2025-05-26[llvm] Remove unused includes (NFC) (#141526)Kazu Hirata
These are identified by misc-include-cleaner. I've filtered out those that break builds. Also, I'm staying away from llvm-config.h, config.h, and Compiler.h, which likely cause platform- or compiler-specific build failures.
2025-04-17[llvm] Use llvm::binary_search (NFC) (#136228)Kazu Hirata
2024-03-19[NFC][RemoveDIs] Use iterators for insertion at various call-sites (#84736)Jeremy Morse
These are the last remaining "trivial" changes to passes that use Instruction pointers for insertion. All of this should be NFC, it's just changing the spelling of how we identify a position. In one or two locations, I'm also switching uses of getNextNode etc to using std::next with iterators. This too should be NFC. --------- Merged by: Stephen Tozer <stephen.tozer@sony.com>
2022-11-14[TableGen] Use MemoryEffects to represent intrinsic memory effects (NFCI)Nikita Popov
The TableGen implementation was using a homegrown implementation of FunctionModRefInfo. This switches it to use MemoryEffects instead. This makes the code simpler, and will allow exposing the full representational power of MemoryEffects in the future. Among other things, this will allow us to map IntrHasSideEffects to an inaccessiblemem readwrite, rather than just ignoring it entirely in most cases. To avoid layering issues, this moves the ModRef.h header from IR to Support, so that it can be included in the TableGen layer. Differential Revision: https://reviews.llvm.org/D137641
2022-11-04[IR] Switch everything to use memory attributeNikita Popov
This switches everything to use the memory attribute proposed in https://discourse.llvm.org/t/rfc-unify-memory-effect-attributes/65579. The old argmemonly, inaccessiblememonly and inaccessiblemem_or_argmemonly attributes are dropped. The readnone, readonly and writeonly attributes are restricted to parameters only. The old attributes are auto-upgraded both in bitcode and IR. The bitcode upgrade is a policy requirement that has to be retained indefinitely. The IR upgrade is mainly there so it's not necessary to update all tests using memory attributes in this patch, which is already large enough. We could drop that part after migrating tests, or retain it longer term, to make it easier to import IR from older LLVM versions. High-level Function/CallBase APIs like doesNotAccessMemory() or setDoesNotAccessMemory() are mapped transparently to the memory attribute. Code that directly manipulates attributes (e.g. via AttributeList) on the other hand needs to switch to working with the memory attribute instead.

2021-06-17Update @llvm.powi to handle different int sizes for the exponentBjorn Pettersson
This can be seen as a follow up to commit 0ee439b705e82a4fe20e2, that changed the second argument of __powidf2, __powisf2 and __powitf2 in compiler-rt from si_int to int. That was to align with how those runtimes are defined in libgcc. One thing that seem to have been missing in that patch was to make sure that the rest of LLVM also handle that the argument now depends on the size of int (not using the si_int machine mode for 32-bit). When using __builtin_powi for a target with 16-bit int clang crashed. And when emitting libcalls to those rtlib functions, typically when lowering @llvm.powi), the backend would always prepare the exponent argument as an i32 which caused miscompiles when the rtlib was compiled with 16-bit int. The solution used here is to use an overloaded type for the second argument in @llvm.powi. This way clang can use the "correct" type when lowering __builtin_powi, and then later when emitting the libcall it is assumed that the type used in @llvm.powi matches the rtlib function. One thing that needed some extra attention was that when vectorizing calls several passes did not support that several arguments could be overloaded in the intrinsics. This patch allows overload of a scalar operand by adding hasVectorInstrinsicOverloadedScalarOpd, with an entry for powi. Differential Revision: https://reviews.llvm.org/D99439

2020-01-28Make llvm::StringRef to std::string conversions explicit.Benjamin Kramer
This is how it should've been and brings it more in line with std::string_view. There should be no functional change here. This is mostly mechanical from a custom clang-tidy check, with a lot of manual fixups. It uncovers a lot of minor inefficiencies. This doesn't actually modify StringRef yet, I'll do that in a follow-up.
2019-02-01[opaque pointer types] Add a FunctionCallee wrapper type, and use it.James Y Knight
Recommit r352791 after tweaking DerivedTypes.h slightly, so that gcc doesn't choke on it, hopefully. Original Message: The FunctionCallee type is effectively a {FunctionType*,Value*} pair, and is a useful convenience to enable code to continue passing the result of getOrInsertFunction() through to EmitCall, even once pointer types lose their pointee-type. Then: - update the CallInst/InvokeInst instruction creation functions to take a Callee, - modify getOrInsertFunction to return FunctionCallee, and - update all callers appropriately. One area of particular note is the change to the sanitizer code. Previously, they had been casting the result of `getOrInsertFunction` to a `Function*` via `checkSanitizerInterfaceFunction`, and storing that. That would report an error if someone had already inserted a function declaraction with a mismatching signature. However, in general, LLVM allows for such mismatches, as `getOrInsertFunction` will automatically insert a bitcast if needed. As part of this cleanup, cause the sanitizer code to do the same. (It will call its functions using the expected signature, however they may have been declared.) Finally, in a small number of locations, callers of `getOrInsertFunction` actually were expecting/requiring that a brand new function was being created. In such cases, I've switched them to Function::Create instead. Differential Revision: https://reviews.llvm.org/D57315 llvm-svn: 352827

2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth
to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
2019-01-10[opaque pointer types] Remove some calls to generic Type subtype accessors.James Y Knight
That is, remove many of the calls to Type::getNumContainedTypes(), Type::subtypes(), and Type::getContainedType(N). I'm not intending to remove these accessors -- they are useful/necessary in some cases. However, removing the pointee type from pointers would potentially break some uses, and reducing the number of calls makes it easier to audit. llvm-svn: 350835
2018-05-14Rename DEBUG macro to LLVM_DEBUG.Nicola Zaghen
The DEBUG() macro is very generic so it might clash with other projects. The renaming was done as follows: - git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g' - git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM - Manual change to APInt - Manually chage DOCS as regex doesn't match it. In the transition period the DEBUG() macro is still present and aliased to the LLVM_DEBUG() one. Differential Revision: https://reviews.llvm.org/D43624 llvm-svn: 332240

2017-05-18[LegacyPassManager] Remove TargetMachine constructorsFrancis Visoiu Mistrih
This provides a new way to access the TargetMachine through TargetPassConfig, as a dependency. The patterns replaced here are: * Passes handling a null TargetMachine call `getAnalysisIfAvailable<TargetPassConfig>`. * Passes not handling a null TargetMachine `addRequired<TargetPassConfig>` and call `getAnalysis<TargetPassConfig>`. * MachineFunctionPasses now use MF.getTarget(). * Remove all the TargetMachine constructors. * Remove INITIALIZE_TM_PASS. This fixes a crash when running `llc -start-before prologepilog`. PEI needs StackProtector, which gets constructed without a TargetMachine by the pass manager. The StackProtector pass doesn't handle the case where there is no TargetMachine, so it segfaults. Related to PR30324. Differential Revision: https://reviews.llvm.org/D33222 llvm-svn: 303360

2017-03-21Rename AttributeSet to AttributeListReid Kleckner
Summary: This class is a list of AttributeSetNodes corresponding the function prototype of a call or function declaration. This class used to be called ParamAttrListPtr, then AttrListPtr, then AttributeSet. It is typically accessed by parameter and return value index, so "AttributeList" seems like a more intuitive name. Rename AttributeSetImpl to AttributeListImpl to follow suit. It's useful to rename this class so that we can rename AttributeSetNode to AttributeSet later. AttributeSet is the set of attributes that apply to a single function, argument, or return value.

2015-10-21[mips][mips16] Re-work the inline assembly stubs to work with IAS. NFC.Daniel Sanders
Summary: Previously, we were inserting an InlineAsm statement for each line of the inline assembly. This works for GAS but it triggers prologue/epilogue emission when IAS is in use. This caused: .set noreorder .cpload $25 to be emitted as: .set push .set reorder .set noreorder .set pop .set push .set reorder .cpload $25 .set pop which led to assembler errors and caused the test to fail. The whitespace-after-comma changes included in this patch are necessary to match the output when IAS is in use.

2014-12-17[mips] Set GCC-compatible MIPS asssembler options before inline asm blocks.Toma Tabacu
Summary: When generating MIPS assembly, LLVM always overrides the default assembler options by emitting the '.set noreorder', '.set nomacro' and '.set noat' directives, while GCC uses the default options if an assembly-level function contains inline assembly code. This becomes a problem when the code generated by LLVM is interleaved with inline assembly which assumes GCC-like assembler options (from Linux, for example). This patch fixes these conflicts by setting the appropriate assembler options at the beginning of an inline asm block and popping them at the end.

2014-02-14This patch has two main functions:Reed Kotler
1) Fix a specific bug when certain conversion functions are called in a program compiled as mips16 with hard float and the program is linked as c++. There are two libraries that are reversed in the link order with gcc/g++ and clang/clang++ for mips16 in this case and the proper stubs will then not be called. These stubs are normally handled in the Mips16HardFloat pass but in this case we don't know at that time that we need to generate the stubs. This must all be handled later in code generation and we have moved this functionality to MipsAsmPrinter. When linked as C (gcc or clang) the proper stubs are linked in from libc. 2) Set up the infrastructure to handle 90% of what is in the Mips16HardFloat pass in this new area of MipsAsmPrinter. This is a more logical place to handle this and we have known for some time that we needed to move the code later and not implement it using inline asm as we do now but it was not clear exactly where to do this and what mechanism should be used. Now it's clear to us how to do this and this patch contains the infrastructure to move most of this to MipsAsmPrinter but the actual moving will be done in a follow on patch. The same infrastructure is used to fix this current bug as described in #1. This change was requested by the list during the original putback of the Mips16HardFloat pass but was not practical for us do at that time. llvm-svn: 201426
