Thanks Paolo. For now on I have only access to an ubuntu machine. I will try with Shark back home.
With kcachegrind at a first glance I got a total of self cost ~2 for comp.c, gst-parse.c, lex.c ~26 for interp.c, interp_bc.inl, Not sure what is the unit but a time unit for sure. I also have many other file but it is not sure whether to include them in the compiler or the interpreter. (alloc.c, callin.c, dict.c(~4 time unit), input.c(~3 time unit), oop.c(~20 time unit), prims.def (~18 time unit)...) I also got some <cycle 3> which take ~28 time unit. I don't know to what it correspond. ----- Message d'origine ---- De : Paolo Bonzini <[email protected]> À : Mathieu Suen <[email protected]> Cc : [email protected] Envoyé le : Jeu 3 juin 2010, 14h 12min 57s Objet : Re: [Help-smalltalk] µTrying to compile gst for profiling On 06/03/2010 10:54 AM, Mathieu Suen wrote: > Hi, > > > I try to build a gst with profiling information. > So I configure gst with: > > ./configure CFLAGS=-pg > > and make give me thix error: > > gcc: -pg and -fomit-frame-pointer are incompatible > > > I guess I should remove the oprion -fomit-frame-pointer but > I don't know the right way of doing it. > Is there a way to compile gst with profiling information? Try this: diff --git a/configure.ac b/configure.ac index b9f4b43..fc2ce06 100644 --- a/configure.ac +++ b/configure.ac @@ -264,8 +264,9 @@ AC_MSG_ERROR([GNU Smalltalk requires GCC 3.3 or later.]) ;; esac -case $host_cpu in - i*86) LIBGST_CFLAGS='-fomit-frame-pointer' ;; +case '$host_cpu: $CFLAGS ' in + i*86:*' -pg '*) ;; + i*86:*) LIBGST_CFLAGS='-fomit-frame-pointer' ;; *) ;; esac AC_SUBST(LIBGST_CFLAGS) If you're on the Mac, however, I would use Shark. Much simpler and much more powerful. Paolo _______________________________________________ help-smalltalk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-smalltalk
