 // Default options for AddressSanitizer in various configurations:
-//   strict_memcmp=1 - disable the strict memcmp() checking
-//     (http://crbug.com/178677 and http://crbug.com/178404).
 //   malloc_context_size=5 - limit the size of stack traces collected by ASan
 //     for each malloc/free by 5 frames. These stack traces tend to accumulate
 //     very fast in applications using JIT (v8 in Chrome's case), see
 //     https://code.google.com/p/address-sanitizer/issues/detail?id=177
 //   symbolize=false - disable the in-process symbolization, which isn't 100%
 //     compatible with the existing sandboxes and doesn't make much sense for
 //     stripped official binaries.
 //   legacy_pthread_cond=1 - run in the libpthread 2.2.5 compatibility mode to
 //     work around libGL.so using the obsolete API, see
 //     http://crbug.com/341805. This may break if pthread_cond_t objects are
 //     accessed by both instrumented and non-instrumented binaries (e.g. if
 //     they reside in shared memory). This option is going to be deprecated in
 //     upstream AddressSanitizer and must not be used anywhere except the
 //     official builds.
-//   replace_intrin=0 - do not intercept memcpy(), memmove() and memset() to
-//     work around http://crbug.com/162461 (ASan report in OpenCL on Mac).
 //   check_printf=1 - check the memory accesses to printf (and other formatted
 //     output routines) arguments.
 //   use_sigaltstack=1 - handle signals on an alternate signal stack. Useful
 //     for stack overflow detection.
 //   strip_path_prefix=Release/../../ - prefixes up to and including this
 //     substring will be stripped from source file paths in symbolized reports
 //     (if symbolize=true, which is set when running with LeakSanitizer).
 //   fast_unwind_on_fatal=1 - use the fast (frame-pointer-based) stack unwinder
 //     to print error reports. V8 doesn't generate debug info for the JIT code,
 //     so the slow unwinder may not work properly.
 //   detect_stack_use_after_return=1 - use fake stack to delay the reuse of
 //     stack allocations and detect stack-use-after-return errors.
-//   detect_container_overflow=0 - do not detect overflows in containers
-//     until crbug.com/459632 is fixed.
