As rustyx pointed out, Clang/LLVM (and gcc) provides __builtin_return_address()
which is equivalent to _ReturnAddress()
. Clang/LLVM also provides __builtin_frame_address()
which (depending on the particulars of your ABI, architecture, etc.) may be somewhat analogous to _AddressOfReturnAddress()
.
As an example, the following code...
std::cout<< ((int64_t) __builtin_return_address(0)) << ' '
<< ((int64_t) __builtin_frame_address (0)) << ' '
<<*((int64_t*)__builtin_frame_address (0)+1)<<'\n';
...prints the following on an OSX machine.
