    runtime: support for debugger function calls · c5ed10f3
    Austin Clements authored
    This adds a mechanism for debuggers to safely inject calls to Go
    functions on amd64. Debuggers must participate in a protocol with the
    runtime, and need to know how to lay out a call frame, but the runtime
    support takes care of the details of handling live pointers in
    registers, stack growth, and detecting the trickier conditions when it
    is unsafe to inject a user function call.
    
    Fixes #21678.
    Updates derekparker/delve#119.
