HOWTO: Basic-block profiling on -current.
I have committed the bits needed to use GCC's basicblock profiling on -current. Make sure to recompile the kernbb(8) program first. Here's an simple example how to profile a single file (vfs_bio.c): cd /sys/i386/conf config YOURKERNEL cd ../compile/YOURKERNEL make depend make all rm vfs_bio.o make vfs_bio.o DEBUG=--test-coverage --profile-arcs make all make install reboot # run your test. kernbb cd /sys/i386/compile/YOURKERNEL gcov vfs_bio.c # examine vfs_bio.c.gcov If you want to profile multiple files, you just give them all the same treatment as vfs_bio. It's perfectly possible to profile the entire kernel if you want to. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.

Hello. This is just cool! I was wondering, did you receive my mail on this issue? It seems that I sent mail to you before too, but never got a reply. Thanks. - Hiten On Mon, Jan 06, 2003 at 02:28:52PM +0100, Poul-Henning Kamp wrote the words in effect of: I have committed the bits needed to use GCC's basicblock profiling on -current.
