Subject: [PATCH 13/15] arm: Add pacbti related multilib support for armv8.1-m.main.
Date: Fri, 12 Aug 2022 17:10:55 +0000	[thread overview]
Message-ID: <VE1PR08MB48932215795BF896E12A521E9B679@VE1PR08MB4893.eurprd08.prod.outlook.com> (raw)

 Hi,

This patch supports following -march/-mbranch-protection combination by linking them
to existing pacbti multilibs.

$ -march=armv8.1-m.main+pacbti+fp.dp+mve.fp -mbranch-protection=standard -mfloat-abi=hard -mthumb
$ -march=armv8.1-m.main+pacbti+fp.dp+mve -mbranch-protection=standard -mfloat-abi=hard -mthumb
$ -march=armv8.1-m.main+dsp+pacbti+fp.dp -mbranch-protection=standard -mfloat-abi=hard -mthumb

Regression tested on arm-none-eabi and bootstrapped on arm-none-linux-gnueabihf.

Ok for master?

Regards,
Srinath.

gcc/ChangeLog:

2022-08-12  Srinath Parvathaneni  <srinath.parvathaneni@arm.com>
