Function Documentation

int _mesa_ARBfp_parse_option	(	struct asm_parser_state *	state,
		const char *	option
	)

Parses and processes an option string to an ARB fragment program.

Returns:

Non-zero on success, zero on failure.

int _mesa_ARBvp_parse_option	(	struct asm_parser_state *	state,
		const char *	option
	)

Parses and processes an option string to an ARB vertex program.

Returns:

Non-zero on success, zero on failure.

int _mesa_parse_cc

(

const char *

s

)

Parses a condition code name.

The condition code names (e.g., LT, GT, NE) were added to assembly shaders with the GL_NV_fragment_program_option extension. This function converts a string representation into one of the COND_ macros.

Returns:

One of the COND_ macros defined in prog_instruction.h on success or zero on failure.

int _mesa_parse_instruction_suffix	(	const struct asm_parser_state *	state,
		const char *	suffix,
		struct prog_instruction *	inst
	)

Extra assembly-level parser routines.

Parses and processes instruction suffixes.
