* aarch64: Add half-width versions of AdvSIMD f32 libmvec routinesJoe Ramsay2023-12-201-1/+3
| | | | | | | | | | | Compilers may emit calls to 'half-width' routines (two-lane single-precision variants). These have been added in the form of wrappers around the full-width versions, where the low half of the vector is simply duplicated. This will perform poorly when one lane triggers the special-case handler, as there will be a redundant call to the scalar version, however this is expected to be rare at Ofast.

* aarch64: Add vector implementations of exp routinesJoe Ramsay2023-06-301-0/+133
Optimised implementations for single and double precision, Advanced SIMD and SVE, copied from Arm Optimized Routines. As previously, data tables are used via a barrier to prevent overly aggressive constant inlining. Special-case handlers are marked NOINLINE to avoid incurring the penalty of switching call standards unnecessarily. Reviewed-by: Szabolcs Nagy <szabolcs.nagy@arm.com>
