Subject: [PATCH] kexec-tools: Set -fno-PIC on aarch64
Date: Wed, 9 May 2018 23:20:04 -0700 [thread overview]
Message-ID: <20180510062004.8627-1-mingli.yu@windriver.com> (raw)
From: Mingli Yu <Mingli.Yu@windriver.com>
As seen in GCC's gcc/config/aarch64/aarch64.c, -fPIC with large
code model is unsupported. This fixes the "sorry, unimplemented"
errors when building with compilers defaulting to -fPIC.
