I am writing some assembly code and assembling them using GNU assembler. I have realized that there is no way to compile with -pg flags so that I can profile.
Is there any other way or any other assembler through which I can profile?
Thanks
Consider a profiler from google-perftools. Let's assume we've got an executable main
built from two object files: one compiled from C and one from assembly. There's no need to add any extra flags for compilation, assembling or linking.
$ LD_PRELOAD=path/to/libprofiler.so CPUPROFILE=main.prof ./main
$ pprof main main.prof --text
Using local file main.
Using local file main.prof.
Removing killpg from all stack traces.
