Subject: [PATCH] AArch64: Prioritise init_have_lse_atomics constructor [PR 105708]
Date: Tue, 24 May 2022 16:45:56 +0000 [thread overview]
Message-ID: <DB6PR0801MB18791C9A9C5C8213D039B75683D79@DB6PR0801MB1879.eurprd08.prod.outlook.com> (raw)
Increase the priority of the init_have_lse_atomics constructor so it runs
before other constructors. This improves chances that rr works when LSE
atomics are supported.
Regress and bootstrap pass, OK for commit?
