From 8811c8f495557bb05a65d2c09eb529e2675b6a57 Mon Sep 17 00:00:00 2001 From: Thomas Preud'homme Date: Tue, 20 Feb 2018 12:48:50 +0000 Subject: [PATCH] Clarify .arch_extension possible values Documentation for .arch_extension says it accepts the same architectural extensions as those accepted by -mcpu. Given the name and the fact that -march for obvious reason also accept the same extensions, I believe it's worth mentioning that it accepts the same extensions as both -march and -mcpu.
