Pull in r227087 from upstream llvm trunk (by Vasileios Kalintiris): [mips] Add tests for bitwise binary and integer arithmetic operators. Reviewers: dsanders Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D7125 Pull in r227089 from upstream llvm trunk (by Vasileios Kalintiris): [mips] Enable arithmetic and binary operations for the i128 data type. Summary: This patch adds support for some operations that were missing from 128-bit integer types (add/sub/mul/sdiv/udiv... etc.). With these changes we can support the __int128_t and __uint128_t data types from C/C++. Depends on D7125 Reviewers: dsanders Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D7143 This fixes "error in backend" messages, when compiling parts of compiler-rt using 128-bit integer types for mips64.
