From d9442afba1bd65fd0b5c93b67922eaed923445e2 Mon Sep 17 00:00:00 2001 From: Raphael Isemann Date: Tue, 10 Sep 2019 12:04:04 +0000 Subject: [lldb] Readd missing functionalities/breakpoint tests It seems when I restructured the test folders the functionalities/breakpoint was deleted. This just reverts this change and re-adds the tests. llvm-svn: 371512 --- .../breakpoint/debugbreak/TestDebugBreak.py | 58 ++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 lldb/packages/Python/lldbsuite/test/functionalities/breakpoint/debugbreak/TestDebugBreak.py (limited to 'lldb/packages/Python/lldbsuite/test/functionalities/breakpoint/debugbreak/TestDebugBreak.py') diff --git a/lldb/packages/Python/lldbsuite/test/functionalities/breakpoint/debugbreak/TestDebugBreak.py b/lldb/packages/Python/lldbsuite/test/functionalities/breakpoint/debugbreak/TestDebugBreak.py new file mode 100644 index 00000000000..f8d5704d990 --- /dev/null +++ b/lldb/packages/Python/lldbsuite/test/functionalities/breakpoint/debugbreak/TestDebugBreak.py @@ -0,0 +1,58 @@ +""" +Test embedded breakpoints, like `asm int 3;` in x86 or or `__debugbreak` on Windows. +""" + +from __future__ import print_function + +import lldb +from lldbsuite.test.decorators import * +from lldbsuite.test.lldbtest import * +from lldbsuite.test import lldbutil + + +class DebugBreakTestCase(TestBase): + + mydir = TestBase.compute_mydir(__file__) + + @skipIf(archs=no_match(["i386", "i686", "x86_64"])) + @no_debug_info_test + def test_asm_int_3(self): + """Test that intrinsics like `__debugbreak();` and `asm {"int3"}` are treated like breakpoints.""" + self.build() + exe = self.getBuildArtifact("a.out") + + # Run the program. + target = self.dbg.CreateTarget(exe) + process = target.LaunchSimple( + None, None, self.get_process_working_directory()) + + # We've hit the first stop, so grab the frame. + self.assertEqual(process.GetState(), lldb.eStateStopped) + stop_reason = lldb.eStopReasonException if (lldbplatformutil.getPlatform( + ) == "windows" or lldbplatformutil.getPlatform() == "macosx") else lldb.eStopReasonSignal + thread = lldbutil.get_stopped_thread(process, stop_reason) + self.assertIsNotNone( + thread, "Unable to find thread stopped at the __debugbreak()") + frame = thread.GetFrameAtIndex(0) + + # We should be in funciton 'bar'. + self.assertTrue(frame.IsValid()) + function_name = frame.GetFunctionName() + self.assertTrue('bar' in function_name, + "Unexpected function name {}".format(function_name)) + + # We should be able to evaluate the parameter foo. + value = frame.EvaluateExpression('*foo') + self.assertEqual(value.GetValueAsSigned(), 42) + + # The counter should be 1 at the first stop and increase by 2 for each + # subsequent stop. + counter = 1 + while counter < 20: + value = frame.EvaluateExpression('count') + self.assertEqual(value.GetValueAsSigned(), counter) + counter += 2 + process.Continue() + + # The inferior should exit after the last iteration. + self.assertEqual(process.GetState(), lldb.eStateExited) -- cgit v1.2.3
