[Lightning] Understanding the jit_set_ip

[Mathieu Suen]

Hi

It is more a C related syntax question but here it is.

I don't understand what does it mean:
#define    jit_set_ip(ptr)            (_jit.x.pc = (ptr), jit_get_ip ())

Especially near the coma.

My guess is if we got:
a = jit_set_ip(foo);

it is going to be expand in:

_jit.x.pc = (foo);
a = jit_get_ip();

Thanks
