c1230d1bab [src/erc32] Use ncurses instead of termcap on Cygwin too
This removes a Cygwin-specific libtermcap hack that was dependent on
the presence of one of the multiple alternative libraries.  The one it
was hard-coded to pick isn't included with Cygwin anymore.

According to Corinna, libtermcap was removed from Cygwin a long time
ago, and libncurses is used in Cygwin for a long time too.

The fix is to make Cygwin use the same autoconf code to figure out the
correct lib as any other target.

sim/erc32/Changelog:
2018-10-30  Joel Sherrill <joel@rtems.org>

	* configure.ac: Remove the Cygwin-specific libtermcap.a hack
	and use the standard logic to determine which library to use.
	* configure: Regenerate.

ce39bd3890 sim: move many common settings from CPPFLAGS to config.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.

e19418e02e sim: drop unused SIM_AC_OPTION_PACKAGES
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.

16f7876d71 sim: allow the environment configure option everywhere
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.

35656e9521 sim: allow the assert configure option everywhere
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.

99d8e87993 sim: drop targ-vals.def->nltvals.def indirection
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.

This way we get standard behavior across all ports too.

0dc73ef7c3 sim: drop --enable-sim-{regparm,stdcall} options
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.

22be3fbeac sim: drop --enable-sim-cflags option
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.

936df7568a sim: drop common/cconfig.h in favor of a single config.h
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.

9bbf6f91c6 sim: punt x86-specific bswap logic
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.

0cb8d8513c sim: drop host endian configure option
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.

1ac72f0659 sim: convert to bfd_endian
Rather than re-invent endian defines, as well as maintain our own list
of OS & arch-specific includes, punt all that logic in favor of the bfd
ones already set up and maintained elsewhere.  We already rely on the
bfd library, so leveraging the endian aspect should be fine.

1b393626ce sim: punt WITH_DEVICES & tconfig.h support
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.

Change data ordering in emulated memory from target order (big endian)
to host order. Improves performance and simplifies most memory

endian hosts (intel). Also removed support for little-endian binaries.

ae7d0cac8c sim: rename tconfig.in to tconfig.h
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.

465fb143c8 sim: make nrun the default run program
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.
