Compare operations will do a literal compare of basic string values unless the all of each string contains numeric data. If numeric data is there then a numeric comparison will be made. For example:
If "+1" == "1" echo equal
will display equal, while the simple string comparison will be not-equal.
- EXPECT will now tolerate a HALTAFTER=n parameter which delay the simulator stopping execution for n instructions. Unpredictable behavior will happen if multiple EXPECT conditions see matching data before the first actualy halt occurs.
- SEND has an AFTER=n argument which delays the initial stuffed data from being input for at least n instructions. It also has a DELAY=m argument which specifies the minimum number of instructions which must execute between stuffed input data.
- Changed run_cmd() to no longer clear pending breakpoint actions before starting instruction execution.
- Added a -Q switch to the commands which dispatch through run_cmd() (RUN, STEP, NEXT, GO, BOOT, etc.). This switch will suppress status output when execution stops. This will allow sequences of breakpoint action commands to silently execute when needed.
Ideas based on Dave Bryan's console halt efforts.
sim> SEND {<mux>:line} {DELAY=n,}"string"
Where <mux> is the name of the device pointed to by the TMXR structure. If <mux>:line isn't specified, then the console device is implicitly being referenced.
Delay is optional and once set persists for subsequent SEND operations to the same device. Delay defaults to 1000. The DELAY value is a minimum number of instructions which must execute before the next character in the provided string will be injected to the console port. The DELAY value has effect between the characters delivered as well. "string" requires quotes and within the quoted string, common C escape character syntax is available (\r\r\t, etc.).
Each device (console, and each line in each mux) has a separate value for DELAY.
An arbitrary number of 'expect' conditions can be defined. The command syntax is:
sim> EXPECT {<mux>:line} {[cnt]} "matchstring" {actioncommand {; actioncommand ...}}
Where <mux> is the name of the device pointed to by the TMXR structure. If <mux>:line isn't specified, then the console device is implicitly being referenced.
"matchstring" requires quotes and within the quoted string, common C escape character syntax is available (\r\r\t, etc.). The quotes used can be single or double quotes, but the closing quote must match the opening quote. The match string might be extended to allow the use of perl style regular expressions in the "matchstring" when a -R switch is specified on the command line.
sim> EXPECT "Enter Color: " SEND "Red\r"; g
A specific 'expect' condition can be removed with:
sim> NOEXPECT {<mux>:line} "matchstring"
All 'expect' conditions can be removed with:
sim> NOEXPECT {<mux>:line}
'expect' conditions can be examined with:
sim> SHOW EXPECT {<mux>:line}
Expect rules are one-shots (i.e. they disappear once a match has occurred) unless they are explicitly described as persistent with the -P switch.
The -C switch is available when defining expect rules. The effect of a rule defined with the -C flag is that when an expect match occurs for that rule, ALL rules are cleared for that device (console or <mux>:line).
Removed the recently added SET CPU IDLE=SYSV since any SET CPU IDLE command will work for SysV. Existing configurations probably did a SET CPU IDLE=32V which works fine now.
Changed things based on the realization that ANY branch instruction which tests memory and then branches to itself is an idle loop if the branch is taken. This is without regard to address space, access mode, If interrupts are disabled, then it is a hung system and the simulation should halt.
Find the header and library paths with findpaths.
We need -lnetwork for sockets.
We do support pthread, it's in libroot.
We do support dlopen, it's in libroot.
