Move the --sim-enable-assert option up to the common dir so we only
test & export it once across all ports.
|
|
Move the various platform tests up a level to avoid duplication
across the ports. When building multiple versions, this speeds
things up a bit.
For now we move the obvious stuff up a level, but we don't turn
own the config.h entirely just yet -- we still have some tests
related to libraries that need consideration.
|
|
Now that all ports have migrated to the new framework, drop support
for the old sim_state_base layout.
|
|
|
|
The defs.h header will take care of including the various config.h
headers. For now, it's just config.h, but we'll add more when we
integrate gnulib in.
This header should be used instead of config.h, and should be the
first include in every .c file. We won't rely on the old behavior
where we expected files to include the port's sim-main.h which then
includes the common sim-basics.h which then includes config.h. We
have a ton of code that includes things before sim-main.h, and it
sometimes needs to be that way. Creating a dedicated header avoids
the ordering mess and implicit inclusion that shows up otherwise.

This was enabled by default for all targets, but a few ports still
include an explicit call. Clean that up, and update the docs.
|
|
This is needed when building for a target whose ar & ranlib are
incompatible with the current build system. For example, building
for Windows on a Linux system.
Then manually import the automake rule for libigen.a, but tweak the
tool variables to use the FOR_BUILD variants.
|
|
While libiberty provides a definition for this for systems that lack
the function (e.g. Windows), it doesn't provide a prototype. So add
our own local copy in the one file that uses the func.
|
|
Check for __SIZEOF_INT128__ before trying to use the builtin type.
This fixes building on some 32-bit systems like x86.
|
|
The common sim-basics.h defines min/max already, so use them.
|
|
Force this on for all ports. We have a few common models that can
be used, so make them generally available. If the port doesn't use
any hardware (the default), then behavior is unchanged.

This updates the sim so that it unconditionally uses sys/time.h. This
is in agreement with existing code, and a recent change to BFD.
I also think that sys/times.h is never needed by the sim, so this
patch removes the check and the one spot that was conditionally
including it.

GDB has required GNU make for quite some time, and this patch applies
this approach to the sim as well. Requiring GNU make means that
automatic dependency tracking can be simple and reliable, and it also
makes other refactorings simpler.

My scripts weren't updated to use new -I../m4 as the first arg.
|
|
When building with clang, we get:
error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option]
This is because clang only warns by default when encountering an unknown
warning option, and the probe for supported warning flags is done
without -Werror. All flags are therefore accepted by configure, but
then it breaks when actually compiling a source file with -Werror.
This is equivalent to this commit in gdb:
3e019bdc20eb81b91ab5bc774386201b874c0bac
gdb: Use -Werror when checking for (un)supported warning flags
We then see some other compilation errors when building with clang and
-Werror, they can be dealt with later.

This avoids duplicate tests for functions between common m4, arches,
and any other sources that would trigger func tests.
Also manually delete known duplicate function tests between the m4,
bfin, and v850 ports.
|
|
Every arch handles this the same way, so move it to the common code.
This will also make unifying the sim_cpu structure easier.
|
|
The toplevel, common, and igen dirs all have their own code for
setting up toolchain settings. Unify all of that in a new macro.
|
|
All the scripts were using this implicitly already, so there's no real
change for them, but we want to call it explicitly as the CPP tool is
used to generate nltvals.def.
|
|
This file is quite large and is getting unmanageable. Split it apart
to follow aclocal best practices by putting one-macro-per-file. There
shouldn't be any real functional changes here as can be seen in the
configure script regens.
|
|
Rather than hand maintain m4 includes in various autotool files,
use AC_CONFIG_MACRO_DIRS to declare the relevant search paths.
This simplifies the code, makes it more robust, and cleans out
unused logic from configure.
|
|
These settings might have made sense in darker compiler times, but I
think they're largely obsolete now. Looking through the values that
get used in HDEFINES, it's quite limited, and configure itself should
handle them. If we still need something, we can leverage standard
autoconf macros instead, after we get a clear user report.
TDEFINES was never set anywhere and was always empty, so prune that.
|
|
Now the simulator can be loaded via gdb using "target sim".
|
|
This is a hand-written implementation that should have fairly complete
coverage for the base integer instruction set ("i"), and for the atomic
("a") and integer multiplication+division ("m") extensions. It also
covers 32-bit & 64-bit targets.
The unittest coverage is a bit weak atm, but should get better.
