Detailed Description

Describes a pair of references used in an access by built-in
functions like memcpy.

Constructor & Destructor Documentation

◆ access_data() [1/2]

access_data::access_data	(	range_query *	query,
		gimple *	stmt,
		access_mode	mode,
		tree	maxwrite = NULL_TREE,
		bool	minwrite = false,
		tree	maxread = NULL_TREE,
		bool	minread = false )

Set the access to at most MAXWRITE and MAXREAD bytes, and at least 1
when MINWRITE or MINREAD, respectively, is set.

References dst_bndrng, ggc_alloc(), set_bound(), src_bndrng, and stmt.

◆ access_data() [2/2]

access_data::access_data	(	range_query *	query,
		tree	expr,
		access_mode	mode,
		tree	maxwrite = NULL_TREE,
		bool	minwrite = false,
		tree	maxread = NULL_TREE,
		bool	minread = false )

Set the access to at most MAXWRITE and MAXREAD bytes, and at least 1
when MINWRITE or MINREAD, respectively, is set.

References dst_bndrng, ggc_alloc(), set_bound(), src_bndrng, and stmt.

◆ set_bound()

void access_data::set_bound	(	offset_int	bndrng[2],
