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.

347fe5bb86 sim: allow the inline configure option everywhere
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.

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.

2e3d4f4d5d sim: sim_{create_inferior,open,parse_args}: constify argv/env slightly
2016-01-03  Mike Frysinger  <vapier@gentoo.org>

	* sim-options.c (sim_parse_args): Mark argv array const.
	* sim-options.h (sim_parse_args): Likewise.

The output should largely be the same.

bc273e1751 sim: unify min/max macros
Import defines from gdb/defs.h to the sim core so we can delete the
various copies that already exist.

ac8eefeb24 sim: aarch64: drop syscall.h include to fix build
The simulator is including syscall.h which is not standard and apparently
not required (builds correctly without it on my machine).

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.

5d01527536 sim: aarch64/msp430: fix disassembler usage
The disasm framework reserves the private_data field for the disassemblers
themselves, not for people who use the disassembler.  Instead, there is an
application_data field for callers such as the sim.  Switch to it to avoid
random corruption/crashes when the disassemblers use private_data.

5e744ef887 sim: unify sim-hload
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.

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.

0e9672991e sim: standardize sim_create_inferior handling of argv a bit more
For targets that process argv in sim_create_inferior, improve the code:
- provide more details in the comment
- make the check for when to re-init more robust
- clean out legacy sim_copy_argv code

This will be cleaned up more in the future when we have a common inferior
creation function, but at least help new ports get it right until then.
