This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.
|
|
Use the new target-newlib-syscall module. This is needed to merge all
the architectures into a single build, and sh has a custom syscall
table for its newlib/libgloss port.
|
|
With most of the warnings fixed in interp.c, we can enable -Werror
here too now. There are some -Wmaybe-uninitialized warnings still
lurking that look legitimate, but we don't flag those are fatal,
and I don't have the expertise to dive into each opcode to figure
out the right way to clean them up.
|
|
These rules don't depend on the target compiler settings, so hoist
the build logic up to the common builds for better parallelization.
|
|
Only one file in here still generates warnings, so reduce the -Werror
disable to that alone now that we require GNU make and can set variables
on a per-object basis.
|
|
Update the gencode rules to use the silent build helpers.
|
|
For the ports that still don't build with -Werror, rather than disable
the flag at configure time, do it at make time. This will allow us to
unify these tests in the common sim configure script.
|
|
Some spots in the sim build used manual dependencies, and some spots
did a compilation by hand but did not use the automatic dependency
tracking code. This patch fixes these spots.
I didn't touch ppc, because it doesn't use the common Makefile code.
I also didn't touch objects that are for the build machine, because
automatic dependencies don't work for those.

Rather than hand duplicate the syscall table, switch to the common
nltvals framework. We have to tweak the constant names, but we get
everything else for free. I made sure the constants have the same
values before & after too :).
|
|
These use the same pattern as seen in the opcodes/ dir and in automake
in general (ish). This helps simplify the boilerplate for building and
linking build-time code, and fixes some inconsistency in flag usage.
For rules that were compiling+linking in a single step, split them into
separate steps so we can apply the correct set of options. This matches
automake behavior too.

This commits the result of running gdb/copyright.py as per our Start
of New Year procedure...

Update copyright year range in copyright header of all GDB files.

gdb/ChangeLog:
Update copyright year range in all GDB files.
|
|
This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

Update copyright year range in all GDB files.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.

Pretty much all targets are using this module already, so add it to the
common list of objects. The only oddball out here is cris and that's
because it supports loading via an offset for all the phdrs. We drop
support for that.
|
|
Now that all arches (for the most part) have moved over, move sim-stop.o,
sim-reason.o, and sim-reg.o to the common object list and out of all the
arch ports.
|
|
Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the
cpu state is multicore, and the STATE_CPU defines match, we can move
it all to the common code.
|
|
This makes these two objects available to all sims by default.
|
|
A lot of cpu state is stored in global variables, as is memory handling.
The sim_size support needs unwinding at some point. But at least this
is an improvement on the status quo.
|
|
The build line was missing the normal BUILD_xxx flags. Once we added
that, we get warnings that weren't shown before. As we fix those, we
notice that the -d option segfaults because it tries to write readonly
memory. Fix that too as part of the const/prototype clean up.
|
|
We want people to stop using the run.c frontend, but it's hard to notice
when it's still set as the default. Lets flip things so nrun.c is the
default, and users of run.c will get an error by default. We turn that
error into a warning for existing sims so we don't break them -- this is
mostly meant for people starting new ports.

gdb/ChangeLog:
Update year range in copyright notice of all files.
|
|
|

Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
