Hi Guenter,

commit: 398c7500a1f5f74e207bd2edca1b1721b3cc1f1e MIPS: VDSO: Fix build error
with binutils 2.24 and earlier
date: 6 days ago
config: mips-jmr3927_defconfig (attached as .config)
reproduce:
wget
https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross
-O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 398c7500a1f5f74e207bd2edca1b1721b3cc1f1e
# save the attached .config to linux build tree
make.cross ARCH=mips
All errors (new ones prefixed by >>):
arch/mips/vdso/gettimeofday.c:1:0: error: '-march=r3900' requires '-mfp32'
/*
^
AFAICS this is using the mips cross compiler version 4.9.0 from kernel.org [1],
which in turn uses binutils 2.24. At least this is what make.cross tries to
install.
I downloaded it and used it to compile both the attached configuration as well
as jmr3927_defconfig. Both are building just fine for me. On top of that,
arch/mips/vdso/gettimeofday.c should not build in the first place with binutils
2.24
(and doesn't build for me).
What am I missing ?
