void add_stmt_to_eh_lp	(	gimple	,
		int
	)

int lookup_stmt_eh_lp ( gimple )

int lookup_stmt_eh_lp_fn	(	struct function *	,
		gimple
	)

bool make_eh_dispatch_edges ( gimple )

void make_eh_edges ( gimple )

bool maybe_clean_eh_stmt ( gimple )

bool maybe_clean_eh_stmt_fn	(	struct function *	,
		gimple
	)

bool maybe_clean_or_replace_eh_stmt	(	gimple	,
		gimple
	)

bool maybe_duplicate_eh_stmt	(	gimple	,
		gimple
	)

bool maybe_duplicate_eh_stmt_fn	(	struct function *	new_fun,
		gimple	new_stmt,
		struct function *	old_fun,
		gimple	old_stmt,
		struct pointer_map_t *	map,
		int	default_lp_nr
	)

Given a statement OLD_STMT in OLD_FUN and a duplicate statement NEW_STMT in NEW_FUN, copy the EH table data from OLD_STMT to NEW_STMT. The MAP operand is the return value of duplicate_eh_regions.

void maybe_remove_unreachable_handlers ( void )

Remove unreachable handlers if any landing pads have been removed after last ehcleanup pass (due to gimple_purge_dead_eh_edges).

bool operation_could_trap_helper_p	(	enum tree_code	op,
		bool	fp_operation,
		bool	honor_trapv,
		bool	honor_nans,
		bool	honor_snans,
		tree	divisor,
		bool *	handled
	)

Helper function for operation_could_trap_p and stmt_could_throw_p.

     Some floating point comparisons may trap.

     Conversion of floating point might trap.

     These operations don't trap with floating point.

     Any floating arithmetic may trap.

     Constructing an object cannot trap.

     Any floating arithmetic may trap.

bool operation_could_trap_p	(	enum tree_code	op,
		bool	fp_operation,
		bool	honor_trapv,
		tree	divisor
	)

Return true if operation OP may trap. FP_OPERATION is true if OP is applied on floating-point values. HONOR_TRAPV is true if OP is applied on integer type operands that may trap. If OP is a division operator, DIVISOR contains the value of the divisor.

void redirect_eh_dispatch_edge	(	gimple	,
		edge	,
		basic_block
	)

edge redirect_eh_edge	(	edge	,
		basic_block
	)

bool remove_stmt_from_eh_lp ( gimple )

bool remove_stmt_from_eh_lp_fn	(	struct function *	,
		gimple
	)

bool stmt_can_throw_external ( gimple )

bool stmt_can_throw_internal ( gimple )

bool stmt_could_throw_p ( gimple )

bool tree_could_throw_p ( tree )

bool tree_could_trap_p ( tree )
