[Qemu-devel] Questions on "hidden" functions in QEMU source code

[Jun Koi]

Hi,

I am looking at the source code of QEMU, and there are some mystery to
me: some functions are not defined anywhere.

For example, functions like compute_all_incb() and compute_c_incl() in
target-i386/op.c are never defined anywhere.

So how the compilation process generates these functions?

Another question: micro-op are defined as OPPROTO, but OPPROTO is
actually defined as empty in dyngen-exec.h

#define OPPROTO

So what is the point of using OPPROTO here? I am sure that there is a
good reason to do that, but cannot figure it out.

Many thanks,
Jun
