From 88e25f47696777d7e60737cd48095e7722a0145e Mon Sep 17 00:00:00 2001 From: Sam Tebbs Date: Thu, 16 Aug 2018 09:43:58 +0000 Subject: [PATCH] [aarch64] Make common aarch64 options target-dependent This patch replaces the "Common" attribute in some aarch64 options with "Target" to make them target-dependent. This doesn't affect their behaviour or how they are documented with "--help", but does mean that they follow the option specification that target-specific options are given the "Target" attribute. Tested by ensuring the changed options are still accepted as before and that they aren't invokable from an invalid target. Bootstrapped and regression tested on aarch64-none-elf with ... regressions. 2018-08-16 Sam Tebbs * config/aarch64/aarch64.opt (mlow-precision-recip-sqrt) (mlow-precision-sqrt, mlow-precision-div, mverbose-cost-dump): Replace "Common" with "Target".
