* gimple-iterator.c (gsi_start_edge): New function.
* gimple-iterator.h (gsi_start_edge): Declare.
* tree-sra.c (single_non_eh_succ): New function.
(disqualify_ops_if_throwing_stmt): Renamed to
disqualify_if_bad_bb_terminating_stmt. Allow throwing statements
having one non-EH successor BB.
(sra_modify_expr): If stmt ends bb, use single non-EH successor to
generate loads into replacements.
(sra_modify_assign): Likewise and and also use the simple path for
such statements.
(sra_modify_function_body): Commit statements on edges.
testsuite/
* gnat.dg/opt34.adb: New.
* gnat.dg/opt34_pkg.ads: Likewise.
