When using sample\-based profiles, the format of the generated file can be generated in one of three ways: .INDENT 7.0 .TP .B \-binary (default) .UNINDENT .sp Emit the profile using a binary encoding. .INDENT 7.0 .TP .B \-text .UNINDENT .sp Emit the profile in text mode. .INDENT 7.0 .TP .B \-gcc .UNINDENT .sp Emit the profile using GCC\(aqs gcov format (Not yet supported). .UNINDENT .SH SHOW .SS SYNOPSIS .sp \fBllvm\-profdata show\fP [\fIoptions\fP] [\fIfilename\fP] .SS DESCRIPTION .sp \fBllvm\-profdata show\fP takes a profile data file and displays the information about the profile counters for this file and for any of the specified function(s). .sp If \fIfilename\fP is omitted or is \fB\-\fP, then \fBllvm\-profdata show\fP reads its input from standard input. .SS OPTIONS .INDENT 0.0 .TP .B \-all\-functions Print details for every function. .UNINDENT .INDENT 0.0 .TP .B \-counts Print the counter values for the displayed functions. .UNINDENT .INDENT 0.0 .TP .B \-function=string Print details for a function if the function\(aqs name contains the given string. .UNINDENT .INDENT 0.0 .TP .B \-help Print a summary of command line options. .UNINDENT .INDENT 0.0 .TP .B \-output=output, \-o=output Specify the output file name. If \fIoutput\fP is \fB\-\fP or it isn\(aqt specified, then the output is sent to standard output. .UNINDENT .INDENT 0.0 .TP .B \-instr (default) Specify that the input profile is an instrumentation\-based profile. .UNINDENT .INDENT 0.0 .TP .B \-sample Specify that the input profile is a sample\-based profile. .UNINDENT .SH EXIT STATUS .sp \fBllvm\-profdata\fP returns 1 if the command is omitted or is invalid, if it cannot read input files, or if there is a mismatch between their data. .SH AUTHOR Maintained by The LLVM Team (http://llvm.org/). .SH COPYRIGHT 2003-2016, LLVM Project .\" Generated by docutils manpage writer. .
