Hello all, Previously -a option was used to generate extra code to write profile information for basic blocks. But this options has been replaced with -fprofile-arcs. According to gprof.info " In addition to the `-pg' and `-g' options, older versions of GCC required you to specify the `-a' option when compiling in order to instrument it to perform basic-block counting. Newer versions do not require this option and will not accept it; basic-block counting is always enabled when `-pg' is on. " But compiling a code similar to the one given as a example in gprof.info and using gporf i am not getting any basic block profiling info.This is what i did a) $ gcc -g -pg 1.c After executing b) gprof -i c) gprof -l -A -x > output.gmon This is not providing any basic block profiling information. Do i need to enable some other option during compilation of the program? Or is it that gprof doesn't produce any basic block profiling information? Am i missing something? Thanks for your time. Regards, Shafi
