[bug] Synchonization of registers window in h8300 Insight

[bug] Synchonization of registers window in h8300 Insight

[Andrew Volkov]

Hi,

I found next incorrectness, when run insight fo h8300 target:

If I run gdb without any parameters, and make view registers, then 
Insight show registers window for default platform (h8300 16bits registers),

then when I load my program, wich build for h8300h or h8300s (32bits
registers) 
target, registers window STILL remain for h8300 target, i.e. not updated for
new target.

Regards
Andrey Volkov

This could be an architecture change bug. It may not even be implemented
in the version of Insight you are using. What does "gdb -v" (or "show
version") give?

Just FYI, the h8300 target doesn't use GDB's multi-arch framework to 
flip between architectures.  I suspect that is the problem.

Ok, I'm ready to start converting h8300 part of GDB to multi-arch.

Unfortunatly the architecture is known.  GDB makes use of that default 
architecture when talking to some targets.

The best way to fix this really is multi-arch - all sorts of problems 
just mysteriously disappear!  Would you (FSF assignment permitting) be 
interested in helping with converting the h8300 to multi-arch?

Indeed, I didn't touch the H8300 when I multiarched the sh.

I attach bzipped hello.out and hello.c (COFF with full gdb debug info).

Now, whats I do:

$h8300-hms-gdb
<Ctrl-R> (show regs. window)
Ok, Insight show me regs for h8300 (16 bits regs: r0...r6, sp, ccr ...)

Here started snapshot from console window ->
------------------------------------------------------
(gdb) show architecture 
The target architecture is set automatically (currently unknown)

(gdb) file hello.out
(gdb) ta si
Connected to the simulator.

(gdb) lo
Loading section .text, size 0xfc vma 0x100
Loading section .data, size 0x298 vma 0x1fc
Loading section .stack, size 0x4 vma 0x3fffc
Start address 0x102
Transfer rate: 7360 bits in <1 sec.

(gdb) show architecture 
The target architecture is set automatically (currently h8300s)

(gdb) set architecture h8300s
The target architecture is assumed to be h8300s

(gdb) show architecture 
The target architecture is assumed to be h8300s

(gdb) 
------------------------------------------------------

But Registers widow still show h8300 registers :((,
but must show: er0...er6, sp, ccr ...

It's not so good idea, because h8300 and h8300s have different number 
of hardware regs (it not implemented in current, but may will implement 
in future ver. of gdb), and if I forget close Regs. windows before 
changing architecture (through load or somehow else), then Insight 
(not gdb) will die when I will try close this window :(.

Another warkaround, NETHER run gdb without args (ex. $h8300-hms-gdb
hello.out).

But, I think better way remain registers window blank (if it possible), or 
invisible while architecture is unknown.

Unfortunatly the architecture is known.  GDB makes use of that default 
architecture when talking to some targets.

The best way to fix this really is multi-arch - all sorts of problems 
just mysteriously disappear!  Would you (FSF assignment permitting) be 
interested in helping with converting the h8300 to multi-arch?
