version 2.0 05-02-96--------------------* Switched to bfd library. Any supported format (elf, coff, ...) can be used.* The UART devices can be set through -uart1 and -uart2 switches.* Switched to GNU readline.* Added -c option to run batch files at startup* 'reg' command can show different register windows (eg 'reg w3').* Use 'help' for online help on simulator commandsversion 1.8.1 20-01-96--------------------* added -mevrev0 switch to simulate MEC rev.0 bugs in timer and uart* added -iurev0 switch to simulate IU rev.0 jmpl/restore bug* Added sis command 'batch' to run batch filesversion 1.8 30-10-95--------------------* Added s-record support. Use the '-s' switch with sis or the 'load' command.* IU load dependencies are now modelledversion 1.7 30-10-95--------------------* Power-down mode implemented in erc32.c.* Performance display shows the ratio between simulator-time and real-time.version 1.6.2 25-10-95--------------------* The UARTs can now be run at a given speed (simulator time) to bettersimulate the behaviour of interrupt routines. The "true mode" isselected through a compile switch in the makefile.version 1.6 28-09-95--------------------* Major reorganisation of the code. mec.c and mem.c merged into erc32.c.* The load command does NOT longer load the initialised data at an addressdefined by .bdata. This is done in srt0.s using _environ.* Additional MEC functionallity added - software reset, memory accessprotection and waitstate configuration register.* interf.c - a GDB interface added* -v switch (verbose) addedversion 1.5 14-09-95--------------------* Added a instruction trace buffer, enabled through the 'hist' command.* Added a 'perf' command to display statistics such as instruction mix,CPI, FPU holds etc.* Added -nfp switch to disable FPU.* Added -freq switch to set simulated frequency.version 1.4 22-08-95--------------------* A -g is provided for those who have problems with GNU readline().version 1.3 26-07-95--------------------* No major news, just a bug fix release ...version 1.2 13-07-95--------------------* Added setting of IU registers through the 'reg' command. See README.* The GNU readline() function is used for command input. However, actrl-D still kills the simulator ...version 1.1 07-07-95--------------------* Added a 'go' command* Added cycle counting for interrupt overhead.* Function 'get_mem_ptr' takes one more parameter to avoid segmentationfaults if a.out files are loaded outside the simulated memory. See README.* Added user-defined function sim_stop().* Added a reset command. See README.* Implemented buffered output for MEC uarts to improve output speed.
