against a null string.

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.

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.)

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.

6ab3d582d6 Preprocessor: 1) Rationalize the "fixed atom" scheme, 2) remove redundant lookups when the text is already available.
This simplification is a prelude to eliminating what I appear unnecessary
symbol inserts into tables when tokenizing in the preprecessor, which
show up as taking notable time. (Performance issue.)  It also simply makes
the preprocessor easier to understand, which it is badly in need of.

c4d20e0041 Simplify function calls for extensionsTurnedOn().
Lots of places in the code use extensionsTurnedOn(1, ...). This
patch introduces a new method, extensionTurnedOn(), for testing
if a single extension is turned on.

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.

a5ade51363 Fix most clang warnings
- member initializing order in some constructors
- missing default branches in switch-case
- uninitialized variable if switch-case default (uncritical because
  program would exit)
- && and || brace warnings in if()

9b0d9c8aa4 Use E_ prefix instead of _ for distinguishing extension strings from glext.h 2015-07-03 09:24:46 -06:00

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.

edadf45605 glslang: Add API override of version and profile for testing purposes. From Lei Zhang <antiagainst@google.com>.
Add defaultProfile and forceDefaultVersionAndProfile into shader
compilation interface.

forceDefaultVersionAndProfile allows us to force parsing the input
shaders using defaultVersion and defaultProfile, regardless of
the #version directive in input shaders.

These two parameters enables us to programmatically invoke glslang
but specify version and profile from somewhere else like command
line.
