64716dad74 makefile: Fix MinGW build to allow C++ compiles 2016-05-16 16:17:22 -07:00
Mark Pizzolato
5531ccb175 ALL: Massive 'const' cleanup 
These changes facilitate more robust parameter type checking and helps
to identify unexpected coding errors.

Most simulators can now also be compiled with a C++ compiler without
warnings.

Additionally, these changes have also been configured to facilitate easier
backporting of simulator and device simulation modules to run under the
simh v3.9+ SCP framework.

f1d9e749f6 DISK: Add disk content validation checking 
When creating a new disk image the new disk image can be populated with
unique data in each sector.  The data is the logical block address of the sector
in a 4 byte little-endian value.  This is enabled when the -I switch is specified
on the ATTACH command.  To leverage this, a -K flag is interpreted on the
ATTACH command which will validate the entire disk contents actually
contains the expected value at attach time and also will validate that any data
written to the disk during simulator operation also contains the same logical
block address values.

f60390ce89 Compiler suggested cleanup 
Cast the results of unit pointer subtraction to int so it can be printed with a %d format specifier.

73d7aee71f SCP: Add printf style format argument validation for all functions which take printf arguments. 
These include: sim_printf(), sim_messagef(), Fprint() and sim_debug().

Fix current use of these functions which had invalid arguments.

6ce8d99cd8 SCP: Added generic output routine sim_printf to output to stdout and sim_log (and sim_deb when enabled) 
The goals here being to simplify calling code while getting consistent output delivered everywhere it may be useful.

Modified most places which explicitly used sim_log or merely called printf to now avoid doing that and merely call sim_printf().
