>Subject: [PATCH] builtools: Make abi_gen.sh less prone to errors
>
>The mold linker has more hidden symbols and we would need to filter them out
>with nm, where objdump tells us which symbols are actually hidden. So we just
>need to filter out whatever is hidden.
>
>The use of awk makes it also easier to get what we want.
