This is important for ARM register pair hints. - Register allocator should resolve the second part of the hint (register number) before passing it to the target since it knows virtual register to physical register mapping. - More fixes to get ARM load / store double word working. llvm-svn: 73671

| | | | | | | | | | | | | | | move loads back past a check that the load address is valid, see new testcase. The test that went in with 72661 has exactly this case, except that the conditional it's moving past is checking something else; I've settled for changing that test to reference a global, not a pointer. It may be possible to scan all the tests you pass and make sure none of them are checking any component of the address, but it's not trivial and I'm not trying to do that here. llvm-svn: 73632

Try attached .bc with llvm-ld. assert(New->getType() == getType() && "replaceAllUses of value with new value of different type!"); Since stack is always on address space zero, I don't think that type of GV in a different address space is ever going to match. The other way is to allow replaceAllUsesWith to ignore address spaces while comparing types. (do we have a way to do that ?). But then such an optimization may fail the entire idea of user wanting to place a variable into different memory space. The original idea of user might be to save on the stack space (data memory) and hence he asked the variable to be placed into different memory space (program memory). So the best bet here is to deny this optimization by checking GV->getType()->getAddressSpace() == 0. llvm-svn: 73605
