Classification:Feature (New) Reproducible:Yes
 
Summary:

While debugging, I'll often use breakpoint actions or the debugger REPL to return early from functions/methods with a particular return value. Under GDB, this is possible by setting a continuing breakpoint with a breakpoint action, where the action is `return <expr>`. There is no such `return` command available under LLDB.

There was some discussion of a `frame-return` or `thread-return` on the LLDB-dev mailing list in July 2011, however I'm not sure if the patch was ever accepted. Email thread starts here:

Thanks!

Steps to Reproduce:

Expected Results:

Find an equivalent.

Actual Results:

Dont' find an equivalent :-)

Regression:

This is a regression, because something that was previously possible under GDB is no longer possible under LLDB.

Notes:

N/A
