Subject: [PATCH][Binutils]AArch64 Enable FP16 by default for Armv9-A.
Date: Mon, 16 May 2022 17:10:11 +0100 [thread overview]
Message-ID: <patch-15727-tamar@arm.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 1035 bytes --]
Hi All,
In Armv9-A SVE is mandatory, and for SVE FP16 is mandatory. This fixes a disconnect
between GCC and binutils where GCC has FP16 on by default and gas doesn't.
build on native hardware and regtested on aarch64-none-linux-gnu and no issues.
Ok for master? and for backport to binutils-2.38?
Thanks,
Tamar
