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.

GLboolean _mesa_parse_arb_program	(	GLcontext *	ctx,
		GLenum	target,
		const GLubyte *	str,
		GLsizei	len,
		struct asm_parser_state *	state
	)

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
	)

Parses and processes instruction suffixes.

Instruction suffixes, such as _SAT, are processed. The relevant bits are set in inst. If suffixes are encountered that are either not known or not supported by the modes and options set in state, zero will be returned.

Returns:

Non-zero on success, zero on failure.

Parses and processes instruction suffixes.
