* [lldb] Adapt for NetBSD-9.99.30 ptrace(2) API changesKamil Rytarowski2019-12-242-2/+21
| | | | | | | | Switch from PT_LWPINFO to PT_LWPSTATUS/PT_LWPNEXT. Keep compat support for < 9.99.30. No functional change intended.
* [compiler-rt] Adapt for ptrace(2) changes in NetBSD-9.99.30Kamil Rytarowski2019-12-245-3/+64

* [X86] Use 128-bit vector instructions for f32/f64->i64 conversions on 32-bit ↵Craig Topper2019-12-242-23/+22
| | | | | | | | | | | | | | targets with avx512dq and avx512vl instructions. On 32-bit targets we can't use the scalar instruction so we insert the scalar into a vector and use packed conversions. Previously we used either v4f32->v4i64 or v4f64->v4i64 to avoid some complexity creating target specific ISD opcodes for v4f32->v2i64. But this causes extra vzeroupper instructions and possibly frequency throttling on Intel CPUs. This patch changes this to create a 128-bit vector and uses a target specific ISD opcode if needed.

| | | | | | | | | class m_scratch_ast_source_up is only used by ClangASTContextForExpressions so it should also be declared only in that class. Also make all other members of ClangASTContext private and move the initialization code for ClangASTContextForExpressions into the constructor.

* [lldb][NFC] Remove ClangExternalASTSourceCommonRaphael Isemann2019-12-249-142/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | ClangExternalASTSourceCommon's purpose is to store a map from Decl*/Type* to ClangASTMetadata. Usually this data is accessed via the ClangASTContext interface which then grabs the current ExternalASTSource of its ASTContext, tries to cast it to ClangExternalASTSourceCommon and then accesses the metadata map. If the casting fails the setter does nothing and the getter returns a nullptr as if there was no known metadata for a type/decl. This system breaks as soon as any non-LLDB ExternalASTSource is added via a multiplexer to our existing ExternalASTSource (in which case we suddenly loose all out metadata as the casting always fails with an ExternalASTSource that is not inheriting from ClangExternalASTSourceCommon). This patch moves the metadata map to the ClangASTContext. This gets rid of all the fragile casting, the requirement that every ExternalASTSource in LLDB has to inherit from ClangExternalASTSourceCommon and simplifies the metadata implementation to a simple map lookup. As ClangExternalASTSourceCommon had no other purpose than storing metadata, this patch deletes this class and replaces all uses with clang::ExternalASTSource. No other code changes in this commit beside the AppleObjCDeclVendor which was the only code that did not use the ClangASTContext interface but directly accessed the ClangExternalASTSourceCommon.

* Revert "[Support] Extend TimeProfiler to support multiple threads"Russell Gallop2019-12-242-86/+18
| | | | | | | and "[Support] Try to fix bot failure after 8ddcd1dc26" This reverts commits f70f180148 and 8ddcd1dc26 as this was breaking the MacOS build, which doesn't support thread_local.
* [clang] [ast] CXXRecordDecl::getVisibleConversionFunctions() could be constWhisperity2019-12-242-13/+12
| | | | | | | | | | The function and its called static helpers don't modify the received CXXRecordDecl arguments at all as the method's result is put into an output parameter. Thus they can be const which allows for neatly grabbing the conversion methods in a context where we only have a const ASTUnit at hand. Differential Revision: https://reviews.llvm.org/D71805
* [TypePromotion] Make TypeSize a class memberSam Parker2019-12-241-87/+98
| | | | | | | | | Having TypeSize as a static class variable was causing problems with multi-threading. Several static functions have now been converted into methods of TypePromotion and a few other members of TypePromotion and IRPromoter have been added or removed.

* [llvm-readobj] - Remove an excessive helper for printing dynamic tags.Georgii Rymar2019-12-243-147/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the `getTypeString` from readeobj source because it almost duplicates the existent method: `ELFFile<ELFT>::getDynamicTagAsString`. Side effect: now it prints "<unknown:>0xHEXVALUE" instead of "(unknown)" for unknown values. llvm-readelf before this patch printed: ``` 0x0000000012345678 (unknown) 0x8765432187654321 0x000000006abcdef0 (unknown) 0x9988776655443322 0x0000000076543210 (unknown) 0x5555666677778888 ``` and now it prints: ``` 0x0000000012345678 (<unknown:>0x12345678) 0x8765432187654321 0x000000006abcdef0 (<unknown:>0x6abcdef0) 0x9988776655443322 0x0000000076543210 (<unknown:>0x76543210) 0x5555666677778888 ``` GNU reaedlf prints different thing: ``` 0x0000000012345678 (<unknown>: 12345678) 0x8765432187654321 0x000000006abcdef0 (Operating System specific: 6abcdef0) 0x9988776655443322 0x0000000076543210 (Processor Specific: 76543210) 0x5555666677778888 ``` I am not sure we want to follow GNU here. Even if we do, it should be separate patch probably. The new output looks better and closer to GNU anyways, and the code is a bit simpler. Differential revision: https://reviews.llvm.org/D71835

* test: correct flags for WindowsSaleem Abdulrasool2019-12-231-0/+2

* NFC: Rename printOptionValue to printValue to fix MSVC build.River Riddle2019-12-231-9/+7
| | | | MSVC has trouble resolving the static 'printOptionValue' from the method on llvm::cl::opt/list. This change renames the static method to avoid this conflict.
* DebugInfo: Support dumping any exprloc as an expressionDavid Blaikie2019-12-232-1/+103
| | | | | | | Now that DWARFv5 provides a way to identify DWARF expressions based on form, rather than only by attribute - use it to always provide pretty printing for any exprloc attribute, not only the attributes known to contain expressions.

| | | | | | | | | | | | | | | | These bindings were added as an experiment, and never had a CMake configuration. We will bring back python bindings after picking carefully our dependency and the kind of layering we expect to expose for these bindings. PiperOrigin-RevId: 286963717
| * Refactor the way that pass options are specified.River Riddle2019-12-2310-177/+369
| | | | | | | | | | | | | | | | | | This change refactors pass options to be more similar to how statistics are modeled. More specifically, the options are specified directly on the pass instead of in a separate options class. (Note that the behavior and specification for pass pipelines remains the same.) This brings about several benefits: * The specification of options is much simpler * The round-trip format of a pass can be generated automatically * This gives a somewhat deeper integration with "configuring" a pass, which we could potentially expose to users in the future.

| * NFC: Replace ValuePtr with Value and remove it now that Value is value-typed.River Riddle2019-12-23192-2271/+2160
| | | | | | | | | | | | ValuePtr was a temporary typedef during the transition to a value-typed Value. PiperOrigin-RevId: 286945714
| * Change the `notifyRootUpdated` API to be transaction based.River Riddle2019-12-2310-87/+199
| | | | | | | | | | | | This means that in-place, or root, updates need to use explicit calls to `startRootUpdate`, `finalizeRootUpdate`, and `cancelRootUpdate`. The major benefit of this change is that it enables in-place updates in DialectConversion, which simplifies the FuncOp pattern for example. The major downside to this is that the cases that *may* modify an operation in-place will need an explicit cancel on the failure branches(assuming that they started an update before attempting the transformation).
