[PM/ThinLTO] Port the ThinLTO pipeline (both components) to the new PM. Based on the original patch by Davide, but I've adjusted the API exposed to just be different entry points rather than exposing more state parameters. I've factored all the common logic out so that we don't have any duplicate pipelines, we just stitch them together in different ways. I think this makes the build easier to reason about and understand. This adds a direct method for getting the module simplification pipeline as well as a method to get the optimization pipeline. While not my express goal, this seems nice and gives a good place comment about the restrictions that are imposed on them. I did make some minor changes to the way the pipelines are structured here, but hopefully not ones that are significant or controversial: 1) I sunk the PGO indirect call promotion to only be run when we have PGO enabled (or as part of the special ThinLTO pipeline). 2) I made the extra GlobalOpt run in ThinLTO just happen all the time and at a slightly more powerful place (before we remove available externaly functions). This seems like general goodness and not a big compile time sink, so it didn't make sense to *only* use it in ThinLTO. Fewer differences in the pipeline makes everything simpler IMO. 3) I hoisted the ThinLTO stop point pre-link above the the RPO function attr inference. The RPO inference won't infer anything terribly meaningful pre-link (recursiveness?) so it didn't make a lot of sense. But if the placement of RPO inference starts to matter, we should move it to the canonicalization phase anyways which seems like a better place for it (and there is a FIXME to this effect!). But that seemed a bridge too far for this patch. If we ever need to parameterize these pipelines more heavily, we can always sink the logic to helper functions with parameters to keep those parameters out of the public API. But the changes above seemed minor that we could possible get away without the parameters entirely. I added support for parsing 'thinlto' and 'thinlto-pre-link' names in pass pipelines to make it easy to test these routines and play with them in larger pipelines. I also added a really basic manifest of passes test that will show exactly how the pipelines behave and work as well as making updates to them clear. Lastly, this factoring does introduce a nesting layer of module pass managers in the default pipeline. I don't think this is a big deal and the flexibility of decoupling the pipelines seems easily worth it. Differential Revision: https://reviews.llvm.org/D33540 llvm-svn: 304407

; The IR below was crafted so as:
; 1) To have a loop, so we create a loop pass manager
; 2) To be "immutable" in the sense that no pass in the standard
; pipeline will modify it.
; Since no transformations take place, we don't expect any analyses
; to be invalidated.
; Any invalidation that shows up here is a bug, unless we started modifying
; the IR, in which case we need to make it immutable harder.

Refine the PGOOpt and SamplePGOSupport handling. Summary: Now that SamplePGOSupport is part of PGOOpt, there are several places that need tweaking: 1. AddDiscriminator pass should *not* be invoked at ThinLTOBackend (as it's already invoked in the PreLink phase) 2. addPGOInstrPasses should only be invoked when either ProfileGenFile or ProfileUseFile is non-empty. 3. SampleProfileLoaderPass should only be invoked when SampleProfileFile is non-empty. 4. PGOIndirectCallPromotion should only be invoked in ProfileUse phase, or in ThinLTOBackend of SamplePGO.

Revert part of r310296 to make it really NFC for instrumentation PGO. Summary: Part of r310296 will disable PGOIndirectCallPromotion in ThinLTO backend if PGOOpt is None. However, as PGOOpt is not passed down to ThinLTO backend for instrumentation based PGO, that change would actually disable ICP entirely in ThinLTO backend, making it behave differently in instrumentation PGO mode. This change reverts that change, and only disable ICP there when it is SamplePGO.

[PM/ThinLTO] Port the ThinLTO pipeline (both components) to the new PM. Based on the original patch by Davide, but I've adjusted the API exposed to just be different entry points rather than exposing more state parameters. I've factored all the common logic out so that we don't have any duplicate pipelines, we just stitch them together in different ways. I think this makes the build easier to reason about and understand. This adds a direct method for getting the module simplification pipeline as well as a method to get the optimization pipeline. While not my express goal, this seems nice and gives a good place comment about the restrictions that are imposed on them. I did make some minor changes to the way the pipelines are structured here, but hopefully not ones that are significant or controversial: 1) I sunk the PGO indirect call promotion to only be run when we have PGO enabled (or as part of the special ThinLTO pipeline). 2) I made the extra GlobalOpt run in ThinLTO just happen all the time and at a slightly more powerful place (before we remove available externaly functions). This seems like general goodness and not a big compile time sink, so it didn't make sense to *only* use it in ThinLTO. Fewer differences in the pipeline makes everything simpler IMO. 3) I hoisted the ThinLTO stop point pre-link above the the RPO function attr inference. The RPO inference won't infer anything terribly meaningful pre-link (recursiveness?) so it didn't make a lot of sense. But if the placement of RPO inference starts to matter, we should move it to the canonicalization phase anyways which seems like a better place for it (and there is a FIXME to this effect!). But that seemed a bridge too far for this patch. If we ever need to parameterize these pipelines more heavily, we can always sink the logic to helper functions with parameters to keep those parameters out of the public API. But the changes above seemed minor that we could possible get away without the parameters entirely. I added support for parsing 'thinlto' and 'thinlto-pre-link' names in pass pipelines to make it easy to test these routines and play with them in larger pipelines.

Recommit r317351 : Add CallSiteSplitting pass This recommit r317351 after fixing a buildbot failure. Original commit message: Summary: This change add a pass which tries to split a call-site to pass more constrained arguments if its argument is predicated in the control flow so that we can expose better context to the later passes (e.g, inliner, jump threading, or IPA-CP based function cloning, etc.). As of now we support two cases : 1) If a call site is dominated by an OR condition and if any of its arguments are predicated on this OR condition, try to split the condition with more constrained arguments. For example, in the code below, we try to split the call site since we can predicate the argument (ptr) based on the OR condition. Split from : if (!ptr || c) callee(ptr); to : if (!ptr) callee(null ptr) // set the known constant value else if (c) callee(nonnull ptr) // set non-null attribute in the argument 2) We can also split a call-site based on constant incoming values of a PHI For example, from : BB0: %c = icmp eq i32 %i1, %i2 br i1 %c, label %BB2, label %BB1 BB1: br label %BB2 BB2: %p = phi i32 [ 0, %BB0 ], [ 1, %BB1 ] call void @bar(i32 %p) to BB0: %c = icmp eq i32 %i1, %i2 br i1 %c, label %BB2-split0, label %BB1 BB1: br label %BB2-split1 BB2-split0: call void @bar(i32 0) br label %BB2 BB2-split1: call void @bar(i32 1) br label %BB2 BB2: %p = phi i32 [ 0, %BB2-split0 ], [ 1, %BB2-split1 ] llvm-svn: 317362

Add CalledValuePropagation pass This patch adds a new pass for attaching !callees metadata to indirect call sites. The pass propagates values to call sites by performing an IPSCCP-like analysis using the generic sparse propagation solver. For indirect call sites having a small set of possible callees, the attached metadata indicates what those callees are. The metadata can be used to facilitate optimizations like intersecting the function attributes of the possible callees, refining the call graph, performing indirect call promotion, etc. Differential Revision: https://reviews.llvm.org/D37355 llvm-svn: 316576

A few notes: - isPromotionLegal is folded in the caller since we want to emit the Function in the remark but we can only do that if the symbol table look-up succeeded. - There was good test coverage for remarks in this pass. - promoteIndirectCall uses ORE conditionally since it's also used from SampleProfile which does not use ORE yet.

[PM/ThinLTO] Port the ThinLTO pipeline (both components) to the new PM. Based on the original patch by Davide, but I've adjusted the API exposed to just be different entry points rather than exposing more state parameters. I've factored all the common logic out so that we don't have any duplicate pipelines, we just stitch them together in different ways. I think this makes the build easier to reason about and understand. This adds a direct method for getting the module simplification pipeline as well as a method to get the optimization pipeline. While not my express goal, this seems nice and gives a good place comment about the restrictions that are imposed on them. I did make some minor changes to the way the pipelines are structured here, but hopefully not ones that are significant or controversial: 1) I sunk the PGO indirect call promotion to only be run when we have PGO enabled (or as part of the special ThinLTO pipeline). 2) I made the extra GlobalOpt run in ThinLTO just happen all the time and at a slightly more powerful place (before we remove available externaly functions). This seems like general goodness and not a big compile time sink, so it didn't make sense to *only* use it in ThinLTO. Fewer differences in the pipeline makes everything simpler IMO. 3) I hoisted the ThinLTO stop point pre-link above the the RPO function attr inference. The RPO inference won't infer anything terribly meaningful pre-link (recursiveness?) so it didn't make a lot of sense. But if the placement of RPO inference starts to matter, we should move it to the canonicalization phase anyways which seems like a better place for it (and there is a FIXME to this effect!).

[PM/LoopUnswitch] When using the new SimpleLoopUnswitch pass, schedule loop-cleanup passes at the beginning of the loop pass pipeline, and re-enqueue loops after even trivial unswitching. This will allow us to much more consistently avoid simplifying code while doing trivial unswitching. I've also added a test case that specifically shows effective iteration using this technique. I've unconditionally updated the new PM as that is always using the SimpleLoopUnswitch pass, and I've made the pipeline changes for the old PM conditional on using this new unswitch pass. I added a bunch of comments to the loop pass pipeline in the old PM to make it more clear what is going on when reviewing. Hopefully this will unblock doing *partial* unswitching instead of just full unswitching. Differential Revision: https://reviews.llvm.org/D47408 llvm-svn: 333493

[PM/ThinLTO] Port the ThinLTO pipeline (both components) to the new PM. Based on the original patch by Davide, but I've adjusted the API exposed to just be different entry points rather than exposing more state parameters. I've factored all the common logic out so that we don't have any duplicate pipelines, we just stitch them together in different ways. I think this makes the build easier to reason about and understand. This adds a direct method for getting the module simplification pipeline as well as a method to get the optimization pipeline. While not my express goal, this seems nice and gives a good place comment about the restrictions that are imposed on them. I did make some minor changes to the way the pipelines are structured here, but hopefully not ones that are significant or controversial: 1) I sunk the PGO indirect call promotion to only be run when we have PGO enabled (or as part of the special ThinLTO pipeline). 2) I made the extra GlobalOpt run in ThinLTO just happen all the time and at a slightly more powerful place (before we remove available externaly functions). This seems like general goodness and not a big compile time sink, so it didn't make sense to *only* use it in ThinLTO. Fewer differences in the pipeline makes everything simpler IMO. 3) I hoisted the ThinLTO stop point pre-link above the the RPO function attr inference. The RPO inference won't infer anything terribly meaningful pre-link (recursiveness?) so it didn't make a lot of sense. But if the placement of RPO inference starts to matter, we should move it to the canonicalization phase anyways which seems like a better place for it (and there is a FIXME to this effect!). But that seemed a bridge too far for this patch. If we ever need to parameterize these pipelines more heavily, we can always sink the logic to helper functions with parameters to keep those parameters out of the public API.

[DivRempairs] add a pass to optimize div/rem pairs (PR31028) This is intended to be a superset of the functionality from D31037 (EarlyCSE) but implemented as an independent pass, so there's no stretching of scope and feature creep for an existing pass. I also proposed a weaker version of this for SimplifyCFG in D30910. And I initially had almost this same functionality as an addition to CGP in the motivating example of PR31028: https://bugs.llvm.org/show_bug.cgi?id=31028 The advantage of positioning this ahead of SimplifyCFG in the pass pipeline is that it can allow more flattening. But it needs to be after passes (InstCombine) that could sink a div/rem and undo the hoisting that is done here. Decomposing remainder may allow removing some code from the backend (PPC and possibly others). Differential Revision: https://reviews.llvm.org/D37121 llvm-svn: 312862

Add a new pass to speculate around PHI nodes with constant (integer) operands when profitable. The core idea is to (re-)introduce some redundancies where their cost is hidden by the cost of materializing immediates for constant operands of PHI nodes. When the cost of the redundancies is covered by this, avoiding materializing the immediate has numerous benefits: 1) Less register pressure 2) Potential for further folding / combining 3) Potential for more efficient instructions due to immediate operand As a motivating example, consider the remarkably different cost on x86 of a SHL instruction with an immediate operand versus a register operand. This pattern turns up surprisingly frequently, but is somewhat rarely obvious as a significant performance problem. The pass is entirely target independent, but it does rely on the target cost model in TTI to decide when to speculate things around the PHI node. I've included x86-focused tests, but any target that sets up its immediate cost model should benefit from this pass. There is probably more that can be done in this space, but the pass as-is is enough to get some important performance on our internal benchmarks, and should be generally performance neutral, but help with more extensive benchmarking is always welcome. One awkward part is that this pass has to be scheduled after *everything* that can eliminate these kinds of redundancies. This includes SimplifyCFG, GVN, etc. I'm open to suggestions about better places to put this. We could in theory make it part of the codegen pass pipeline, but there doesn't really seem to be a good reason for that -- it isn't "lowering" in any sense and only relies on pretty standard cost model based TTI queries, so it seems to fit well with the "optimization" pipeline model. Still, further thoughts on the pipeline position are welcome. I've also only implemented this in the new pass manager. If folks are very interested, I can try to add it to the old PM as well, but I didn't really see much point (my use case is already switched over to the new PM). I've tested this pretty heavily without issue. A wide range of benchmarks internally show no change outside the noise, and I don't see any significant changes in SPEC either. However, the size class computation in tcmalloc is substantially improved by this, which turns into a 2% to 4% win on the hottest path through tcmalloc for us, so there are definitely important cases where this is going to make a substantial difference.
