Summary: [6 Regression] CSiBE size regression
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

+ * bb-reorder.c (reorder_basic_blocks): Use the algorithm selected
+ with flag_reorder_blocks_algorithm.
+ * common.opt (freorder-blocks-algorithm=): New flag.
+ (reorder_blocks_algorithm): New enum.
+ * flag-types.h (reorder_blocks_algorithm): New enum.
+ * opts.c (default_options_table): Use -freorder-blocks at -O1 and up,
+ and -freorder-blocks-algorithm=stc at -O2 and up (not at -Os).
The size regression is from 3562398 bytes to 3617915 bytes.
