2022-02-03[lldb] Rename Logging.h to LLDBLog.h and clean up includesPavel Labath
Most of our code was including Log.h even though that is not where the "lldb" log channel is defined (Log.h defines the generic logging infrastructure). This worked because Log.h included Logging.h, even though it should. After the recent refactor, it became impossible the two files include each other in this direction (the opposite inclusion is needed), so this patch removes the workaround that was put in place and cleans up all files to include the right thing. It also renames the file to LLDBLog to better reflect its purpose.

2020-06-24[lldb] Use std::make_unique<> (NFC)Jonas Devlieghere
Update the rest of lldb to use std::make_unique<>. I used clang-tidy to automate this, which probably missed cases that are wrapped in ifdefs.
2020-03-18[lldb/MemoryHistoryAsan] Fix address resolution for recorded backtracesFred Riss
Summary: The memory history plugin for Asan creates a HistoryThread with the recorded PC values provided by the Asan runtime. In other cases, thoses PCs are gathered by LLDB directly. The PCs returned by the Asan runtime are the PCs of the calls in the backtrace, not the return addresses you would normally get when unwinding the stack (look for a call to GetPreviousIntructionPc in AsanGetStack). When the above addresses are passed to the unwinder, it will subtract 1 from each address of the non zero frames because it treats them as return addresses. This can lead to the final report referencing the wrong line. This patch fixes this issue by threading a flag through HistoryThread and HistoryUnwinder that tells them to treat every frame like the first one. The Asan MemoryHistory plugin can then use this flag. This fixes running TestMemoryHistory on arm64 devices, although it's hard to guarantee that the test will continue to exhibit the boundary condition that triggers this bug.

2020-01-24[lldb][NFC] Fix all formatting errors in .cpp file headersRaphael Isemann
Summary: A *.cpp file header in LLDB (and in LLDB) should like this: ``` //===-- TestUtilities.cpp -------------------------------------------------===// ``` However in LLDB most of our source files have arbitrary changes to this format and these changes are spreading through LLDB as folks usually just use the existing source files as templates for their new files (most notably the unnecessary editor language indicator `-*- C++ -*-` is spreading and in every review someone is pointing out that this is wrong, resulting in people pointing out that this is done in the same way in other files). This patch removes most of these inconsistencies including the editor language indicators, all the different missing/additional '-' characters, files that center the file name, missing trailing `===//` (mostly caused by clang-format breaking the line).

2019-07-24[Logging] Replace Log::Printf with LLDB_LOG macro (NFC)Jonas Devlieghere
This patch replaces explicit calls to log::Printf with the new LLDB_LOGF macro. The macro is similar to LLDB_LOG but supports printf-style format strings, instead of formatv-style format strings. So instead of writing: if (log) log->Printf("%s\n", str); You'd write: LLDB_LOG(log, "%s\n", str); This change was done mechanically with the command below. I replaced the spurious if-checks with vim, since I know how to do multi-line replacements with it. find . -type f -name '*.cpp' -exec \ sed -i '' -E 's/log->Printf\(/LLDB_LOGF\(log, /g' "{}" + Differential revision: https://reviews.llvm.org/D65128 llvm-svn: 366936

2019-05-23[lldb] NFC modernize codebase with modernize-use-nullptrKonrad Kleine
Summary: NFC = [[ https://llvm.org/docs/Lexicon.html#nfc | Non functional change ]] This commit is the result of modernizing the LLDB codebase by using `nullptr` instread of `0` or `NULL`. See https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-nullptr.html for more information. This is the command I ran and I to fix and format the code base: ``` run-clang-tidy.py \ -header-filter='.*' \ -checks='-*,modernize-use-nullptr' \ -fix ~/dev/llvm-project/lldb/.* \ -format \ -style LLVM \ -p ~/llvm-builds/debug-ninja-gcc ``` NOTE: There were also changes to `llvm/utils/unittest` but I did not include them because I felt that maybe this library shall be updated in isolation somehow. NOTE: I know this is a rather large commit but it is a nobrainer in most parts.

2019-02-13Replace 'ap' with 'up' suffix in variable names. (NFC)Jonas Devlieghere
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
2019-02-11Use std::make_shared in LLDB (NFC)Jonas Devlieghere
Unlike std::make_unique, which is only available since C++14, std::make_shared is available since C++11. Not only is std::make_shared a lot more readable compared to ::reset(new), it also performs a single heap allocation for the object and control block.

2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth
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

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

2016-05-18remove use of Mutex in favour of std::{,recursive_}mutexSaleem Abdulrasool
This is a pretty straightforward first pass over removing a number of uses of Mutex in favor of std::mutex or std::recursive_mutex. The problem is that there are interfaces which take Mutex::Locker & to lock internal locks. This patch cleans up most of the easy cases. The only non-trivial change is in CommandObjectTarget.cpp where a Mutex::Locker was split into two. llvm-svn: 269877
