mdk -- History of visible changes. Copyright (C) 2000, jose antonio ortega ruiz See the end for copying conditions. Please send mdk bug reports to jaortega@acm.org. *Version 0.2 ** mixvm provides virtual execution time statistics after each invocation of run or next. ** mixvm can trace instructions as they are executed. tron/troff commands turn off/off instruction tracing. ** mixvm accepts a new command, w2d, which computes the decimal value of a MIX word given as a series of bytes (e.g. - 01 00 34 32 22). ** symbols can be defined at the mixvm prompt with the new command ssym. ** mixvm accepts a new command, weval, which allows the evaluation of MIXAL w-expressions. ** expressions containing strings of successive '*' are now correctly evaluated. ** When using block devices in mixvm, the buffers are now flushed after each OUT operation. *Version 0.1.1 (18/11/00) ** MDK is now compilable in rpm-based linuxes. ** MDK fully compliant with Knuth's specification. In particular, local symbols are now properly handled in special cases such as 3H ORIG 3B instructions. See samples/stress{1,2}.mixal. ** Future references affected by unary minus are accepted with a warning (they are banned in Knuth's specification). Also future refs in EQU directives are now properly handled. See samples/stress{3,4}.mixal. ** When mixvm executes a program and reaches the end of the available memory without encountering a HALT instruction, it halts anyway. *Version 0.1 (31/10/00) ** Initial version ------------------------------------------------------- Copying information: Copyright (C) 2000, jose antonio ortega ruiz Permission is granted to anyone to make or distribute verbatim copies of this document as received, in any medium, provided that the copyright notice and this permission notice are preserved, thus giving the recipient permission to redistribute in turn.
