Greetings
Just been debugging some exception handling stuff and I'm sure that the
combination of bdi2000, gdb & ddd I have is suffering an 'off by one'
error in the register display
e.g. I see this
srr0 0x818000
srr1 0x3fca360
tbl 0x9002
But the sensible values of srr0 & srr1 should be
srr0 0x3fca360
srr1 0x9002
so that fault address is in srr0 and the bits from MSR (EE, ME and RI)
are set in srr1.
Anyone seen this and where is the slippage coming from (r0 to r31 look
OK as far as I can see but don't really know about the others!!).
I've tried both REGLIST ALL and REGLIST SPR in the bdi2000 config but it
doesn't appear to make a difference.
bdi2000 code=1.13, fpga=1.02
mpc8xx target
gdb 5.3
ddd 3.3.1
Many thanks
