TestThreadStates::test_process_state expects a signal stop reason after "process interrupt", but the trap from the single step used to step off the breakpoint is reported as a trace stop. It is already skipped on Linux and Darwin for the same reason. TestBuiltinDebugTrap expects to continue past __builtin_debugtrap, but on WebAssembly that lowers to the unreachable instruction, a fatal trap that cannot be resumed. >From ebd5ea78ac8ed7d5f785b01d2b926ab1d5260b66 Mon Sep 17 00:00:00 2001 From: Jonas Devlieghere <[email protected]> Date: Wed, 22 Jul 2026 06:51:45 -0700 Subject: [PATCH] [lldb][test] Skip stop-reason tests unsupported on WebAssembly TestThreadStates::test_process_state expects a signal stop reason after "process interrupt", but the trap from the single step used to step off the breakpoint is reported as a trace stop.
