* Fix whitespace in the python test suite.Raphael Isemann2018-07-271-1/+1
| | | | | | | | | | | | | Summary: The test suite has often unnecessary trailing whitespace, and sometimes unnecessary trailing lines or a missing final new line. This patch just strips trailing whitespace/lines and adds missing newlines at the end.

* [lldbsuite, windows] Don't crash LLDB when we try to retrieve a register on ↵Stella Stamenova2018-07-022-2/+3
| | | | | | | | | | | | | | | | Windows Summary: 1) When ReadRegister is called with a null register into on Windows, rather than crashing due to an access violation, simply return false. Not all registers and properties will be read or calculated correctly, but that is consistent with other platforms that also return false in that case 2) Update a couple of tests to reference pr37995 as their reason for failure since it is much more accurate. Support for floating point registers doesn't exist on Windows at all, rather than having issues.

* [test] Skip a test when using an out-of-tree debugserverVedant Kumar2018-03-081-0/+1
| | | | | | | | | | | | | | | | | | | | The test "test_fp_special_purpose_register_read" in TestRegisters.py fails on Darwin machines configured to use an out-of-tree debugserver. The error message is: 'register read ftag' returns expected result, got 'ftag = 0x80'. This indicates that the debugserver in use is too old. This commit introduces a decorator which can be used to skip tests which rely on having a just-built debugserver. This resolves the issue: $ ./bin/llvm-dotest -p TestRegisters.py -v 1 out of 617 test suites processed - TestRegisters.py Test Methods: 7 Success: 6 Skip: 1 ... llvm-svn: 327052
* Upstreaming avx512 register support in debugserver. These changesJason Molenda2018-03-063-19/+223
| | | | | | | | | | | | | | | | | | | were originally written by Chris Bieneman, they've undergone a number of changes since then. Also including the debugserver bridgeos support, another arm environment that runs Darwin akin to ios. These codepaths are activated when running in a bridgeos environment which we're not set up to test today. There's additional (small) lldb changes to handle bridgeos binaries that still need to be merged up. Tested on a darwin system with avx512 hardware and without. <rdar://problem/36424951> llvm-svn: 326756
* Compile the LLDB tests out-of-tree.Adrian Prantl2018-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This patch is the result of a discussion on lldb-dev, see http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for background. For each test (should be eventually: each test configuration) a separate build directory is created and we execute make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test In order to make this work all LLDB tests need to be updated to find the executable in the test build directory, since CWD still points at the test's source directory, which is a requirement for unittest2. Although we have done extensive testing, I'm expecting that this first attempt will break a few bots. Please DO NOT HESITATE TO REVERT this patch in order to get the bots green again. We will likely have to iterate on this some more. Differential Revision: https://reviews.llvm.org/D42281 llvm-svn: 323803

* Fix floating point register write on new x86 linux kernelsPavel Labath2017-11-281-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: New linux kernels (on systems that support the XSAVES instruction) will not update the inferior registers unless the corresponding flag in the XSAVE header is set. Normally this flag will be set in our image of the XSAVE area (since we obtained it from the kernel), but if the inferior has never used the corresponding register set, the respective flag can be clear. This fixes the issue by making sure we explicitly set the flags corresponding to the registers we modify. I don't try to precisely match the flags to set on each write, as the rules could get quite complicated -- I use a simpler over-approximation instead. This was already caught by test_fp_register_write, but that was only because the code that ran before main() did not use some of the register sets. Since nothing in this test relies on being stopped in main(), I modify the test to stop at the entry point instead, so we can be sure the inferior did not have a chance to access these registers.

* Switch "posix" to the new log channel registration mechanismPavel Labath2017-02-231-11/+5
| | | | | | | | | | | | | | | | | | Summary: This also removes magic rename code, which caused the channel to be called "linux" when built on a linux machine, and "freebsd" when built on a freebsd one, which seems unnecessary - registering a new channel is sufficiently simple now that if we wish to log something extremely os-specific, we can just create a new channel. None of the current categories seem very specific to one OS or another.

| | | | | | | | | | | | | | | | | Summary: This patch contains test for reading YMM Registers. The test basically contains an inferior that loads the ymm registers with a bit pattern and the python test executes register read to check if the bit pattern is correctly written in the registers. This test is repeated twice for each register with a different pattern for better sanity.

* *** This commit represents a complete reformatting of the LLDB source codeKate Stone2016-09-061-74/+141
| | | | | | | | | | | | | | | | | | | | | | | *** 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

* Remove `use_lldb_suite` from the package, and don't import it anymore.Zachary Turner2015-11-031-1/+1
| | | | | | | | | | | | | | | | This module was originally intended to be imported by top-level scripts to be able to find the LLDB packages and third party libraries. Packages themselves shouldn't need to import it, because by the time it gets into the package, the top-level script should have already done this. Indeed, it was just adding the same values to sys.path multiple times, so this patch is essentially no functional change. To make sure it doesn't get re-introduced, we also delete the `use_lldb_suite` module from `lldbsuite/test`, although the original copy still remains in `lldb/test` llvm-svn: 251963
* Tighten up sys.path, and use absolute imports everywhere.Zachary Turner2015-11-031-2/+2
| | | | | | | | | | | | | | | | | | | | For convenience, we had added the folder that dotest.py was in to sys.path, so that we could easily write things like `import lldbutil` from anywhere and any test. This introduces a subtle problem when using Python's package system, because when unittest2 imports a particular test suite, the test suite is detached from the package. Thus, writing "import lldbutil" from dotest imports it as part of the package, and writing the same line from a test does a fresh import since the importing module was not part of the same package. The real way to fix this is to use absolute imports everywhere. Instead of writing "import lldbutil", we need to write "import lldbsuite.test.util". This patch fixes up that and all other similar cases, and additionally removes the script directory from sys.path to ensure that this can't happen again. llvm-svn: 251886
* Move lldb/test to lldb/packages/Python/lldbsuite/test.Zachary Turner2015-10-284-0/+455
This is the conclusion of an effort to get LLDB's Python code structured into a bona-fide Python package. This has a number of benefits, but most notably the ability to more easily share Python code between different but related pieces of LLDB's Python infrastructure (for example, `scripts` can now share code with `test`). llvm-svn: 251532
