* Make the FunctionComparator of the MergeFunctions pass a stand-alone utility.Erik Eckstein2016-11-116-1217/+1422
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is pure refactoring. NFC. This change moves the FunctionComparator (together with the GlobalNumberState utility) in to a separate file so that it can be used by other passes. For example, the SwiftMergeFunctions pass in the Swift compiler: https://github.com/apple/swift/blob/master/lib/LLVMPasses/LLVMMergeFunctions.cpp Details of the change: *) The big part is just moving code out of MergeFunctions.cpp into FunctionComparator.h/cpp *) Make FunctionComparator member functions protected (instead of private) so that a derived comparator class can use them. Following refactoring helps to share code between the base FunctionComparator class and a derived class: *) Add a beginCompare() function *) Move some basic function property comparisons into a separate function compareSignature() *) Do the GEP comparison inside cmpOperations() which now has a new needToCmpOperands reference parameter https://reviews.llvm.org/D25385 llvm-svn: 286632

* Bitcode: Clean up error handling for certain bitcode query functions.Peter Collingbourne2016-11-119-361/+315
| | | | | | | | | | | | | The functions getBitcodeTargetTriple(), isBitcodeContainingObjCCategory(), getBitcodeProducerString() and hasGlobalValueSummary() now return errors via their return value rather than via the diagnostic handler. To make this work, re-implement these functions using non-member functions so that they can be used without the LLVMContext required by BitcodeReader.

* [ORC] Refactor the ORC RPC utilities to add some new features.Lang Hames2016-11-1117-1362/+1756
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (1) Add support for function key negotiation. The previous version of the RPC required both sides to maintain the same enumeration for functions in the API. This means that any version skew between the client and server would result in communication failure. With this version of the patch functions (and serializable types) are defined with string names, and the derived function signature strings are used to negotiate the actual function keys (which are used for efficient call serialization). This allows clients to connect to any server that supports a superset of the API (based on the function signatures it supports). (2) Add a callAsync primitive. The callAsync primitive can be used to install a return value handler that will run as soon as the RPC function's return value is sent back from the remote. (3) Launch policies for RPC function handlers. The new addHandler method, which installs handlers for RPC functions, takes two arguments: (1) the handler itself, and (2) an optional "launch policy". When the RPC function is called, the launch policy (if present) is invoked to actually launch the handler. This allows the handler to be spawned on a background thread, or added to a work list. If no launch policy is used, the handler is run on the server thread itself. This should only be used for short-running handlers, or entirely synchronous RPC APIs. (4) Zero cost cross type serialization. You can now define serialization from any type to a different "wire" type. For example, this allows you to call an RPC function that's defined to take a std::string while passing a StringRef argument. If a serializer from StringRef to std::string has been defined for the channel type this will be used to serialize the argument without having to construct a std::string instance. This allows buffer reference types to be used as arguments to RPC calls without requiring a copy of the buffer to be made. llvm-svn: 286620

* [cfi] Implement cfi-icall using inline assembly.Evgeniy Stepanov2016-11-115-99/+252
| | | | | | | | | | | | | | | | | | | | | | | | | The current implementation is emitting a global constant that happens to evaluate to the same bytes + relocation as a jump instruction on X86. This does not work for PIE executables and shared libraries though, because we end up with a wrong relocation type. And it has no chance of working on ARM/AArch64 which use different relocation types for jump instructions (R_ARM_JUMP24) that is never generated for data. This change replaces the constant with module-level inline assembly followed by a hidden declaration of the jump table. Works fine for ARM/AArch64, but has some drawbacks. * Extra symbols are added to the static symbol table, which inflate the size of the unstripped binary a little. Stripped binaries are not affected. This happens because jump table declarations must be external (because their body is in the inline asm). * Original functions that were anonymous are now named <original name>.cfi, and it affects symbolization sometimes. This is necessary because the only user of these functions is the (inline asm) jump table, so they had to be added to @llvm.used, which does not allow unnamed functions. llvm-svn: 286611

* Revert "Use private linkage for MergedGlobals variables" on Darwin.Adrian Prantl2016-11-119-32/+54
| | | | | | | | | | | | | | | | | | | This is a partial revert of r244615 (http://reviews.llvm.org/D11942), which caused a major regression in debug info quality. Turning the artificial __MergedGlobal symbols into private symbols (l__MergedGlobal) means that the linker will not include them in the symbol table of the final executable. Without a symbol table entry dsymutil is not be able to process the debug info for any of the merged globals and thus drops the debug info for all of them. This patch is enabling the old behavior for all MachO targets while leaving all other targets unaffected. rdar://problem/29160481 https://reviews.llvm.org/D26531 llvm-svn: 286607

* Clean up DWARFFormValue by reducing duplicated code and removing ↵Greg Clayton2016-11-117-200/+369
| | | | | | | | | | | | | | | | | | | | | DWARFFormValue::getFixedFormSizes() In preparation for a follow on patch that improves DWARF parsing speed, clean up DWARFFormValue so that we have can get the fixed byte size of a form value given a DWARFUnit or given the version, address byte size and dwarf32/64. This patch cleans up code so that everyone is using one of the new DWARFFormValue functions: static Optional<uint8_t> DWARFFormValue::getFixedByteSize(dwarf::Form Form, const DWARFUnit *U = nullptr); static Optional<uint8_t> DWARFFormValue::getFixedByteSize(dwarf::Form Form, uint16_t Version, uint8_t AddrSize, bool Dwarf32); This patch changes DWARFFormValue::skipValue() to rely on the output of DWARFFormValue::getFixedByteSize(...) instead of duplicating the code in each function. This will reduce the number of changes we need to make to DWARF to fewer places in DWARFFormValue when we add support for new form. This patch also starts to support DWARF64 so that we can get correct byte sizes for forms that vary according the DWARF 32/64. To reduce the code duplication a new FormSizeHelper pure virtual class was created that can be created as a FormSizeHelperDWARFUnit when you have a DWARFUnit, or FormSizeHelperManual where you manually specify the DWARF version, address byte size and DWARF32/DWARF64. There is now a single implementation of a function that gets the fixed byte size (instead of two where one took a DWARFUnit and one took the DWARF version, address byte size and DWARFFormat enum) and one function to skip the form values. https://reviews.llvm.org/D26526 llvm-svn: 286597

* [SystemZ] Use LLGT(R) instructionsUlrich Weigand2016-11-119-46/+260
| | | | | | | | | | | | | This adds support for the 31-to-64-bit zero extension instructions LLGT and LLGTR and uses them for code generation where appropriate. Since this operation can also be performed via RISBG, we have to update SystemZDAGToDAGISel::tryRISBGZero so that we prefer LLGT over RISBG in case both are possible. The patch includes some simplification to the tryRISBGZero code; this is not intended to cause any (further) functional change in codegen. llvm-svn: 286585

| | | | | | | | | | | | | | | | | | | | | Summary: Split ReaderWriter.h which contains the APIs into both the BitReader and BitWriter libraries into BitcodeReader.h and BitcodeWriter.h. This is to address Chandler's concern about sharing the same API header between multiple libraries (BitReader and BitWriter). That concern is why we create a single bitcode library in our downstream build of clang, which led to r286297 being reverted as it added a dependency that created a cycle only when there is a single bitcode library (not two as in upstream).
