commit 18da588786c9d0e98f7cd79fbc5550cecee853e0
Author: Mark Wielaard <mjw@redhat.com>
Date: Fri Jul 9 18:02:33 2010 +0200
PR10080 Add vdso tracking (x86).
The translator will now pick up all the possible vdso.so files (luckily
they are small). At runtime when the task finder notifies us of a new
process we will check against the build id an add the vdso to the vma map.
* translate.cxx (find_vdso): New function.
(add_unwindsym_vdso): Likewise.
(emit_symbol_data): If vma tracker enabled call add_unwindsym_vdso.
* buildrun.cxx (compile_pass): Check STAPCONF_MM_CONTEXT_VDSO.
* runtime/autoconf-mm-context-vdso.c: New test.
* runtime/vma.c (_stp_vma_match_vdso): New function.
(_stp_vma_exec_cb): Call _stp_vma_match_vdso when register_p && process_p.

Remove symtab boolean field from session. staprun symtab loading is gone.
