44 utility can produce both C sources or assembly sources of a program with
45 a line-by-line based profiling.
46 The profiling information is retrieved through a
48 raw output while the program operations are retrieved through the
54 the raw output is passed through the
56 argument, while the program is passed through the
66 to work, it will fail if one of them is not available.
68 The following options are available:
69 .Bl -tag -width indent
71 Shows the program profiling inlined in the assembly code only.
72 No C information involving C sources is provided.
74 Prints out information about the usage of the tool.
76 Changes the lower bound (expressed in percentage) for traced functions
77 that will be printed out in the report.
78 The default value is 0.5%.

82 This directory specifies where
84 should look for the kernel and its modules.
93 utility to retrieve the C code, the program needs to be compiled with
95 Sometimes, in particular with heavy optimization levels, the
97 utility embeds the code of inlining functions directly in the callers,
98 making an output difficult to read.
