* 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.

* Reflow paragraphs in comments.Adrian Prantl2018-04-301-25/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is intended as a clean up after the big clang-format commit (r280751), which unfortunately resulted in many of the comment paragraphs in LLDB being very hard to read. FYI, the script I used was: import textwrap import commands import os import sys import re tmp = "%s.tmp"%sys.argv[1] out = open(tmp, "w+") with open(sys.argv[1], "r") as f: header = "" text = "" comment = re.compile(r'^( *//) ([^ ].*)$') special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$') for line in f: match = comment.match(line) if match and not special.match(match.group(2)): # skip intentionally short comments. if not text and len(match.group(2)) < 40: out.write(line) continue if text: text += " " + match.group(2) else: header = match.group(1) text = match.group(2) continue if text: filled = textwrap.wrap(text, width=(78-len(header)), break_long_words=False) for l in filled: out.write(header+" "+l+'\n') text = "" out.write(line) os.rename(tmp, sys.argv[1]) Differential Revision: https://reviews.llvm.org/D46144 llvm-svn: 331197
* Clean up NativeRegisterContextPavel Labath2017-11-101-12/+10
| | | | | | | | | | | | | | | | | | | | | Summary: This commit removes the concrete_frame_idx member from NativeRegisterContext and related functions, which was always set to zero and never used. I also change the native thread class to store a NativeRegisterContext as a unique_ptr (documenting the ownership) and make sure it is always initialized (most of the code was already blindly dereferencing the register context pointer, assuming it would always be present -- this makes its treatment consistent).

* Rename Error -> Status.Zachary Turner2017-05-121-58/+61
| | | | | | | | | | | | | | | 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 Log from Core -> Utility.Zachary Turner2017-03-031-1/+1
| | | | | | | | | All references to Host and Core have been removed, so this class can now safely be lowered into Utility. Differential Revision: https://reviews.llvm.org/D30559 llvm-svn: 296909
* Merge Linux and FreeBSD arm register contextsPavel Labath2017-02-271-2/+2
| | | | | | | | | | | | | | Summary: These two register contexts were identical, so this shouldn't cause any regressions, but I'd appreciate it if you can check that this at least compiles.

* 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
* Revert unwanted changes in lldb when updating llvm::Error()Mehdi Amini2016-11-111-6/+6

* Make the Error class constructor protectedMehdi Amini2016-11-111-6/+6

* *** This commit represents a complete reformatting of the LLDB source codeKate Stone2016-09-061-898/+747
| | | | | | | | | | | | | | | | | | | | | | | *** 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

* Adds support for hardware watchpoints on Arm targets.Omair Javaid2015-08-251-0/+484
| | | | | | | | | | | | | | http://reviews.llvm.org/D9703 This updated patches correct problems in arm hardware watchpoint support patch posted earlier. This patch has been tested on samsung chromebook (ARM - Linux) and PandaBoard using basic watchpoint test application. Also it was tested on Nexus 7 Android device. On chromebook linux we are able to set and clear all types of watchpoints but on android we end up getting a watchpoint packet error because we are not able to call hardware watchpoint ptrace functions successfully. llvm-svn: 245961
* Move register reading form NativeProcessLinux to NativeRegisterContextLinux*Tamas Berghammer2015-05-261-197/+31
| | | | | | | | | | | | | | | | | This change reorganize the register read/write code inside lldb-server on Linux with moving the architecture independent code into a new class called NativeRegisterContextLinux and all of the architecture dependent code into the appropriate NativeRegisterContextLinux_* class. As part of it the compilation of the architecture specific register contexts are only compiled on the specific architecture because they can't be used in other cases. The purpose of this change is to remove a lot of duplicated code from the different register contexts and to remove the architecture dependent codes from the global NativeProcessLinux class.
