llvm-prof - print execution profile of LLVM program
llvm-prof [options] [bytecode file] [llvmprof.out]
The llvm-prof tool reads in an llvmprof.out file (which can optionally use a specific file with the third program argument), a bytecode file for the program, and produces a human readable report, suitable for determining where the program hotspots are.
This program is often used in conjunction with the utils/profile.pl script. This script automatically instruments a program, runs it with the JIT, then runs llvm-prof to format a report. To get more information about utils/profile.pl, execute it with the --help option.
llvm-prof|llvm-prof returns 1 if it cannot load the bytecode file or the profile information. Otherwise, it exits with zero.
llvm-prof is maintained by the LLVM Team (http://llvm.cs.uiuc.edu).
