For PR1043: Bye, Bye Booly. Remove the use of the bool type from non-upgraded test cases and from grep expressions. The parser doesn't accept it and the asm writer doesn't produce it any more. llvm-svn: 33183

For PR950: The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. llvm-svn: 31931

For PR950: Update the test suite to accommodate the change from signed integer types to signless integer types. The changes were of only a few kinds: 1. Make sure llvm-upgrade is run on the source which does the bulk of the changes automatically. 2. Change things like "grep 'int'" to "grep 'i32'" 3. In several tests bitcasting caused the same name to be reused in the same type plane. These had to be manually fixed. The fix was (generally) to leave the bitcast and provide the instruction with a new name. This should not affect the semantics of the test. In a few cases, the bitcasts were known to be superfluous and irrelevant to the test case so they were removed. 4. One test case uses a bytecode file which needed to be updated to the latest bytecode format. llvm-svn: 32789

entry:
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

Enable MI Sched for x86. This changes the SelectionDAG scheduling preference to source order. Soon, the SelectionDAG scheduler can be bypassed saving a nice chunk of compile time. Performance differences that result from this change are often a consequence of register coalescing. The register coalescer is far from perfect. Bugs can be filed for deficiencies. On x86 SandyBridge/Haswell, the source order schedule is often preserved, particularly for small blocks. Register pressure is generally improved over the SD scheduler's ILP mode. However, we are still able to handle large blocks that require latency hiding, unlike the SD scheduler's BURR mode. MI scheduler also attempts to discover the critical path in single-block loops and adjust heuristics accordingly. The MI scheduler relies on the new machine model. This is currently unimplemented for AVX, so we may not be generating the best code yet. Unit tests are updated so they don't depend on SD scheduling heuristics. llvm-svn: 192750
