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
2017-02-16NPL: Fix single step workaroundPavel Labath
While refactoring the code in r293046 I made a very basic error - relying on destructor side-effects of a copyable object. Fix that and make the object non-copyable. This fixes the tests on the platforms that need this workaround, but unfortunately we don't have a way to make a more platform-agnostic test right now. llvm-svn: 295345
2017-01-25NPL: Compartmentalize arm64 single step workaround betterPavel Labath
The main motivation for me doing this is being able to build an arm android lldb-server against api level 9 headers, but it seems like a good cleanup nonetheless. The entirety of the cpu_set_t dance now resides in SingleStepCheck.cpp, which is only built on arm64. llvm-svn: 293046
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
2016-02-23Work around a stepping bug in arm64 android MPavel Labath
Summary: On arm64, linux<=4.4 and Android<=M there is a bug, which prevents single-stepping from working when the system comes back from suspend, because of incorrectly initialized CPUs. This did not really affect Android<M, because it did not use software suspend, but it is a problem for M, which uses suspend (doze) quite extensively. Fortunately, it seems that the first CPU is not affected by this bug, so this commit implements a workaround by forcing the inferior to execute on the first cpu whenever we are doing single stepping. While inside, I have moved the implementations of Resume() and SingleStep() to the thread class (instead of process).
