Subject: [Qemu-devel] [ARM] add with PC in argument
Date: Sun, 24 Feb 2008 13:57:04 +0100 [thread overview]
Message-ID: <47C169A0.1020705@wanadoo.fr> (raw)
Hello,
I got a problem in an IRQ handler of mutek OS
(https://www-asim.lip6.fr/trac/mutekh), target ARM Integrator/CM
922T-XA10. I try to port it on Qemu. A porting has been done for Skyeyes
So in qemu I don't get the same comportement. The add of lr = pc + 4
gives lr = pc + 8 into qemu.
I think that s->pc += 4 at start of disas_arm_insn alters the result.
Could you confirm ?
0x7c add lr, pc, #4
0x80 ldr pc, =SystemInterrupt
0x84 ldr r3, [sp, #PSR_OFF] <= never executed in Qemu
0x88 msr spsr_cxsf, r3 @ put cpsr in SPSR
0x8c ldmia sp, {r0-r15}^ @ restore Context
B.R.
Claude
