NAME

       llvm-prof - print execution profile of LLVM program

SYNOPSIS

       llvm-prof [options] [bitcode file] [llvmprof.out]

DESCRIPTION

       The llvm-prof tool reads in an llvmprof.out file (which can optionally use a specific file
       with the third program argument), a bitcode 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.

OPTIONS

       --annotated-llvm or -A
           In addition to the normal report printed, print out the code for the program,
           annotated with execution frequency information. This can be particularly useful when
           trying to visualize how frequently basic blocks are executed.  This is most useful
           with basic block profiling information or better.

       --print-all-code
           Using this option enables the --annotated-llvm option, but it prints the entire
           module, instead of just the most commonly executed functions.

       --time-passes
           Record the amount of time needed for each pass and print it to standard error.

EXIT STATUS

       llvm-prof returns 1 if it cannot load the bitcode file or the profile information.
       Otherwise, it exits with zero.
