Subject: [PATCH 6/6] x86: Fix -Os build (BZ #29576)
Date: Wed, 21 Sep 2022 10:51:08 -0300 [thread overview]
Message-ID: <20220921135108.3324737-7-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20220921135108.3324737-1-adhemerval.zanella@linaro.org>
The compiler might transform __stpcpy calls (which are routed to
__builtin_stpcpy as an optimization) to strcpy and x86_64 strcpy
multiarch implementation does not build any working symbol due
ISA_SHOULD_BUILD not being evaluated for IS_IN(rtld).
Checked on x86_64-linux-gnu.
