Mark Johnston	a7e13d50fe	librtld_db: Use the auxv to figure out where to look up loader symbols. ... Previously, librtld_db just hardcoded /libexec/ld-elf.so, which isn't correct for processes that aren't using the native ABI. With this change, librtld_db can be used to inspect non-native processes; in particular, dtrace -c now works for 32-bit executables on amd64. MFC after: 1 month	2016-07-30 03:05:23 +00:00
Mark Johnston	b252f278ea	Handle the different event types properly in rd_event_addr(). In particular, ... with r265456 _r_debug_postinit can be used for RD_POSTINIT events. rtld(1) uses r_debug_state for dl state transitions, so we use its address for RD_DLACTIVITY events.

Rui Paulo	cb31498865	Import the librtld_db library. This is needed by userland DTrace. ... This is not yet enabled in the build because I also need to import a new version of libproc. Sponsored by: The FreeBSD Foundation	2010-07-31 14:26:10 +00:00
