Optimize symbol table initialization #926

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Symbol table builtins are currently related to operators after insertion, in a 
loop that checks all entries. We can instead set them during the insertion. 
There's also opportunity to compact the symbol table initialization by using 
symbolic generic types and vector types.

These patches optimize and simplify the symbol table.

Should follow up with a patch to rename the insertBuiltIn overloads.

Also, operator names can be deduced from operator enums using 
GetOperatorString(), but will have to use constexpr to avoid increasing 
overhead.

Also, check whether the "gl_FragData[gl_MaxDrawBuffers]" declaration is of any 
use.
