Function Documentation

◆ adjust_before_returns_twice_call()

static void adjust_before_returns_twice_call ( edge e,
gimple * g )
static
Helper function for gsi_safe_insert_before and gsi_safe_insert_seq_before.
Replace SSA_NAME uses in G if they are PHI results of PHIs on E->dest
bb with the corresponding PHI argument from E edge.   

References FOR_EACH_SSA_USE_OPERAND, g, gimple_bb(), gimple_phi_arg_def_from_edge(), r, SET_USE, SSA_NAME_DEF_STMT, SSA_OP_USE, unshare_expr(), update_stmt(), and USE_FROM_PTR.

◆ gimple_find_edge_insert_loc()

static bool gimple_find_edge_insert_loc ( edge e,
gimple_stmt_iterator * gsi,
basic_block * new_bb )
static
Insert the statement pointed-to by GSI into edge E.  Every attempt
is made to place the statement in an existing basic block, but
sometimes that isn't possible.  When it isn't possible, the edge is
split and the statement is added to the new block.

In all cases, the returned *GSI points to the correct location.  The
return value is true if insertion should be done after the location,
or false if it should be done before the location.  If a new basic block
has to be created, it is stored in *NEW_BB.

bool gsi_remove ( gimple_stmt_iterator * i,

Remove the current stmt from the sequence.  The iterator is updated
to point to the next statement.

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.
