[lldb] Mark several tests as not dependent on debug info

2020-01-13T09:40:29+00:00

Summary: This just adds `NO_DEBUG_INFO_TESTCASE` to tests that don't really exercise anything debug information specific and therefore don't need to be rerun for all debug information variants.

This patch removes xfail decorator from some lldb testcases which are passing steadily now for past few week/months on aarch64/linux buildbot.

[lldb] [Process/NetBSD] Fix handling concurrent watchpoint events

2019-11-25T19:11:59+00:00

Fix handling concurrent watchpoint events so that they are reported correctly in LLDB. If multiple watchpoints are hit concurrently, the NetBSD kernel reports them as series of SIGTRAPs with a thread specified, and the debugger investigates DR6 in order to establish which watchpoint was hit. This is normally fine. However, LLDB disables and reenables the watchpoint on all threads after each hit, which results in the hit status from DR6 being wiped. As a result, it can't establish which watchpoint was hit in successive SIGTRAP processing. In order to workaround this problem, clear DR6 only if the breakpoint is overwritten with a new one. More specifically, move cleaning DR6 from ClearHardwareWatchpoint() to SetHardwareWatchpointWithIndex(), and do that only if the newly requested watchpoint is different from the one being set previously. This ensures that the disable-enable logic of LLDB does not clear watchpoint hit status for the remaining threads. This also involves refactoring of watchpoint logic. With the old logic, clearing watchpoint involved wiping dr6 & dr7, and setting it setting dr{0..3} & dr7. With the new logic, only enable bit is cleared from dr7, and the remaining bits are cleared/overwritten while setting new watchpoint. Differential Revision: https://reviews.llvm.org/D70025

[lldb] [Process/NetBSD] Improve threading support

2019-11-25T19:11:58+00:00

Implement major improvements to multithreaded program support. Notably, support tracking new and exited threads, associate signals and events with correct threads and support controlling individual threads when resuming. Firstly, use PT_SET_EVENT_MASK to enable reporting of created and exited threads via SIGTRAP. Handle TRAP_LWP events to keep track of the currently running threads. Secondly, update the signal (both generic and SIGTRAP) handling code to account for per-thread signals correctly. Signals delivered to the whole process are reported on all threads, while per-thread signals and events are reported only to the specific thread. The remaining threads are marked as 'stopped with no reason'. Note that NetBSD always stops all threads on debugger events. Thirdly, implement the ability to set every thread as running, stopped or single-stepping separately while continuing the process. This also provides the ability to send a signal to the whole process or to one of its thread while resuming. Differential Revision: https://reviews.llvm.org/D70022

[Windows] Add support of watchpoints to `ProcessWindows`

2019-09-06T05:37:03+00:00

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.

[dotest] Avoid the need for LEVEL= makefile boilerplate

2019-09-04T07:46:25+00:00

Summary: Instead of each test case knowing its depth relative to the test root, we can just have dotest add the folder containing Makefile.rules to the include path. This was motivated by r370616, though I have been wanting to do this ever since we moved to building tests out-of-tree. The only manually modified files in this patch are lldbinline.py and plugins/builder_base.py. The rest of the patch has been produced by this shell command: find . $ -name Makefile -o -name '*.mk' $ -exec sed --in-place -e '/LEVEL *:\?=/d' -e '1,2{/^$/d}' -e 's,\$(LEVEL)/,,' {} + Reviewers: teemperor, aprantl, espindola, jfb Subscribers: emaste, javed.absar, arichardson, christof, arphaman, lldb-commits Differential Revision: https://reviews.llvm.org/D67083 llvm-svn: 370845
