Hi, thanks for your response. No, it isnt a
glibc/libthread_db version problem ... I've built the
same sources for ia32 and the test passes fine. It on
powerpc that I see the failure.
So, after a little digging, it seems like the load
module address that gdb is using to make the call to
td_thr_tls_get_addr_p is bogus. At the moment, I am
comparing results with gdb-6.3 which works in my
envrionment. The offset to the variable within LM
looks fine. Still debugging. I am not too sure of what
the concept of the load module address is. Where would
be the appropriate place to look for background info?
glibc TLS documentation?
The lm_addr calculated in dwarf2loc.c looks bad on
ppc.
