In-Reply-To: Message from Moritz Thomas <motho@gmx.net> of "Wed, 19 Jan 2000 11:38:57 +0100." <l03130300b4ab42c57934@[213.6.57.225]>
Why does each application/library define its own, incorrect
definition of byte-reversed instructions? Doesn't some Linux/PPC header
file define this once in a awy that could be imported by others?
One cannot use "r" as a constraint for a base address, that is
what the GCC PowerPC port defines "b" for. The load/store instruction
patterns in the GCC PowerPC machine description file use a different
constraint letter for the base address, and anyone writing inlined
assembly -- especially loads and stores -- should browse the GCC machine
description.
