[Qemu-devel] Signal handling for i386-darwin-user on Mac Intel

[Ilya Shar]

Thanks to pointers/patches from Mike and Pierre, I can
build i386-darwin-user binary.  There is a glitch
though with signal-handling.  The following fragment
in cpu_signal_handler() in cpu-exec.c 

    pc = uc->uc_mcontext.gregs[REG_EIP];
    trapno = uc->uc_mcontext.gregs[REG_TRAPNO];

appears to be Linux-specific and gives compilation
errors on a Mac:

/Users/ilya/tmp/feb4/qemu_cvs_user/qemu/cpu-exec.c: In
function 'cpu_x86_signal_handler':
/Users/ilya/tmp/feb4/qemu_cvs_user/qemu/cpu-exec.c:1307:
error: request for member 'gregs' in something not a
structure or union
/Users/ilya/tmp/feb4/qemu_cvs_user/qemu/cpu-exec.c:1307:
error: 'EIP' undeclared (first use in this function)
... 

When I dummy-out cpu_signal_handler() the binary
compiles, but I cannot run anything because the
signals are not handled. 

Is there a patch/solution to this?  

Thanks again for your help! 
Ilya
