494a02a2b0 Semantics: Geometry stage can support max_vertices = 0.
To do this, more generally use a named -1 as a not set value.

989df85dcd Array-sizing bug fix: multiple array initializers of different size in the same declaration.
Handles the case of
    float[] x = float[] (1.0, 2.0, 3.0),
            y = float[] (1.0, 2.0, 3.0, 4.0);
where a shallow copy of the type arrayness from the left-most float[]
was getting used twice.

876a0e392e Add an osinclude.h below each OS directory, redirects by platform macro
* Linux folder has been renamed to Unix, to match defines and so that it
  compiles on OS X.
* This removes the need for a per-platform include search path for the
  right OS folder

ef676b0a59 Front-end "pure" built-in TOperator: Finish adding full support, but still turned off.
This is to avoid all need to do text comparison of built-in function names
when consuming the AST.  All built-in functions get enumerants.

Will want to turn on soon.  See PureOperatorBuiltins.  See issue #8.

65c78a0b62 Array of array: Implement the core functionality: types, constructors, operations.
There will be subsequent commits to refine semantics, esp. version-specific semantics,
as well as I/O functionality and restrictions.

Note: I'm getting white-space differences in the preprocessor test results,
which I'm not checking in.  I think they need to be tagged as binary or something.

b35483587f Array of Array prep: Turn a batch of 0's into nullptr or UnsizedArraySize.
Added some const as well. This will remove camouflage of the next commit,
which will add the bulk of Array of Array semantics and functionality.
(Note the basic grammar and data structure is already in place.)

5011fbebc3 Extend the syntax of #line and __FILE__ to support filename strings.
According to the GLSL spec, the second parameter to #line should be
an integer source string number and __FILE__ will be substituted
with the integer source string number currently processed. This
patch extends the syntax of #line and __FILE__. Now #line accepts
as the second parameter a filename string quoted by double quotation
marks. And if such a #line is set, __FILE__ will be substituted with
the currently set filename string. The implementation is done via
introducing a new extension GL_GOOGLE_cpp_style_line_directive using
the extension framework.

The purpose is to support cpp-style #line directives, which is
required by #include.

c777fc2c4c Scanning: 1) rationalize end-of-input everywhere, 2) prevent infinite loop at end-of-input, 3) use positive chars.
Fixes issue #25. (char 255 aliased to -1 and missing tests for end of input).

1) All layers of input scanning now share a single EndOfInput value.
This avoids translation of it across layers of encapsulation.

2) Some places looking for end of line were not stopping on EndOfInput.

3) Use of "char" for the input made char values > 127 be negative numbers.
This allowed for aliasing of 255 to -1, etc.  This is fixed by using
unsigned char.

46ea5396ef Fix empty line handling in line directive callback.
The current line number for the #line directive should be passed
in as parameter to the line directive callback. Without it, we
don't know how many empty lines we should output.

5cbc990a0a Fix line number handling in line directive callback.
The line argument passed into the lineCallback function is the
literal value of the first argument of the #line directive.
lastLine in DoPreprocessing() should be updated taking into
consideration the different definitions for #line between specs.

Add a test to reveal the bug.

68d78fd31e Updated command-line options, adding -o for saving binaries, -G for OpenGL SPIR-V validation, -v etc.
Old uses should still work as they did before.
Also encapsulated use of these flags during parsing, for the parse context.
Added SPIR-V version to -v.

93deac5295 Fix incompatibility with <GL/glext.h>
New extensions in glext.h follow the pattern:

    #ifndef GL_ARB_texture_rectangle
    #define GL_ARB_texture_rectangle 1
    #define GL_TEXTURE_RECTANGLE_ARB          0x84F5
    #define GL_TEXTURE_BINDING_RECTANGLE_ARB  0x84F6
    #define GL_PROXY_TEXTURE_RECTANGLE_ARB    0x84F7
    #define GL_MAX_RECTANGLE_TEXTURE_SIZE_ARB 0x84F8
    #endif /* GL_ARB_texture_rectangle */

Versions.h tries to declare:

    const char* const GL_ARB_texture_rectangle = "GL_ARB_texture_rectangle";

Which means, if you've included glext.h before Versions.h, that the
compiler will see "const char* const 1 = ...", and rightly refuse to
continue.

The ham-fisted approach taken here is to rename the variables in
Versions.h with a leading underscore.  This does sort of undermine the
comment about "better to have the compiler do spelling checks", but.

1189a7bc4a Make double underscore "__" an error for ES 300, but a warning for 310.
The 310 spec (and desktop specs) have clarified this is a waring, not an
error, but 300 tests still expect an error.
