From bfd77145f35c3deafe57e9eb67fff4ccffdaef6e Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 5 Aug 2019 15:11:15 -0700 Subject: Makefile: Convert -Wimplicit-fallthrough=3 to just -Wimplicit-fallthrough for clang A compilation -Wimplicit-fallthrough warning was enabled by commit a035d552a93b ("Makefile: Globally enable fall-through warning") Even though clang 10.0.0 does not currently support this warning without a patch, clang currently does not support a value for this option. Link: https://bugs.llvm.org/show_bug.cgi?id=39382 The gcc default for this warning is 3 so removing the =3 has no effect for gcc and enables the warning for patched versions of clang. Also remove the =3 from an existing use in a parisc Makefile: arch/parisc/math-emu/Makefile Signed-off-by: Joe Perches Reviewed-and-tested-by: Nathan Chancellor Cc: Gustavo A. R.
