- Support GL_AMD_shader_ballot (SPV_AMD_shader_ballot).
- Support GL_AMD_shader_trinary_minmax (SPV_AMD_shader_trinary_minmax).
- Support GL_AMD_shader_explicit_vertex_parameter
(SPV_AMD_shader_explicit_vertex_parameter).
- Support GL_AMD_gcn_shader (SPV_AMD_gcn_shader).
Note this requires test-based piecing together of the preamble string,
so it changed to being a std::string to make it easier to do.
This closes issue #254.
- Add new keyword int64_t/uint64_t/i64vec/u64vec.
- Support 64-bit integer literals (dec/hex/oct).
- Support built-in operators for 64-bit integer type.
- Add implicit and explicit type conversion for 64-bit integer type.
- Add new built-in functions defined in this extension.
Adds parseVersions.h as the base TParseVersions for versioning,
and splits the remainder between TParseContextBase (sharable across parsers)
and TParseContext (now the GLSL-specific part).
Now extensions required by preprocessor should be checked via
the ppRequireExtensions method. This is more clear and coherent
with the rest of the code.
This patch introduces a new extension, GL_GOOGLE_include_directive,
to enable support #include directives. It depends on the extension
GL_GOOGLE_cpp_style_line_directive.
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.
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.
- 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()
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.

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.
