Rewrite an inline test as an API test, to be a little easier to debug, and add some additional checks that we're in the inlined test1, then step and we are now in the inlined test2 functions. >From c02e38e5ef017a966ef80000b94a56e394309462 Mon Sep 17 00:00:00 2001 From: Jason Molenda <jmole...@apple.com> Date: Wed, 5 Jun 2024 15:27:23 -0700 Subject: [PATCH] [lldb] [NFC] Rewrite TestRedefinitionsInInlines.py as an API test Rewrite an inline test as an API test, to be a little easier to debug, and add some additional checks that we're in the inlined test1, then step and we are now in the inlined test2 functions. --- lldb/test/API/lang/c/inlines/Makefile | 3 + .../c/inlines/TestRedefinitionsInInlines.py | 73 +++++++++++++++---- lldb/test/API/lang/c/inlines/main.c | 23 +++--- 3 files changed, 74 insertions(+), 25 deletions(-) create mode 100644 lldb/test/API/lang/c/inlines/Makefile diff --git a/lldb/test/API/lang/c/inlines/Makefile b/lldb/test/API/lang/c/inlines/Makefile new file mode 100644 index 0000000000000..f9555f92be8cd --- /dev/null +++ b/lldb/test/API/lang/c/inlines/Makefile @@ -0,0 +1,3 @@ +C_SOURCES := main.c + +include Makefile.rules diff --git a/lldb/test/API/lang/c/inlines/TestRedefinitionsInInlines.py b/lldb/test/API/lang/c/inlines/TestRedefinitionsInInlines.py index 024b9dad9b0fb..d48f88ad7d563 100644 --- a/lldb/test/API/lang/c/inlines/TestRedefinitionsInInlines.py +++ b/lldb/test/API/lang/c/inlines/TestRedefinitionsInInlines.py @@ -1,14 +1,61 @@ -from lldbsuite.test import lldbinline -from lldbsuite.test import decorators - -lldbinline.MakeInlineTest( - __file__, - globals(), - [ - decorators.expectedFailureAll( - compiler="clang", - compiler_version=["<", "3.5"], - bugnumber="llvm.org/pr27845", +"""Test that inlined argument variables have their correct location in debuginfo""" + +import lldb +from lldbsuite.test.decorators import * +from lldbsuite.test.lldbtest import * +from lldbsuite.test import lldbutil + + +class TestRedefinitionsInInlines(TestBase): + + # https://github.com/llvm/llvm-project/issues/28219 + @skipIf(compiler="clang", compiler_version=["<", "3.5"]) + def test(self): + self.source = "main.c" + self.build() + (target, process, thread, bp1) = lldbutil.run_to_source_breakpoint( + self, "first breakpoint", lldb.SBFileSpec(self.source, False) ) - ], -) + + bp2 = target.BreakpointCreateBySourceRegex( + "second breakpoint", lldb.SBFileSpec(self.source, False) + ) + bp3 = target.BreakpointCreateBySourceRegex( + "third breakpoint", lldb.SBFileSpec(self.source, False) + ) + + # When called from main(), test2 is passed in the value of 42 in 'b' + self.expect("expression b", DATA_TYPES_DISPLAYED_CORRECTLY, substrs=["42"]) + + process.Continue() + + self.assertState(process.GetState(), lldb.eStateStopped) + thread = lldbutil.get_stopped_thread(process, lldb.eStopReasonBreakpoint) + self.assertIsNotNone(thread) + bp_id = thread.GetStopReasonDataAtIndex(0) + self.assertEqual(bp_id, bp2.GetID()) + + self.expect("expression b", DATA_TYPES_DISPLAYED_CORRECTLY, substrs=["42"]) + self.expect("expression c", DATA_TYPES_DISPLAYED_CORRECTLY, substrs=["84"]) + + process.Continue() + + # Now we're in test1(), and the first thing it does is call test2(24).
