1This package contains the man pages groff source on various C programming 2debugging utilities, such as: 3 4 addr2line - translates program addresses into file names and line 5 numbers. Given an address and an executable, it uses the debugging 6 information in the executable to figure out which file name and 7 line number are associated with a given address; 8 9 gcov - displays basic block profile / coverage data, if requested 10 via the C compiler gcc(1) command line options -fprofile-arcs and 11 -ftest-coverage. These options cause the compiler to insert 12 instrumentation into the object files it generates, which measure 13 how often each basic block is executed; 14 15 gdb - is the GNU debugger. The purpose of a debugger such as GDB 16 is to allow you to see what is going on ``inside'' another program 17 while it executes, or what another program was doing at the moment 18 it crashed; 19 20 gprof - displays call graph profile data. gprof produces an 21 execution profile of C, Pascal, or Fortran77 programs. 22
