We want all ports to opt into extra warnings as the default compiler
settings lets a lot slide. Opt all the ports that haven't already in
to the warning system. None of them build with -Werror, so disable
that by default. Hopefully someone finds these important enough to
start fixing at some point.
Since we require C11 now, we can assume many headers exist, and
clean up all of the conditional includes. It's not like any of
this code actually accounted for the headers not existing, just
whether we could include them.
The strings.h cleanup is a little nuanced: it isn't in C11, but
every use of it in the codebase will include strings.h only if
string.h doesn't exist. Since we now assume the C11 string.h
exists, we'll never include strings.h, so we can delete it.
With GDB requiring a C++11 compiler now, this hopefully shouldn't
be a big deal. It's been 10 years since C11 came out, so should
be plenty of time to upgrade.
This will allow us to start cleaning up random header logic and
many of our non-standard custom types.
We don't want arch-specific entries in the common ChangeLog files.
Most arches do this already, so clean up the recent additions, and
move some older entries down to help avoid confusing newcomers.

gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.
I noticed a little diff when re-generating the configure file in this
directory.
sim/ChangeLog:
* bpf/configure: Re-generate.
Change-Id: Ieb26be2cc1be8108d4b08387255f45b57f288171
The div and mod eBPF instructions are unsigned, but the semantic
specification for the simulator incorrectly used signed operators.
Correct them to unsigned versions, and correct the ALU tests in
the simulator (which incorrectly assumed signed semantics).
Tested in bpf-unknown-none.
cpu/ChangeLog:
2020-09-08 David Faust <david.faust@oracle.com>
* bpf.cpu (define-alu-instructions): Correct semantic operators
for div, mod to unsigned versions.
sim/ChangeLog:
2020-09-08 David Faust <david.faust@oracle.com>
* bpf/sem-be.c: Regenerate.
* bpf/sem-le.c: Likewise.
sim/testsuite/ChangeLog:
2020-09-08 David Faust <david.faust@oracle.com>
* sim/bpf/alu.s: Correct div and mod tests.
* sim/bpf/alu32.s: Likewise.
This patch fixes the following problems:
- Missing includes in several files leading to implicit function
declarations.
- Missing prototype for bpf_trace_printk in bpf-helpers.h
- The simulator bitsize was set to 32 bits, causing truncation of
the program counter.
Tested in bpf-unknown-none.
sim/ChangeLog:
2020-09-03 Jose E. Marchesi <jose.marchesi@oracle.com>
