================
Comment at: clang/docs/ReleaseNotes.rst:760
+- Strict floating point has been enabled for AArch64, which means that
+  ``-ftrapping-math``, ``-frounding-math``, ``-ffp-model=strict``, and
+  ``-ffp-exception-behaviour=<arg>`` are now accepted.

-ftrapping-math and -ffp-model=strict are both driver-only options that are converted into other cc1 options and tested in Driver/fp-model.c. -frounding-math is tested in a target-independent way in the CodeGen/fpconstrained* tests.
