Subject: [PATCH v2 4/6] ARM: drop no-thumb-interwork in EABI mode
Date: Sun, 25 Mar 2018 20:09:57 +0200 [thread overview]
Message-ID: <20180325180959.28008-5-stefan@agner.ch> (raw)
In-Reply-To: <20180325180959.28008-1-stefan@agner.ch>
According to GCC documentation -m(no-)thumb-interwork is
meaningless in AAPCS configurations. Also clang does not
support the flag:
clang-5.0: error: unknown argument: '-mno-thumb-interwork'
Just drop -mno-thumb-interwork in AEABI configuration.
