Hi,
I was not aware that CONFIG_JUMP_LABEL Kconfig setting depends on the
support of asm-goto.
Currently, I am doing experiments with clang-7 and a snapshot of
clang-8 on Linux/x86.
These compilers have no asm-goto support.
What is your recommendation for Linux >= v4.20?
I am asking as it is

Currently, CONFIG_JUMP_LABEL just means "I _want_ to use jump label".
The jump label is controlled by HAVE_JUMP_LABEL, which is defined
like this:
#if defined(CC_HAVE_ASM_GOTO) && defined(CONFIG_JUMP_LABEL)
# define HAVE_JUMP_LABEL
#endif
We can improve this by testing 'asm goto' support
