[PR 80622] Treat const pools as initialized in SRA
2017-05-04 Martin Jambor <mjambor@suse.cz>
PR tree-optimization/80622
* tree-sra.c (comes_initialized_p): New function.
(build_accesses_from_assign): Only set write lazily when
comes_initialized_p is false.
(analyze_access_subtree): Use comes_initialized_p.
(propagate_subaccesses_across_link): Assert !comes_initialized_p
instead of testing for PARM_DECL.
testsuite/
* gcc.dg/tree-ssa/pr80622.c: New test.
