* [lldb/SWIG] Fix capitalization for case sensitive file systems.Jonas Devlieghere2020-01-091-4/+4
| | | | | When moving the Python directory I renamed it to python (lowercase) but didn't update the python.swig file.
* [lldb/Bindings] Move bindings into their own subdirectoryJonas Devlieghere2020-01-0980-18/+17
| | | | | | | | | | | | All the code required to generate the language bindings for Python and Lua lives under scripts, even though the majority of this code aren't scripts at all, and surrounded by scripts that are totally unrelated. I've reorganized these files and moved everything related to the language bindings into a new top-level directory named bindings. This makes the corresponding files self contained and much more discoverable. Differential revision: https://reviews.llvm.org/D72437
* [lldb/Lua] Make lldb.debugger et al available to LuaJonas Devlieghere2020-01-0910-3/+89
| | | | | | | | The Python script interpreter makes the current debugger, target, process, thread and frame available to interactive scripting sessions through convenience variables. This patch does the same for Lua. Differential revision: https://reviews.llvm.org/D71801
* [lldb/SWIG] Add missing '\' in macros againJonas Devlieghere2020-01-091-2/+2
| | | | | | Making the string conversion operator a macro unintentionally dropped the backslash before '\n' and '\r' and was therefore incorrectly stripping 'n' and 'r' from the object description.
* [lldb] Modernize OptionValue::SetValueChangedCallbackPavel Labath2020-01-0910-132/+70
| | | | | instead of a function pointer + void*, take a std::function. This removes a bunch of repetitive, unsafe void* casts.
* [lldb/DWARF] Fix mixed v4+v5 location listsPavel Labath2020-01-0910-75/+184
| | | | | | | | | | | | | | | | | | | | | | Summary: Our code was expecting that a single (symbol) file contains only one kind of location lists. This is not correct (on non-apple platforms, at least) as a file can compile units with different dwarf versions. This patch moves the deteremination of location list flavour down to the compile unit level, fixing this problem. I have also tried to rougly align the code with the llvm DWARFUnit. Fully matching the API is not possible because of how lldb's DWARFExpression lives separately from the rest of the DWARF code, but this is at least a step in the right direction.

* [lldb/DWARF] Add is_dwo member to DWARFUnitPavel Labath2020-01-097-20/+19
| | | | | | | | | | | | | | | | | | | | | | Summary: A skeleton unit can easily be detected by checking the m_dwo_symbol_file member, but we cannot tell a split unit from a normal unit from the "inside", which is sometimes useful. This patch adds a m_is_dwo member to enable this, and align the code with llvm::DWARFUnit. Right now it's only used to avoid creating a split unit inside another split unit (which removes one override from SymbolFileDWARFDwo and brings us a step closer to deleting it), but my main motivation is fixing the handling of location lists in mixed v4&v5 files. This comes in a separate patch. Reviewers: JDevlieghere, aprantl, clayborg Subscribers: dblaikie, lldb-commits Tags: #lldb Differential Revision: https://reviews.llvm.org/D71750
* [lldb] Fix that TestNoSuchArch.py was passing for the wrong reasonRaphael Isemann2020-01-091-2/+2
| | | | | | The command here failed due to the type in 'create' but the expect did not actually check for the error message. This fixes the typo and adds a check for the actuall error message we should see.
* [lldb/SWIG] Refactor extensions to be non Python-specific (3/3)Jonas Devlieghere2020-01-0818-253/+59
| | | | | | | | | | | The current SWIG extensions for the string conversion operator is Python specific because it uses the PythonObjects. This means that the code cannot be reused for other SWIG supported languages such as Lua. This reimplements the extensions in a more generic way that can be reused. It uses a SWIG macro to reduce code duplication. Differential revision: https://reviews.llvm.org/D72377
* Save more descriptive error msg from FBS/BKS, relay it up to lldb.Jason Molenda2020-01-081-20/+26
| | | | | | | | | | | | | | | | | | | When lldb requests an app launch through FrontBoard/BackBoard, we get back an NSError object if there was a problem with an integer error code and a descriptive text string. debugserver would log the descriptive text string to the console, but it would only save the error code value, ask for the much-less-specific name of that error code, and send that very generic error word back to lldb. This patch saves the longer description of the failure when available, and sends that to lldb. If unavailable, it falls back to sending up the generic description of the error code as it was doing before. This only impacts the iOS on-device debugserver. <rdar://problem/49953304>

* [lldb] Remove default llvm::Triple argument from ClangASTContext constructorRaphael Isemann2020-01-082-3/+4
| | | | | | | | | | | Creating an ASTContext with an unknown triple is rarely a good idea (as usually all our ASTs have a valid triple that is either from the host or the target) and the default argument makes it far to easy to implicitly create such an AST. Let's remove it and force people to pass a triple. The only place where we don't pass a triple is a DWARFASTParserClangTests where we now just pass the host triple instead (the test doesn't depend on any triple so this shouldn't change anything).
* [lldb][NFC] Remove redundant ClangASTContext constructor that takes ArchSpecRaphael Isemann2020-01-082-30/+23
| | | | | | | ArchSpec has a superset of the information of llvm::Triple but the ClangASTContext just uses the Triple part of it. This deletes the ArchSpec constructor and all the code creating ArchSpecs and instead just uses the llvm::Triple constructor for ClangASTContext.
* [lldb/CMake] Only auto-enable Python when SWIG is foundJonas Devlieghere2020-01-072-36/+37
| | | | | | | | | As correctly pointed out by Martin on the mailing list, Python should only be auto-enabled if SWIG is found as well. This moves the logic of finding SWIG into FindPythonInterpAndLibs to make that possible. To make diagnosing easier I've included a status message to convey why Python support is disabled.
* [lldb/Test] Try to appease the Windows botJonas Devlieghere2020-01-071-1/+0
| | | | | | | | | | | | In TestConvenienceVariables I changed %t from a file to a directory. This tripped up mkdir which can't deal with an existing file at the given location. In order to solve this issue on the bots I added an `rm -rf %t` statement, but now the Windows bot complains that "This function is not supported on this system". If you never ran the test suite wit this temporary workaround, the test might fail. If this happens please remove what %t expands to in the lit output and rerun the test.
* Revert "Re-land "[lldb/Lua] Add string conversion operator for SBTarget.""Jonas Devlieghere2020-01-074-12/+12
| | | | | | This was returning a pointer to a stack-allocated memory location. This works for Python where we return a PythonString which must own the underlying string.

* [lldb/Test] Make TestConvenienceVariables more strictJonas Devlieghere2020-01-071-14/+11
| | | | | | This test was passing even when the output of lldb.target was empty. I've made the test more strict by checking explicitly for the target name and by using CHECK-NEXT lines.

* [lldb][NFC] Use static_cast instead of reinterpret_cast where possibleRaphael Isemann2020-01-0716-69/+67
| | | | | | | | | | | | | | Summary: There are a few places in LLDB where we do a `reinterpret_cast` for conversions that we could also do with `static_cast`. This patch moves all this code to `static_cast`.

* [lldb][NFC] Take a llvm::Triple in ClangASTContext constructorRaphael Isemann2020-01-077-18/+13
| | | | | | This constructor is supposed to take a string representing an llvm::Triple. We might as well take a llvm::Triple here which saves us all the string conversions in the call sites and we make this more type safe.
* [lldb] Fix LLDB build after API change to printInst (D72172)Raphael Isemann2020-01-071-2/+2

* Change the patterns to include the prefix '= ' so we don't pass errantly.Jason Molenda2020-01-061-5/+5
