* [Windows] Add support of watchpoints to `ProcessWindows`Aleksandr Urakov2019-09-061-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch adds support of watchpoints to the old `ProcessWindows` plugin. The `ProcessWindows` plugin uses the `RegisterContext` to set and reset watchpoints. The `RegisterContext` has some interface to access watchpoints, but it is very limited (e.g. it is impossible to retrieve the last triggered watchpoint with it), that's why I have implemented a slightly different interface in the `RegisterContextWindows`. Moreover, I have made the `ProcessWindows` plugin responsible for search of a vacant watchpoint slot, because watchpoints exist per-process (not per-thread), then we can place the same watchpoint in the same slot in different threads. With this scheme threads don't need to have their own watchpoint lists, and it simplifies identifying of the last triggered watchpoint.

* [NFC] Remove ASCII lines from commentsJonas Devlieghere2019-04-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | A lot of comments in LLDB are surrounded by an ASCII line to delimit the begging and end of the comment. Its use is not really consistent across the code base, sometimes the lines are longer, sometimes they are shorter and sometimes they are omitted. Furthermore, it looks kind of weird with the 80 column limit, where the comment actually extends past the line, but not by much. Furthermore, when /// is used for Doxygen comments, it looks particularly odd. And when // is used, it incorrectly gives the impression that it's actually a Doxygen comment. I assume these lines were added to improve distinguishing between comments and code. However, given that todays editors and IDEs do a great job at highlighting comments, I think it's worth to drop this for the sake of consistency. The alternative is fixing all the inconsistencies, which would create a lot more churn. Differential revision: https://reviews.llvm.org/D60508 llvm-svn: 358135
* 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

* Move RegisterValue,Scalar,State from Core to UtilityPavel Labath2018-08-071-1/+1
| | | | | | | | | | | | | These three classes have no external dependencies, but they are used from various low-level APIs. Moving them down to Utility improves overall code layering (although it still does not break any particular dependency completely). The XCode project will need to be updated after this change.

* [lldbsuite, windows] Don't crash LLDB when we try to retrieve a register on ↵Stella Stamenova2018-07-021-0/+3
| | | | | | | | | | | | | | | | Windows Summary: 1) When ReadRegister is called with a null register into on Windows, rather than crashing due to an access violation, simply return false. Not all registers and properties will be read or calculated correctly, but that is consistent with other platforms that also return false in that case 2) Update a couple of tests to reference pr37995 as their reason for failure since it is much more accurate. Support for floating point registers doesn't exist on Windows at all, rather than having issues.

* Normalize some lldb #include statements.James Y Knight2018-05-221-2/+2
| | | | | | | | | | | Most non-local includes of header files living under lldb/sources/ were specified with the full path starting after sources/. However, in a few instances, other sub-directories were added to include paths, or Normalize those few instances to follow the style used by the rest of the codebase, to make it easier to understand. llvm-svn: 333035
* [Windows, Process] LLDB reads wrong registers on 64bit WindowsStella Stamenova2018-05-171-16/+16
| | | | | | | | | | | | | | | | | | Summary: LLDB reads wrong registers on 64bit Windows because RegisterContextWindows_x64::GetRegisterInfoAtIndex returns wrong reference. I encountered broken backtrace when the program stopped at function which does not have prologue code, such as compiled with '-fomit-frame-pointer'. In this situation, CFA is equal to rsp but LLDB reads r9. RegisterContextWindows_x64::GetRegisterInfoAtIndex depends the order of lldb_XXX_x86_64 values, but RegisterIndex/g_register_infos/g_gpr_reg_indices does not follow order. In source/Plugins/Process/Utility/lldb-x86-register-enums.h The order of GPRs is rax, rbx, rcx, rdx, rdi, rsi, rbp, rsp, r8, ...

* Rename Error -> Status.Zachary Turner2017-05-121-1/+1
| | | | | | | | | | | | | | | 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
* Move classes from Core -> Utility.Zachary Turner2017-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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
* *** This commit represents a complete reformatting of the LLDB source codeKate Stone2016-09-061-211/+226
| | | | | | | | | | | | | | | | | | | | | | | *** 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
* (Minor tweak) Make RegisterContextWindows_x86/x64::GetRegisterInfoAtIndex Carlo Kok2016-06-061-1/+5
| | | | | | | | | | | | return NULL for an invalid register. The unwind logic asks for the "return address register" which doesn't exist on x86/x86_64, returns -1 and calls this with -1 as a parameter, ends up out of scope of the array bounds for g_register_infos and later SIGSEGVs on accessing. This now matches the other GetRegisterInfoAtIndex for other platforms. llvm-svn: 271876
