11.1SjwiseThis package contains various C programming debugging utilities, such as: 21.1Sjwise 31.1Sjwise addr2line - translates program addresses into file names and line 41.1Sjwise numbers. Given an address and an executable, it uses the debugging 51.1Sjwise information in the executable to figure out which file name and 61.1Sjwise line number are associated with a given address; 71.1Sjwise 81.1Sjwise gcov - displays basic block profile / coverage data, if requested 91.1Sjwise via the C compiler gcc(1) command line options -fprofile-arcs and 101.1Sjwise -ftest-coverage. These options cause the compiler to insert 111.1Sjwise instrumentation into the object files it generates, which measure 121.1Sjwise how often each basic block is executed; 131.1Sjwise 141.1Sjwise gdb - is the GNU debugger. The purpose of a debugger such as GDB 151.1Sjwise is to allow you to see what is going on ``inside'' another program 161.1Sjwise while it executes, or what another program was doing at the moment 171.1Sjwise it crashed; 181.1Sjwise 191.1Sjwise gprof - displays call graph profile data. gprof produces an 201.1Sjwise execution profile of C, Pascal, or Fortran77 programs. 21
