2019-08-15[llvm] Migrate llvm::make_unique to std::make_uniqueJonas Devlieghere1-3/+3
Now that we've moved to C++14, we no longer need the llvm::make_unique implementation from STLExtras.h. This patch is a mechanical replacement of (hopefully) all the llvm::make_unique instances across the monorepo. llvm-svn: 369013
2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth1-4/+3
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
2018-08-20[PSV] Update API to be able to use TargetCustom without UB.Marcello Maggioni1-2/+2
getTargetCustom() requires values for "Kind" in the constructor that are not in the PSVKind enum. Passing a value that is not inside an enum as an argument to a constructor of the type of the enum is UB. Changing to the underlying type of the enum would solve the UB Differential Revision: https://reviews.llvm.org/D50909 llvm-svn: 340200
2017-11-08Target/TargetInstrInfo.h -> CodeGen/TargetInstrInfo.h to match layeringDavid Blaikie1-1/+1
This header includes CodeGen headers, and is not, itself, included by any Target headers, so move it into CodeGen to match the layering of its implementation. llvm-svn: 317647
2017-09-14Add AddresSpace to PseudoSourceValue.Jan Sjodin1-17/+28

2017-03-28Fix crashing on TargetCustom PseudoSourceValuesMatt Arsenault1-1/+4
Default to something more reasonable if printCustom isn't implemented. llvm-svn: 298941
2016-04-18[NFC] Header cleanupMehdi Amini1-4/+1
Removed some unused headers, replaced some headers with forward class declarations. Found using simple scripts like this one: clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap' Patch by Eugene Kosov <claprix@yandex.ru> Differential Revision: http://reviews.llvm.org/D19219 From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 266595

2015-08-11PseudoSourceValue: Transform the mips subclass to target independent subclassesAlex Lorenz1-1/+42
This commit transforms the mips-specific 'MipsCallEntry' subclass of the 'PseudoSourceValue' class into two, target-independent subclasses named 'GlobalValuePseudoSourceValue' and 'ExternalSymbolPseudoSourceValue'. This change makes it easier to serialize the pseudo source values by removing target-specific pseudo source values. Reviewers: Akira Hatanaka llvm-svn: 244698
2015-08-11PseudoSourceValue: Replace global manager with a manager in a machine function.Alex Lorenz1-47/+27
This commit removes the global manager variable which is responsible for storing and allocating pseudo source values and instead it introduces a new manager class named 'PseudoSourceValueManager'. Machine functions now own an instance of the pseudo source value manager class. This commit also modifies the 'get...' methods in the 'MachinePointerInfo' class to construct pseudo source values using the instance of the pseudo source value manager object from the machine function. This commit updates calls to the 'get...' methods from the 'MachinePointerInfo' class in a lot of different files because those calls now need to pass in a reference to a machine function to those methods. This change will make it easier to serialize pseudo source values as it will enable me to transform the mips specific MipsCallEntry PseudoSourceValue subclass into two target independent subclasses. Reviewers: Akira Hatanaka llvm-svn: 244693
2015-08-11PseudoSourceValue: Introduce a 'PSVKind' enumerator.Alex Lorenz1-17/+19
This commit introduces a new enumerator named 'PSVKind' in the 'PseudoSourceValue' class. This enumerator is now used to distinguish between the various kinds of pseudo source values. This change is done in preparation for the changes to the pseudo source value object management and to the PseudoSourceValue's class hierarchy - the next two PseudoSourceValue commits will get rid of the global variable that manages the pseudo source values and the mips specific MipsCallEntry subclass. Reviewers: Akira Hatanaka llvm-svn: 244687
2015-08-11PseudoSourceValue: Update comments and fix lowercase variable names. NFC.Alex Lorenz1-1/+1
This commit updates the documentation comments in PseudoSourceValue.cpp and PseudoSourceValue.h based on the LLVM's documentation style. It also fixes several instances of variable names that started with a lowercase letter. This change is done in preparation for the changes to the pseudo source value object management and to the PseudoSourceValue's class hierarchy. llvm-svn: 244686
2015-08-11Reformat PseudoSourceValue.cpp and PseudoSourceValue.h. NFC.Alex Lorenz1-29/+26
This commit reformats the files lib/CodeGen/PseudoSourceValue.cpp and include/llvm/CodeGen/PseudoSourceValue.h using clang-format. This change is done in preparation for the changes to the pseudo source value object management and to the PseudoSourceValue's class hierarchy. llvm-svn: 244685
2014-08-16Make isAliased property for fixed-offset stack objects adjustableHal Finkel1-6/+2
We used to assume that any fixed-offset stack object was not aliased. This meant that no IR value could point to the memory contained in such an object. This is a reasonable default, but is not a universally-correct target-independent fact. For example, on PowerPC (both Darwin and non-Darwin), some byval arguments are allocated at fixed offsets by the ABI. These, however, certainly can be pointed to by IR values. This change moves the 'isAliased' logic out of FixedStackPseudoSourceValue and into MFI, and allows the isAliased property to be overridden for fixed-offset objects. This will be used by an upcoming commit to the PowerPC backend to fix PR20280. No functionality change intended (the behavior of FixedStackPseudoSourceValue::isAliased has been made more conservative for callers that don't pass an MFI object, but I don't see any in-tree callers that do that). llvm-svn: 215794
2014-04-15Break PseudoSourceValue out of the Value hierarchy. It is now the root of ↵Nick Lewycky1-7/+3
its own tree containing FixedStackPseudoSourceValue (which you can use isa/dyn_cast on) and MipsCallEntry (which you can't). Anything that needs to use either a PseudoSourceValue* and Value* is strongly encouraged to use a MachinePointerInfo instead. llvm-svn: 206255
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth1-2/+2
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. llvm-svn: 171366
2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth1-2/+2
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131

stack slots and giving them different PseudoSourceValue's did not fix the problem of post-alloc scheduling miscompiling llvm itself. - Apply Dan's conservative workaround by assuming any non fixed stack slots can alias other memory locations.

2009-09-23Give MachineMemOperand an operator<<, factoring out code fromDan Gohman1-7/+3
two different places for printing MachineMemOperands. Drop the virtual from Value::dump and instead give Value a protected virtual hook that can be overridden by subclasses to implement custom printing. This lets printing be more consistent, and simplifies printing of PseudoSourceValue values. llvm-svn: 82599

This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). llvm-svn: 75640
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin1-1/+2
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. llvm-svn: 75379
