re PR bootstrap/52808 (LTO bootstrap failed with bootstrap-profiled)
2012-04-03 Richard Guenther <rguenther@suse.de>
PR tree-optimization/52808
* tracer.c (tail_duplicate): Return whether we have duplicated
any block.
(tracer): If we have duplicated any block, cleanup the CFG.
* cfghooks.c (duplicate_block): If we duplicated a loop
header but not its loop, destroy the loop because it now has
multiple entries.
* tree-ssa-threadupdate.c (thread_through_loop_header): Tell
the cfg manipulation routines we are not creating a multiple
entry loop.
* gcc.dg/pr52808.c: New testcase.
