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
