PR optimization/15242
* params.def (PARAM_MAX_GOTO_DUPLICATION_INSNS): New param.
* basic-block.h (duplicate_computed_gotos): Add prototype.
* bb-reorder.c (duplicate_computed_gotos): New function to
duplicate sufficiently small blocks ending in a computed jump.
* passes.c (rest_of_compilation): Call duplicate_computed_gotos
if not optimizing for size.
* cfgcleanup.c (try_crossjump_bb): If not optimizing for size,
never do tail merging for blocks ending in a computed jump.
* doc/invoke.texi: Document the max-goto-duplication-insns param.
