One alternative\nwould be to define the enum in struct, and have SCEV inherit from it.\n\nThe patch also clarifies that the SCEVUse flags encode NUW/NSW, and\nhides getInt, setInt, etc to avoid potential mis-use.\n\nPR: https://github.com/llvm/llvm-project/pull/190199\nGitOrigin-RevId: ff4c6fe24ecb7857d119fe4bcaa8189f755973d7\n" }, { "commit": "3ddc81c995c4d3d5168c731e8cb6a703ece09583", "tree": "1b4e815f531f0c8b3f3d50def6db22bf8b16ba69", "parents": [ "0dc49b0d99cdc5fe86f810d18359ee4a6da8aa2b" ], "author": { "name": "Michael Kruse", "email": "llvm-project@meinersbur.de", "time": "Sat Apr 04 15:20:15 2026 +0200" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Sat Apr 04 06:25:26 2026 -0700" }, "message": "[Polly][NFC] Convert ScopBuilder::getPwAff() to isl++ (#190458)\n\nGitOrigin-RevId: fb3fada084c100bbba711a259cc795f110fa8bff\n" }, { "commit": "0dc49b0d99cdc5fe86f810d18359ee4a6da8aa2b", "tree": "f62fb36395ae8a53e0d50cd439355af006090bcd", "parents": [ "68494dc23d105f0e909b0555c3b695f1b4262352" ], "author": { "name": "Michael Kruse", "email": "llvm-project@meinersbur.de", "time": "Sat Apr 04 14:49:13 2026 +0200" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Sat Apr 04 05:50:45 2026 -0700" }, "message": "[Polly][NFC] Use factory pattern (#190456)\n\nTo (theoretically) reduce coupling of Scop and ScopBuilder.\n\nGitOrigin-RevId: 47d80039483c60040d0931df69813e15480ff7b2\n" }, { "commit": "68494dc23d105f0e909b0555c3b695f1b4262352", "tree": "750e02123f6377291236a7e7edec899b6762513e", "parents": [ "16217cd410072eef0cf818fa7f77570bd414328f" ], "author": { "name": "Michael Kruse", "email": "llvm-project@meinersbur.de", "time": "Sat Apr 04 13:42:04 2026 +0200" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Sat Apr 04 04:45:34 2026 -0700" }, "message": "[Polly] Assumptions used to derive domain must not be pruned by that domain (#190436)\n\nThe code that emits the conditions for whether a statement is executed\nby checking whether we are in the statement\u0027s domain may apply\nassumptions (such as an integer truncation being reversible).

This is useful when, e.g., internal headers are\nused in the PCH or the used headers are unlikely to provide benefits for\ndependants.\n\n* Precompiled headers are only used for C++ sources, not for C.\n\n* With GCC, PCH provide very little benefits (tested with GCC 14 and 15)\ndue to increased template instatiation costs, but substantially increase\nmax-rss and build directory size. Therefore, disable PCH with GCC by\ndefault; this can be explicitly overridden on the command line with\n-DCMAKE_DISABLE_PRECOMPILE_HEADERS\u003dOFF.\n\n* With ccache and non-Clang compilers, changes in macro definitions are\nnot always accurately forwarded with ccache\u0027s preprocessed mode. To be\non the safe side, when ccache is enabled, disable PCH with all non-Clang\ncompilers; this can be explicitly overridden.\n\n* With sccache, changes in macro definitions are not identified, which\nin some cases can lead to false positive cache hits. Conservatively\ndisable PCH with sccache by default.\n\n* Add a base PCH to LLVMSupport, which includes widely used standard\nlibrary and Support+ADT headers. The pch.h is placed in include so that\nlater PCH headers can extend that list of headers.\n\n* Flang PCH use is ported to the general mechanism.\n\nAddition of PCH headers for other components (e.g., IR, CodeGen) will be\nposted as separate PRs.\n\nRFC:\nhttps://discourse.llvm.org/t/rfc-use-pre-compiled-headers-to-speed-up-llvm-build-by-1-5-2x/89345\nGitOrigin-RevId: b82c7fc65229c8b2b6a964f023f6ec59b3cf9210\n" }, { "commit": "abc2d48b1e6c879695f26200d4d0ba21f3882045", "tree": "58618cee624f0cac76ee4007bf9438cad9f6529f", "parents": [ "4e1ddf66946532ab6a018c52ab40c996c535abb8" ], "author": { "name": "Michael Kruse", "email": "llvm-project@meinersbur.de", "time": "Mon Feb 16 23:28:51 2026 +0100" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Mon Feb 16 14:31:52 2026 -0800" }, "message": "[Polly][ScopInfo] Lazy Scop instantiation (#179535)\n\nThe old NPM was using ScopInfo pass introduced in\nhttps://reviews.llvm.org/D20962, which in contrast to the LPM was using\nScopInfoRegionPass.

The corresponding\nllvm-zorg PR is https://github.com/llvm/llvm-zorg/pull/648.\n\nUsing polly-x86_64-linux-test-suite as a proof-of-concept because that\nbuilder is currently offline, I am its maintainer, and is easier to\nbuild than an configuration supporting offload. Once the design has been\ndecided, more builders can follow.\n\nAdvantages are:\n* It is easier to make changes in the llvm-project repository. There are\n more reviewers than for the llvm-zorg repository.\n* Buildbot changes can be made in the same PR with changes that require\n updating the buildbot, e.g. changing the name of a CMake option.\n* Configuration changes take effect immeditately when landing; no\n buildbot master restart needed.\n* Some builders store a CMake cache file in the llvm-project repository\n for the reasons above. However, the number of changes that can be made\n with a CMake cache file alone are limited.\n\nCompared to AnnotatedBuilder, advantages are:\n* Reproducing a buildbot configuration locally made easy: just execute\n the script in-place. No llvm-zorg, local buildbot worker, or buildbot\n master needed.\n* Same for testing a change of a builder before landing it in llvm-zorg.\n Doing so with an AnnotatedBuilder requires two llvm-zorg checkouts:\n One for making the change of the builder script itself, which then is\n pushed to a private llvm-zorg branch on GitHub, and a second that is\n modified to fetch that branch instead of\n https://github.com/llvm/llvm-zorg/tree/main.\n* The AnnotatedBuilder scripts are located in the llvm-zorg repository\n and the buildbot-workers always checkout is always the top-of-trunk.\n This means that a buildbot configuration is split over three checkouts:\n * The checkout of llvm-project to be tested\n * The checkout of llvm-zorg by the buildbot-worker fetches; always the\n top-of-trunk, i.e may not match the revision of llvm-project that is\n executed (such as the CMake cache files located there), especially when\n using the \"Force build\" feature.\n * The checkout of llvm-zorg that the buildbot-master is running, which\n is updated only when the master is manually restarted.\n* The \"Force Build\" feature also allows for test-building any\n llvm-project PR. This is correctly handled by zorg\u0027s\n `addGetSourcecodeSteps`, but does not work with AnnotatedBuilders that\n checkout the llvm-project source on their own.\n\nThe goal is to move as much as possible into the llvm-project repository\nsuch that there cannot be a mismatch between checkouts of different\nrepositories. Ideally, the buildbot-master only needs to be\nupdated+restarted for adding/removing workers, not for build\nconfiguration changes.\n\n---------\n\nCo-authored-by: Jan Patrick Lehr \u003cjp.lehr@gmail.com\u003e\nGitOrigin-RevId: c55c2ab8067eef649a8b04fc8173b8e164cb56b3\n" }, { "commit": "929d2dc5c246f91761f75d8c9bb693569fe9462d", "tree": "43e34db195eb7a7c9bf08757a1e80158d0be0e6b", "parents": [ "aca96dd68b03ad3be8a89652b847a80d271f175f" ], "author": { "name": "Michael Kruse", "email": "llvm-project@meinersbur.de", "time": "Tue Jan 06 14:07:03 2026 +0100" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Tue Jan 06 05:11:48 2026 -0800" }, "message": "[Polly] Allow changing array dims when importing JScop (#174582)\n\nThis is in preparation to avoid relying on GEPs to derive dependency\ninformation; Clang will eventually emit `ptradd` instead of\n`getelementptr`.\n\nGitOrigin-RevId: af3a0e61f4e08afb53d4efe815fcc6269c63f739\n" }, { "commit": "aca96dd68b03ad3be8a89652b847a80d271f175f", "tree": "dafd0370bdaa05cbed9192158f9534a326ed9203", "parents": [ "c698d477b26a69781713df5e3116eff76a606813" ], "author": { "name": "Alexis Engelke", "email": "engelke@in.tum.de", "time": "Mon Dec 22 18:11:34 2025 +0100" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Mon Dec 22 09:15:57 2025 -0800" }, "message": "[LLVM][NFC] Move PassPlugin from Passes to separate library\n\nThis avoid pulling in the entire Passes library with all passes as\ndependencies when just referring to PassPlugin, which is in fact\nindependent of the Passes themselves.\n\nPull Request: https://github.com/llvm/llvm-project/pull/173279\n\nGitOrigin-RevId: f54df0d09e19ec6b205cb0af45c7ecea2fd8aeff\n" }, { "commit": "c698d477b26a69781713df5e3116eff76a606813", "tree": "5c8a2a276e99769481c67561afc79ca12b3b3c34", "parents": [ "d8fc42d930cdb8f0f9b79dc0e57e4dbe1dc4f5c6" ], "author": { "name": "Alexis Engelke", "email": "engelke@in.tum.de", "time": "Mon Dec 22 15:50:28 2025 +0000" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Mon Dec 22 07:55:50 2025 -0800" }, "message": "Revert \"[LLVM][NFC] Move PassPlugin from Passes to Extensions lib\" and subsequent commit\n\nThis reverts commit d87b47d3a893b849cfd1ee5309b9fec2b0aec8cd.\nThis reverts commit f7ed3d44a198bfe689a1aa284452e875d5bb8a55.\n\nGitOrigin-RevId: 2634a2bda1db92ab5324a47459ee7f23e531ce53\n" }, { "commit": "d8fc42d930cdb8f0f9b79dc0e57e4dbe1dc4f5c6", "tree": "018772c66dfd847d0f8e11cdc0b82337b767a3e6", "parents": [ "338c6764d24eadb0fa828e72d6c41aedaf5b8d50" ], "author": { "name": "Alexis Engelke", "email": "engelke@in.tum.de", "time": "Mon Dec 22 11:42:27 2025 +0100" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Mon Dec 22 02:45:55 2025 -0800" }, "message": "[LLVM][NFC] Move PassPlugin from Passes to Extensions lib\n\nThis avoid pulling in the entire Passes library with all passes as\ndependencies when just referring to PassPlugin, which is in fact\nindependent of the Passes themselves.\n\nPull Request: https://github.com/llvm/llvm-project/pull/172478\n\nGitOrigin-RevId: d87b47d3a893b849cfd1ee5309b9fec2b0aec8cd\n" }, { "commit": "338c6764d24eadb0fa828e72d6c41aedaf5b8d50", "tree": "5c8a2a276e99769481c67561afc79ca12b3b3c34", "parents": [ "583472acf677b65fc6e090664a400521ce3a2a4a" ], "author": { "name": "Michael Kruse", "email": "llvm-project@meinersbur.de", "time": "Wed Dec 17 13:20:19 2025 +0100" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Wed Dec 17 04:25:32 2025 -0800" }, "message": "[Polly] Recalculate dependencies after import-jscop (#172640)\n\nThe new access functions may have different dependencies than the\noriginal ones.

This\nis necessary because all (static) allocas are hoisted into the entry\nblock, so lifetime markers are the only way to convey the actual\nlifetimes.\n\nHowever, lifetime.start and lifetime.end are currently *allowed* to be\nused on non-alloca pointers. We don\u0027t actually do this in practice, but\njust the mere fact that this is possible breaks the core purpose of the\nlifetime markers, which is stack coloring of allocas. Stack coloring can\nonly work correctly if all lifetime markers for an alloca are\nanalyzable.\n\n* If a lifetime marker may operate on multiple allocas via a select/phi,\nwe don\u0027t know which lifetime actually starts/ends and handle it\nincorrectly (https://github.com/llvm/llvm-project/issues/104776).\n* Stack coloring operates on the assumption that all lifetime markers\nare visible, and not, for example, hidden behind a function call or\nescaped pointer. It\u0027s not possible to change this, as part of the\npurpose of lifetime markers is that they work even in the presence of\nescaped pointers, where simple use analysis is insufficient.\n\nI don\u0027t think there is any way to have coherent semantics for lifetime\nmarkers on allocas, while also permitting them on arbitrary pointer\nvalues.\n\nThis PR restricts lifetimes to operate on allocas only. As a followup, I\nwill also drop the size argument, which is superfluous if we always\noperate on an alloca. (This change also renders various code handling\nlifetime markers on non-alloca dead. I plan to clean up that kind of\ncode after dropping the size argument as well.)\n\nIn practice, I\u0027ve only found a few places that currently produce\nlifetimes on non-allocas:\n\n* CoroEarly replaces the promise alloca with the result of an intrinsic,\nwhich will later be replaced back with an alloca. I think this is the\nonly place where there is some legitimate loss of functionality, but I\ndon\u0027t think this is particularly important (I don\u0027t think we\u0027d expect\nthe promise in a coroutine to admit useful lifetime optimization.)\n* SafeStack moves unsafe allocas onto a separate frame. We can safely\ndrop lifetimes here, as SafeStack performs its own stack coloring.\n* Similar for AddressSanitizer, it also moves allocas into separate\nmemory.\n* LSR sometimes replaces the lifetime argument with a GEP chain of the\nalloca (where the offsets ultimately cancel out). This is just\nunnecessary. (Fixed separately in\nhttps://github.com/llvm/llvm-project/pull/149492.)\n* InferAddrSpaces sometimes makes lifetimes operate on an addrspacecast\nof an alloca.

In the original patch, the Use\u0027s\nuse list was replaced with an unsigned* to the reference count in the value. This\nversion leaves them as null and leaves the ref counting only in Value.\n\nRemove use-lists from instances of ConstantData (which are shared\nacross modules and have no operands).\n\nTo continue supporting most of the use-list API, store a ref-count in\nplace of the use-list; this is for API like Value::use_empty and\nValue::hasNUses. Operations that actually need the use-list -- like\nValue::use_begin -- will assert.\n\nThis change has three benefits:\n\n 1. The compiler output cannot in any way depend on the use-list order\n of instances of ConstantData.\n\n 2. There\u0027s no use-list traffic when adding and removing simple\n constants from operand lists (although there is ref-count traffic;\n YMMV).\n\n 3. It\u0027s cheaper to serialize use-lists (since we\u0027re no longer\n serializing the use-list order of things like i32 0).\n\nThe downside is that you can\u0027t look at all the users of ConstantData,\nbut traversals of users of i32 0 are already ill-advised.\n\nPossible follow-ups:\n - Track if an instance of a ConstantVector/ConstantArray/etc. is known\n to have all ConstantData arguments, and drop the use-lists to\n ref-counts in those cases. Callers need to check Value::hasUseList\n before iterating through the use-list.\n - Remove even the ref-counts. I\u0027m not sure they have any benefit\n besides minimizing the scope of this commit, and maintaining the\n counts is not free.\n\nFixes #58629\n\nCo-authored-by: Duncan P. N.
