Yeah, I assumed that I could redefine my “r” alias to include this, but there is no flag to process launch.

This doesn’t appear to work, I tried both lldb and in a debug session.  I’m starting lldb with “lldb -- swiftc … “ if that matters.

(lldb) break set -n _dyld_start --skip-prologue 0 -s dyld
Breakpoint 1: where = dyld`_dyld_start, address = 0x0000000000001000
(lldb) b com add -o continue
Breakpoint 2: no locations (pending).
WARNING:  Unable to resolve breakpoint to any actual locations.

I’m not :(
