275d7ae882 only declare compatibility gl_ variables in compatibility mode 
avoid declaring them in GLSL 1.50+ if core profile is chosen by the
version statement

4bfbf62794 Add support for GL_EXT_shared_memory_block 
Uses SPV_KHR_workgroup_memory_explicit_layout.  Note that if
GL_EXT_scalar_block_layout is enabled, Workgroup blocks can also use
scalar layout.

1c3ab274b1 Test Results Only: Include size in implicitly sized arrays (change to unsized). 
This effects 60 tests, in a trivial way, but is critical to factor out this
noise from future planned changes.

ba5cc2fafa GLSL: Fix #822: Improve information given for syntax errors. 
Also, fixed one test file that didn't have its syntax error as the last line.

71c100d7c0 GLSL output: Removed fixed-size buffer; fixes #769. 
Makes some white-space differences in most output, plus a few cases
where more could have been put out but was cut short by the previous
fix-sized buffer.

906cc21816 Linker: Eliminate uncalled functions, because they can be ill-defined. 
Fixes issue #610. Also provides a testing option to keep uncalled functions.

d3f1122a44 Whole stack: Fix stale types in the AST linker object nodes, fixing #557. 
Rationalizes the entire tracking of the linker object nodes, effecting
GLSL, HLSL, and SPIR-V, to allow tracked objects to be fully edited before
their type snapshot for linker objects.

Should only effect things when the rest of the AST contained no reference to
the symbol, because normal AST nodes were not stale. Also will only effect such
objects when their types were edited.

eb505e4262 Allow future keywords to be accessed as members in a struct. 
This fixes a bug where a token that could be a keyword in one version
is not a keyword in another version, but treated like a non-member after
a "." dereference.

fc51d284aa Backward incompatible: Turn on PureOperatorBuiltins: use only enum-based built-in functions in the AST. 
If this breaks your AST consumer, best is to modify it to test
against the enum values instead of doing string comparisons on
built-in function names.  This is the reason the change was made.

If you need the old behavior, you should be able to get it back by changing
PureOperatorBuiltins to be false instead of true.  This path will work for
a while, but is marked deprecated.

Also, the old behavior is tagged as release 2.4.

e88217b7d8 Add more TOperator: fma/frexp/ldexp, AddCarry/SubBorrow/MulExtended/Bit*/Find*, (un)pack4x8/2x32, ftransform. 
Also corrects some existing ones missing the "Op" part of their name.

cf0206c341 Restore r26245 and all tests and test results since 4/1: 
r26245: Remove "not yet complete" warning for versions 130 and 140, after tidying up a bit and adding tests.  Token pasting is the only known missing feature, and gives its own message now on use.

f2d042a1fe Non-functional, infrastructure: Be more explicit about "implicit array sizes", improving the infrastructure for handling them. Also fix some output that was too big for its buffer. 
There is more upcoming functionality for link-time sizing of implicitly-sized arrays that will use this.

623833fabc Tessellation partial implementation (not ready for use yet), including: 
- the built-in constants
 - built-in variable declarations, some dependent on gl_MaxPatchVertices
 - layout qualifier for vertices (shared with geometry shader max_vertices)
 - layout qualifiers for vertex spacing, vertex order, point mode, and primitive type
 - link semantics for layout qualifiers

Still TBD:
 - patch qualifier and arrayed input handling
 - sizing of gl_out[]
 - additional semantic checking
 - supporting the extension on version 150

d6bef9186b Correct textureGather*() extension support:

5134b9cf57 Track what ins/outs/uniforms are used, so that errors like "declare after use" or "can't use both XXX and YYY" can be issued. So far, used this for invariant, gl_FragColor et. al., and gl_FragCoord use before redeclaration. 
Also made all tests in testlist include linker tests.
