Subject: [RFC] Function Multi Versioning on Arm
Date: Mon, 18 Jul 2022 10:36:58 +0000	[thread overview]
Message-ID: <45073915-9D33-4097-9CFD-FFBCB9CE1A44@arm.com> (raw)

Hello,

We are going to add Function Multiversioning [1] support to Arm architectures.
The specification is made public as beta[2] to ensure toolchain that follows Arm
C Language Extension will implement it in the same way.

A few tweaks considered to make the developers' life easier.
Since the `target` attribute is used widely on Arm, we would like to introduce a
new attribute `target_version` to avoid confusion and possible deployment
problems. The `target_clones` attribute will be supported too. Also the “default”
version to be made optional.

We are looking for feedback on the specification (reply, github works too).

Thanks so much,
Daniel
