[Vitaly Buka via Phabricator via cfe-commits]

vitalybuka added inline comments.


================
Comment at: clang/docs/AddressSanitizer.rst:18
+* Use-after-return (clang flag `-fsanitize-address-use-after-return=(always|runtime|never)` default: runtime)
+  * Add runtime flag `ASAN_OPTIONS=detect_stack_use_after_return=1` to enable when compiled with `-fsanitize-address-use-after-return=runtime`)
 * Use-after-scope (clang flag `-fsanitize-address-use-after-scope`)
----------------
Please check that this is formatted reasonable in preview.


================
Comment at: clang/docs/ClangCommandLineReference.rst:889
+Valid options are:
+* ``always`` - Always detect use-after-return.  (Code generated and always enabled.)
+* ``runtime`` - Detect use-after-return at runtime if enabled by runtime command line (flag `ASAN_OPTIONS=detect_stack_use_after_return=1`)
----------------
"Code generated and always enabled." is implementation details.
Something like this? 

```
Valid options are:
* ``always`` - Detect use-after-return.
* ``runtime`` - Detect use-after-return with runtime ON/OFF switch (environment variable `ASAN_OPTIONS=detect_stack_use_after_return=1`, default: 0)
* ``never`` - Do not detect use-after-return.
```
