By the time RTL expansion happens, it appears that lvalue COND_EXPR's have
been re-arranged so that they are no longer lvalues in the tree
representation. An example of an lvalue COND_EXPR:
int bar(void);
void cond(int c, int *P1, int *P2) {
(c ? *P1 : *P2) = bar(); // LValue conditional
}
Is this transformation always guaranteed to be performed by the time RTL
expansion is done?
Thanks,
-Chris
