Hello all,
I was wondering if there is some means of directing gcc to generate
unreachable code? Either a means to do so globally or a specific
scope would be great. I wish to generate some code which employs
inline assembly and/or libunwind to do a type of exception handling
not possible in standard C.
Don't get me wrong - the compiler is correct. The generated code is
unreachable via any standard C control flow mechanism, but I'd really
like it to generate the code anyways. Is there any way to do this?
Put a label before the block of code, then take the address of the label
and pass it to a function defined in another compilation unit? That
should make the compiler think the code in question is reachable and
thus prevent it from being deleted.
