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).

int tarval_snprintf	(	char *	buf,
		size_t	buflen,
		ir_tarval *	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).

Parameters

buf	the output buffer
buflen	the length of the buffer
tv	the tarval
