      1  1.1  jwise This package contains various C programming debugging utilities, such as:
      2  1.1  jwise 
      3  1.1  jwise 	addr2line - translates program addresses into file names and line
      4  1.1  jwise 	numbers. Given an address and an executable, it uses the debugging
      5  1.1  jwise 	information in the executable to figure out which file name and
      6  1.1  jwise 	line number are associated with a given address;
      7  1.1  jwise 
      8  1.1  jwise 	gcov - displays basic block profile / coverage data, if requested
      9  1.1  jwise 	via the C compiler gcc(1) command line options -fprofile-arcs and
     10  1.1  jwise 	-ftest-coverage. These options cause the compiler to insert
     11  1.1  jwise 	instrumentation into the object files it generates, which measure
     12  1.1  jwise 	how often each basic block is executed; 
     13  1.1  jwise 
     14  1.1  jwise 	gdb - is the GNU debugger. The purpose of a debugger such as GDB
     15  1.1  jwise 	is to allow you to see what is going on ``inside'' another program
     16  1.1  jwise 	while it executes, or what another program was doing at the moment
     17  1.1  jwise 	it crashed;
     18  1.1  jwise 
     19  1.1  jwise 	gprof - displays call graph profile data. gprof produces an
     20  1.1  jwise 	execution profile of C, Pascal, or Fortran77 programs.
