Joe Ramsay	8b09af572b	aarch64: Avoid redundant MOVs in AdvSIMD F32 logs ... Since the last operation is destructive, the first argument to the FMA also has to be the first argument to the special-case in order to avoid unnecessary MOVs. Reorder arguments and adjust special-case bounds to facilitate this. Reviewed-by: Wilco Dijkstra <Wilco.Dijkstra@arm.com>	2024-09-09 13:03:49 +01:00

Joe Ramsay	cc0d77ba94	aarch64: Add half-width versions of AdvSIMD f32 libmvec routines ... 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.
