The section anchors is a new feature for s390 -with gcc 9, however it breaks our current usage of the 'X' constraint -within the asm goto construct within our jump label implementation. - -Fixing this seems to be non-trivial, therefore (hopefully) temporarily -disable section anchors. We will hopefully have a better solution -before gcc 9 is released, so that this can be removed again. - -Reported-by: Laura Abbott <labbott@redhat.com> -Suggested-by: Ilya Leoshkevich <iii@linux.ibm.com> -Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> ---- - arch/s390/Makefile | 8 ++++++++ - 1 file changed, 8 insertions(+) - -diff --git a/arch/s390/Makefile b/arch/s390/Makefile -index e21053e5e0da..1eac75bc3a29 100644 ---- a/arch/s390/Makefile -+++ b/arch/s390/Makefile -@@ -62,6 +62,14 @@ cflags-y += -Wa,-I$(srctree)/arch/$(ARCH)/include - # - cflags-$(CONFIG_FRAME_POINTER) += -fno-optimize-sibling-calls - -+# -+# Disable section anchors.
