tstDisasm-2.cpp@ 41668

Last change on this file since 41668 was 41668, checked in by vboxsync, 13 years ago
DIS,DIS-users: Drop the operand/parameter formatting during instruction parsing. The desired formatter can do this afterwards if desired. Should save time + size. (DISCPUSTATE is now 256 bytes here on 64-bit linux, was ~406 yesterday.)
