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 these patches. 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. bfd/ChangeLog | 4 + bfd/elf.c | 7 + binutils/ChangeLog | 5 + binutils/readelf.c | 35 +++++ gdb/ChangeLog | 71 +++++++++ gdb/NEWS | 6 + gdb/amd64bsd-nat.c | 24 +-- gdb/config.in | 3 + gdb/configure | 16 ++ gdb/configure.ac | 7 + gdb/doc/ChangeLog | 4 + gdb/doc/gdb.texinfo | 5 + gdb/fbsd-nat.c | 423 +++++++++++++++++++++++++++++++++++++++++++++++---- gdb/fbsd-tdep.c | 191 +++++++++++++++++++---- gdb/i386bsd-nat.c | 30 ++-- gdb/inf-ptrace.c | 2 +- gdb/inf-ptrace.h | 5 + gdb/ppcfbsd-nat.c | 12 +- include/ChangeLog | 13 ++ include/elf/common.h | 14 ++ 20 files changed, 785 insertions(+), 92 deletions(-) -- 2.7.0
