- For Plexus P/60 and assumably P/35 P/75 P/95's running System V.2
-
- This file outputs assembler source for gas-1.38.1 with the COFF patches
- The patches for gas-1.38.1 to support COFF is on ftp.cs.umb.edu in pub/gnu
- No debugging is supported, due to the fact that the only debugger Plexus
- had was adb *sigh*.
-
- This is configured for label output default by gas as LXXX instead of
- plexus cc/as combination requires .LXXX
