Subject: [PATCH] mips: vdso: Explicitly use -fno-asynchronous-unwind-tables
Date: Thu, 26 Jan 2017 15:34:08 +0100 [thread overview]
Message-ID: <20170126143408.2456-1-alexander.sverdlin@nokia.com> (raw)
Message-ID: <20170126143408.mgBirYaVK5Ek35mkyZNF2wdlAR82MbiyfHjvW1i5jls@z> (raw)
From: Robert Schiele <rschiele@gmail.com>
Not every toolchain has -fno-asynchronous-unwind-tables per default on MIPS.
This patch specifies the necessary option explicitly for VDSO library build.
This prevents the following build failure:
GENVDSO arch/mips/vdso/vdso-image.c
arch/mips/vdso/genvdso: 'arch/mips/vdso/vdso.so.dbg' contains relocation sections
.../arch/mips/vdso/Makefile:84: recipe for target 'arch/mips/vdso/vdso-image.c' failed
