Yaxun Liu 7bae0ef103 Fix known zero bits for addrspacecast. ... Currently LLVM assumes that a pointer addrspacecasted to a different addr space is equivalent to trunc or zext bitwise, which is not true. For example, in amdgcn target, when a null pointer is addrspacecasted from addr space 4 to 0, its value is changed from i64 0 to i32 -1. This patch teaches LLVM not to assume known bits of addrspacecast instruction to its operand. Differential Revision: https://reviews.llvm.org/D26803 llvm-svn: 287545		2016-11-21 15:42:31 +00:00
