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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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 82d442c6c6 sim: avr: move global state to sim/cpu state
We don't want global variables in the sim as all state should be in the
sim state or in the cpu state.  This pushes down all that logic for avr.

Mike Frysinger 807eaf04cb sim: avr: switch to common sim-reg
This is not entirely useful as avr doesn't (yet) store its register

arch ports.

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 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.

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 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 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 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.

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.
