◆ gsi_insert_before_without_update()

void gsi_insert_before_without_update	(	gimple_stmt_iterator *	i,

Insert statement STMT before the statement pointed-to by iterator I.
M specifies how to update iterator I after insertion (see enum
gsi_iterator_update).

This function does not scan for new operands.  It is provided for
the use of the gimplifier, which manipulates statements for which
def/use information has not yet been constructed.  Most callers
should use gsi_insert_before.

REMOVE_PERMANENTLY is true when the statement is going to be removed
from the IL and not reinserted elsewhere.  In that case we remove the
statement pointed to by iterator I from the EH tables, and free its
operand caches.  Otherwise we do not modify this information.  Returns
true whether EH edge cleanup is required.
