gcc : ChangeLog flow.c
Log message:
* flow.c: Grammar check and clarify a lot of comments.
(try_simplify_condjump): Rename variables to be clearer.
(try_forward_edges): Skip complex and fallthru edges.
Rearrange tests to avoid duplicate checks.
(flow_find_cross_jump): Likewise.
(outgoing_edges_match): Allow match if neither branch has
probability data. Loosen probability match to 5%.
(try_crossjump_to_edge): Hoist repeated indirection into
local variables.
(try_crossjump_bb): Don't check complex edges. Eliminate
redundant crossjump tests.
(try_optimize_cfg): Fix use of bool. Reorganize cheaper
checks before more expensive checks.
