I'd like to enable the -Wmissing-declarations warning. However, it
warns for every _initialize function, for example:
CXX dcache.o
/home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
/home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
_initialize_dcache (void)
^~~~~~~~~~~~~~~~~~
The only practical way forward I found is to add back the declarations,
which were removed by this commit:
commit 481695ed5f
Author: John Baldwin <jhb@FreeBSD.org>
Date: Sat Sep 9 11:02:37 2017 -0700
Remove unnecessary function prototypes.
I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

/* This module provides support for "Ravenscar" tasks (Ada) when
|
|
debugging on bare-metal targets.
|
|
|
|
The typical situation is when debugging a bare-metal target over
|
|
the remote protocol. In that situation, the system does not know
|
|
about high-level concepts such as threads, only about some code
|
|
running on one or more CPUs. And since the remote protocol does not
|
|
provide any handling for CPUs, the de facto standard for handling
|
|
them is to have one thread per CPU, where the thread's ptid has
|
|
its lwp field set to the CPU number (eg: 1 for the first CPU,
|
|
2 for the second one, etc). This module will make that assumption.
|
|
|
|
This module then creates and maintains the list of threads based
|
|
on the list of Ada tasks, with one thread per Ada task. The convention
|
|
is that threads corresponding to the CPUs (see assumption above)
|
|
have a ptid_t of the form (PID, LWP, 0), while threads corresponding
|
|
to our Ada tasks have a ptid_t of the form (PID, 0, TID) where TID
|
|
is the Ada task's ID as extracted from Ada runtime information.
|
|
|
|
Switching to a given Ada task (or its underlying thread) is performed
|
|
by fetching the registers of that task from the memory area where
|
|
the registers were saved. For any of the other operations, the
|
|
operation is performed by first finding the CPU on which the task
|
|
is running, switching to its corresponding ptid, and then performing
|
|
the operation on that ptid using the target beneath us. */
