--------------------
|
|
01e,18may04,jmp fixed instrI86.h reference.
|
|
01d,07apr04,jmp adapted to share trcArchLib between VxSim/i86 and i86 arches.
|
|
01c,11feb04,elg Add syscall instruction size macro.
|
|
01b,09feb04,jeg added DSM() macro definition
|
|
01a,29apr98,cym written based on x86 version.
