Subject: [PATCH v2 3/7] configure: Do not force pie=no for non-x86
Date: Wed, 18 Dec 2019 12:34:37 -1000 [thread overview]
Message-ID: <20191218223441.23852-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20191218223441.23852-1-richard.henderson@linaro.org>
PIE is supported on many other hosts besides x86.
The default for non-x86 is now the same as x86: pie is used
if supported, and may be forced via --enable/--disable-pie.
The original commit (40d6444e91c) said:
"Non-x86 are not changed, as they require TCG changes"
but I think that's wrong -- there's nothing about PIE that
affects TCG one way or another.
Tested on aarch64 (bionic) and ppc64le (centos 7) hosts.
