FILE LIST -	    recoverExcSigDemo.cDESCRIPTION -	    tServer task executes functions at low priority (254). serverSend	    funtion is used to send a request to the tServer to execute a	    function at the tServer's  priority.	    First tServer task executes the i() system call to print the summary	    of tShell task. Next an address exception is caused in tServer	    task by trying to execute a funtion at non-aligned word boundry.	    As a result SIGBUS signal is  raised  automatically. Signals	    (setjmp() and longjmp()) are used to allow the tServer task to	    recover gracefully from an address error exception. For more	    information about signals, please refer to sigLib manual pages.RUNNING DEMO -	    Place the recoverExcSigDemo.c file in your <Tornado> dir. Depending	    on the target you have, define the CPU in your compile line and	    use the Make in the BSP dir. to compile.	    Include #define INCLUDE_SHELL in the config.h file	    To run this code invoke the function recoverExcDemo()CAVEAT    - This code fails on a mv1604 board.TESTED ON - Host/Target : Solaris 2.5.1 / mv177	    VxWorks     : 5.3.1EXAMPLE COMPILE LINE -	    make CPU=68k recoverExcSigDemo.o%make CPU=68k recoverExcSigDemo.occ68k -B/petaluma1/mayur/tor101/host/sun4-solaris2/lib/gcc-lib/ -m68040 -ansi -nostdinc -O2 -fvolatile -fno-builtin -Wall -I/h   -I. -I/petaluma1/mayur/tor101/target/config/all -I/petaluma1/mayur/tor101/target/h -I/petaluma1/mayur/tor101/target/src/config -I/petaluma1/mayur/tor101/target/src/drv -DCPU=MC68060     -c recoverExcSigDemo.cOUTPUTS/LOGFILE -On VxWorks target:==================-> ld <recoverExcSigDemo.ovalue = 688064 = 0xa7fc0-> sp (recoverExcDemo)task spawned: id = 1f90b3c, name = u0value = 33098556 = 0x1f90b3cException number 3: Task: 0x1fff3d0 (tServer)Address ErrorStatus Register     : 0x272efe2    _vxTaskEntry   +10 : _sigHandler (0, 0, 0, 0, 0, 0, 0, 0, 0, 0)27a4c6   _sigHandler    +208: _read (11, 1fff38c, 8)1d450    _read          +10 : _iosRead ([11, 1fff38c, 8, 1fff3a0, 27a4cc, 11])2460a    _iosRead       +72 : _pipeDevCreate ([1fffe98, 1fff38c, 8, 1fff370, 1d456, 11])2cd22    _pipeDevCreate +ee : _msgQReceive ([1fffea6, 1fff38c, 8, ffffffff, 0, &_taskIdSelf])78d2     _msgQReceive   +b6 : _qJobGet ([1fffeaa, ffffffff, 0, 0, 0, 1fffe98])The Output on Console:======================Starting the tServer taskRunning tServer task without causing an exceptionTask not found.Causing an address error exception in tServer taskSignal SIGBUS (bus error) received from tServer task (0x1fff3d0)TESTED ON -  Host/Target : Solaris 2.5.1 / mv2603	     VxWorks     : 5.3.1EXAMPLE COMPILE LINE - 	     make CPU=PPC603 recoverExcSigDemo.o%make CPU=PPC603 recoverExcSigDemo.occppc -B/petaluma1/mayur/tor101/host/sun4-solaris2/lib/gcc-lib/ -mstrict-align -ansi -nostdinc -O2 -fvolatile -fno-builtin -fno-for-scope  -Wall -I/h   -I. -I/petaluma1/mayur/tor101/target/config/all -I/petaluma1/mayur/tor101/target/h -I/petaluma1/mayur/tor101/target/src/config -I/petaluma1/mayur/tor101/target/src/drv -DCPU=PPC603  -DMV2600 -DTARGET_DIR="\"mv2603\""   -c recoverExcSigDemo.cOUTPUTS/LOGFILE -On VxWorks target:==================-> ld <recoverExcSigDemo.ovalue = 664232 = 0xa22a8-> sp (recoverExcDemo)task spawned: id = be7d28, name = u1value = 12483880 = 0xbe7d28Exception number 1792: Task: 0xffefa0 (tServer) "Floating point invalid operation for INF * 0""Floating point invalid operation for invalid compare"program counter:  0xffef20machine status:   0xffef00FP status & ctrl: 0x1a000016c140   vxTaskEntry    +60 : 28fae8 ([])28fba0   sigHandler     +238: read ([])13867c   read           +10 : iosRead ([])139b18   iosRead        +d0 : 13c5c0 ([])13c5e4   pipeDevCreate  +15c: msgQReceive ([])15c958   msgQReceive    +128: qJobGet ([])The Output on Console:======================Starting the tServer taskRunning tServer task without causing an exceptionShow routine of this object not configured into system.Causing an address error exception in tServer taskSignal 4 received from tServer task (0xffefa0)TESTED ON -  Host/Target : Solaris 2.5.1 / mv1603             VxWorks     : 5.3.1EXAMPLE COMPILE LINE -	     make CPU=PPC603 recoverExcSigDemo.o%make CPU=PPC603 recoverExcSigDemo.occppc -B/petaluma1/mayur/tor101/host/sun4-solaris2/lib/gcc-lib/ -mstrict-align -ansi -nostdinc -O2 -fvolatile -fno-builtin -fno-for-scope  -Wall -I/h   -I. -I/petaluma1/mayur/tor101/target/config/all -I/petaluma1/mayur/tor101/target/h -I/petaluma1/mayur/tor101/target/src/config -I/petaluma1/mayur/tor101/target/src/drv -DCPU=PPC603  -DMV1600 -DTARGET_DIR="\"mv1603\""   -c recoverExcSigDemo.cOUTPUTS/LOGFILE -On VxWorks target:==================-> ld <recoverExcSigDemo.ovalue = 664800 = 0xa24e0 = hashTblFind + 0xd0-> sp (recoverExcDemo)task spawned: id = 5cc8d8, name = u1value = 6080728 = 0x5cc8d8-> Exception number 1792: Task: 0x7fefa0 (tServer) "Floating point invalid operation for software request""Floating point invalid operation for square root""Floating point invalid operation for interger convert"program counter:  0x7fef20machine status:   0x7fef00FP status & ctrl: 0x78788825ac    vxTaskEntry    +60 : 130880 ([])130938   sigHandler     +238: read ([])5da14    read           +10 : iosRead ([])5eeb0    iosRead        +d0 : 61958 ([])6197c    pipeDevCreate  +15c: msgQReceive ([])7789c    msgQReceive    +128: qJobGet ([])The Output on Console:======================Starting the tServer taskRunning tServer task without causing an exceptionShow routine of this object not configured into system.Causing an address error exception in tServer taskSignal 4 received from tServer task (0x7fefa0)
