Subject: [PATCH v2 06/11] tests/tcg/i386: force -fno-pie for test-i386
Date: Thu, 1 Apr 2021 11:25:25 +0100 [thread overview]
Message-ID: <20210401102530.12030-7-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210401102530.12030-1-alex.bennee@linaro.org>
The containerised compiler defaults to no-pie anyway but if we are
relying on the users installed cross compiler we need to check it
works for building 16 bit code first.
