Revision 984 - (download) (annotate)
Wed Nov 21 19:00:08 2001 UTC (18 years, 7 months ago) by george

  Implemented a complete redesign of MLRISC pseudo-ops. Now there
  ought to never be any question of incompatabilities with
  pseudo-op syntax expected by host assemblers.

  For now, only modules supporting GAS syntax are implemented
  but more should follow, such as MASM, and vendor assembler
  syntax, e.g. IBM as, Sun as, etc.
