2016-09-21Make lldb::Regex use StringRef.Zachary Turner
This updates getters and setters to use StringRef instead of const char *. I tested the build on Linux, Windows, and OSX and saw no build or test failures. I cannot test any BSD or Android variants, however I expect the required changes to be minimal or non-existant. llvm-svn: 282079
2016-09-13Add a few const's (thanks Zachary) and return shared or unique pointersJim Ingham
in places where they help prevent leaks. llvm-svn: 281288
2016-09-12This is the main part of a change to add breakpoint save and restore to lldb.Jim Ingham
Still to come: 1) SB API's 2) Testcases 3) Loose ends: a) serialize Thread options b) serialize Exception resolvers 4) "break list --file" should list breakpoints contained in a file and "break read -f 1 3 5" should then read in only those breakpoints. <rdar://problem/12611863> llvm-svn: 281273
2016-09-06*** This commit represents a complete reformatting of the LLDB source codeKate Stone
*** 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
2016-03-09Add an "offset" option to "break set -n" and "break set -f -l". Jim Ingham
That way you can set offset breakpoints that will move as the function they are contained in moves (which address breakpoints can't do...) I don't align the new address to instruction boundaries yet, so you have to get this right yourself for now. <rdar://problem/13365575> llvm-svn: 263049

2015-03-18Move lldb-log.cpp to core/Logging.cppZachary Turner
So that we don't have to update every single #include in the entire codebase to #include this new header (which used to get included by lldb-private-log.h, we automatically #include "Logging.h" from within "Log.h". llvm-svn: 232653
2014-12-06Add the ability to set breakpoints with conditions, commands, etc,Jim Ingham
in the "dummy-target". The dummy target breakpoints prime all future targets. Breakpoints set before any target is created (e.g. breakpoints in ~/.lldbinit) automatically get set in the dummy target. You can also list, add & delete breakpoints from the dummy target using the "-D" flag, which is supported by most of the breakpoint commands. This removes a long-standing wart in lldb... <rdar://problem/10881487> llvm-svn: 223565
2013-09-27Factor the code that was eliminating redundant breakpoint locations and movingJim Ingham

file & line breakpoint if they are contiguous" to "coalesce the line ranges for a file & line breakpoint to the first range in each block". We were still setting a silly number of independent breakpoints sometimes, and until we get a compiler that emits trustworthy is_stmt flags in the line table, we need to do something to reduce the noise. <rdar://problem/14920404> llvm-svn: 190380

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

Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

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
2012-05-22Also push file & line breakpoints past the prologue. Also added a "-K" ↵Jim Ingham
argument to the relevant "break set" commands to set this per breakpoint. Also, some CreateBreakpoint API's in the lldb_private namespace had "internal" first and "skip_prologue" second. "internal should always be last. Fixed that. rdar://problem/11484729 llvm-svn: 157225
2012-04-23<rdar://problem/11282938>Greg Clayton
Fixed an issue where we get NULL compile units back from the symbol vendor. We need symbol vendors to be able to quickly give an estimate of the compile units that they have without having to fully vette them first, so anyone getting compile units from a module should be able to deal with a NULL compile unit being returned for a given index. llvm-svn: 155398

2011-09-21Add a new breakpoint type "break by source regular expression".Jim Ingham
Fix the RegularExpression class so it has a real copy constructor. Fix the breakpoint setting with multiple shared libraries so it makes one breakpoint not one per shared library. Add SBFileSpecList, to be used to expose the above to the SB interface (not done yet.) llvm-svn: 140225
2010-11-06Modified all logging calls to hand out shared pointers to make sure weGreg Clayton
don't crash if we disable logging when some code already has a copy of the logger. Prior to this fix, logs were handed out as pointers and if they were held onto while a log got disabled, then it could cause a crash. Now all logs are handed out as shared pointers so this problem shouldn't happen anymore. We are also using our new shared pointers that put the shared pointer count and the object into the same allocation for a tad better performance. llvm-svn: 118319
2010-10-28Check in an initial implementation of the "breakpoint clear" command, whose ↵Johnny Chen
purpose is clear the breakpoint associated with the (filename, line_number) combo when an arrow is pointing to a source position using Emacs Grand Unified Debugger library to interact with lldb. The current implmentation is insufficient in that it only asks the breakpoint whether it is associated with a breakpoint resolver with FileLine type and whether it matches the (filename, line_number) combo. There are other breakpoint resolver types whose breakpoint locations can potentially match the (filename, line_number) combo. The BreakpointResolver, BreakpointResolverName, BreakpointResolverAddress, and BreakpointResolverFileLine classes have extra static classof methods to support LLVM style type inquiry through isa, cast, and dyn_cast. The Breakpoint class has an API method bool GetMatchingFileLine(...) which is invoked from CommandObjectBreak.cpp to implement the "breakpoint clear" command. llvm-svn: 117562

2010-06-28Added function name types to allow us to set breakpoints by name moreGreg Clayton
intelligently. The four name types we currently have are: eFunctionNameTypeFull = (1 << 1), // The function name. // For C this is the same as just the name of the function // For C++ this is the demangled version of the mangled name. // For ObjC this is the full function signature with the + or // - and the square brackets and the class and selector eFunctionNameTypeBase = (1 << 2), // The function name only, no namespaces or arguments and no class // methods or selectors will be searched. eFunctionNameTypeMethod = (1 << 3), // Find function by method name (C++) with no namespace or arguments eFunctionNameTypeSelector = (1 << 4) // Find function by selector name (ObjC) names this allows much more flexibility when setting breakoints: (lldb) breakpoint set --name main --basename (lldb) breakpoint set --name main --fullname (lldb) breakpoint set --name main --method (lldb) breakpoint set --name main --selector The default: (lldb) breakpoint set --name main will inspect the name "main" and look for any parens, or if the name starts with "-[" or "+[" and if any are found then a full name search will happen. Else a basename search will be the default. Fixed some command option structures so not all options are required when they shouldn't be. Cleaned up the breakpoint output summary. Made the "image lookup --address <addr>" output much more verbose so it shows all the important symbol context results. Added a GetDescription method to many of the SymbolContext objects for the more verbose output. llvm-svn: 107075
