From d4e60453266b95b9dc19e0af2a819617e556bc4e Mon Sep 17 00:00:00 2001 From: Cesar Eduardo Barros Date: Thu, 9 Jul 2020 19:11:02 -0300 Subject: [PATCH] Restore gcc check in mips asm/unroll.h While raising the gcc version requirement to 4.9, the compile-time check in the unroll macro was accidentally changed from being used on gcc and clang to being used on clang only. Restore the gcc check, changing it from "gcc >= 4.7" to "all gcc". [ We should probably remove this all entirely: if we remove the check for CLANG, then the check for GCC can go away. Older versions of clang are not really appropriate or supported for kernel builds - Linus ] Fixes: 6ec4476ac825 ("Raise gcc version requirement to 4.9") Signed-off-by: Cesar Eduardo Barros Signed-off-by: Linus Torvalds --- arch/mips/include/asm/unroll.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/arch/mips/include/asm/unroll.h b/arch/mips/include/asm/unroll.h index 8ed660adc84f..49009319ac2c 100644 --- a/arch/mips/include/asm/unroll.h +++ b/arch/mips/include/asm/unroll.h @@ -25,7 +25,8 @@ * generate reasonable code for the switch statement, \ * so we skip the sanity check for those compilers. \ */ \ - BUILD_BUG_ON((CONFIG_CLANG_VERSION >= 80000) && \ + BUILD_BUG_ON((CONFIG_CC_IS_GCC || \ + CONFIG_CLANG_VERSION >= 80000) && \ !__builtin_constant_p(times)); \ \ switch (times) { \
