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.
