| |
When building with W=1:
arch/m68k/lib/muldi3.c:82:1: warning: no previous prototype for ‘__muldi3’ [-Wmissing-prototypes] 82 | __muldi3 (DItype u, DItype v) | ^~~~~~~~
Fix this by including <linux/libgcc.h>.
Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> --- To bequeued in the m68k for-v6.7 branch.
Missed before, as "make arch/m68k/" does not (re)build arch/m68k/lib/?
arch/m68k/Makefile has:
libs-y += arch/m68k/lib/
while all the other subdirs use "obj-y". --- arch/m68k/lib/muldi3.c | 1 + 1 file changed, 1 insertion(+)
