--- Comment #7 from ktkachov at gcc dot gnu.org --- Yes, GCC could be more helpful here. The intrinsics and their use is documented in the ACLE document: https://github.com/ARM-software/acle/blob/main/main/acle.md#random-number-generation-intrinsics There is work ongoing to augument it with more user-friendly information about compiler flags, but GCC could keep track of the options used to gate these builtins/intrinsics and report a hint
