    * Updates to constant time C code so that compilers are less likely to use
-     conditional instructions (Clang was observed to use these). Conditional
-     instructions might have an observable difference in timing. Introduce
-     assembly implementations for 32 and 64-bit Arm and for x86 and x86-64,
-     which are guaranteed not to use conditional instructions.

+     Introduce assembly implementations of constant time code for
+     Thumb 1 & Thumb 2, 32-bit Arm, aarch64, x86 and x86-64, which are
