Hi Stephane,

I observed one strange thing. I can build libpfm to support Montecito
only and not generic IA64 and Itanium I&II. But I can not do this with
pfmon. I can change config.mk accordingly but linking fails with
unresolved symbols:

gcc -o pfmon pfmon.o pfmon_smpl.o pfmon_util.o pfmon_system.o
pfmon_task.o pfmon_symbols.o pfmon_results.o pfmon_hash.o
pfmon_smpl_dfl.o pfmon_os.o pfmon_util_ia64.o pfmon_montecito.o -O2 -g
-Wall -Werror -D_REENTRANT -I/usr/local/include -DCONFIG_PFMON_IA64
-DPFMON_DEBUG -DDATADIR=\"/usr/local/share/pfmon\" -I.
-I/usr/include/libelf -DCONFIG_PFMON_DEMANGLE -D_GNU_SOURCE
-DCONFIG_PFMON_IA64 -DPFMON_DEBUG -g -DCONFIG_PFMON_MONTECITO -static
smpl_mod/libsmplfmt.a  -L/usr/local/lib -lpfm  -L/usr/lib -liberty
-lpthread -lelf -lm -lrt -ldl
smpl_mod/libsmplfmt.a(dear_itanium.o): In function `dear_ita_info':
/root/pfmon/pfmon/smpl_mod/dear_itanium.c:32: undefined reference to
`pfm_ita_is_dear'
/root/pfmon/pfmon/smpl_mod/dear_itanium.c:33: undefined reference to
`pfm_ita_is_dear_tlb'
smpl_mod/libsmplfmt.a(dear_itanium2.o): In function `dear_ita2_info':
/root/pfmon/pfmon/smpl_mod/dear_itanium2.c:34: undefined reference to
`pfm_ita2_is_dear'
/root/pfmon/pfmon/smpl_mod/dear_itanium2.c:35: undefined reference to
`pfm_ita2_is_dear_alat'
/root/pfmon/pfmon/smpl_mod/dear_itanium2.c:35: undefined reference to
`pfm_ita2_is_dear_tlb'

Would it be possible to get rid of this stuff and create a version of
pfmon that is only aware of Montecito?


Regards, Michael
