[SOLVED] How do I tell gcc that my inline assembly clobbers part of the stack?

Issue

Consider inline assembly like this:

uint64_t flags;
asm ("pushf\n\tpop %0" : "=rm"(flags) : : /* ??? */);

Nonwithstanding the fact that there is probably some kind of intrinsic to get the contents of RFLAGS, how do I indicate to the compiler that my inline assembly clobbers one quadword of memory at the top of stack?

Solution

As far as I am concerned, this is currently not possible.
