For PR761: Remove "target endian/pointersize" or add "target datalayout" to make the test parse properly or set the datalayout because defaults changes. For PR645: Make global names use the @ prefix. For llvm-upgrade changes: Fix test cases or completely remove use of llvm-upgrade for test cases that cannot survive the new renaming or upgrade capabilities. llvm-svn: 33533

Changes to support making the shift instructions be true BinaryOperators. This feature is needed in order to support shifts of more than 255 bits on large integer types. This changes the syntax for llvm assembly to make shl, ashr and lshr instructions look like a binary operator: shl i32 %X, 1 instead of shl i32 %X, i8 1 Additionally, this should help a few passes perform additional optimizations. llvm-svn: 33776

Fix incorrect test cases for srem. The definition of srem is a remainder so that the sign of the result follows the sign of the divisor. llvm-svn: 35301
