NAME

6       llvm-prof - print execution profile of LLVM program
7

SYNOPSIS

9       llvm-prof [options] [bitcode file] [llvmprof.out]
10

DESCRIPTION

12       The llvm-prof tool reads in an llvmprof.out file (which can optionally
13       use a specific file with the third program argument), a bitcode file
14       for the program, and produces a human readable report, suitable for
15       determining where the program hotspots are.
16
17       This program is often used in conjunction with the utils/profile.pl
18       script.  This script automatically instruments a program, runs it with
19       the JIT, then runs llvm-prof to format a report.  To get more
20       information about utils/profile.pl, execute it with the -help option.
21

OPTIONS

23       --annotated-llvm or -A
24           In addition to the normal report printed, print out the code for
25           the program, annotated with execution frequency information. This
26           can be particularly useful when trying to visualize how frequently
27           basic blocks are executed.  This is most useful with basic block
28           profiling information or better.
29
30       --print-all-code
31           Using this option enables the --annotated-llvm option, but it
32           prints the entire module, instead of just the most commonly
33           executed functions.
34
35       --time-passes
36           Record the amount of time needed for each pass and print it to
37           standard error.
38

EXIT STATUS

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