Jim says:
lldb has a -Q or --source-quietly option, which supposedly does:
--source-quietly Tells the debugger to execute this one-line lldb command before any file has been loaded.
That seems like a weird description, since we don't generally use source for one line entries, but anyway, let's try it:
> $LLDB_LLVM/clean-mono/build/Debug/bin/lldb -Q "script print('I should be quiet')" a.out -O "script print('I should be before')" -o "script print('I should be after')"
(lldb) script print('I should be before')
I should be before
(lldb) target create "script print('I should be quiet')"
error: unable to find executable for 'script print('I should be quiet')'
That was weird. The first real -O gets sourced but not quietly, then the argument to the -Q gets treated as the target.
> $LLDB_LLVM/clean-mono/build/Debug/bin/lldb -Q a.out -O "script print('I should be before')" -o "script print('I should be after')"
(lldb) script print('I should be before')
I should be before
(lldb) target create "a.out"
Current executable set to '/tmp/a.out' (x86_64).
(lldb) script print('I should be after')
I should be after
Well, that's a little better, but the -Q option seems to have done nothing.
---
This fixes the description of --source-quietly, as well as causing it
to actually suppress echoing while executing the initialization
commands.
