PCB convergence, part the first:

Move the pointer to the current user trapframe from struct mdproc to struct
pcb (as on arm26). Only tested by compiling kernels on arm32 and
hpcarm (dnard seems to be incomplete anyway). Someone should try running one.

Stop using #ifdef arm32, since future NetBSD/arm ports are likely

not to provide it.
For things which are historical oddities of NetBSD/arm26, use #ifndef arm26.
For things which are inherently dependent on the size of program space in use,
use #ifdef PROG32 (and include opt_progmode.h).

Move arm32 ports over to using <arm/armreg.h>, so <cpu.h> mostly contains

Unify arm26 and arm32 trapframe structures. The unified trapframe is the same

Storing four-byte pointers to two-character strings is silly. All the
...
auxilliary tables used by the disassembler are now char[][].
The main table still uses pointers because:
- the longest instruction name, "imbrange" is >7 characters long, which would
make the field length wasteful.
- GCC spots that most of the formats are shared and makes them pointers to the
same string, so turning them into char[8] would be counter-productive.

Move all the nasty big tables into the text segment. This isn't much use in

Correct spelling of SWP.
2001-01-12 22:19:15 +00:00
e9bb2a7916
Correct immediate constant handling: bits [11:8] are a rotation, not a shift.
...
Also add support for the "P" modifier to TEQ, TST, CMP and CMN, and don't
bother displaying the "S" bit for these instructions.
Together, these correct the disassembly of 0xe33ff3c2 (an instruction in
arm26 irq_handler() from "teqs r15, #0x08000000" to "teqp r15, 0x08000003".
