Use the `__visible` macro to declare entires and lists declared by ll_entry_declare() and ll_entry_declare_list() externally visible, so that when building with LTO the compiler does not optimize this data away.
__visible is defined like this:
/*
- Optional: not supported by clang
- gcc: https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-ext...
*/ #if __has_attribute(__externally_visible__) # define __visible __attribute__((__externally_visible__)) #else # define __visible #endif
It says clang does not support this. So what about clang?

Regards, Bin
Bin, this is already changed to something different on my github. I will send new version once I am satisfied with CI tests.
