Do you mean macros that generate both the instruction and the CFI or separate? The major disadvantage of doing it together in a single macro is that it is not really readable for any assembler programmer anymore, but starts becoming a Linux specific assembler language. Likely not a good thing for maintenance. anyone who wants to know the real assembler would need to read objdump -S output, which is not nice.
Perhaps it would be a reasonable readability improvement to just use shorter cfi macros which are not shouted?
