Source: gcc-7
Version: 7.1.0-7
Severity: important
User: debian-sparc@lists.debian.org
Usertags: sparc64
Hello!
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
ifeq ($(biarch32),yes)
CONFARGS += --enable-targets=all
endif
endif
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.
Thanks,
Adrian

GCC upstream have patched cilk to fix userspace issues in the test
suite, which also seemingly no longer triggers the kernel bug, so please
cilk enabled. Hopefully we can still get the kernel fixed as the bug is
still lying there waiting, but at least GCC builds should no longer
bring the buildds down.

James
