Right, as I wrote in RFC "solution is wrong", I knew it, just didn't get any feedback on how to do it correctly. Are you suggesting something like this? diff --git a/kernel/gcov/Kconfig b/kernel/gcov/Kconfig index 3110c77230c7..bc0e355f64aa 100644 --- a/kernel/gcov/Kconfig +++ b/kernel/gcov/Kconfig @@ -3,7 +3,7 @@ menu "GCOV-based kernel profiling" config GCOV_KERNEL bool "Enable gcov-based kernel profiling" - depends on DEBUG_FS + depends on DEBUG_FS && (GCC_VERSION >= XXX && GCC_VERSION < YYY) select CONSTRUCTORS if !UML default n help ~ Thanks > > Linus
