From e4ed2fa0b64d29cb1864d7eeab7779fd738d4fdf Mon Sep 17 00:00:00 2001 From: Michael Jeanson Date: Fri, 11 Dec 2020 13:52:10 -0500 Subject: [PATCH] Don't force a target and optimization level on ARMv7 We shouldn't force a specific target cpu for the compiler on ARMv7 but let the system or the user choose it. If some of our code depends on a specific target CPU features, it should be compile tested. Also remove the default optimisation level of O1, it's potentially a workaround to an early armv7 compiler performance problem and anyway most builds will have an optimisation level flag set in the CFLAGS which will override this one.
