* Move definitions of exact-width integer types from <machine/types.h>
...
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
intmax_t, pointer-type and size_t arguments.

Rather large overhaul. Mostly cosmetic, but also:

Sprinkle pmap_update() calls after calls to:
...
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()

These calls are relatively conservative. It may be possible to
optimize these a little more.

Remove pmap_kenter_pgs(). It was never really adopted by

Change the value of tf_pc in undefined-instruction handlers on arm32. It now

2001-03-13 20:22:02 +00:00
ce5529eabf
Change undefined instruction handler to use a linked list for each

co-processor. This is necessary so we can have several handlers for
CP0 (used as a catch-all for non-CP instructions).
Handlers are now removed using remove_coproc_handler(), rather than by calling
install_coproc_handler() with a NULL handler.
Because install_coproc_handler() can now allocate memory, there's a version
for use at boot time that doesn't.

Common <arm/reg.h> (and hence common struct reg) for ARM.
...
This is theoretically backward-incompatible on arm26, but GDB doesn't work there
yet anyway.
2001-02-11 14:51:55 +00:00
1178bf4219
Initial potentially sharable <arm/armreg.h>. Used by all arm26 code.
2001-01-22 22:10:39 +00:00
8805bd8b56
Unify arm26 and arm32 trapframe structures. The unified trapframe is the same
...
shape as the old arm32 one, but there are a few #defines to keep arm26 code
happy. Anything that depends on the precise shape of the trapframe,
and especially on being able to treat it as an array of registers, has been
updated.

Add <arm/frame.h>, for shared stack frame structures. Currently, only sigframes
...
are common.
2001-01-18 21:48:25 +00:00
6b017eaa04
Add ARMv5 instructions: BLX, CLZ, BKPT, MCR2, MRC2, CDP2, LDC2, STC2.
...
Also correct a comment.

A bit of extra discussion based on the latest ARM ARM.

Move <machine/signal.h> into shared directory.

Make db_disasm_interface const.
2001-01-13 16:53:27 +00:00
f52101bc64
Make all the disasm_interface_t arguments const, thus allowing us to
...
allocate them statically in the text segment. Do so for disassemble().
2001-01-13 16:52:01 +00:00

ANSIfy, un-__Pify, and in the case of disassem.c, add an RCSID.
2001-01-13 16:44:25 +00:00
78c0ba909e
Separate out sigcode into its own file, since it's shared by arm26 and arm32.

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
...
the kernel at present, but maybe one day when we have a ROMmable kernel...
2001-01-12 22:44:08 +00:00
cdae07e857
Correct comments (the code does support LDF, STF, LDC, STC).
...
Support BX (for completeness).
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".

Move db_disasm.c into sys/arch/arm/arm. Use arm26 version, since it should
...
generate smaller compiled code.
2001-01-12 21:31:51 +00:00

Move the generic ARM disassembler from arm32/arm32 to arm/arm.
2001-01-12 13:43:11 +00:00
6fa98146d5
Start merging actual code in arm32 and arm26:
...
arm32/arm32/in_cksum_arm32.c -> arm/arm/in_cksum_arm.c
Also move specification of other checksum stuff to files.arm, even though we
use the MI code for that.
2001-01-11 23:27:26 +00:00

Share <machine/elf_machdep.h> between arm26 and arm32.

Install all the headers (arm32 does).
2001-01-11 21:05:03 +00:00

Remove <arm/endian_machdep.h>, since we might get a big-endian ARM port

some time.

Header files which don't differ between arm32 and arm26 and can thus be

shared.
