feedback(1) General Commands Manual feedback(1)NAME
feedback - Generate an optimization feedback file using pixie and prof
SYNOPSIS
feedback [prof-options] [-o feedback-file] [-v] objfile [objfile-arguments]
OPTIONS
The feedback command accepts the following prof(1) options and any unambiguous abbreviations: -asm, -clock megahertz, -{e|E}xclude proce-
dure_name, -feedback filename, -heavy, -invocations, -lines, -merge filename, -numbers, -{o|O}nly procedure_name, -procedures, -quit n,
-testcoverage, -truecycles [0,1,2], -zero.
The feedback command ignores all other options in order to provide compatiblility with older versions of the feedback command. An
option argument following an option not recognized by this or older versions of the feedback command will be treated as the objfile
argument. Specifies the name of the feedback file. This can also be specified by the -feedback option of prof. You should use only
one of these options to specify a feedback file, not both. Causes the pixie, application, and prof commands to be printed as they
are invoked.
OPERANDS
Specifies the executable of the application for which a feedback file is to be generated. A pixie-instrumented version of this executable
will be executed with the current working directory and environment variables. The feedback file that is generated will reflect the behav-
ior of one execution of the instrumented objfile. Specify the arguments that will cause the behavior that you want to have optimized when
the compiler uses the feedback file.
DESCRIPTION
The feedback command invokes pixie to add profiling code to an object file. The object file generated by pixie is executed to obtain pro-
filing information. The feedback command then invokes prof to analyze the profiling information.
If the output of objfile needs to be redirected, but not the output of the feedback utility, the redirection characters need to have sh(1)
syntax and be within quotes. If objfile is multi-threaded, the LD_LIBRARY_PATH environment variable needs to include the current working
directory.
EXAMPLES
Send the profiling information to the standard output: $ feedback myprog Write a binary formatted performance profile to the file
myprog.feedback, which then helps a subsequent recompilation optimize the program: $ feedback -feedback myprog.feedback myprog $ cc -O
-feedback myprog.feedback -o myprog myprog.c
FILES
Object with profiling code. Generated by pixie. Basic block addresses. Generated by pixie. Basic block counts. Generated by
myprog.pixie.
Note: Run pixie and prof independently if alternative names are needed.
