# Benefit This patch fixes: 1. After `platform select ios-simulator`, `platform process list` will now print processes which are running in the iOS simulator. Previously, no process will be listed. 2. After `platform select ios-simulator`, `platform attach --name <name>` will succeed. Previously, it will error out saying no process is found. # Several bugs that is being fixed 1. During the process listing, add `aarch64` to the list of CPU types for which iOS simulators are checked for. 2. Given a candidate process, when checking for simulators, the original code will find the desired environment variable (`SIMULATOR_UDID`) and set the OS to iOS, but then the immediate next environment variable will set it back to macOS. 3. For processes running on simulator, set the triple's `Environment` to `Simulator`, so that such processes can pass the filtering [in this line](https://fburl.com/8nivnrjx). The original code leave it as the default `UnknownEnvironment`. # Manual test **With this patch:** ``` royshi-mac-home ~/public_llvm/build % bin/lldb (lldb) platform select ios-simulator (lldb) platform process list 240 matching processes were found on "ios-simulator" PID PARENT USER TRIPLE NAME ====== ====== ========== ============================== ============================ 40511 28844 royshi arm64-apple-ios-simulator FocusPlayground // my toy iOS app running on simulator ... // omit 28844 1 royshi arm64-apple-ios-simulator launchd_sim (lldb) process attach --name FocusPlayground Process 40511 stopped * thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP frame #0: 0x0000000104e3cb70 libsystem_kernel.dylib`mach_msg2_trap + 8 libsystem_kernel.dylib`mach_msg2_trap: -> 0x104e3cb70 <+8>: ret ... // omit ``` **Without this patch:** ``` $ bin/lldb (lldb) platform select ios-simulator (lldb) platform process list error: no processes were found on the "ios-simulator" platform (lldb) process attach --name FocusPlayground error: attach failed: could not find a process named FocusPlayground ``` # Unittest See PR.
