Mike Frysinger 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.

Mike Frysinger 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.
2016-01-10 17:54:04 -05:00
Mike Frysinger 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.
2016-01-10 17:03:36 -05:00
Mike Frysinger 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.
2016-01-10 16:13:13 -05:00
Mike Frysinger 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.
2016-01-10 04:01:16 -05:00
Mike Frysinger 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.

Mike Frysinger 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.
2016-01-10 03:15:01 -05:00
Mike Frysinger 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.
2016-01-10 02:54:59 -05:00
Mike Frysinger 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.

Mike Frysinger 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.

Mike Frysinger 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.
2016-01-04 05:04:30 -05:00
Mike Frysinger 77cf2ef5dc sim: parse_args: display getopt error ourselves
Fix a long standing todo where we let getopt write directly to stderr
when an invalid option is passed.  Use the sim io funcs instead as they
go through the filtered callbacks that gdb wants.
2016-01-03 22:07:39 -05:00
Mike Frysinger 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.
2016-01-03 00:52:51 -05:00
Mike Frysinger 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.

Mike Frysinger 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.
2015-12-27 00:54:41 -05:00
Mike Frysinger 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.

Mike Frysinger 9db2b71908 sim: cris: move option install to sim_open
We've moved custom option install for other targets to sim_open, so update
cris too.  It's the last one using MODULE_LIST, so we can drop that from
the common code too.
2015-12-24 20:34:07 -05:00
Mike Frysinger 797eee4264 sim: sim-stop/sim-reason/sim-reg: move to common obj list
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.
2015-11-16 00:41:59 -05:00
Mike Frysinger 9db36cf86d sim: cr16: drop global callback state
Now that we have access to the sim state in all the right places,
use existing sim helpers in place of cr16_callback directly.
2015-11-15 21:49:41 -05:00
Mike Frysinger 0ef7f98177 sim: cr16: convert to common sim engine logic
Now that we have access to the sim state everywhere, we can convert to
the common engine logic for overall processing.  This frees us up from
tracking exception state ourselves.
2015-11-15 21:48:58 -05:00
Mike Frysinger 761e171ad8 sim: cr16: convert to common sim memory modules
The cr16 port has a lot of translation/offset logic baked into it, but
it all looks like copy & paste from the d10v port rather than something
the cr16 port wants.
2015-11-15 21:48:06 -05:00
Mike Frysinger 267b3b8e06 sim: cr16: push down sd/cpu vars
By itself, this commit doesn't really change anything.  It lays the
groundwork for using the cpu state in follow up commits, both for
engine state and for cpu state.  Splitting things up this way so it
is easier to see how things have changed.
2015-11-15 21:46:13 -05:00
Mike Frysinger 137fbfd281 sim: cr16: delete unused memory helpers
These aren't used anywhere and are just leftover from the d10v port.
Delete them so follow up commits are easier to follow.
2015-11-15 21:35:31 -05:00
Mike Frysinger c2270cd8a6 sim: cr16: switch to common sim-reg
This is mostly to get us off the weird cr16 specific memory functions,
but it's also a good clean up to move to the common core.
2015-11-15 21:23:09 -05:00
Mike Frysinger 7ea08e8cb7 sim: cr16/d10v: drop redundant call to sim_create_inferior
With the conversion to the nrun frontend, this call should no longer be
necessary.  It also actively crashes when trying to use the sd state.
2015-11-15 20:47:31 -05:00
Mike Frysinger 6e4f085c7f sim: sim-close: unify sim_close logic
Other than the nice advantage of all sims having to declare one fewer
common function, this also fixes leakage in pretty much every sim.
Many were not freeing any resources, and a few were inconsistent as
to the ones they did.  Now we have a single module that takes care of
all the logic for us.

Most of the non-cgen based ones could be deleted outright.  The cgen
ones required adding a callback to the arch-specific cleanup func.
The few that still have close callbacks are to manage their internal
state.

We do not convert erc32, m32c, ppc, rl78, or rx as they do not use
the common sim core.

Mike Frysinger 6637a4265e sim: cr16/d10v: localize translation funcs
These functions are only used in the interp module, so there's no point
in exporting them and declaring them in the external sim interface.

Mike Frysinger a348708291 sim: drop -DTRACE from configure
No code uses this anymore and the symbol conflicts with the new TRACE
helper.  Punt it from configure.

Mike Frysinger 20bca71d82 sim: unify SIM_CPU definition
Since every target typedefs this the same way, move it to the common code.

We have to leave Blackfin behind here for now because of inter-dependencies
on types and headers: sim-base.h includes sim-model.h which needs types in
machs.h which needs types in bfim-sim.h which needs SIM_CPU.
2015-04-18 04:31:36 -04:00
Mike Frysinger 7e83aa92f2 sim: unify sim_cia definition
Almost every target defines sim_cia the same way -- either using the
address_word type directly, or a type of equivalent size.  The only
odd one out is sh64 (who has 32bit address_word and 64bit cia), and
even that case doesn't seem to make sense.  We'll put off clean up
though of sh64 and at least set up a sensible default for everyone.
2015-04-18 04:14:38 -04:00
Mike Frysinger 034685f9ce sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET}
The CIA_{GET,SET} macros serve the same function as CPU_PC_{GET,SET}
except the latter adds a layer of indirection via the sim state.  This
lets models set up different functions at runtime and doesn't reach so
directly into the arch-specific cpu state.

It also doesn't make sense to have two sets of macros that do exactly
the same thing, so lets standardize on the one that gets us more.

Mike Frysinger 27b97b40bc sim: arm/cr16/d10v/h8300/microblaze/sh: fill out sim-cpu pc fetch/store helpers
This makes the common sim-cpu logic work.
2015-04-17 02:22:16 -04:00
Mike Frysinger 78e9aa70fe sim: unify sim-cpu usage
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.

Mike Frysinger 122bbfb52a sim: move sim-engine.o/sim-hrw.o to the common list
This makes these two objects available to all sims by default.

Mike Frysinger 0fe84f3fbe sim: run: punt!
Now that all targets have been converted to nrun, we can finally punt
this old inconsistent interface.

A few stray references to the old run were sprinkled about; clean them
up in the process.

We leave behind the run(1) man page mostly so that we get it updated for
the new nrun interface.

Mike Frysinger b38f7f340b sim: cr16/d10v: restore generated headers dep
While cleaning up stale make rules, one too many were deleted.  The

2015-03-31 01:59:44 -04:00
Mike Frysinger 247ac9ee6e sim: cr16: convert to nrun
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.

Mike Frysinger 4b0cc5edf4 sim: cr16: delete NEED_UI_LOOP_HOOK handling
This hook is used only when linked into gdb, and cr16 doesn't have a gdb

Mike Frysinger 1e504675bd sim: cr16: delete dead code

Mike Frysinger ca968da465 sim: cr16: use common configure options
In preparation for converting to nrun, call the common functions that
are needed.  This doesn't produce any new warnings, and the generated
code should be the same.
2015-03-29 22:42:33 -04:00
Mike Frysinger 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.
2015-03-16 01:23:52 -04:00
Mike Frysinger 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.

Mike Frysinger 5cddc23a3a sim: drop duplicate header checks
The SIM_AC_COMMON macro already checks for a bunch of headers, so specific
