Subject: klibc: Need psABIs and #defines
Date: 9 Aug 2002 15:43:23 -0700 [thread overview]
Message-ID: <aj1gib$6vd$1@cesium.transmeta.com> (raw)
Hi all,
I could use some help with portability for non-x86 platforms. In
particular, I need to figure out how to make crt0.[cS] to work on
various platforms, which unfortunately doesn't seem to be all that
obvious. Unfortunately the SysV ABI creators didn't do the obvious
thing, which would have been to call _start() with its parameters
using the standard C calling sequence; instead, each platform seems to
put things on the stack in various ways (the sparc, for example, needs
a register window save area.)
a) If you'd be willing to write crt0.c/crt0.S for any platform, let me
know.
b) If you know where to get psABIs other than x86, x86-64, mips32 and
sparc32, let me know.
c) If you know what #ifdefs one can use to test for any platform, let
me know...
