Subject: Bug#865059: gcc-7: Please temporarily build with
--disable-libcilkrts on sparc64
We're currently observing that the gcc-7 testsuite is crashing the kernel
on the buildds when building with many parallel jobs (>= 16).
It turned out that the offending test is cilkplus and until the kernel
has been fixed, please make sure to build gcc-7 on sparc* with cilk
disabled, e.g. by passing --disable-libcilkrts to configure:
ifneq (,$(findstring sparc64-linux,$(DEB_TARGET_GNU_TYPE)))
CONFARGS += --with-cpu-32=ultrasparc --disable-libcilkrts
CONFARGS += --enable-targets=all
Not sure whether sparc64 should also be removed from rules.defs:cilkrts_archs
for now but I have done that now just to be safe.
We'll let you know once the issue has been fixed in the kernel and
libcilkrts can be enabled again.
