* Reapply "Make Scalar::GetValue more consistent"Pavel Labath2016-09-021-1/+0
| | | | | | | | this is a resubmission of r280476. The problem with the original commit was that it was printing out all numbers as signed, which was wrong for unsigned numbers with the MSB set. Fix that and add a unit test covering that case. llvm-svn: 280480
* Revert "Make Scalar::GetValue more consistent"Pavel Labath2016-09-021-0/+1
| | | | | | | This reverts commit r280476 as it breaks several tests on i386. I was fixing an 32-bit breakage, and I did not run the 32-bit test suite before submitting, oops. llvm-svn: 280478
* Make Scalar::GetValue more consistentPavel Labath2016-09-021-1/+0
| | | | | | | | | | | | | | | | | | | | | | | Summary: It seems the original intention of the function was printing signed values in decimal format, and unsigned values in hex (without the leading "0x"). However, signed and unsigned long were exchanged, which lead to amusing test failures in TestMemoryFind.py. Instead of just switching the two, I think we should just print everything in decimal here, as the current behaviour is very confusing (especially when one does not request printing of types). Nothing seems to depend on this behaviour except and we already have a way for the user to request the format he wants when printing values for most commands (which presumably does not go through this function). I also add a unit tests for the function in question. Reviewers: clayborg, granata.enrico Subscribers: lldb-commits Differential Revision: https://reviews.llvm.org/D24126 llvm-svn: 280476

| | | | | | | | the test fails for a very prosaic reason: `(const char *)0x1000` returns "4096" on x86_64 and "1000" (without the "0x") on i386. I haven't tried other 32-bit arches, but I am guessing the behaviour is the same. XFAIL until someone can get a chance to look at this. llvm-svn: 280344

* Delete Host/windows/win32.hZachary Turner2016-08-091-7/+7
| | | | | | | | | | | | | | | | | | | It's always hard to remember when to include this file, and when you do include it it's hard to remember what preprocessor check it needs to be behind, and then you further have to remember whether it's windows.h or win32.h which you need to include. This patch changes the name to PosixApi.h, which is more appropriately named, and makes it independent of any preprocessor setting. There's still the issue of people not knowing when to include this, because there's not a well-defined set of things it exposes other than "whatever is missing on Windows", but at least this should make it less painful to fix when problems arise. This patch depends on LLVM revision r278170. llvm-svn: 278177

* Add/fix support for i386 elf core filesDimitar Vlahovski2016-07-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: There were places in the code, assuming(hardcoding) offsets and types that were only valid for the x86_64 elf core file format. The NT_PRSTATUS and NT_PRPSINFO structures are with the 64 bit layout. I have reused them and parse i386 files manually, and fill them in the same struct. Also added some error handling during parsing that checks if the available bytes in the buffer are enough to fill the structures. The i386 core file test case now passes. For reference on the structures layout, I generally used the source of binutils (bfd, readelf) Bug: https://llvm.org/bugs/show_bug.cgi?id=26947 Reviewers: labath Subscribers: lldb-commits Differential Revision: https://reviews.llvm.org/D22917 llvm-svn: 277140

* Breakup TestConcurrentEvents.py into separate test subdirs per test methodTodd Fiala2016-07-2271-526/+1123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change breaks up the monolithic TestConcurrentEvents.py into a separate subdir per test method. This allows them to run concurrently, reduces the chance of a timeout occurring during normal operation, and allows us to home in on any test methods that may be locking up. This is step one in the process of squashing timeouts in these test methods. The reason for breaking each test method into its own file is to make it very clear to us if there are a subset of the tests that do in fact lock up frequently. This will limit how much hunting we need to do to recreate it. The reason for putting each file in a separate subdirectory is so that our concurrent test runner can run multiple test files at the same time. The unit of serialization in the LLDB test suite is the test directory, so moving them into separate directories enables the test runner to do more at the same time. This change introduces usage of VPATH from gnu make. I use that to facilitate keeping a single copy of the main.cpp in the parent concurrent_events directory. Initially I had tried specifying the source file as ../main.cpp, but our current makefile rules get confused by that and then also build the output into the parent directory, which defeats the ability to run each of the test methods concurrently. In the event that not all systems support VPATH, I can do a bit of surgery on the Makefile rules and attempt to make it smarter with regards to relative paths to source files used in the build. llvm-svn: 276478

* Fix for PrintStackTracesRavitheja Addepally2016-07-073-0/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The issue arises due to the wrong unwinder used for the first stack frame, where the default unwinder returns erroneous frame whereas the fallback would have given the correct frame had it been used. The following fix consists of two parts -> 1) The first part changes the unwinding strategy, earlier the default unwinder was used to get 2 more stack frames and if it failed a fallback unwinder was used. Now we try to obtain as many frames (max 10) as we can get from default unwinder and also fallback unwinder and use the one that gives more number of frames. 2) Normally unwindplans are assosciated with functions and the row to be used is obtained from the offset (obtained from the low_pc of the function symbol). Sometimes it may occur that the unwindplan is assosciated to the complete Elf section in which case the offset calculation would be wrong as the debugger uses the same offset originally obtained from the function symbol. Hence this offset is recalculated. Reviewers: tberghammer, lldb-commits, labath, jasonmolenda Subscribers: jingham Differential Revision: http://reviews.llvm.org/D21221 llvm-svn: 274750
* Implement GetMemoryRegions() for Linux and Mac OSX core files.Howard Hellyer2016-07-071-7/+68
| | | | | | | | | | | | | | | Summary: This patch fills in the implementation of GetMemoryRegions() on the Linux and Mac OS core file implementations of lldb_private::Process (ProcessElfCore::GetMemoryRegions and ProcessMachCore::GetMemoryRegions.) The GetMemoryRegions API was added under: http://reviews.llvm.org/D20565 The patch re-uses the m_core_range_infos list that was recently added to implement GetMemoryRegionInfo in both ProcessElfCore and ProcessMachCore to ensure the returned regions match the regions returned by Process::GetMemoryRegionInfo(addr_t load_addr, MemoryRegionInfo &region_info).

* fix invalid assumption about the executable module in Target::Install()Todd Fiala2016-06-271-0/+1
| | | | | | | | | | | | | | | Target::Install() was assuming the module at index 0 was the executable. This is often true, but not guaranteed to be the case. The TestInferiorChanged.py test highlighted this when run against iOS. After the binary is replaced in the middle of the test, it becomes the last module in the list. The rest of the Target::Install() logic then clobbers the executable file by using whatever happens to be the first module in the target module list. This change also marks the TestInferiorChanged.py test as a no-debug-info test. llvm-svn: 273960

* Make lldbinline.py regenerate the Makefile each time it builds.Sean Callanan2016-06-074-11/+31
| | | | | | | | | | | | | If a lldbinline test's source file changed language, then the Makefile wasn't updated. This was a problem if the Makefile was checked into the repository. Now lldbinline.py always regenerates the Makefile and asserts if the newly-generated version is not the same as the one already there. This ensures that the repository will never be out of date without a buildbot failing. http://reviews.llvm.org/D21032 llvm-svn: 272024
* [tsan] Prefer mangled name looking up variable declaration for racy addressDevin Coughlin2016-06-013-0/+98
| | | | | | | | | | | | | | | | For Thread Sanitizer reports, LLDB tries to find a global variable declaration corresponding to the racy address in order to provide a filename and line number. This commit changes the lookup of the variable to use the mangled name for lookup and fall back to the demangled version if unavailable. This is needed to report locations of races on Swift global variables. I've also added a test to make sure we look up C++ globals correctly. rdar://problem/26459401 Differential Revision: http://reviews.llvm.org/D20760 llvm-svn: 271433
