ARM & AArch64: make use of common cmpxchg idioms after expansion The C and C++ semantics for compare_exchange require it to return a bool indicating success. This gets mapped to LLVM IR which follows each cmpxchg with an icmp of the value loaded against the desired value. When lowered to ldxr/stxr loops, this extra comparison is redundant: its results are implicit in the control-flow of the function. This commit makes two changes: it replaces that icmp with appropriate PHI nodes, and then makes sure earlyCSE is called after expansion to actually make use of the opportunities revealed. I've also added -{arm,aarch64}-enable-atomic-tidy options, so that existing fragile tests aren't perturbed too much by the change. Many of them either rely on undef/unreachable too pervasively to be restored to something well-defined (particularly while making sure they test the same obscure assert from many years ago), or depend on a particular CFG shape, which is disrupted by SimplifyCFG. rdar://problem/16227836 llvm-svn: 209883

PEI: Support for non-zero SPAdj at beginning of a basic block. We can have a FrameSetup in one basic block and the matching FrameDestroy in a different basic block when we have struct byval. In that case, SPAdj is not zero at beginning of the basic block. Modify PEI to correctly set SPAdj at beginning of each basic block using DFS traversal. We used to assume SPAdj is 0 at beginning of each basic block. PEI had an assert SPAdjCount || SPAdj == 0. If we have a Destroy <n> followed by a Setup <m>, PEI will assert failure. We can add an extra condition to make sure the pairs are matched: The pairs start with a FrameSetup. But since we are doing a much better job in the verifier, this patch removes the check in PEI.

Allocate local registers in order for optimal coloring. Also avoid locals evicting locals just because they want a cheaper register. Problem: MI Sched knows exactly how many registers we have and assumes they can be colored. In cases where we have large blocks, usually from unrolled loops, greedy coloring fails. This is a source of "regressions" from the MI Scheduler on x86. I noticed this issue on x86 where we have long chains of two-address defs in the same live range. It's easy to see this in matrix multiplication benchmarks like IRSmk and even the unit test misched-matmul.ll. A fundamental difference between the LLVM register allocator and conventional graph coloring is that in our model a live range can't discover its neighbors, it can only verify its neighbors. That's why we initially went for greedy coloring and added eviction to deal with the hard cases. However, for singly defined and two-address live ranges, we can optimally color without visiting neighbors simply by processing the live ranges in instruction order. Other beneficial side effects: It is much easier to understand and debug regalloc for large blocks when the live ranges are allocated in order. Yes, global allocation is still very confusing, but it's nice to be able to comprehend what happened locally. Heuristics could be added to bias register assignment based on instruction locality (think late register pairing, banks...). Intuituvely this will make some test cases that are on the threshold of register pressure more stable. llvm-svn: 187139

PEI: Support for non-zero SPAdj at beginning of a basic block. We can have a FrameSetup in one basic block and the matching FrameDestroy in a different basic block when we have struct byval. In that case, SPAdj is not zero at beginning of the basic block. Modify PEI to correctly set SPAdj at beginning of each basic block using DFS traversal. We used to assume SPAdj is 0 at beginning of each basic block. PEI had an assert SPAdjCount || SPAdj == 0. If we have a Destroy <n> followed by a Setup <m>, PEI will assert failure. We can add an extra condition to make sure the pairs are matched: The pairs start with a FrameSetup. But since we are doing a much better job in the verifier, this patch removes the check in PEI.
