- Authentication-results: sourceware.org; auth=none
This set of patches adds support for examining kernel-backed user threads on
FreeBSD. There is more history in a comment in fbsd-nat.c, but this target
uses ptrace directly (instead of libthread_db) to support the current
threading library (libthr) on FreeBSD which uses a kernel thread for each
user thread. Support for thread names in both core dumps (via FreeBSD's
OS-specific NT_THRMISC core note) and live is supported as is scheduler
locking. gcore generates register notes for each thread as well.
The first two patches are to binutils to support FreeBSD-specific core
notes. The last four are to GDB.
This includes changes to address feedback from the previous version of
John Baldwin (6):
Add support to readelf for reading FreeBSD ELF core notes.
Add a psuedosection for the NT_FREEBSD_THRMISC note.
Display per-thread information for threads in FreeBSD cores.
Use LWP IDs with ptrace register requests on FreeBSD.
Add support for LWP-based threads on FreeBSD.
Dump register notes for each thread when generating a FreeBSD core.
