2023-03-27Revert "[lldb] Move UnixSignals creation into Platform plugins"Alex Langford
This reverts commit ee232506b870ce5282cc4da5ca493d41d361feb3. As discussed in https://reviews.llvm.org/D146668 we'll find another way forward.
2023-03-20[lldb] Move UnixSignals creation into Platform pluginsAlex Langford
The high level goal of this change is to remove lldbTarget's dependency on lldbPluginProcessUtility. The reason for this existing dependency is so that we can create the appropriate UnixSignals object based on an ArchSpec. Instead of using the ArchSpec, we can instead take advantage of the Platform associated with the current Target. This is accomplished by adding a new method to Platform, CreateUnixSignals, which will create the correct UnixSignals object for us. We then can use `Platform::GetUnixSignals` and rely on that to give us the correct signals as needed. Differential Revision: https://reviews.llvm.org/D146263
2023-03-20[lldb] Implement CrashReason using UnixSignalsDavid Spickett
By adding signal codes to UnixSignals and adding a new function where you can get a string with optional address and bounds. Added signal codes to the Linux, FreeBSD and NetBSD signal sets. I've checked the numbers against the relevant sources. Each signal code has a code number, description and printing options. By default you just get the descripton, you can opt into adding either a fault address or bounds information. Bounds signals we'll use the description, unless we have the bounds values in which case we say whether it is an upper or lower bound issue. GetCrashReasonString remains in CrashReason because we need it to be compiled only for platforms with siginfo_t. Ideally it would move into NativeProcessProtocol, but that is also used by NativeRegisterContextWindows, where there would be no siginfo_t.

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).

2019-01-19Update 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
2018-11-11Remove header grouping comments.Jonas Devlieghere
This patch removes the comments grouping header includes. They were added after running IWYU over the LLDB codebase. However they add little value, are often outdates and burdensome to maintain. llvm-svn: 346626

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

Summary: Signals 1-32 are matching the default UNIX platform. There are platform specific ones above 32. From the `/usr/include/sys/signal.h` header: ``` #define SIGPWR 32 /* power fail/restart (not reset when caught) */ #ifdef _KERNEL #define SIGRTMIN 33 /* Kernel only; not exposed to userland yet */ #define SIGRTMAX 63 /* Kernel only; not exposed to userland yet */ #endif ``` Reviewers: emaste, joerg Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D15482 llvm-svn: 255592
