From c152f18b0c0436891eeb172700a4b7b84e5a0a1c Mon Sep 17 00:00:00 2001 From: Jim Ingham Date: Wed, 30 Oct 2024 12:41:52 -0700 Subject: [PATCH 1/2] Skip one inline stepping test for arm-ubuntu. The test is currently passing everywhere but this 32-bit arm ubuntu bot. I don't have an easy way to debug this, so I'm skipping the test on that platform till we get a chance to figure this out. --- .../API/functionalities/inline-stepping/TestInlineStepping.py | 2 ++ 1 file changed, 2 insertions(+) diff --git a/lldb/test/API/functionalities/inline-stepping/TestInlineStepping.py b/lldb/test/API/functionalities/inline-stepping/TestInlineStepping.py index f52e0f0fd5bcf..d3d00bca36b92 100644 --- a/lldb/test/API/functionalities/inline-stepping/TestInlineStepping.py +++ b/lldb/test/API/functionalities/inline-stepping/TestInlineStepping.py @@ -14,6 +14,8 @@ class TestInlineStepping(TestBase): compiler="icc", bugnumber="# Not really a bug.
