New BranchProbabilityInfo analysis. Patch by Jakub Staszak! BranchProbabilityInfo provides an interface for IR passes to query the likelihood that control follows a CFG edge. This patch provides an initial implementation of static branch predication that will populate BranchProbabilityInfo for branches with no external profile information using very simple heuristics. It currently isn't hooked up to any external profile data, so static prediction does all the work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132613 91177308-0d34-0410-b5e6-96231b3b80d8

Added a late machine instruction copy propagation pass. This catches opportunities that only present themselves after late optimizations such as tail duplication .e.g. ## BB#1: movl %eax, %ecx movl %ecx, %eax ret The register allocator also leaves some of them around (due to false dep between copies from phi-elimination, etc.) This required some changes in codegen passes. Post-ra scheduler and the pseudo-instruction expansion passes have been moved after branch folding and tail merging. They were before branch folding before because it did not always update block livein's. That's fixed now. The pass change makes independently since we want to properly schedule instructions after branch folding / tail duplication. rdar://10428165 rdar://10640363 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147716 91177308-0d34-0410-b5e6-96231b3b80d8

Add an experimental early if-conversion pass, off by default. This pass performs if-conversion on SSA form machine code by speculatively executing both sides of the branch and using a cmov instruction to select the result. This can help lower the number of branch mispredictions on architectures like x86 that don't have predicable instructions. The current implementation is very aggressive, and causes regressions on mosts tests. It needs good heuristics that have yet to be implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159694 91177308-0d34-0410-b5e6-96231b3b80d8

Turn the EdgeBundles class into a stand-alone machine CFG analysis pass. The analysis will be needed by both the greedy register allocator and the X86FloatingPoint pass.

Stub out a new LiveDebugVariables pass. This analysis is going to run immediately after LiveIntervals. It will stay alive during register allocation and keep track of user variables mentioned in DBG_VALUE instructions. When the register allocator is moving values between registers and the stack, it is very hard to keep track of DBG_VALUE instructions. We usually get it wrong. This analysis maintains a data structure that makes it easy to update DBG_VALUE instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120385 91177308-0d34-0410-b5e6-96231b3b80d8

Sketch a LiveRegMatrix analysis pass. The LiveRegMatrix represents the live range of assigned virtual registers in a Live interval union per register unit. This is not fundamentally different from the interference tracking in RegAllocBase that both RABasic and RAGreedy use. The important differences are: - LiveRegMatrix tracks interference per register unit instead of per physical register. This makes interference checks cheaper and assignments slightly more expensive. For example, the ARM D7 reigster has 24 aliases, so we would check 24 physregs before assigning to one. With unit-based interference, we check 2 units before assigning to 2 units. - LiveRegMatrix caches regmask interference checks. That is currently duplicated functionality in RABasic and RAGreedy. - LiveRegMatrix is a pass which makes it possible to insert target-dependent passes between register allocation and rewriting. Such passes could tweak the register assignments with interference checking support from LiveRegMatrix. Eventually, RABasic and RAGreedy will be switched to LiveRegMatrix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158255 91177308-0d34-0410-b5e6-96231b3b80d8

void initializeLowerExpectIntrinsicPass(PassRegistry&);
Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize the pass's dependencies. Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h before parsing commandline arguments. I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass registration/creation, please send the testcase to me directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116820 91177308-0d34-0410-b5e6-96231b3b80d8

void initializeMachineBlockFrequencyInfoPass(PassRegistry&);
Implement a block placement pass based on the branch probability and block frequency analyses. This differs substantially from the existing block-placement pass in LLVM: 1) It operates on the Machine-IR in the CodeGen layer. This exposes much more (and more precise) information and opportunities. Also, the results are more stable due to fewer transforms ocurring after the pass runs. 2) It uses the generalized probability and frequency analyses. These can model static heuristics, code annotation derived heuristics as well as eventual profile loading. By basing the optimization on the analysis interface it can work from any (or a combination) of these inputs. 3) It uses a more aggressive algorithm, both building chains from tho bottom up to maximize benefit, and using an SCC-based walk to layout chains of blocks in a profitable ordering without O(N^2) iterations which the old pass involves. The pass is currently gated behind a flag, and not enabled by default because it still needs to grow some important features. Most notably, it needs to support loop aligning and careful layout of loop structures much as done by hand currently in CodePlacementOpt. Once it supports these, and has sufficient testing and quality tuning, it should replace both of these passes. Thanks to Nick Lewycky and Richard Smith for help authoring & debugging this, and to Jakob, Andy, Eric, Jim, and probably a few others I'm forgetting for reviewing and answering all my questions.

Start scaffolding for a MachineTraceMetrics analysis pass. This is still a work in progress. Out-of-order CPUs usually execute instructions from multiple basic blocks simultaneously, so it is necessary to look at longer traces when estimating the performance effects of code transformations. The MachineTraceMetrics analysis will pick a typical trace through a given basic block and provide performance metrics for the trace. Metrics will include: - Instruction count through the trace. - Issue count per functional unit. - Critical path length, and per-instruction 'slack'. These metrics can be used to determine the performance limiting factor when executing the trace, and how it will be affected by a code transformation. Initially, this will be used by the early if-conversion pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160796 91177308-0d34-0410-b5e6-96231b3b80d8

Introduce a new SROA implementation. This is essentially a ground up re-think of the SROA pass in LLVM. It was initially inspired by a few problems with the existing pass: - It is subject to the bane of my existence in optimizations: arbitrary thresholds. - It is overly conservative about which constructs can be split and promoted. - The vector value replacement aspect is separated from the splitting logic, missing many opportunities where splitting and vector value formation can work together. - The splitting is entirely based around the underlying type of the alloca, despite this type often having little to do with the reality of how that memory is used. This is especially prevelant with unions and base classes where we tail-pack derived members. - When splitting fails (often due to the thresholds), the vector value replacement (again because it is separate) can kick in for preposterous cases where we simply should have split the value. This results in forming i1024 and i2048 integer "bit vectors" that tremendously slow down subsequnet IR optimizations (due to large APInts) and impede the backend's lowering. The new design takes an approach that fundamentally is not susceptible to many of these problems. It is the result of a discusison between myself and Duncan Sands over IRC about how to premptively avoid these types of problems and how to do SROA in a more principled way. Since then, it has evolved and grown, but this remains an important aspect: it fixes real world problems with the SROA process today. First, the transform of SROA actually has little to do with replacement. It has more to do with splitting. The goal is to take an aggregate alloca and form a composition of scalar allocas which can replace it and will be most suitable to the eventual replacement by scalar SSA values. The actual replacement is performed by mem2reg (and in the future SSAUpdater). The splitting is divided into four phases. The first phase is an analysis of the uses of the alloca. This phase recursively walks uses, building up a dense datastructure representing the ranges of the alloca's memory actually used and checking for uses which inhibit any aspects of the transform such as the escape of a pointer. Once we have a mapping of the ranges of the alloca used by individual operations, we compute a partitioning of the used ranges. Some uses are inherently splittable (such as memcpy and memset), while scalar uses are not splittable. The goal is to build a partitioning that has the minimum number of splits while placing each unsplittable use in its own partition. Overlapping unsplittable uses belong to the same partition. This is the target split of the aggregate alloca, and it maximizes the number of scalar accesses which become accesses to their own alloca and candidates for promotion. Third, we re-walk the uses of the alloca and assign each specific memory access to all the partitions touched so that we have dense use-lists for each partition. Finally, we build a new, smaller alloca for each partition and rewrite each use of that partition to use the new alloca. During this phase the pass will also work very hard to transform uses of an alloca into a form suitable for promotion, including forming vector operations, speculating loads throguh PHI nodes and selects, etc. After splitting is complete, each newly refined alloca that is a candidate for promotion to a scalar SSA value is run through mem2reg. There are lots of reasonably detailed comments in the source code about the design and algorithms, and I'm going to be trying to improve them in subsequent commits to ensure this is well documented, as the new pass is in many ways more complex than the old one. Some of this is still a WIP, but the current state is reasonbly stable. It has passed bootstrap, the nightly test suite, and Duncan has run it successfully through the ACATS and DragonEgg test suites. That said, it remains behind a default-off flag until the last few pieces are in place, and full testing can be done. Specific areas I'm looking at next: - Improved comments and some code cleanup from reviews. - SSAUpdater and enabling this pass inside the CGSCC pass manager. - Some datastructure tuning and compile-time measurements. - More aggressive FCA splitting and vector formation. Many thanks to Duncan Sands for the thorough final review, as well as Benjamin Kramer for lots of review during the process of writing this pass, and Daniel Berlin for reviewing the data structures and algorithms and general theory of the pass. Also, several other people on IRC, over lunch tables, etc for lots of feedback and advice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163883 91177308-0d34-0410-b5e6-96231b3b80d8

While cleaning up declarations, cleaned up comments (sorry for large diff). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150100 91177308-0d34-0410-b5e6-96231b3b80d8

introduce a new TargetLibraryInfo pass, which transformations can use to query about available library functions. For now this just has memset_pattern16, which exists on darwin, but it can be extended for a bunch of other things in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125965 91177308-0d34-0410-b5e6-96231b3b80d8

Reintroduce VirtRegRewriter. OK, not really. We don't want to reintroduce the old rewriter hacks. This patch extracts virtual register rewriting as a separate pass that runs after the register allocator. This is possible now that CodeGen/Passes.cpp can configure the full optimizing register allocator pipeline. The rewriter pass uses register assignments in VirtRegMap to rewrite virtual registers to physical registers, and it inserts kill flags based on live intervals. These finalization steps are the same for the optimizing register allocators: RABasic, RAGreedy, and PBQP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158244 91177308-0d34-0410-b5e6-96231b3b80d8

Add a new convenience pass for testing InstructionSimplify. Previously it could only be tested indirectly, via instcombine, gvn or some other pass that makes use of InstructionSimplify, which means that testcases had to be carefully contrived to dance around any other transformations that that pass did. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122264 91177308-0d34-0410-b5e6-96231b3b80d8

- Add MachineInstrBundle.h and MachineInstrBundle.cpp. This includes a function to finalize MI bundles (i.e. add BUNDLE instruction and computing register def and use lists of the BUNDLE instruction) and a pass to unpack bundles. - Teach more of MachineBasic and MachineInstr methods to be bundle aware. - Switch Thumb2 IT block to MI bundles and delete the hazard recognizer hack to prevent IT blocks from being broken apart. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146542 91177308-0d34-0410-b5e6-96231b3b80d8

Add a basic-block autovectorization pass. This is the initial checkin of the basic-block autovectorization pass along with some supporting vectorization infrastructure.

Add an insertPass API to TargetPassConfig. <rdar://problem/11498613> Besides adding the new insertPass function, this patch uses it to enhance the existing -print-machineinstrs so that the MachineInstrs after a specific pass can be printed.
