* common.opt: Split up -fisolate-erroneous-paths into
-fisolate-erroneous-paths-dereference and
-fisolate-erroneous-paths-attribute.
* invoke.texi: Corresponding changes.
* gimple.c (infer_nonnull_range): Add and use new arguments
to control what kind of statements can be used to infer a
non-null range.
* gimple.h (infer_nonnull_range): Update prototype.
* tree-vrp.c (infer_value_range): Corresponding changes.
* opts.c (default_options_table): Update due to option split.
* gimple-ssa-isolate-paths.c: Fix trailing whitespace.
(find_implicit_erroneous_behaviour): Pass additional arguments
to infer_nonnull_range.
(find_explicit_erroneous_behaviour): Similarly.
(gate_isolate_erroneous_paths): Check both of the new
options.
testsuite/
* gcc.dg/pr38984.c: Use -fno-isolate-erroneous-paths-dereference.
* gcc.dg/tree-ssa/isolate-2.c: Explicitly turn on
-fisolate-erroneous-paths-attribute.
* gcc.dg/tree-ssa/isolate-4.c: Likewise.
