GNU Info (gprof.info)IncompatibilitiesIncompatibilities with Unix `gprof' *********************************** GNU `gprof' and Berkeley Unix `gprof' use the same data file `gmon.out', and provide essentially the same information. But there are a few differences. * GNU `gprof' uses a new, generalized file format with support for basic-block execution counts and non-realtime histograms. A magic cookie and version number allows `gprof' to easily identify new style files. Old BSD-style files can still be read. Note: File Format. * For a recursive function, Unix `gprof' lists the function as a parent and as a child, with a `calls' field that lists the number of recursive calls. GNU `gprof' omits these lines and puts the number of recursive calls in the primary line. * When a function is suppressed from the call graph with `-e', GNU `gprof' still lists it as a subroutine of functions that call it. * GNU `gprof' accepts the `-k' with its argument in the form `from/to', instead of `from to'. * In the annotated source listing, if there are multiple basic blocks on the same line, GNU `gprof' prints all of their counts, separated by commas. * The blurbs, field widths, and output formats are different. GNU `gprof' prints blurbs after the tables, so that you can see the tables without skipping the blurbs. automatically generated by info2www version 1.2.2.9 |
