gcc : ChangeLog.tree-ssa tree-cfg.c tree-flow.h
tree-ssa-dom.c
Log message:
* tree-cfg.c (cleanup_control_flow): Pass last statement down to
cleanup_cond_expr_graph and cleanup_switch_expr_graph.
(cleanup_cond_expr_graph): Accept statement from caller and
use it. Return nonzero if the predicate was constant. No longer
static.
(cleanup_switch_expr_graph): Similarly.
(disconnect_unreachable_case_labels): Similarly, except that it
is still static.
* tree-flow.h (cleanup_cond_expr_graph): Prototype.
(cleanup_switch_expr_graph): Similarly.
* tree-ssa-dom.c (optimize_stmt): Also optimize the condition
in a SWITCH_EXPR. Use COND_EXPR_COND and SWITCH_COND to get
conditions instead of relying upon known operand positions.
Use cleanup_cond_expr_graph and cleanup_switch_expr_graph rather
than open coding equivalents.
(lookup_avail_expr): Handle SWITCH_EXPRs. Use COND_EXPR_COND and
SWITCH_COND to get conditions instead of relying upon known
operand positions.
(avail_expr_hash, avail_expr_eq): Similarly.
