 [lldb] Sink StreamFile into lldbHost 2023-08-10T00:17:18+00:00 Alex Langford alangford@apple.com 2023-08-09T00:18:47+00:00 f2d32ddcec82c20582c6aa32558b82ca7c3d3c50 StreamFile subclasses Stream (from lldbUtility) and is backed by a File (from lldbHost). It does not depend on anything from lldbCore or any of its sibling libraries, so I think it makes sense for this to live in lldbHost instead. Differential Revision: https://reviews.llvm.org/D157460
