* asan.c (instrument_builtin_call): Really put the length of the PR sanitizer/56330
second source argument into src1_len. * asan.c (get_mem_refs_of_builtin_call): Fix up indentation.
(instrument_mem_region_access): Create conditional even when
the start has been already instrumented. Don't record
conditional instrumentation in the hash table. Update *iter
after second build_check_stmt call.
(instrument_builtin_call): For consistency test != NULL_TREE
in all start checks.
* c-c++-common/asan/memcmp-2.c: New test. * c-c++-common/asan/no-redundant-instrumentation-1.c: Pass
3 instead of sizeof (tab) - 1 as last argument.
* c-c++-common/asan/pr56330.c: New test.
