Detailed Description

Function Documentation

◆ ir_fprintf()

int ir_fprintf	(	FILE *	f,
		const char *	fmt,
			... )

See also: ir_printf.

◆ ir_obst_vprintf()

int ir_obst_vprintf	(	struct obstack *	obst,
		const char *	fmt,
		va_list	args )

See also: ir_printf.

◆ ir_printf()

int ir_printf	(	const char *	fmt,
			... )

A string formatting routine for ir objects.

Parameters

fmt	The format string.

This function rudimentary implements a kind of printf(3) for ir nodes and adds the following additional conversion specifiers.

%t A type name.
%e An entity name.
%E An entity ld name.
%T A tarval.
%n A full description of a node.
%O The opcode name of an ir node.
%N The node number of an ir node.
%m The mode name of an ir mode.
%B The block node number of the nodes block.
%I An ident.
%D Print as many white spaces as given in the parameter.
%G A debug info (if available) from the given ir node.
%B A bitset.
%F A Firm object (automatically detected).

◆ ir_snprintf()

int ir_snprintf	(	char *	buf,
		size_t	n,
		const char *	fmt,
			... )

See also: ir_printf.

◆ ir_vfprintf()

int ir_vfprintf	(	FILE *	f,
		const char *	fmt,
		va_list	args )

See also: ir_printf.

◆ ir_vprintf()

int ir_vprintf	(	const char *	fmt,
		va_list	args )

See also: ir_printf.

◆ ir_vsnprintf()

int ir_vsnprintf	(	char *	buf,
		size_t	len,
		const char *	fmt,
		va_list	args )

See also: ir_printf.

◆ tarval_snprintf()

int tarval_snprintf	(	char *	buf,
		size_t	buflen,
		ir_tarval const *	tv )

Output a tarval in human readable format to a string buffer.

This function is meant for debugging purposes, the string is formated in a way easily understandable for humans. You should not use this for storage or output for other tools (like assemblers), use get_tarval_sub_bits() for these cases.

The final string in "buf" is guaranteed to be zero-terminated (if buflen is at least 1).
