36 \fBllvm\-profdata\fP \fIcommand\fP [\fIargs...\fP]
39 The \fBllvm\-profdata\fP tool is a small utility for working with profile
51 \fBllvm\-profdata merge\fP [\fIoptions\fP] [\fIfilenames...\fP]
54 \fBllvm\-profdata merge\fP takes several profile data files
55 generated by PGO instrumentation and merges them together into a single
56 indexed profile data file.
61 Print a summary of command line options.
65 .B \-output=output, \-o=output
66 Specify the output file name. \fIOutput\fP cannot be \fB\-\fP as the resulting
67 indexed profile data can\(aqt be written to standard output.
72 \fBllvm\-profdata show\fP [\fIoptions\fP] [\fIfilename\fP]
75 \fBllvm\-profdata show\fP takes a profile data file and displays the
76 information about the profile counters for this file and
77 for any of the specified function(s).
79 If \fIfilename\fP is omitted or is \fB\-\fP, then \fBllvm\-profdata show\fP reads its
80 input from standard input.
85 Print details for every function.
90 Print the counter values for the displayed functions.
95 Print details for a function if the function\(aqs name contains the given string.
100 Print a summary of command line options.
104 .B \-output=output, \-o=output
105 Specify the output file name. If \fIoutput\fP is \fB\-\fP or it isn\(aqt specified,
106 then the output is sent to standard output.
110 \fBllvm\-profdata\fP returns 1 if the command is omitted or is invalid,
111 if it cannot read input files, or if there is a mismatch between their data.
