Joey Gouly	12a8bf09d0	[CGP] r205941 changed the logic, so that a cast happens before 'Result' is compared to 'AddrMode.BaseReg'. In the case that 'AddrMode.BaseReg' is nullptr, 'Result' will also be nullptr, so the cast causes an assertion. We should use dyn_cast_or_null here to check 'Result' is not null and it is an instruction. Bug found by Mats Petersson, and I reduced his IR to get a test case. llvm-svn: 208705	2014-05-13 15:42:45 +00:00

[CGP] r205941 changed the logic, so that a cast happens *before* 'Result' is

compared to 'AddrMode.BaseReg'. In the case that 'AddrMode.BaseReg' is
nullptr, 'Result' will also be nullptr, so the cast causes an assertion. We
should use dyn_cast_or_null here to check 'Result' is not null and it is an
instruction.

Bug found by Mats Petersson, and I reduced his IR to get a test case.
