The major reason this header was needed, bfd_default_set_arch_mach,
has now moved to bfd.h.

Rather than stuffing the command line with a bunch of -D flags, start
moving things to config.h which is managed by autoheader. This makes
the makefile a bit simpler and the build output tighter, and it makes
the migration to automake easier as there are fewer vars to juggle.
We'll want to move the other options out too, but it'll take more work.
This was imported from the ppc sim, but that was only used to control
a single file, and that is already governed by the hw models. There's
no need to have a sep configure option here, especially since none of
the other sims are using it. Even when the code is enabled, there's
no runtime overhead.
Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in
order to make the configure flag available. There's no real reason
to not allow this flag for all ports, so move it to the common sim
macro. This way we get standard behavior across all ports too.
Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order
to make the configure flag available, which none of them do. There's
no real reason to not allow this flag for all ports, so move it to the
common sim macro. This way we get standard behavior across all ports.
We don't have alternative nltvals.def files, so always symlinking
the targ-vals.def file to it doesn't gain us anything. It does
make the build more complicated though and a pain to convert to
something newer (like automake). Drop the symlinking entirely.
In the future, we'll want to explode this file anyways into the
respective arch dirs so things can be selected dynamically at
runtime, so it's not like we'll be bringing this back.
Currently ports have to call SIM_AC_OPTION_INLINE explicitly in order
to make the configure flag available. There's no real reason to not
allow this flag for all ports, so move it to the common sim macro.
This way we get standard behavior across all ports too.
These options were never exposed for most sims (just the ppc one),
and they are really only useful on 32-bit x86 systems. Considering
modern systems tend to be 64-bit x86_64 and how well modern compilers
are at optimizing code, these have outlived their usefulness.
No other sub directory provides such a configuration option, so
drop it from the sim dir as well. This cleans up a good bit of
code in the process.
If people want to use custom flags for just the sim, they can
still run configure+make by hand in the sim subdir and use the
normal CFLAGS settings.
The common subdir sets up a cconfig.h file to hold checks for the common
code. In practice, most files still end up using config.h instead which
just leads to confusion.
Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON
so we can drop the cconfig.h file altogether. Now there is only a single
config.h file like normal.
The compiler/C library should produce reasonable code for htonl/ntohl,
and at least glibc tries pretty hard to always produce good code for
them. This logic only had support for 32-bit x86 systems anymore, and
it's unlikely people were even opting into this, so drop it all.
The --enable-sim-hostendian flag was purely so people had an escape route
for when cross-compiling. This is because historically, AC_C_BIGENDIAN
did not work in those cases. That was fixed a while ago though, so we can
require that macro everywhere now and simplify a good bit of code.
No arch is using this anymore, and we want all new ports using the
hardware framework instead. Punt WITH_DEVICES and the two callbacks
device_io_{read,write}_buffer.
We can also punt the tconfig.h file as no port is using it anymore.
This fixes in-tree builds that get confused by picking up the wrong
one (common/ vs <port>/) caused by commit ae7d0cac8c.
Any port that needs to set up a global define can use their own
sim-main.h file that they must provide regardless.
Rather than manually include tconfig.h when we think we'll need it (which
is error prone as it can define symbols we expect from config.h), have it
be included directly by config.h. Since we know we have to include that
header everywhere already, this will make sure tconfig.h isn't missed.
It should also be fine as tconfig.h is supposed to be simple and only set
up a few core defines for the target.
This allows us to stop symlinking it in place all the time and just use
it straight out of the respective source directory.
This should fix a build failure reported on x86_64-mingw32 by Daniel
Calcoen due to conflicting declarations of "open". This patch just
renames the static global in sim/rx/gdb-if.c into "rx_sim_is_open".
sim/rx/ChangeLog:
* gdb-if.c (open): Rename to...
(rx_sim_is_open): This. Replace all uses of "open" by uses of
"rx_sim_is_open" throughout.
Tested by rebuilding on x86_64-linux.
Directories that don't use libtool need to add -ldl (on most *nix
hosts) to provide dlopen for libbfd.
config/
* plugins.m4 (AC_PLUGINS): If plugins are enabled, add -ldl to
LIBS via AC_SEARCH_LIBS.
gdb/
* acinclude.m4 (GDB_AC_CHECK_BFD): Don't add -ldl.
* config.in: Regenerate.
sim/ppc/
* configure.ac: Invoke AC_PLUGINS.
* config.in: Regenerate.
and regen lots of configure files.
It is rare for people to want to modify the cmd arg. In general, they
really shouldn't be, but a few still do. For those who misbehave, dupe
the string locally so they can bang on it.
sim/rx/gdb-if.c had a function named `rx_signal_to_host'. This
function mapped signal numbers used by the BSP to host signal
numbers which, at one time a while back, were used by GDB
as target signal numbers. This change updates the signal
numbers returned to be those names prefixed with "GDB_SIGNAL_"
as defined in include/gdb/signals.h.
It also changes the name of the function somewhat to better
match what the function currently does. I noticed that this
function is not static - and there's no reason for it not
to be - so I made it static too.
* gdb-if.c (rx_signal_to_host): Rename to
`rx_signal_to_gdb_signal'. Make static. Update all callers
to use new name. Use signal names from include/gdb/signals.h.
I noticed the sim code is using an old implementation of the maintainer logic.
I cut it over to the new macro (like gdb has been doing). In practice, it
makes no difference currently as nothing in the sim tree uses it, but I have a
follow up commit for the Blackfin tree that needs it.
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.
Before POSIX standardized strsignal(), old systems would hide the
prototype unless the normal extension defines were enabled. So use
the AC_USE_SYSTEM_EXTENSIONS helper for that.
Then make sure we include string.h ourselves in nrun.c rather than
relying on implicit includes via other sim headers.
