I would like to basically ask if it seems to make sense to go this route and
try to get rid of those declarations.
I'm currently working on a new target, ptx, which uses a
pseudo-assembler where functions (even extern ones) need to be declared
with their arguments and return types. With my current code I have to
look at DECL_ARGUMENTS fairly late in the compilation. I'm not quite
sure yet whether the change to delete them will break the backend.
IIRC the PA had similar requirements as well -- in
ASM_DECLARE_FUNCTION_NAME we have to peek at DECL_ARGUMENTS so we can
pass to the assembler & linker which registers hold arguments.
