* Add "operator bool" to SB APIsPavel Labath2019-03-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Summary: Our python version of the SB API has (the python equivalent of) operator bool, but the C++ version doesn't. This is because our python operators are added by modify-python-lldb.py, which performs postprocessing on the swig-generated interface files. In this patch, I add the "operator bool" to all SB classes which have an IsValid method (which is the same logic used by modify-python-lldb.py). This way, we make the two interfaces more constent, and it allows us to rely on swig's automatic syntesis of python __nonzero__ methods instead of doing manual fixups.

* [SBAPI] Log from record macroJonas Devlieghere2019-03-071-39/+0
| | | | | | | | | | | | | | | | The current record macros already log the function being called. This patch extends the macros to also log their input arguments and removes explicit logging from the SB API. This might degrade the amount of information in some cases (because of smarter casts or efforts to log return values). However I think this is outweighed by the increased coverage and consistency. Furthermore, using the reproducer infrastructure, diagnosing bugs in the API layer should become much easier compared to relying on log messages.

* Replace 'ap' with 'up' suffix in variable names. (NFC)Jonas Devlieghere2019-02-131-2/+2
| | | | | | | | | | | | | | | | | The `ap` suffix is a remnant of lldb's former use of auto pointers, before they got deprecated. Although all their uses were replaced by unique pointers, some variables still carried the suffix. In r353795 I removed another auto_ptr remnant, namely redundant calls to ::get for unique_pointers. Jim justly noted that this is a good opportunity to clean up the variable names as well. I went over all the changes to ensure my find-and-replace didn't have any undesired side-effects. I hope I didn't miss any, but if you end up at this commit doing a git blame on a weirdly named variable, please know that the change was unintentional. llvm-svn: 353912
* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* [SymbolFile] Remove SymbolContext parameter from FindTypes.Zachary Turner2019-01-141-2/+1
| | | | | | | | | | | | | | This parameter was only ever used with the Module set, and since a SymbolFile is tied to a module, the parameter turns out to be entirely unnecessary. Furthermore, it doesn't make a lot of sense to ask a caller to ask SymbolFile which is tied to Module X to find types for Module Y, but that possibility was open with the previous interface. By removing this parameter from the API, it makes it harder to use incorrectly as well as easier for an implementor to understand what it needs to do. llvm-svn: 351133
* Rename ObjectFile::GetHeaderAddress to GetBaseAddressPavel Labath2018-12-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Summary: This function was named such because in the case of MachO files, the mach header is located at this address. However all (most?) usages of this function were not interested in that fact, but the fact that this address is used as the base address for expressing various relative addresses in the object file. For other object file formats, this name is not appropriate (and it's probably the reason why this function was not implemented in these classes). In the ELF case the ELF header will usually end up at this address, but this is a result of the linker optimizing the file layout and not a requirement of the spec. For COFF files, I believe the is no header located at this address either.

* [Target] Do not skip a stop on a breakpoint if a plan was completedAleksandr Urakov2018-11-301-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch fixes the next situation. On Windows clang-cl makes no stub before the main function, so the main function is located exactly on module entry point. May be it is the same on other platforms. So consider the following sequence: - set a breakpoint on main and stop there; - try to evaluate expression, which requires a code execution on the debuggee side. Such an execution always returns to the module entry, and the plan waits for it there; - the plan understands that it is complete now and removes its breakpoint. But the breakpoint site is still there, because we also have a breakpoint on entry; - StopInfo analyzes a situation. It sees that we have stopped on the breakpoint site, and it sees that the breakpoint site has owners, and no one logical breakpoint is internal (because the plan is already completed and it have removed its breakpoint); - StopInfo thinks that it's a user breakpoint and skips it to avoid recursive computations; - the program continues. So in this situation the program continues without a stop right after the expression evaluation. To avoid this an additional check that the plan was completed was added.

* Don't type-erase the FunctionNameType or TypeClass enums.Zachary Turner2018-10-251-10/+13

* Don't type-erase the SymbolContextItem enumeration.Zachary Turner2018-10-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When we get the `resolve_scope` parameter from the SB API, it's a `uint32_t`. We then pass it through all of LLDB this way, as a uint32. This is unfortunate, because it means the user of an API never actually knows what they're dealing with. We can call it something like `resolve_scope` and have comments saying "this is a value from the `SymbolContextItem` enumeration, but it makes more sense to just have it actually *be* the correct type in the actual C++ type system to begin with. This way the person reading the code just knows what it is. The reason to use integers instead of enumerations for flags is because when you do bitwise operations on enumerations they get promoted to integers, so it makes it tedious to constantly be casting them back to the enumeration types, so I've introduced a macro to make this happen magically. By writing LLDB_MARK_AS_BITMASK_ENUM after defining an enumeration, it will define overloaded operators so that the returned type will be the original enum. This should address all the mechanical issues surrounding using rich enum types directly. This way, we get a better debugger experience, and new users to the codebase can get more easily acquainted with the codebase because their IDE features can help them understand what the types mean.

* Rename Error -> Status.Zachary Turner2017-05-121-2/+2
| | | | | | | | | | | | | | | This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

ConstString Error RegularExpression Stream StreamString The goal here is to get lldbUtility into a state where it has no dependendencies except on itself and LLVM, so it can be the starting point at which to start untangling LLDB's dependencies. These are all low level and very widely used classes, and previously lldbUtility had dependencies up to lldbCore in order to use these classes. So moving then down to lldbUtility makes sense from both the short term and long term perspective in solving this problem. Differential Revision: https://reviews.llvm.org/D29427 llvm-svn: 293941
* *** This commit represents a complete reformatting of the LLDB source codeKate Stone2016-09-061-631/+469
| | | | | | | | | | | | | | | | | | | | | | | *** to conform to clang-format’s LLVM style. This kind of mass change has *** two obvious implications: Firstly, merging this particular commit into a downstream fork may be a huge effort. Alternatively, it may be worth merging all changes up to this commit, performing the same reformatting operation locally, and then discarding the merge for this particular commit. The commands used to accomplish this reformatting were as follows (with current working directory as the root of the repository): find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} + find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ; The version of clang-format used was 3.9.0, and autopep8 was 1.2.4. Secondly, “blame” style tools will generally point to this commit instead of a meaningful prior commit. There are alternatives available that will attempt to look through this change and find the appropriate prior commit. YMMV. llvm-svn: 280751
* Now that SymbolFileDWARF supports having types in completely separate .pcm ↵Greg Clayton2016-02-101-0/+3
| | | | | | | | | | | | | | file with "-fmodules -gmodules", each SymbolFileDWARF can reference module DWARF info by looking in other DWARF files. Then if you have 1000 .o files that each reference one or more .pcm files in their debug info, a simple Module::FindTypes(...) call can end up searching the same .pcm file over and over and over. Now all internal FindTypes methods in classes (ModuleList, Module, SymbolFile) now take an extra argument: llvm::DenseSet<lldb_private::SymbolFile *> &searched_symbol_files Each time a SymbolFile::FindTypes() is called, it needs to check the searched_symbol_files list to make sure it hasn't already been asked to find the type and return immediately if it has been checked. This will stop circular dependencies from also crashing LLDB during type queries. This has proven to be an issue when debugging large applications on MacOSX that use DWARF in .o files. <rdar://problem/24581488> llvm-svn: 260434

* Fixed SBModule::GetUUIDString() to not use a static character buffer.Greg Clayton2015-02-111-21/+15
| | | | | | Rules for returning "const char *" from functions in the public lldb::SB* API are that you must constify the string using "ConstString(cstr).GetCString()" and return that. This puts the string into a string pool that never goes away. This is only when there is nothing that can hold onto the string. It is OK to specify that a string value lives as long as its SB class counterpart, but this should be made clear in the API if this is done. Many classes already constify their strings (symbol mangled and demangled names, variable names, type names, etc), so be sure to verify you string isn't already constified before you re-constify it. It won't do any harm to re-constify it, it will just cause you a little performance by having to rehash the string. llvm-svn: 228867

* Huge change to clean up types.Greg Clayton2013-07-111-3/+3

There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.

* Added a way to extract the module specifications from a file. A module ↵Greg Clayton2013-07-081-0/+14

A list of module specifications can be used to enumerate objects in container objects (like universal mach files and BSD archive files).

| | | | | | | | LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down. All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down. llvm-svn: 178191

| | | | | | | | | | Fix in loading mach files from memory when using DynamicLoaderMacOSXDYLD. Removed the uuid mismatch warning that could be spit out and any time during debugging and removed the test case that was looking for that. Currently the "add-dsym" or "target symbols add" command will report an error when the UUID's don't match. Be more careful when checking and resolving section + offset addresses to make sure none of the base addresses are invalid. llvm-svn: 174222

| | | | | | | | | | | | Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. llvm-svn: 162860

| | | | | | | | | | Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not). This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method. This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB. llvm-svn: 153482

| | | | | | | | | | | | | | | | | | | | | | | | | I started work on being able to add symbol files after a debug session had started with a new "target symfile add" command and quickly ran into problems with stale Address objects in breakpoint locations that had lldb_private::Section pointers into modules that had been removed or replaced. This also let to grabbing stale modules from those sections. So I needed to thread harded the Address, Section and related objects. To do this I modified the ModuleChild class to now require a ModuleSP on initialization so that a weak reference can created. I also changed all places that were handing out "Section *" to have them hand out SectionSP. All ObjectFile, SymbolFile and SymbolVendors were inheriting from ModuleChild so all of the find plug-in, static creation function and constructors now require ModuleSP references instead of Module *. Address objects now have weak references to their sections which can safely go stale when a module gets destructed. This checkin doesn't complete the "target symfile add" command, but it does get us a lot clioser to being able to do such things without a high risk of crashing or memory corruption. llvm-svn: 151336

| | | | | | | | | | | | | | | | Tracking modules down when you have a UUID and a path has been improved. DynamicLoaderDarwinKernel no longer parses mach-o load commands and it now uses the memory based modules now that we can load modules from memory. Added a target setting named "target.exec-search-paths" which can be used to supply a list of directories to use when trying to look for executables. This allows one or more directories to be used when searching for modules that may not exist in the SDK/PDK. The target automatically adds the directory for the main executable to this list so this should help us in tracking down shared libraries and other binaries. llvm-svn: 150426
