This placates these build warnings: In file included from ../arch/sh/math-emu/math.c:23: ../include/math-emu/single.h:50:21: warning: "__BIG_ENDIAN" is not defined, evaluates to 0 [-Wundef] 50 | #if __BYTE_ORDER == __BIG_ENDIAN In file included from ../arch/sh/math-emu/math.c:24: ../include/math-emu/double.h:59:21: warning: "__BIG_ENDIAN" is not defined, evaluates to 0 [-Wundef] 59 | #if __BYTE_ORDER == __BIG_ENDIAN Fixes: 4b565680d163 ("sh: math-emu support") Signed-off-by: Randy Dunlap <rdunlap@...radead.org> Cc: Yoshinori Sato <ysato@...rs.sourceforge.jp> Cc: Rich Felker <dalias@...c.org> Cc: linux-sh@...r.kernel.org Cc: John Paul Adrian Glaubitz <glaubitz@...sik.fu-berlin.de> Reviewed-by: Geert Uytterhoeven <geert+renesas@...der.be> Tested-by: John Paul Adrian Glaubitz <glaubitz@...sik.fu-berlin.de> --- v2: use same preprocessor method that nds32 does; add Geert's Reviewed-by; renumber patches; add more Cc's; v3: renumber, rebase, and resend; add Tested-by: JPAG; arch/sh/include/asm/sfp-machine.h | 8 ++++++++ 1 file changed, 8 insertions(+) --- linux-next-20211001.orig/arch/sh/include/asm/sfp-machine.h +++ linux-next-20211001/arch/sh/include/asm/sfp-machine.h @@ -13,6 +13,14 @@ #ifndef _SFP_MACHINE_H #define _SFP_MACHINE_H +#ifdef __BIG_ENDIAN__ +#define __BYTE_ORDER __BIG_ENDIAN +#define __LITTLE_ENDIAN 0 +#else +#define __BYTE_ORDER __LITTLE_ENDIAN +#define __BIG_ENDIAN 0 +#endif + #define _FP_W_TYPE_SIZE 32 #define _FP_W_TYPE unsigned long #define _FP_WS_TYPE signed long
