Re: [Vm-dev] Profiling with gprof

Hi,

has anyone successfully profiled the VM with gprof lately, preferably on Linux? If so, how did you do it?

I've tried the hints at http://wiki.squeak.org/squeak/2041 but I guess they're badly out of date: configure and GCC 4.2 will choke on '-g -pg -a' but not '-g -pg', and so there's no bb.out.

I just hand-edit ./Makefile and ./vm/Makefile in the build directory, and add "pg" to the CFLAGS definition of each. The resulting VM produces a gmon.out file, and running "gprof ./squeak" provides the profiling output. This is on Linux, and I just went by the information in the gprof(1) man page.
