[PATCH] D96033: [clang-repl] Land initial infrastructure for incremental parsing

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

To be clear, what I'm trying to say is that — absent consensus that it's a major architecture shift is appropriate — we need to consider what functionality is reasonably achievable without it.  I'm sure that covers most of what you're trying to do; it just may not include everything.

One of the fortunate things about working in a REPL is that many ABI considerations go completely out the window.  The most important of those is the abstract need for symbol-matching; that is, there's practically no reason why a C REPL needs to use the simple C symbol mangling, because nobody expects code written outside the REPL to link up with user-entered declarations.  So we can be quite aggressive about how we emit declarations "behind the scenes"; C mode really just means C's user-level semantics, calling convention, and type layout, but not any of C's ordinary interoperation/compatibility requirements.
