Hi,
i use insight 6.4 built for target v850-unknown-elf.
My host is a x86 linux PC.
While debugging a program in the simulator i found that
at one point in the program flow the simulator never
returns.
This is reproducible. In the program flow the PC is 0x0C66.
When i hit "Step Asm Inst (S)" i never get the chance again
to get control over "insight".
0xc62 <_malloc_r+104>: jmp [lp]
0xc64 <_malloc_r+106>: mov r25, r6
0xc66 <_malloc_r+108>: jarl 0x11f4 <__malloc_lock>, lp
0xc6a <_malloc_r+112>: movea 503, r0, r10
0xc6e <_malloc_r+116>: cmp r10, r28
000011f4 <___malloc_lock>:
11f4: 7f 00 jmp [lp]
To my understanding this should never happen, right?
Is there anything i could have done wrong?
I can provide every further information you need, Sources, Setup,
ELF file, ...
I have set up insight for target V850, the tool chain produces code
for V850E (E at the end), but i got a hint (from either this list
or the "insight"-list) to use the target V850.
Can anybody give me a hint on this one?
Best regards,
Torsten.
