* Add setting to require hardware breakpoints.Jonas Devlieghere2018-11-154-1/+121
| | | | | | | | | | | | | | | | When debugging read-only memory we cannot use software breakpoint. We already have support for hardware breakpoints and users can specify them with `-H`. However, there's no option to force LLDB to use hardware breakpoints internally, for example while stepping. This patch adds a setting target.require-hardware-breakpoint that forces LLDB to always use hardware breakpoints. Because hardware breakpoints are a limited resource and can fail to resolve, this patch also extends error handling in thread plans, where breakpoints are used for stepping.

| | | | | | | | | | | | | | | | | | | | | | | | | qWatchpointSupportInfo packet correctly. In GDBRemoteCommunicationClient::GetWatchpointSupportInfo, if the response to qWatchpointSupportInfo does not include the 'num' field, then we did not get an answer we understood, mark this target as not supporting that packet. In Target.cpp, rename the very confusingly named CheckIfWatchpointsExhausted to CheckIfWatchpointsSupported, and check the error status returned by Process::GetWatchpointSupportInfo. If we cannot determine what the number of supported watchpoints are, assume that they will work. We'll handle the failure later when we try to create/enable the watchpoint if the Z2 packet isn't supported. Add a gdb_remote_client test case. <rdar://problem/42621432> llvm-svn: 346561
* [lldb] Introduce StackFrameRecognizer [take 3]Kuba Mracek2018-10-314-0/+161
| | | | | | | | This patch introduces a concept of "frame recognizer" and "recognized frame". This should be an extensible mechanism that retrieves information about special frames based on ABI, arguments or other special properties of that frame, even without source code. A few examples where that could be useful could be 1) objc_exception_throw, where we'd like to get the current exception, 2) terminate_with_reason and extracting the current terminate string, 3) recognizing Objective-C frames and automatically extracting the receiver+selector, or perhaps all arguments (based on selector).

| | | | | | | | | | | | | | | | | | | | | | Add support in ProcessGDBRemote::GetGDBServerRegisterInfo for recognizing a generic "arm" architecture that will be used if nothing better is available so that we don't ignore the register definitions if we didn't already have an architecture set. Also in ProcessGDBRemote::DoConnectRemote don't set the target arch unless we have a valid architecture to set it to. Platform::ConnectProcess will try to get the current target's architecture, or the default architecture, when creating the target for the connection to be attempted. If lldb was started with a target binary, we want to create this target with that architecture in case the remote gdb stub doesn't supply a qHostInfo arch. Add logging to Target::MergeArchitecture. <rdar://problem/34916465> llvm-svn: 345106

* Use a relaxed substring check for function names in a testVedant Kumar2018-10-161-2/+7
| | | | | | | | | | | The TestTailCallFrameSBAPI.py test checks that function names in a backtrace are equal to an expected value. Use a relaxed substring check because function dislpay names are platform-dependent. E.g we see "void sink(void)" on Windows, but "sink()" on Darwin. This seems like a bug -- just work around it for now. llvm-svn: 344634

The names of the class/test pairs *have to* always be unique. The easiest way to achieve that is to name each class differently (usually the same as the file name).

* Add support for artificial tail call framesVedant Kumar2018-10-0530-0/+567
| | | | | | | | | | | | | | | | This patch teaches lldb to detect when there are missing frames in a backtrace due to a sequence of tail calls, and to fill in the backtrace with artificial tail call frames when this happens. This is only done when the execution history can be determined from the call graph and from the return PC addresses of calls on the stack. Ambiguous sequences of tail calls (e.g anything involving tail calls and recursion) are detected and ignored. Depends on D49887.

* DWARFExpression: Resolve file addresses in the linked moduleAdrian Prantl2018-10-024-0/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a follow-up to https://reviews.llvm.org/D46362. When evaluating a complex expression in DWARFExpression::Evaluate, file addresses must be resolved to load addresses before we can perform operations such as DW_OP_deref on them. For this the address goes through three steps 1. Read the file address as stored in the DWARF 2. Link/relocate the file address (when reading from a .dSYM, this is a no-op) 3. Convert the file address to a load address. D46362 implemented step (3) by resolving the file address using the Module that the original DWARF came from. In the case of a dSYM that is correct, but when reading from .o files, we need to look up relocated/linked addresses, so the right place to look them up is the current frame's module. This patch fixes that by setting the expression's Module to point to the linked debugmap object. A word a bout the unorthodox testcase: The motivating testcase for this fix is in Swift, but I managed to hand-modify LLVM-IR for a trivial C program to exhibit the same problem, so we can fix this in llvm.org. rdar://problem/44689915 Differential Revision: https://reviews.llvm.org/D52678 llvm-svn: 343612

* [target] Change target create's behavior wrt loading dependent files.Jonas Devlieghere2018-09-205-0/+151
| | | | | | | | | | | | | | | | | | | | When creating a target, lldb loads all dependent files (i.e. libs in LC_LOAD_DYLIB for Mach-O). This can be confusing, especially when two versions of the same library end up in the shared cache. It's possible to change this behavior, by specifying target create -d <target> these dependents are not loaded. This patch changes the default behavior to only load dependent files only when the target is an executable. When creating a target for a library, it is now no longer necessary to pass -d. The user can still override this behavior by specifying the -d option to change this behavior. rdar://problem/43721382 Differential revision: https://reviews.llvm.org/D51934 llvm-svn: 342634

* Add support for descriptions with command completions.Raphael Isemann2018-09-131-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch adds a framework for adding descriptions to the command completions we provide. It also adds descriptions for completed top-level commands so that we can test this code. Completions are in general supposed to be displayed alongside the completion itself. The descriptions can be used to provide additional information about the completion to the user. Examples for descriptions are function signatures when completing function calls in the expression command or the binary name when providing completion for a symbol. There is still some boilerplate code from the old completion API left in LLDB (mostly because the respective APIs are reused for non-completion related purposes, so the CompletionRequest doesn't make sense to be used), so that's why I still had to change some function signatures. Also, as the old API only passes around a list of matches, and the descriptions are for these functions just another list, I had to add some code that essentially just ensures that both lists are always the same side (e.g. all the manual calls to `descriptions->AddString(X)` below a `matches->AddString(Y)` call). The initial command descriptions that come with this patch are just reusing the existing short help that is already added in LLDB. An example completion with descriptions looks like this: ``` (lldb) pl Available completions: platform -- Commands to manage and create platforms. plugin -- Commands for managing LLDB plugins. ``` Reviewers: #lldb, jingham Reviewed By: #lldb, jingham Subscribers: jingham, JDevlieghere, lldb-commits Differential Revision: https://reviews.llvm.org/D51175 llvm-svn: 342181
