Ian Romanick	ac4fdc255b	Add query to determine whether a name was declared at this scope ... This will be used to prevent a variable and a function with the same name from being declared. As a side effect, the calls to add_{type,name,function} should never fail.	2010-03-19 15:37:01 -07:00
Ian Romanick	38395c1aad	Use separate namespaces for types, variables, and functions ... This will allow types and their constructors to be easily stored in the same symbol table. This does add a potential problem that a shader could declare a variable and a function with the same name. This appears to be forbidden by the GLSL spec.	2010-03-19 15:34:13 -07:00
Ian Romanick	82de85e264	Add a GLSL-specific facade to _mesa_symbol_table ... This adds some type saftey and will enable elimination of a bunch of type casts and other ugly crap in the code.	2010-03-19 11:43:36 -07:00
