More thoughts:
I've read http://lldb.llvm.org/tutorial.html in more depth now ;-)
(appreciating that the debugger and the inferior require separate stdins.)
I see there's an option, "--no-stdin", proposing to mitigate the issue I
found
"If you attach to a process, or launch a process with the "|--no-stdin|"
option, the command interpreter is always available to enter commands.
This might be a little disconcerting to gdb users when always have an
|(lldb)| prompt. This allows you to set a breakpoint, etc without having
to explicitly interrupt the program you are debugging:
|(lldb) process continue
(lldb) breakpoint set --name stop_here |
"
However, it seems that --no-stdin is not present as a "process launch"
option anymore, but rather we have "--no-stdio". (Perhaps a typo,
somewhere?). I tried this option:
(lldb) process launch -s --no-stdio
Process 2344 launching
Process 2344 launched: './forever' (x86_64)
Process 2344 stopped
* thread #1: tid = 2344, 0x0000003675a011f0, name = 'forever', stop
reason = trace
frame #0: 0x0000003675a011f0
-> 0x3675a011f0: movq %rsp, %rdi
0x3675a011f3: callq 0x3675a046e0
0x3675a011f8: movq %rax, %r12
0x3675a011fb: movl 0x21eb97(%rip), %eax
(lldb) process continue
Process 2344 resuming
The interpreter prompt still fails to appear, so I still think I'm
either seeing a bug, or that the documentation is incomplete as to
describing how to run lldb such that the command interpreter, is always
available when the inferior is running.
