[llvm-commits] [patch] Instcombine bug - transforms GEP/Bitcast on different address spaces

[Rotem, Nadav]

Hi,

Please review the attached patch.

The attached patch fixes a bug in InstCombine. The pass optimizes gep(bitcast ) even when the bitcasts casts away address space info. We crash with an assert in this case.

The attached patch checks that the address space of the bitcasted pointer is the same as the gep ptr.
