* [lldb] Update hardcoded Makefile.rules inclusions.Jordan Rupprecht2019-12-051-2/+1
| | | | | | This replaces `include $(LEVEL)/Makefile.rules` with `include Makefile.rules`. The lldb test driver already passes the include path when running make, and specifically looking for "../../Makefile.rules" forces the test to be in a specific location. Removing this hardcoded relative path will make it possible to move this test as-is.

| | | | | | | | | I have either opened new bug reports for these tests, or added links to existing bugs. This should help make the lldb-aarch64-ubuntu buildbot green (there will still be some unexpected passes that someone should look into, but those can be handled later).
* Complete complete types early when importing types from Clang module DWARF.Adrian Prantl2019-11-226-0/+95
| | | | | | | | | | | | | | | | | | | | | This affects -gmodules only. Under normal operation pcm_type is a shallow forward declaration that gets completed later. This is necessary to support cyclic data structures. If, however, pcm_type is already complete (for example, because it was loaded for a different target before), the definition needs to be imported right away, too. Type::ResolveClangType() effectively ignores the ResolveState inside type_sp and only looks at IsDefined(), so it never calls ClangASTImporter::ASTImporterDelegate::ImportDefinitionTo(), which does extra work for Objective-C classes. This would result in only the forward declaration to be visible. An alternative implementation would be to sink this into Type::ResolveClangType ( https://github.com/llvm/llvm-project/blob/88235812a71d99c082e7aa2ef9356d43d1f83a80/lldb/source/Symbol/Type.cpp#L5809) though it isn't clear to me how to best do this from a layering perspective. rdar://problem/52134074 Differential Revision: https://reviews.llvm.org/D70415

* Speed up accelerator table lookupsAdrian Prantl2019-10-1011-0/+92
| | | | | | | | | | | | | | | | | | | When debugging a large program like clang and doing "frame variable *this", the ValueObject pretty printer is doing hundreds of scoped FindTypes lookups. The ones that take longest are the ones where the DWARFDeclContext ends in something like ::Iterator which produces many false positives that need to be filtered out *after* extracting the DIEs. This patch demonstrates a way to filter out false positives at the accerator table lookup step. With this patch lldb clang-10 -o "b EmitFunctionStart" -o r -o "f 2" -o "fr v *this" -b -- ... goes (in user time) from 5.6s -> 4.8s or (in wall clock) from 6.9s -> 6.0s.

* Add test coverage to printing of enums and fix display of unsigned valuesFrederic Riss2019-10-082-29/+57
| | | | | | | | | | | | | | | TestCPP11EnumTypes.py should have covered all our bases when it comes to typed enums, but it missed the regression introduced in r374066. The reason it didn't catch it is somewhat funny: the test was copied over from another test that recompiled a source file with a different base type every time, but neither the test source nor the python code was adapted for testing enums. As a result, this test was just running 8 times the exact same checks on the exact same binary. This commit fixes the coverage and addresses the issue revealed by the new tests. llvm-svn: 374108
* [Testsuite] Get rid of most of the recursive shared library MakefilesFrederic Riss2019-10-086-49/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the secondary Makefiles we have are just a couple variable definitions and then an include of Makefile.rules. This patch removes most of the secondary Makefiles and replaces them with a direct invocation of Makefile.rules in the main Makefile. The specificities of each sub-build are listed right there on the recursive $(MAKE) call. All the variables that matter are being passed automagically by make as they have been passed on the command line. The only things you need to specify are the variables customizating the Makefile.rules logic for each image. This patch also removes most of the clean logic from those Makefiles and from Makefile.rules. The clean rule is not required anymore now that we run the testsuite in a separate build directory that is wiped with each run. The patch leaves a very crude version of clean in Makefile.rules which removes everything inside of $(BUILDDIR). It does this only when the $(BUILDDIR) looks like a sub-directory of our standard testsuite build directory to be extra safe.

* Add pretty printing of Clang "bitfield" enumsFrederic Riss2019-10-082-3/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Using enumerators as flags is standard practice. This patch adds support to LLDB to display such enum values symbolically, eg: (E) e1 = A | B If enumerators don't cover the whole value, the remaining bits are displayed as hexadecimal: (E) e4 = A | 0x10 Detecting whether an enum is used as a bitfield or not is complicated. This patch implements a heuristic that assumes that such enumerators will either have only 1 bit set or will be a combination of previous values. This patch doesn't change the way we currently display enums which the above heuristic would not consider as bitfields.

* [lldb] Print better diagnostics for user expressions and modulesRaphael Isemann2019-09-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Currently our expression evaluators only prints very basic errors that are not very useful when writing complex expressions. For example, in the expression below the user made a type error, but it's not clear from the diagnostic what went wrong: ``` (lldb) expr printf("Modulos are:", foobar%mo1, foobar%mo2, foobar%mo3) error: invalid operands to binary expression ('int' and 'double') ``` This patch enables full Clang diagnostics in our expression evaluator. After this patch the diagnostics for the expression look like this: ``` (lldb) expr printf("Modulos are:", foobar%mo1, foobar%mo2, foobar%mo3) error: <user expression 1>:1:54: invalid operands to binary expression ('int' and 'float') printf("Modulos are:", foobar%mo1, foobar%mo2, foobar%mo3) ~~~~~~^~~~ ``` To make this possible, we now emulate a user expression file within our diagnostics. This prevents that the user is exposed to our internal wrapper code we inject. Note that the diagnostics that refer to declarations from the debug information (e.g. 'note' diagnostics pointing to a called function) will not be improved by this as they don't have any source locations associated with them, so caret or line printing isn't possible. We instead just suppress these diagnostics as we already do with warnings as they would otherwise just be a context message without any context (and the original diagnostic in the user expression should be enough to explain the issue).

* Clean up this test.Jim Ingham2019-09-181-46/+11
| | | | | | | | | | | | | I don't know what the intent of parts of this test were. We set a bunch of breakpoints and ran from one to the other, doing "self.runCmd("thread backtrace")" then continuing to the next one. We didn't actually verify the contents of the backtrace, nor that we hit the breakpoints we set in any particular order. The only actual test was to run sel_getName at two of these stops. So I reduced the test to just stopping at the places where we were actually going to run an expression, and tested the expression. llvm-svn: 372196

* [lldb] Fix dynamic_cast by no longer failing on variable without metadataRaphael Isemann2019-08-105-0/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Our IR rewriting infrastructure currently fails when it encounters a variable which has no metadata associated. This causes dynamic_cast to fail as in this case IRForTarget considers the type info pointers ('@_ZTI...') to be variables without associated metadata. As there are no variables for these internal variables, this is actually not an error and dynamic_cast would work fine if we didn't throw this error. This patch fixes this by removing this diagnostics code. In case we would actually hit a variable that has no metadata (but is supposed to have), we still have the error in the expression log so this shouldn't make it harder to diagnose any missing metadata errors. This patch should fix dynamic_cast and also adds a bunch of test coverage to that language feature.

* Adjust a ValueObjectChild's offset when the child is a bitfieldAdrian Prantl2019-08-072-0/+11
| | | | | | | | | | | | | | | | | | If a bitfield doesn't fit into the child_byte_size'd window at child_byte_offset, move the window forward until it fits. The problem here is that Value has no notion of bitfields and thus the Value's DataExtractor is sized like the bitfields CompilerType; a sequence of bitfields, however, can be larger than their underlying type. This was not in the big-endian-derived DWARF 2 bitfield attributes because their offsets were counted from the end of the window, so they always fit. rdar://problem/53132189 Differential Revision: https://reviews.llvm.org/D65492 llvm-svn: 368226
* Fix ClangASTContext::CreateParameterDeclaration to not call addDeclShafik Yaghmour2019-08-026-0/+71
| | | | | | | | | Summary: The change https://reviews.llvm.org/D55575 modified ClangASTContext::CreateParameterDeclaration to call decl_ctx->addDecl(decl); this caused a regression since the existing code in DWARFASTParserClang::ParseChildParameters is called with the containing DeclContext. So when end up with cases where we are parsing a parameter for a member function and the parameter is added to the CXXRecordDecl as opposed to the CXXMethodDecl. This example is given in the regression test TestBreakpointInMemberFuncWNonPrimitiveParams.py which without this fix in a modules build leads to assert on setting a breakpoint in a member function with non primitive parameters. This scenario would be common when debugging LLDB or clang. Differential Revision: https://reviews.llvm.org/D65414 llvm-svn: 367726

| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: We assume in LLDB that every type comes from an ASTContext with an associated ClangASTContext. However the types inside the ClangModuleDeclVendor don't have a ClangASTContext so we end up crashing whenever we create a CompilerType for one of these types. Simplest way to trigger this bug is to just look up NSObject from a module: (lldb) expr @import Foundation (lldb) type lookup NSObject Assertion failed: (m_type_system != nullptr), function CompilerType, file /Users/teemperor/llvm1/llvm-project/lldb/source/Symbol/CompilerType.cpp, line 39.

The best solution would be to include that header (or even better, import Clang's builtin module), but header-parsing and (cross-platform) importing modules is not ready yet. Until we get this working with modules I would say we add the macro to our existing macro list as we already do with other macros from stddef.h/stdint.h.

The solution is to use noload_lookup, which works well with transparent contexts. But, we cannot use only the noload_lookup since the slow case of localUncachedLookup is still needed in some other cases. These other cases are handled in ASTImporterLookupTable, but we cannot use that with LLDB since that traverses through the AST which initiates the load of external decls again via DC::decls(). We must avoid loading external decls during the import becuase ExternalASTSource is implemented with ASTImporter, so external loads during import results in uncontrolled and faulty import.
