* [testsuite] xfailed two tests that depend on NSString conforming to NSCopying.Sean Callanan2017-06-141-0/+4
| | | | | | | | | | | | | NSString is loaded from the DWARF, which doesn't have the concept of protocols. When this is used with the NSMutableDictionary type from Objective-C modules, this produces errors of the form error: cannot initialize a parameter of type 'id<NSCopying> _Nonnull' with an rvalue of type 'NSString *' We're aware of these problems and have an internal bug report filed (<rdar://problem/32777981>) llvm-svn: 305424
* [LLDB][MIPS] Fix TestRegisterVariables.py.Nitesh Jain2017-06-141-1/+1
| | | | | | | | | Clang does not accept regparm attribute on these platforms. Fortunately, the default calling convention passes arguments in registers any way Subscribers: jaydeep, bhushan, lldb-commits, slthakur llvm-svn: 305378
* [TypeSystem] Handle Clang AttributedTypesSean Callanan2017-06-021-10/+121
| | | | | | | | | | | | | | | | | | | When parsing types originating in modules, it is possible to encounter AttributedTypes (such as the type generated for NSString *_Nonnull). Some of LLDB's ClangASTContext methods deal with them; others do not. In particular, one function that did not was GetTypeInfo, causing TestObjCNewSyntax to fail. This fixes that, treating AttributedType as essentially transparent and getting the information for the modified type. In addition, however, TestObjCNewSyntax is a monolithic test that verifies a bunch of different things, all of which can break independently of one another. I broke it apart into smaller tests so that we get more precise failures when something (like this) breaks. Differential Revision: https://reviews.llvm.org/D33812 llvm-svn: 304510
* Added a testcase for local/namespaced name conflicts.Sean Callanan2017-05-313-0/+39
| | | | | | | | | This works on SVN but is a bit fragile on the Swift branch. I'm adding the test to both, so we have this path covered. <rdar://problem/32372372> llvm-svn: 304314
* Make TestConflictingSymbol run on non-darwin targetsPavel Labath2017-05-171-7/+11
| | | | | | | | | | | For remote targets we need to call registerSharedLibrariesWithTarget to make sure they are installed alongside main executable. This also required a small fixup in the the mentioned function as in this case "One" was both a directory name and a library name template. I fixed it to make sure it checks that the string refers to a file before it assumed it was a full library path. llvm-svn: 303248
* [Expression parser] Look up module symbols before hunting globallySean Callanan2017-05-1611-0/+161
| | | | | | | | | | | | | | | | | | | When it resolves symbol-only variables, the expression parser currently looks only in the global module list. It should prefer the current module. I've fixed that behavior by making it search the current module first, and only search globally if it finds nothing. I've also added a test case. After review, I moved the core of the lookup algorithm into SymbolContext for use by other code that needs it. Thanks to Greg Clayton and Pavel Labath for their help.

* [TypeSystem] Fix inspection of Objective-C object typesSean Callanan2017-05-153-0/+94
| | | | | | | | | | | | | | ptr_refs exposed a problem in ClangASTContext's implementation: it uses an accessor to downcast a QualType to an ObjCObjectPointerType, but the accessor is not fully general. getAs() is the safer way to go. I've added a test case that uses ptr_refs in a way that would crash before the fix. <rdar://problem/31363513> llvm-svn: 303110

* [DWARF parser] Produce correct template parameter packsSean Callanan2017-05-116-0/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Templates can end in parameter packs, like this template <class T...> struct MyStruct { /*...*/ }; LLDB does not currently support these parameter packs; it does not emit them into the template argument list at all. This causes problems when you specialize, e.g.: template <> struct MyStruct<int> { /*...*/ }; template <> struct MyStruct<int, int> : MyStruct<int> { /*...*/ }; LLDB generates two template specializations, each with no template arguments, and then when they are imported by the ASTImporter into a parser's AST context we get a single specialization that inherits from itself, causing Clang's record layout mechanism to smash its stack. This patch fixes the problem for classes and adds tests. The tests for functions fail because Clang's ASTImporter can't import them at the moment, so I've xfailed that test.

* Windows fix for TestConflictingDefinition makefilePavel Labath2017-05-031-1/+1
| | | | | | | | | | gnuwin32 rm does not like wildcards that match nothing even if we specify -f (probably because the wildcard expansion happens in-process there). We could use make $(wildcard) here, but it seems safer to explicitly list the files here, just like the normal Makefile.rules does. llvm-svn: 302013

* Provide a mechanism to do some pre-loading of symbols up front.Jim Ingham2017-04-281-4/+17
| | | | | | | | | | | Loading a shared library can require a large amount of work; rather than do that serially for each library, this patch will allow parallelization of the symbols and debug info name indexes. From scott.smith@purestorage.com https://reviews.llvm.org/D32598 llvm-svn: 301609

* [Expression parser] Return both types and variablesSean Callanan2017-04-247-2/+98
| | | | | | | | | | | | | | | | | | | | | Many times a user wants to access a type when there's a variable of the same name, or a variable when there's a type of the same name. Depending on the precise context, currently the expression parser can fail to resolve one or the other. This is because ClangExpressionDeclMap has logic to limit the amount of information it searches, and that logic sometimes cuts down the search prematurely. This patch removes some of those early exits. In that sense, this patch trades performance (early exit is faster) for correctness. I've also included two new test cases showing examples of this behavior – as well as modifying an existing test case that gets it wrong. llvm-svn: 301273
* [DWARF] Fix lookup in the abstract origins of inlined blocks/functionsSean Callanan2017-04-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LLDB uses clang::DeclContexts for lookups, and variables get put into the DeclContext for their abstract origin. (The abstract origin is a DWARF pointer that indicates the unique definition of inlined code.) When the expression parser is looking for variables, it locates the DeclContext for the current context. This needs to be done carefully, though, e.g.: __attribute__ ((always_inline)) void f(int a) { { int b = a * 2; } } void g() { f(3); } Here, if we're stopped in the inlined copy of f, we have to find the DeclContext corresponding to the definition of f – its abstract origin. Clang doesn't allow multiple functions with the same name and arguments to exist. It also means that any variables we see must be placed in the appropriate DeclContext. [Bug 1]: When stopped in an inline block, the function GetDeclContextDIEContainingDIE for that block doesn't properly construct a DeclContext for the abstract origin for inlined subroutines. That means we get duplicated function DeclContexts, but function arguments only get put in the abstract origin's DeclContext, and as a result when we try to look for them in nested contexts they aren't found. [Bug 2]: When stopped in an inline block, the DWARF (for space reasons) doesn't explicitly point to the abstract origin for that block. This means that the function GetClangDeclContextForDIE returns a different DeclContext for each place the block is inlined. However, any variables defined in the block have abstract origins, so they will only get placed in the DeclContext for their abstract origin. In this fix, I've introduced a test covering both of these issues, and fixed them. Bug 1 could be resolved simply by making sure we look up the abstract origin for inlined functions when looking up their DeclContexts on behalf of nested blocks. For Bug 2, I've implemented an algorithm that makes the DeclContext for a block be the containing DeclContext for the closest entity we would find during lookup that has an abstract origin pointer. That means that in the following situation: { // block 1 int a; { // block 2 int b; } } if we looked up the DeclContext for block 2, we'd find the block containing the abstract origin of b, and lookup would proceed correctly because we'd see b and a. However, in the situation { // block 1 int a; { // block 2 } } since there isn't anything to look up in block 2, we can't determine its abstract origin (and there is no such pointer in the DWARF for blocks). However, we can walk up the parent chain and find a, and its abstract origin lives in the abstract origin of block 1. So we simply say that the DeclContext for block 2 is the same as the DeclContext for block 1, which contains a. Lookups will return the same results. Thanks to Jim Ingham for review and suggestions.

* Fix TestRegisterVariables for clang/armPavel Labath2017-04-191-2/+11

* Handle UTF-16 and UTF-32 constant CFStringsSean Callanan2016-12-012-0/+11
| | | | | | | | | | | | | | | We have a longstanding issue where the expression parser does not handle wide CFStrings (e.g., @"凸凹") correctly, producing the useless error message Internal error [IRForTarget]: An Objective-C constant string's string initializer is not an array error: warning: expression result unused error: The expression could not be prepared to run in the target This is just a side effect of the fact that we don't handle wide string constants when converting these to CFStringCreateWithBytes. That function takes the string's encoding as an argument, so I made it work and added a testcase. https://reviews.llvm.org/D27291 <rdar://problem/13190557> llvm-svn: 288386
