? Because if the current function returns through hidden reference, fnargs is
not empty and I'd say it should be not called before processing that hidden
reference argument.
Doesn't seem to change anything on x86_64/i686 on c23-stdarg-*.c, all still
pass,
and in cross to riscv I see difference in the f function.
