Currently, there are three different record types: histogram records, call-graph arc records, and basic-block execution count gprof has been ported to all the major variants of Unix. DESCRIPTION. h files, take a look and see if they are created or not. 3. Each file can contain any number of each record type. net. The reason for that myth is that gprof was not able to capture stack samples, so instead it times functions, counts their invocations, and tries to capture the call graph. "self time" tells you what fraction of the total time the program counter is found in each routine. out Using gprof requires a considerable amount of RAM which needs to be taken into account during the design. The effect of called routines is incorporated in the profile of each caller. out file, and that in turn this is generated by compiling and running my program with the "-pg" option. de Sp \" Vertical space Well, this gives a good explanation.

Essentially gprof will change the executable of your program (this is called instrumenting the code) to store some book-keeping information, e. If symspec is specified, print output only for matching symbols. out file as it is supposed to. gnu. You can also use lsstack, which is a low-tech approach but surprisingly effective, compared to gprof. it's a MingW64 distribution. Then I do: $ gprof -q . The names of the functions are then transformed, assuming the user used Verilator's --prof-cfuncs , and a report printed showing the percentage of time, etc, in each Verilog block. 1 watching.

ADRG is geographically referenced using the equal arc-second raster chart/map (ARC) system in which the globe is divided into 18 latitudinal bands, or zones. out is generated. mit. If you think autoconf is not creating config. Not quite an answer to your question, but maybe a solution to your problem: I switched from gprof to valgrind's callgrind tool, primarily because of the incredible graphical tool kcachegrind, which you can use to visualize the results. cu(41): Advisory: Loop was not unrolled, cannot deduce loop trip count avidday@cuda:~$ CUDA_PROFILE=1 .
