Subject: [PATCH] ARM: Enable frame pointers for arm64
Date: Thu, 9 Mar 2023 14:57:13 +0100 [thread overview]
Message-ID: <20230309135713.3874769-1-s.hauer@pengutronix.de> (raw)
stack unwinding on arm64 depends on framepointers, so enable them.
OSELAS.Toolchain-2022.10.0 now defaults to -fomit-frame-pointer whereas
earlier versions default to -fno-omit-frame-pointer. Fix stack
unwinding for new OSELAS.Toolchain and other toolchains which omit
frame pointers by default.
