options for automatically setting locations for pipline inputs and outputs.
- Add option for using HLSL IO mappings as expressed in source.
- Add options for setting resource binding base numbers.
- Add option to use HLSL resource register numbers for bindings.
- HLSL compilation now defaults to HLSL packing rules.
(This change is inherited from Glslang commit 7cca140.)
- HLSL compilation runs SPIR-V "legalization" transforms to reduce
manipulation of opaque handles (e.g. images), to satisfy Vulkan rules.
- Adapt to Glslang generator version numbers:
- To 2: a fix for code generation for atomicCounterDecrement.
- To 3: change memory barrier semantics masks
- To 4: generate more access chains for swizzles
- CMake install rules uses GNUInstallDirs. For example, install to lib64
when that is the norm for the target system.

that don't have an explicit 'binding' layout in the shader source.

glslc
- glslc adds -flimit=<setting>

limit syntax.

configuration files, i.e. the output of "glslangValidator -c".
- Enable AMD extensions by default in GLSL compilation
- Fixes issues:
#281: Work around Android build issue with abspath on Windows
#283: Increase default maxDrawBuffers to 4, to match Vulkan/GLES3.0
v2016.1 2016-10-12

## 11.1.0 2020-12-07
### Other changes
* Added ray-tracing extension support
## 11.0.0 2020-07-20
### Breaking changes
#### Visual Studio 2013 is no longer supported
[As scheduled](https://github.com/KhronosGroup/glslang/blob/9eef54b2513ca6b40b47b07d24f453848b65c0df/README.md#planned-deprecationsremovals),
Microsoft Visual Studio 2013 is no longer officially supported. Please upgrade
to at least Visual Studio 2015.
## 10.15.3847 2020-07-20
### Breaking changes
* The following files have been removed:
* `glslang/include/revision.h`
* `glslang/include/revision.template`
The `GLSLANG_MINOR_VERSION` and `GLSLANG_PATCH_LEVEL` defines have been removed
from the public headers. \
Instead each build script now uses the new `build_info.py`
script along with the `build_info.h.tmpl` and this `CHANGES.md` file to generate
the glslang build-time generated header `glslang/build_info.h`.
The new public API to obtain the `glslang` version is `glslang::GetVersion()`.
### Other changes
* `glslang` shared objects produced by CMake are now `SONAME` versioned using
[Semantic Versioning 2.0.0](https://semver.org/).

// The SPIR-V spec requires code blocks to appear in an order satisfying the
// dominator-tree direction (ie, dominator before the dominated). This is,
// actually, easy to achieve: any pre-order CFG traversal algorithm will do it.
// Because such algorithms visit a block only after traversing some path to it
// from the root, they necessarily visit the block's idom first.
//
// But not every graph-traversal algorithm outputs blocks in an order that
// appears logical to human readers. The problem is that unrelated branches may
// be interspersed with each other, and merge blocks may come before some of the
// branches being merged.
//
// A good, human-readable order of blocks may be achieved by performing
// depth-first search but delaying merge nodes until after all their branches
// have been visited. This is implemented below by the inReadableOrder()
// function.

// Access chain design for an R-Value vs. L-Value:
//
// There is a single access chain the builder is building at
// any particular time. Such a chain can be used to either to a load or
// a store, when desired.
//
// Expressions can be r-values, l-values, or both, or only r-values:
// a[b.c].d = .... // l-value
// ... = a[b.c].d; // r-value, that also looks like an l-value
// ++a[b.c].d; // r-value and l-value
// (x + y)[2]; // r-value only, can't possibly be l-value
//
// Computing an r-value means generating code. Hence,
// r-values should only be computed when they are needed, not speculatively.
//
// Computing an l-value means saving away information for later use in the compiler,
// no code is generated until the l-value is later dereferenced. It is okay
// to speculatively generate an l-value, just not okay to speculatively dereference it.
//
// The base of the access chain (the left-most variable or expression
// from which everything is based) can be set either as an l-value
// or as an r-value. Most efficient would be to set an l-value if one
// is available. If an expression was evaluated, the resulting r-value
// can be set as the chain base.
//
// The users of this single access chain can save and restore if they
// want to nest or manage multiple chains.

// This simultaneously
//
// * Makes each individual allocation much more efficient; the
// typical allocation is trivial.
// * Completely avoids the cost of doing individual deallocation.
// * Saves the trouble of tracking down and plugging a large class of leaks.
//
// Individual classes can use this allocator by supplying their own
// new and delete methods.

// STL containers can use this allocator by using the pool_allocator
// class as the allocator (second) template argument.
