Hello, I've implemented profiler for SuperH architecture. It has been tested with GCC changes. I've put _mcount.S under sysdeps/unix/sysv/linux/sh/, but it might be upper directory. Besides, there's small fix for linuxthreads for SuperH. ChangeLog 2001-12-12 NIIBE Yutaka <gniibe@m17n.org> * sysdeps/unix/sysv/linux/sh/Makefile (sysdep_routines): Add _mcount. * sysdeps/unix/sysv/linux/sh/_mcount.S: New file. * sysdeps/sh/sysdep.h (CALL_MCOUNT): Implemented. * sysdeps/sh/machine-gmon.h: Remove "NOTYET" comment, as we are ready. linuxthreads/ChangeLog 2001-12-12 NIIBE Yutaka <gniibe@.m17n.org> * sysdeps/sh/pt-machine.h (INIT_THREAD_SELF): Added __volatile__ qualifier to be safe. --- linuxthreads/sysdeps/sh/pt-machine.h 2001/07/26 01:32:01 1.5 +++ linuxthreads/sysdeps/sh/pt-machine.h 2001/12/12 08:45:08 @@ -53,4 +53,4 @@ struct _pthread_descr_struct; /* Initialize the thread-unique value. */ #define INIT_THREAD_SELF(descr, nr) \ - ({ __asm__("ldc %0,gbr" : : "r" (descr));}) + ({ __asm__ __volatile__("ldc %0,gbr" : : "r" (descr));}) --- sysdeps/sh/machine-gmon.h 2001/07/06 04:56:03 1.2 +++ sysdeps/sh/machine-gmon.h 2001/12/12 08:45:09 @@ -17,8 +17,6 @@ Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA. */ -/* NOTYET */ - /* We must not pollute the global namespace. */ #define mcount_internal __mcount_internal --- sysdeps/sh/sysdep.h 2001/07/06 04:56:03 1.2 +++ sysdeps/sh/sysdep.h 2001/12/12 08:45:09 @@ -60,7 +60,15 @@ /* If compiled for profiling, call `mcount' at the start of each function. */ #ifdef PROF -#define CALL_MCOUNT /* NOTYET */ +#define CALL_MCOUNT \ + mov.l 1f,r1; \ + sts.l pr,@-r15; \ + mova 2f,r0; \ + jmp @r1; \ + lds r0,pr; \ + .align 2; \ +1: .long mcount; \ +2: lds.l @r15+,pr #else #define CALL_MCOUNT /* Do nothing. */ #endif --- sysdeps/unix/sysv/linux/sh/Makefile 2001/09/25 01:30:37 1.2 +++ sysdeps/unix/sysv/linux/sh/Makefile 2001/12/12 08:45:10 @@ -1,3 +1,7 @@ +ifeq ($(subdir),gmon) +sysdep_routines += _mcount +endif + ifeq ($(subdir),io) sysdep_routines += pipe endif --- sysdeps/unix/sysv/linux/sh/_mcount.S Tue Dec 4 19:42:15 2001 +++ sysdeps/unix/sysv/linux/sh/_mcount.S Wed Dec 12 17:44:52 2001 @@ -0,0 +1,67 @@ +/* Machine-specific calling sequence for `mcount' profiling function.
