All patches for thisgeneric REPL code therefore also only have tests downstream which is clearly nota good situation.This patch implements a basic C language REPL on top of LLDB's REPL framework.Beside implementing the REPL interface and hooking it up into the pluginmanager, the only other small part of this patch is making the `--language` flagof the expression command compatible with the `--repl` flag. The `--repl` flaguses the value of `--language` to see which REPL should be started, but rightnow the `--language` flag is only available in OptionGroups 1 and 2, but not inOptionGroup 3 where the `--repl` flag is declared.The REPL currently can currently only start if a running target exists. I'll addthe 'create and run a dummy executable' logic from Swift (which is requires whendoing `lldb --repl`) when I have time to translate all this logic to somethingthat will work with Clang.I should point out that the REPL currently uses the C expression parser'sapproach to persistent variables where only result variables and the onesstarting with a '$' are transferred between expressions. I'll fix that in afollow up patch. Also the REPL currently doesn't work in a non-interactiveterminal. This seems to be fixed in the Swift fork, so I assume one of our manyREPL downstream changes addresses the issue.Reviewed By: JDevlieghereDifferential Revision: https://reviews.llvm.org/D87281 List of files: /llvm-project-15.0.7/lldb/test/API/repl/clang/Makefile Thu, 23 Sep 2021 17:13:50 +0000 Raphael Isemann <teemperor@gmail.com>
