* [lldb] Code cleanup: FormattersContainer.h: Use range-based for loops.Jan Kratochvil2019-09-141-12/+9
| | | | | | | Suggested for an other loop by Pavel Labath in: https://reviews.llvm.org/D66654#inline-605808 llvm-svn: 371922
* [Reproducer] Add reproducer dump command.Jonas Devlieghere2019-09-134-2/+266
| | | | | | | | | | | This adds a reproducer dump commands which makes it possible to inspect a reproducer from inside LLDB. Currently it supports the Files, Commands and Version providers. I'm planning to add support for the GDB Remote provider in a follow-up patch. Differential revision: https://reviews.llvm.org/D67474 llvm-svn: 371909
* [Reproducer] Move GDB Remote Packet into Utility. (NFC)Jonas Devlieghere2019-09-1317-246/+237
| | | | | | | | | | | | | | To support dumping the reproducer's GDB remote packets, we need the (de)serialization logic to live in Utility rather than the GDB remote plugin. This patch renames StreamGDBRemote to GDBRemote and moves the relevant packet code there. Its uses in the GDBRemoteCommunicationHistory and the GDBRemoteCommunicationReplayServer are updated as well.

* [test] Update TestAPILog to pass on Windows.Jonas Devlieghere2019-09-131-2/+2
| | | | | | | The pretty function macro is including __cdecl on Windows, which was causing the pattern matching to fail. This should fix that. llvm-svn: 371905

* [test] Print the log output on failure.Jonas Devlieghere2019-09-131-2/+2
| | | | | | | | This ensures that if the assertion fails we dump the log content. This should help me investigate what the output looks like on Windows, where the test is failing. llvm-svn: 371899

* [Reproducer] Include the this pointer in the API log.Jonas Devlieghere2019-09-132-10/+58
| | | | | | | | | | | | | | | The new centralized way of doing API logging through the reproducer macros is lacking a way to easily correlate instances of API objects. Logging the this pointer makes that significantly easier. For methods this is now always passed as the first argument, similar to the self argument in Python. This patch also adds a test case for API logging, which uncovered that we were not quoting strings. Differential revision: https://reviews.llvm.org/D67538 llvm-svn: 371885

* [lldb][NFC] Remove ArgEntry::ref memberRaphael Isemann2019-09-1328-121/+120
| | | | | | | | | | | The StringRef should always be identical to the C string, so we might as well just create the StringRef from the C-string. This might be slightly slower until we implement the storage of ArgEntry with a string instead of a std::unique_ptr<char[]>. Until then we have to do the additional strlen on the C string to construct the StringRef. llvm-svn: 371842
* [lldb][NFC] Simplify Args::ReplaceArgumentAtIndexRaphael Isemann2019-09-131-9/+2
| | | | | | | | | This code is not on any performance critical path that would justify this shortening optimization. It also makes it possible to turn 'ref' into a function (as this is the only place where we modify this ArgEntry member). llvm-svn: 371836
* [lldb][NFC] Make ArgEntry::quote private and provide a getterRaphael Isemann2019-09-134-4/+5

* For PR17164: split -fno-lax-vector-conversion into three differentRichard Smith2019-09-131-1/+1
| | | | | | | | | | | | | | | | | | | | | levels: -- none: no lax vector conversions [new GCC default] -- integer: only conversions between integer vectors [old GCC default] -- all: all conversions between same-size vectors [Clang default] For now, Clang still defaults to "all" mode, but per my proposal on cfe-dev (2019-04-10) the default will be changed to "integer" as soon as that doesn't break lots of testcases. (Eventually I'd like to change the default to "none" to match GCC and general sanity.) Following GCC's behavior, the driver flag -flax-vector-conversions is translated to -flax-vector-conversions=integer. This reinstates r371805, reverted in r371813, with an additional fix for lldb. llvm-svn: 371817
* [Target] Move InferiorCall to ProcessAlex Langford2019-09-134-66/+62
| | | | | | | | | | | | | | | | | | | Summary: InferiorCall is only ever used in Process, and it is not specific to POSIX. By moving it to Process, we can remove all dependencies on plugins from Process. Moving InferiorCall to Process seems to achieve this quite well. Additionally, the name InferiorCall is a little vague now, so we rename it something a bit more specific.

* [lldb][NFC] Simplify makefiles also for breakpoint testsRaphael Isemann2019-09-1230-90/+30
| | | | | | | | These tests were temporarily missing when the big Makefile simplification patch landed, so this just applies the same change to these tests. llvm-svn: 371738
* [lldb] Remove duplicated breakpoint testsRaphael Isemann2019-09-129-502/+0
| | | | | | | | | | | | | | | | | After reverting the deletion of the functionalities/breakpoint tests, we now have some tests twice in the test/ folder which breaks dotest: * commands/breakpoint/basic * functionalities/breakpoint/breakpoint_command After looking over these tests, I think it makes sense to only keep the original functionalities/ folder. The commands/breakpoint/basic test are not exclusively testing the breakpoint command itself, so they shouldn't be in commands/ in the first place. Note that these folders have identical contents (beside small adjustments regarding the Makefile which landed after the restructuring). llvm-svn: 371734
* [Reproducer] Move the command loader into the reproducer (NFC)Jonas Devlieghere2019-09-113-48/+53
| | | | | | | | This just moves the CommandLoader utility into the reproducer namespace and makes it accessible outside the API layer. This is setting things up for a bigger change. llvm-svn: 371689

* [Reproducer] Move GDB Remote Provider into Reproducer (NFC)Jonas Devlieghere2019-09-113-44/+45
| | | | | | | | | | | | | | Originally the idea was for providers to be defined close to where they are used. While this helped designing the providers in such a way that they don't depend on each other, it also means that it's not possible to access them from a central place. This proved to be a problem for some providers and resulted in them living in the reproducer class. The ProcessGDBRemote provider is the last remaining exception. This patch makes things consistent and moves it into the reproducer like the other providers. llvm-svn: 371685
* [DWARF] Evaluate DW_OP_entry_valueVedant Kumar2019-09-119-8/+557

* [Plugins/Process] Remove direct use of ClangASTContext from InferiorCallPOSIXAlex Langford2019-09-111-11/+21
| | | | | | | | | | | | | Summary: InferiorCallPOSIX directly grabs a ClangASTContext from the Target it has and does no error checking. I don't think these functions have a reason to know about clang specifically. Additionally, using `GetScratchTypeSystemForLanguage` forces us to do error checking since it returns an Expected.

* [lldb][NFC] Make include directories in Clang expression parser a std::stringRaphael Isemann2019-09-114-11/+10
| | | | | | | | | We never compare these directories (where ConstString would be good) and essentially just convert this back to a normal string in the end. So we might as well just use std::string. Also makes it easier to unittest this code (which was the main motivation for this change). llvm-svn: 371623

* [LLDB][ELF] Load both, .symtab and .dynsym sectionsKonrad Kleine2019-09-116-9/+119
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This change ensures that the .dynsym section will be parsed even when there's already is a .symtab. It is motivated because of minidebuginfo (https://sourceware.org/gdb/current/onlinedocs/gdb/MiniDebugInfo.html#MiniDebugInfo). There it says: Keep all the function symbols not already in the dynamic symbol table. That means the .symtab embedded inside the .gnu_debugdata does NOT contain the symbols from .dynsym. But in order to put a breakpoint on all symbols we need to load both. I hope this makes sense. My other patch D66791 implements support for minidebuginfo, that's why I need this change.

* [LLDB] Do not try to canonicalize gethostname() resultDavid Zarzycki2019-09-111-12/+1
| | | | | | | | | | | | | | | | This code is trying too hard and failing. Either the result of gethostname() is canonical or it is not. If it is not, then trying to canonicalize it is – for various reasons – a lost cause. For example, a given machine might have multiple network interfaces with multiple addresses per interface, each with a different canonical name. Separably, the result of HostInfoPosix::GetHostname() and latency thereof shouldn't depend on whether networking is up or down or what network the machine happened to be attached to at any given moment (like a laptop that travels between work and home). https://reviews.llvm.org/D67230 llvm-svn: 371596

* Implement DW_OP_convertAdrian Prantl2019-09-107-32/+423
| | | | | | | | | | | | | | | | | | | | | | This patch adds basic support for DW_OP_convert[1] for integer types. Recent versions of LLVM's optimizer may insert this opcode into DWARF expressions. DW_OP_convert is effectively a type cast operation that takes a reference to a base type DIE (or zero) and then casts the value at the top of the DWARF stack to that type. Internally this works by changing the bit size of the APInt that is used as backing storage for LLDB's DWARF stack. I managed to write a unit test for this by implementing a mock YAML object file / module that takes debug info sections in yaml2obj format.

* [Symbol] Give ClangASTContext a PersistentExpressionState instead of a ↵Alex Langford2019-09-093-8/+6
| | | | | | | | | | | | | | | ClangPersistentVariables ClangASTContext doesn't use m_persistent_variables in a way specific to ClangPersistentVariables. Therefore, it should hold a unique pointer to PersistentExpressionState instead of a ClangPersistentVariablesUP. This also prevents you from pulling in a plugin header when including ClangASTContext.h Doing this exposed an implicit dependency in ObjCLanguage that was corrected by including ClangModulesDeclVendor.h llvm-svn: 371470

* Fix ELF core file memory reading for PT_LOAD program headers with no p_fileszGreg Clayton2019-09-092-9/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this fix, ELF files might contain PT_LOAD program headers that had a valid p_vaddr, and a valid file p_offset, but the p_filesz would be zero.

Prior to this fix if users tried to read memory from one of these addresses like 0x8048000, they would end up incorrectly reading from the next memory region that actually had a p_filesz which would be 0x00000000f778c000 in this case. This fix correctly doesn't include program headers with zero p_filesz in the ProcessELFCore::m_core_aranges that is used to read memory. I found two cores files that have this same issue and added tests. Differential Revision: https://reviews.llvm.org/D67370 llvm-svn: 371457

* Long timeouts for the MacOSX SystemRuntime plugins under ASAN; else quick.Jason Molenda2019-09-074-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | In April via r357829, Adrian unified timeouts across lldb and set the default value high so that we wouldn't get timeouts on ASAN bots that were running under load. The library that the MacOSX SystemRuntime has functions that need to take a lock, and if that lock is held already, those functions will never complete; we're seeing the 15 second timeout being hit with inferiors that are doing a lot of enqueuing and dequeuing of libdispatch work items causing this deadlocking behavior. This patch reverts to a very short timeout for these SystemRuntime function calls, given the behavior of this library that they are calling into. When lldb is built with AddressSanitizer enabled, they will use the default 15 second timeout. tl;dr: this reverts to the previous timeouts for these SystemRuntime inf func calls. <rdar://problem/54538149> llvm-svn: 371280
* [test] Add a FIXME test for stop-command-source-on-errorJonas Devlieghere2019-09-063-0/+30
| | | | | | | | | | | | | | Modifying the interpreter settings is tricky because they don't take effect until we create a new command interpreter, which should be merely an implementation detail. This leads to confusing and unexpected scenarios. This adds a test cases with FIXMEs for some of the odd scenarios I encountered. I didn't XFAIL the test because I don't think there's a way to get an unexpected PASS if any of the commands succeeds and splitting up the file in multiple tests seems excessive. llvm-svn: 371259
