The patch adds support of i128 params lowering. The changes are quite trivial to support i128 as a "special case" of integer type. With this patch, we lower i128 params the same way as aggregates of size 16 bytes: .param .b8 _ [16]. Currently, NVPTX can't deal with the 128 bit integers: * in some cases because of failed assertions like ValVTs.size() == OutVals.size() && "Bad return value decomposition" * in other cases emitting PTX with .i128 or .u128 types (which are not valid [1]) [1] http://docs.nvidia.com/cuda/parallel-thread-execution/index.html#fundamental-types Differential Revision: https://reviews.llvm.org/D34555 Patch by: Denys Zariaiev (denys.zariaiev@gmail.com) llvm-svn: 308675
