Yes, libffi has been around for quite a while, so I'm sure that there's a
lot of projects that depend on it. Looking at the assembly code for
plan9/x86 that comes with dyncall, might be helpful for adding plan9
support to libffi, as well, though - at the very core, both libraries do
similar things.
About converting GAS ASM to Plan9 ASM - I don't know of any
library/program that does this, per se, but dyncall has a little helper
'lib' called portasm, that tries to abstract platform syntax away using
the C preprocessor.
Maybe that's a good start for rolling your own, as well...
http://dyncall.org/svn/dyncall/trunk/dyncall/portasm/
It doesn't come with any documentation, though, as it is used internally,
but yes... it's just C preprocessor...
Hope this helps,
Tassilo
