https://discourse.llvm.org/t/running-lldb-in-a-container/76801/4 found that the obvious way to use this variable doesn't work, despite what our docs and examples say. Perhaps in the past it did but now you need to use ";" as a separator to make sure the final command line works properly. For example "-A foo" becomes "-A foo" when python goes to run the runner script. The script sees this as one command line element, not two. What you actually want is "-A;foo" which we convert to "-A" "foo" which the script sees as one option and one value for that option. The "Script:" printout from dotest is misleading here because it does `" ".join(cmd)` so it looks like it's ok but in fact it's not. I'm not changing that format though because printing the command as a Python list is not useful outside of this specific situation. >From 424c48e1b53ebfe1119ad09b39f6730d127b254e Mon Sep 17 00:00:00 2001 From: David Spickett <david.spick...@linaro.org> Date: Wed, 17 Apr 2024 09:49:37 +0000 Subject: [PATCH] [lldb] Correct documentation of LLDB_TEST_USER_ARGS https://discourse.llvm.org/t/running-lldb-in-a-container/76801/4 found that the obvious way to use this variable doesn't work, despite what our docs and examples say.
