Re: [Qemu-devel] big endian arm.

Hi Frederic,

I'm slowly working on Hercules MCU peripherals and use a R4F core.

So far no problem here

Maybe I didn't hit this problem since I use the same setup than with 
openocd/real cpu with the following .gdbinit:

    set architecture armv5te
    set arm fpu vfp
    set endian big
    set remote hardware-breakpoint-limit 6
    set breakpoint auto-hw on
    set displaced-stepping on

Indeed I hit a similar problem and found that 
memory::access_with_adjusted_size() has some issues, I could never 
finish the unit-tests but this is the first entry on my 2.11 TODO.

I'll send as RFC.

Regards,

Phil.
