[RFC v2] Towards an assembler parser for PowerPC

[David Fang]

Hi,

I am very much looking forward to seeing/testing this on svn-trunk.
How close is this effort to making it to trunk?
Is there a public branch I can preview in the mean time?
Will there be 32b support as well?
I'm particularly interested in being able to use PowerPC's AsmParser in 
testing PPCMachObjectWriter (doesn't exist yet).
