How to compile demo.c example:
Compiling for full-tracing can be done with:
. run source_file
If you want to trace specific function, use:
. run source_file function_name
To run program that will generate output file (out.txt) use:
./main
Tracing output is located at:
out.txt
Analyzing data:
First of all, you need to compile evaluate.c using:
gcc -o evaluate evaluate.c
To analyze output file you can use following command:
./evaluate out.txt
This will print runtime of each function onto stdout.
The first parameter is the output file you want to analyze.
Printing histogram for specific function
Requires gnuplot.
To print a hostigram into a PNG file you first need to compile ev_graph.c file using:
gcc -o graph ev_graph.c
Usage:
. data2graph tracing_output text_output image_output
Example:
. data2graph out.txt temp.txt out.png
tracing_output is the output file from ./main
text_output is any file where temporary data will be stored
image_output has to be png (!) file, will be generated using temporary data
