Fix and harmonize some of the code dealing with address offsets encoded in

instructions. ok drahn@, gkoehler@

Decode the %{ds}(%{A}) operand of ld, std instructions.

2020-05-22T00:33:45Z

I don't expect to see these 64-bit instructions in 32-bit kernels, but I'm going to copy this code to powerpc64. ok drahn@

Use '/t' on all architectures to get a trace via TID.

Sync existing stacktrace_save() implementations

2020-04-18T04:45:20Z

Upgrade stacktrace_save() to stacktrace_save_at() on architectures where the latter is missing. Define stacktrace_save() as an inline function in header to reduce duplication of code. OK mpi@

Implement stacktrace_save_at() required for upcoming WITNESS.

db_addr_t -> vaddr_t

Substitute boolean_t/TRUE/FALSE by int/1/0.

Use the debugger mutex for `ddb_mp_mutex'. This should prevent a race

2019-03-23T05:47:22Z

that could leave `ddb_mp_mutex' locked if one CPU incremented `db_active' while another CPU was in the critical section. When the race hit, the debugger was unable to resume execution or switch between CPUs. Race analyzed by patrick@ OK mpi@ patrick@

Do not panic from ddb(4) when a lock requirement isn't fulfilled.

2018-03-20T15:45:32Z

Extend the logic already present for panic() to any DDB-related operation such that if ddb(4) is entered because of a fault or other trap it is still possible to call 'boot reboot'. While here stop printing splassert() messages as well, to not fill the buffer. ok visa@, deraadt@

add support for printing function arguments when displaying a trace

2017-10-18T16:59:18Z

from DDB. this uses CTF to get the correct number of arguments. ok mpi@
