@ -744,11 +744,11 @@ Arm and AArch64 Support in Clang
- ``-march`` values for targeting armv2, armv2A, armv3 and armv3M have been removed.
Their presence gave the impression that Clang can correctly generate code for
them, which it cannot.
- Add driver and tuning support for Neoverse V2 via the flag ``-mcpu=neoverse-v2``.
Native detection is also supported via ``-mcpu=native``.
- Support has been added for the following processors (-mcpu identifiers in parenthesis):
* Arm Cortex-A715 (cortex-a715).
* Arm Cortex-X3 (cortex-x3).
* Arm Neoverse V2 (neoverse-v2)
Floating Point Support in Clang
