Make SRA re-construct orginal memory accesses when easy
2019-06-06 Martin Jambor <mjam...@suse.cz>
* tree-sra.c (struct access): New field grp_same_access_path.
(dump_access): Dump it.
(build_reconstructed_reference): New function.
(build_ref_for_model): Use it if possible.
(path_comparable_for_same_access): New function.
(same_access_path_p): Likewise.
(sort_and_splice_var_accesses): Set the new flag.
(analyze_access_subtree): Likewise.
(propagate_subaccesses_across_link): Propagate zero value of the
new
flag down the access tree.
testsuite/
* gcc.dg/tree-ssa/alias-access-path-1.c: Remove -fno-tree-sra
option.
* gcc.dg/tree-ssa/ssa-dse-26.c: Disable FRE.
* testsuite/gnat.dg/opt39.adb: Adjust scan dump.
