New Revision: 374569
URL: http://llvm.org/viewvc/llvm-project?rev=374569&view=rev
Log:
Fix test failure with 374562 on Hexagon
__builtin_assume_aligned takes a size_t which is a 32 bit int on
hexagon. Thus, the constant gets converted to a 32 bit value, resulting
in 0 not being a power of 2. This patch changes the constant being
passed to 2**30 so that it fails, but doesnt exceed 30 bits.
