* Remove an expensive lock from TimerPavel Labath2017-05-151-2/+2
| | | | | | | | | | | | | The Timer destructor would grab a global mutex in order to update execution time. Add a class to define a category once, statically; the class adds itself to an atomic singly linked list, and thus subsequent updates only need to use an atomic rather than grab a lock and perform a hashtable lookup.

* Rename Error -> Status.Zachary Turner2017-05-121-5/+5
| | | | | | | | | | | | | | | 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

* iwyu fixes for lldbCore.Zachary Turner2017-04-061-22/+31
| | | | | | | | | | | | | | This adjusts header file includes for headers and source files in Core. In doing so, one dependency cycle is eliminated because all the includes from Core to that project were dead includes anyway. In places where some files in other projects were only compiling due to a transitive include from another header, fixups have been made so that those files also include the header they need. Tested on Windows and Linux, and plan to address failures on OSX and FreeBSD after watching the bots. llvm-svn: 299714

* Move classes from Core -> Utility.Zachary Turner2017-02-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | This moves the following classes from Core -> Utility. 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
* Rewrite all Property related functions in terms of StringRef.Zachary Turner2016-11-171-3/+2
| | | | | | | | | | | | | | | This was a bit tricky, especially for things like OptionValueArray and OptionValueDictionary since they do some funky string parsing. Rather than try to re-write line-by-line I tried to make the StringRef usage idiomatic, even though it meant often re-writing from scratch large blocks of code in a different way while keeping true to the original intent. The finished code is a big improvement though, and often much shorter than the original code. All tests and unit tests pass on Windows and Linux. llvm-svn: 287242
* Don't allow direct access to StreamString's internal buffer.Zachary Turner2016-11-161-1/+1
| | | | | | | | | | | | | | | This is a large API change that removes the two functions from StreamString that return a std::string& and a const std::string&, and instead provide one function which returns a StringRef. Direct access to the underlying buffer violates the concept of a "stream" which is intended to provide forward only access, and makes porting to llvm::raw_ostream more difficult in the future.

* add stop column highlighting supportTodd Fiala2016-09-211-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces optional marking of the column within a source line where a thread is stopped. This marking will show up when the source code for a thread stop is displayed, when the debug info knows the column information, and if the optional column marking is enabled. There are two separate methods for handling the marking of the stop column: * via ANSI terminal codes, which are added inline to the source line display. The default ANSI mark-up is to underline the column. * via a pure text-based caret that is added in the appropriate column in a newly-inserted blank line underneath the source line in question. There are some new options that control how this all works. * settings set stop-show-column This takes one of 4 values: * ansi-or-caret: use the ANSI terminal code mechanism if LLDB is running with color enabled; if not, use the caret-based, pure text method (see the "caret" mode below). * ansi: only use the ANSI terminal code mechanism to highlight the stop line. If LLDB is running with color disabled, no stop column marking will occur. * caret: only use the pure text caret method, which introduces a newly-inserted line underneath the current line, where the only character in the new line is a caret that highlights the stop column in question. * none: no stop column marking will be attempted. * settings set stop-show-column-ansi-prefix This is a text format that indicates the ANSI formatting code to insert into the stream immediately preceding the column where the stop column character will be marked up. It defaults to ${ansi.underline}; however, it can contain any valid LLDB format codes, e.g. ${ansi.fg.red}${ansi.bold}${ansi.underline} * settings set stop-show-column-ansi-suffix This is the text format that specifies the ANSI terminal codes to end the markup that was started with the prefix described above. It defaults to: ${ansi.normal}. This should be sufficient for the common cases. Significant leg-work was done by Adrian Prantl.

* I'm experimenting with changing how the mixed source & assemblyJason Molenda2016-09-081-32/+269
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mode in lldb works. I've been discussing this with Jim Ingham, Greg Clayton, and Kate Stone for the past week or two. Previously lldb would print three source lines (centered on the line table entry line for the current line) followed by the assembly. It would print the context information (module`function + offset) before those three lines of source. Now lldb will print up to two lines before/after the line table entry. It prints two '*' characters for the line table line to make it clear what line is showing assembly. There is one line of whitespace before/after the source lines so the separation between source & assembly is clearer. I don't print the context line (module`function + offset). I stop printing context lines if it's a different line table entry, or if it's a source line I've already printed as context to another source line. If I have two line table entries one after another for the same source line (I get these often with clang - with different column information in them), I only print the source line once. I'm also using the target.process.thread.step-avoid-regexp setting (which keeps you from stepping into STL functions that have been inlined into your own code) and avoid printing any source lines from functions that match that regexp. When lldb disassembles into a new function, it will try to find the declaration line # for the function and print all of the source lines between the decl and the first line table entry (usually a { curly brace) so we have a good chance of including the arguments, at least with the debug info emitted by clang. Finally, the # of source lines of context to show has been separated from whether we're doing mixed source & assembly or not. Previously specifying 0 lines of context would turn off mixed source & assembly. I think there's room for improvement, and maybe some bugs I haven't found yet, but it's in good enough shape to upstream and iterate at this point. I'm not sure how best to indicate which source line is the actual line table # versus context lines. I'm using '**' right now. Both Kate and Greg had the initial idea to reuse '->' (normally used to indicate "currently executing source line") - I tried it but I wasn't thrilled, I'm too used to the established meaning of ->. Greg had the interesting idea of avoiding context source lines only in two line table entries in the same source file. So we'd print two lines before & after a source line, and then the next line table entry (if it was on the next source line after those two context lines) we'd display only the following two lines -- the previous two had just been printed. If an inline source line was printed between these two, though, we'd print the context lines for both of them. It's an interesting idea, and I want to see how it works with both -O0 and -O3 codegen where we have different amounts of inlining. <rdar://problem/27961419> llvm-svn: 280906
* *** This commit represents a complete reformatting of the LLDB source codeKate Stone2016-09-061-1126/+897
| | | | | | | | | | | | | | | | | | | | | | | *** 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
* Delete Host/windows/win32.hZachary Turner2016-08-091-1/+1
| | | | | | | | | | | | | | | | | | | It's always hard to remember when to include this file, and when you do include it it's hard to remember what preprocessor check it needs to be behind, and then you further have to remember whether it's windows.h or win32.h which you need to include. This patch changes the name to PosixApi.h, which is more appropriately named, and makes it independent of any preprocessor setting. There's still the issue of people not knowing when to include this, because there's not a well-defined set of things it exposes other than "whatever is missing on Windows", but at least this should make it less painful to fix when problems arise. This patch depends on LLVM revision r278170. llvm-svn: 278177

Also call this from the arm instruction emulation code. The determination of whether a given ArchSpec is thumb-only is still a bit of a hack, but at least the hack is consolidated into a single place. In my original version of this patch http://reviews.llvm.org/D13578 I was calling into llvm's feature arm feature tables to make this determination, like #include "llvm/Support/TargetRegistry.h" #include "llvm/MC/MCSubtargetInfo.h" #include "llvm/../../lib/Target/ARM/ARMGenRegisterInfo.inc" #include "llvm/../../lib/Target/ARM/ARMFeatures.h" [...] std::string triple (GetTriple().getTriple()); const char *cpu = ""; const char *features_str = ""; const llvm::Target *curr_target = llvm::TargetRegistry::lookupTarget(triple.c_str(), Error); std::unique_ptr<llvm::MCSubtargetInfo> subtarget_info_up (curr_target->createMCSubtargetInfo(triple.c_str(), cpu, features_str)); if (subtarget_info_up->getFeatureBits()[llvm::ARM::FeatureNoARM]) { return true; } but those tables are post-llvm-build generated and linking against them for all of our different build system methods was a big hiccup that I haven't had time to revisit convincingly. I'll keep that reviews.llvm.org patch around to remind myself that I need to take another run at linking against the necessary tables again in llvm. <rdar://problem/23022803> llvm-svn: 265377

| | | | | | | | | | | | | | | | | | | | lldb_private::CompilerDeclContext and renames ClangType to CompilerType in many accessors and functions. Create a new "lldb_private::CompilerDeclContext" class that will replace all direct uses of "clang::DeclContext" when used in compiler agnostic code, yet still allow for conversion to clang::DeclContext subclasses by clang specific code. This completes the abstraction of type parsing by removing all "clang::" references from the SymbolFileDWARF. The new "lldb_private::CompilerDeclContext" class abstracts decl contexts found in compiler type systems so they can be used in internal API calls. The TypeSystem is required to support CompilerDeclContexts with new pure virtual functions that start with "DeclContext" in the member function names. Converted all code that used lldb_private::ClangNamespaceDecl over to use the new CompilerDeclContext class and removed the ClangNamespaceDecl.cpp and ClangNamespaceDecl.h files. Removed direct use of clang APIs from SBType and now use the abstract type systems to correctly explore types. Bulk renames for things that used to return a ClangASTType which is now CompilerType: "Type::GetClangFullType()" to "Type::GetFullCompilerType()" "Type::GetClangLayoutType()" to "Type::GetLayoutCompilerType()" "Type::GetClangForwardType()" to "Type::GetForwardCompilerType()" "Value::GetClangType()" to "Value::GetCompilerType()" "Value::SetClangType (const CompilerType &)" to "Value::SetCompilerType (const CompilerType &)" "ValueObject::GetClangType ()" to "ValueObject::GetCompilerType()" many more renames that are similar. llvm-svn: 245905

* Resubmitting 240466 after fixing the linux test suite failures.Greg Clayton2015-06-251-1/+1
| | | | | | | | | | | | | | | A few extras were fixed - Symbol::GetAddress() now returns an Address object, not a reference. There were places where people were accessing the address of a symbol when the symbol's value wasn't an address symbol. On MacOSX, undefined symbols have a value zero and some places where using the symbol's address and getting an absolute address of zero (since an Address object with no section and an m_offset whose value isn't LLDB_INVALID_ADDRESS is considered an absolute address). So fixing this required some changes to make sure people were getting what they expected. - Since some places want to access the address as a reference, I added a few new functions to symbol: Address &Symbol::GetAddressRef(); const Address &Symbol::GetAddressRef() const; Linux test suite passes just fine now. <rdar://problem/21494354> llvm-svn: 240702

* Get rid of Debugger::FormatPrompt() and replace it with the new FormatEntity ↵Greg Clayton2015-02-041-12/+15
| | | | | | | | | | | | | | | | | | | class. Why? Debugger::FormatPrompt() would run through the format prompt every time and parse it and emit it piece by piece. It also did formatting differently depending on which key/value pair it was parsing. The new code improves on this with the following features: 1 - Allow format strings to be parsed into a FormatEntity::Entry which can contain multiple child FormatEntity::Entry objects. This FormatEntity::Entry is a parsed version of what was previously always done in Debugger::FormatPrompt() so it is more efficient to emit formatted strings using the new parsed FormatEntity::Entry. 2 - Allows errors in format strings to be shown immediately when setting the settings (frame-format, thread-format, disassembly-format 3 - Allows auto completion by implementing a new OptionValueFormatEntity and switching frame-format, thread-format, and disassembly-format settings over to using it. 4 - The FormatEntity::Entry for each of the frame-format, thread-format, disassembly-format settings only replaces the old one if the format parses correctly 5 - Combines all consecutive string values together for efficient output. This means all "${ansi.*}" keys and all desensitized characters like "\n" "\t" "\0721" "\x23" will get combined with their previous strings 6 - ${*.script:} (like "${var.script:mymodule.my_var_function}") have all been switched over to use ${script.*:} "${script.var:mymodule.my_var_function}") to make the format easier to parse as I don't believe anyone was using these format string power user features. 7 - All key values pairs are defined in simple C arrays of entries so it is much easier to add new entries. These changes pave the way for subsequent modifications where we can modify formats to do more (like control the width of value strings can do more and add more functionality more easily like string formatting to control the width, printf formats and more). llvm-svn: 228207

| | | | | | | | Name matching was working inconsistently across many places in LLDB. Anyone doing name lookups where you want to look for all types of names should used "eFunctionNameTypeAuto" as the sole name type mask. This will ensure that we get consistent "lookup function by name" results. We had many function calls using as mask like "eFunctionNameTypeBase | eFunctionNameTypeFull | eFunctionNameTypeMethod | eFunctionNameTypeSelector". This was due to the function lookup by name evolving over time, but as it stands today, use eFunctionNameTypeAuto when you want general name lookups. Either ModuleList::FindFunctions() or Module::FindFunctions() will figure out the right kinds of names to lookup and remove the "eFunctionNameTypeAuto" and replace it with the exact subset of what the name can be. This checkin also changes eFunctionNameTypeAny over to use eFunctionNameTypeAuto to reflect this. llvm-svn: 182179

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <rdar://problem/13594769> Main changes in this patch include: - cleanup plug-in interface and use ConstStrings for plug-in names - Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp - Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging The plug-in interface changes: Modified the lldb_private::PluginInterface class that all plug-ins inherit from: Changed: virtual const char * GetPluginName() = 0; To: virtual ConstString GetPluginName() = 0; Removed: virtual const char * GetShortPluginName() = 0; - Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. - Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc. llvm-svn: 181631
* After discussing with Chris Lattner, we require C++11, so lets get rid of ↵Greg Clayton2013-04-181-3/+3
| | | | | | the macros and just use C++11. llvm-svn: 179805
* Since we use C++11, we should switch over to using std::unique_ptr when ↵Greg Clayton2013-04-181-3/+3
| | | | | | | | C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++. Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro. llvm-svn: 179779

| | | | | | Make lldb_private::RegularExpression thread safe everywhere. This was done by removing the m_matches array from the lldb_private::RegularExpression class and putting it into the new lldb_private::RegularExpression::Match class. When executing a regular expression you now have the option to create a lldb_private::RegularExpression::Match object and pass a pointer in if you want to get parenthesized matching. If you don't want any matching, you pass in NULL. The lldb_private::RegularExpression::Match object is initialized with the number of matches you desire. Any matching strings are now extracted from the lldb_private::RegularExpression::Match objects. This makes the regular expression objects thread safe and as a result many more regex objects were turned into static objects that end up using a local lldb_private::RegularExpression::Match object when executing. llvm-svn: 178702

| | | | | | | | | | PC relative loads are missing disassembly comments when disassembled in a live process. This issue was because some sections, like __TEXT and __DATA in libobjc.A.dylib, were being moved when they were put into the dyld shared cache. This could also affect any other system that slides sections individually. The solution is to keep track of wether the bytes we will disassemble are from an executable file (file address), or from a live process (load address). We now do the right thing based off of this input in all cases. llvm-svn: 178315
