* [Libomptarget][NFCI] Move logic out of PluginAdaptorTy (#86971)Joseph Huber2024-03-292-61/+47
| | | | | | | | | | | Summary: This patch removes most of the special handling from the `PluginAdaptorTy` in preparation for changing this to be the `GenericPluginTy`. Doing this requires that the OpenMP specific handling of stuff like device offsets be contained within the OpenMP plugin manager. Generally this was uninvasive expect for the change to tracking the offset and size of the used devices. The eaiest way I could think to do this was to use some maps, which double as indicators for which plugins have devices active. This should not affect the logic.

* [RISCV] Combine (or disjoint ext, ext) -> vwadd (#86929)Luke Lau2024-03-292-17/+27
| | | | | | | | DAGCombiner (or InstCombine) will convert an add to an or if the bits are disjoint, which can prevent what was originally an (add {s,z}ext, {s,z}ext) from being selected as a vwadd. This teaches combineBinOp_VLToVWBinOp_VL to recover it by treating it as an add.

* [C++20] [Modules] [Reduced BMI] Don't record declarations in functionsChuanqi Xu2024-03-292-0/+37
| | | | | | | | | | | by default For reduced BMI, it is meaningless to record the local declarations in functions if not required explicitly during the process of writing the function bodies. It wastes time for reduced BMI and may be problematic if we want to avoid transiting unnecessary changes.
* [IR] Add nowrap flags for trunc instruction (#85592)elhewaty2024-03-2915-20/+281

* [RISCV][TypePromotion] Dont generate truncs if PromotedType is greater than ↵Sudharsan Veeravalli2024-03-282-1/+28
| | | | | | | | | | Source Type (#86941) We currently check if the source and promoted types are not equal before generating truncate instructions. This does not work for RV64 where the promoted type is i64 and this lead to a crash due to the generation of truncate instructions from i32 to i64. Fixes #86400

* [bazel] Fix lit tests with python 3.11+ (#87022)Keith Smiley2024-03-282-0/+2
| | | | | | | | | | | In python3.11 there is a new environment variable PYTHONSAFEPATH which stops python from setting the current directory as the first entry in sys.path. Bazel started setting this to ensure that python targets don't accidentally access things that aren't in their dependency tree. This resulted in lit tests breaking because sys.path didn't include the directory to the lit source files. This is fixed by adding the lit binary to the dependency tree and propagating the import path from it. Fixes https://github.com/llvm/llvm-project/issues/75963

* [scudo] Fix stack depot validation. (#87024)Christopher Ferris2024-03-281-1/+1
| | | | | | | In the StackDepot::isValid function, there is work to validate the TabMask variable. Unfortunately, if TabMask is set to the maximum allowed value, TabSize = TabMask + 1 becomes zero and validation passes. Disallow that case to prevent invalid reads into the Tab structure.
* [docs][TypeProf]Update instrumentation file format document (#83309)Mingming Liu2024-03-281-0/+53

* [APINotes][test] Fix permissions of a file copied from a source treeDmitri Gribenko2024-03-291-0/+1
| | | | | | | Our CI system makes the source tree read-only. The 'cp' command that copies a directory from the source tree into a temp directory preserves permissions, and the copied files stay read-only. When the test tries to append to one of these files, it fails with a "permission denied" error.
* [RISCV] Extend pattern matches involving shNadd to support disjoint or (#87001)Philip Reames2024-03-282-25/+114

* Reapply "[clang][nullability] allow _Nonnull etc on nullable class types ↵Sam McCall2024-03-2821-29/+226
| | | | | | | | | | | (#82705)" This reverts commit ca4c4a6758d184f209cb5d88ef42ecc011b11642. This was intended not to introduce new consistency diagnostics for smart pointer types, but failed to ignore sugar around types when detecting this. Fixed and test added.
* [LangRef] Try to clarify some Metadata semantics (#81948)Scott Linder2024-03-282-18/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | General cleanup in LangRef (and two outdated comments in LLParser.cpp) with the aim of making it easier to understand some of the terminology and subtle idiosyncrasies related to metadata in the IR. I'm still not happy with the fact that "node" is used both informally and with a particular category of metadata in mind, depending on the context. This also bleeds into the type names in the implementation. There are also several places where names from the implementation appear in the document with no other context or definition. In some cases I added a parenthetical to section titles to tie the two together, but I don't think this is ideal. I also think it might be useful to define the "abstract" metadata classes like "DIScope" in the document, so the hierarchy of metadata node kinds is direct, and so we can avoid repetitive descriptions of all of the members of on part of the hierarchy. This inheritance doesn't have to be in terms of C++ classes, but using the same names as the implementation seems helpful, and we already do it for many other things. Finally I added sections for the specialized nodes which are implemented in the IR but didn't have documentation in LangRef yet. These could use some work, and I admit I didn't dig too deep into the specifics beyond enumerating the fields, but I think we would ideally always have a LangRef section for every kind of node.
* [scudo] Dump ReleaseToOsIntervalMs (#86887)ChiaHungDuan2024-03-282-6/+9
| | | | This can be adjusted during runtime and it may impact the memory footprint if it's set to a big value or is disabled.
* [libc] Add inf/nan tests for strfrom*() functions (#86663)Vinayak Dev2024-03-282-7/+73
| | | | | | | Adds tests for `inf` and `nan` values to the tests for `strfrom*()` functions. Also marks some variables as `[[maybe_unused]]` to silence unused variable warnings.
* [APINotes] Make an assert in a std::sort call tolerate self-comparisonsDmitri Gribenko2024-03-281-1/+1
| | | | | | | | | | | | libc++ debug mode verifies that a comparator passed to std::sort defines a strict weak order by calling it with the same element. See also: - RFC that introduced the feature: https://discourse.llvm.org/t/rfc-strict-weak-ordering-checks-in-the-debug-libc/70217 - `strict_weak_ordering_check.h` in libc++ sources.
* [AArch64][GISEL] Consider fcmp true and fcmp false in cond code selection ↵Marc Auberer2024-03-283-0/+127
| | | | | | | | (#86972) Fixes #86917 `FCMP_TRUE` and `FCMP_FALSE` were previously not considered and we ended up in an llvm_unreachable assertion.
* [RISCV] Combine ({s,u}{div,rem} (zext, zext)) -> (zext ({s,u}{div,rem} ↵Luke Lau2024-03-292-18/+36
| | | | | | | | | | | | | | (zext, zext))) (#86779) This narrows unsigned and signed div and rem nodes via combineBinOpOfZExt. Unlike other binary ops, there are no widening div or rem instructions. So we will end up with an extra vzext.vf2. However I'm assuming that div/rem are expensive enough that by reducing their EMUL we will gain back the cost.

* [CodeGen/DWARF] Introduce DWARF tag for SwiftTail and emit it in CodeGen.Adrian Prantl2024-03-283-6/+5
| | | | | | | | | | swifttailcc is a new calling convention in LLVM introduced in https://reviews.llvm.org/D95443. We add a new DWARF tag to capture this in debuginfo. Differential Revision: https://reviews.llvm.org/D95704 [Note: This patch seems to have been forgotten about, landing it now with considerable delay]
* [MCP] Remove dead copies from basic blocks with successors. (#86973)Craig Topper2024-03-2813-43/+40
| | | | | | | | | | Previously we wouldn't remove dead copies from basic blocks with successors. The comment said we didn't want to trust the live-in lists. The comment is very old so I'm not sure if that's still a concern today. This patch checks the live-in lists and removes copies from MaybeDeadCopies if they are referenced by any live-ins in any successors. We only do this if the tracksLiveness property is set. If that property is not set, we retain the old behavior.
* [DXIL] Add lowering for `reversebits` and `trunc` (#86909)Helena Kotas2024-03-284-0/+67

* [memprof] Add MemProf version (#86414)Kazu Hirata2024-03-285-18/+91
| | | | | | | | | | | | This patch adds a version field to the MemProf section of the indexed profile format, calling the new version "version 1". The existing version is called "version 0". The writer supports both versions via a command-line option: llvm-profdata merge --memprof-version=1 ... The reader supports both versions by automatically detecting the version from the header.

* [lldb] Remove cmake check for pexpect with LLDB_TEST_USE_VENDOR_PACKAGES ↵Jordan Rupprecht2024-03-281-17/+0
| | | | | | | | | | | | | | | | | | (#86962) The commit 8bed754c2f965c8cbbb050be6f650b78f7fd78a6 was intended to support the use case where users want to run all the LLDB tests in an environment where pexpect is not installed. Those users can build with `-DLLDB_TEST_USER_ARGS=--skip-category=pexpect` to skip pexpect tests, *but* because we still fail in cmake configuration, they must use `-DLLDB_TEST_USE_VENDOR_PACKAGES=ON` to avoid failing due to pexpect not being available. I would like to remove `LLDB_TEST_USE_VENDOR_PACKAGES` now, but first I'd like to make sure users w/o pexpect can pass CI with `-DLLDB_TEST_USE_VENDOR_PACKAGES=OFF -DLLDB_TEST_USER_ARGS=--skip-category=pexpect`. Once that is done, I am not aware of any other issues caused by the previous commits, so the third party tree should be safe to remove.
