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 was last used 15 years ago, so clearly not important enough to
keep around. Punt it.
|
|
We don't need a variable to add a dependency to the "all" target, and
having one doesn't really add value. Switch to the target directly for
the few ports that actually use this.
|
|
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.
|
|
One fewer file to worry about & manage.

This is needed to move to automake & its dejagnu-provided logic,
and eventually by the unified sim logic. The $arch is used only
to figure out which `run` program to use when running tests, and
as we move to a single top-level build, we can delete this and
use sim/run directly.
|
|
Current toolchains warn about unused result from fread, so mitigate
the edge case if fread returns short data. It's not great, but it
gets things building again.
|
|
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.
|
|
This was missed when we deleted the common/configure build logic.

The rx simulator now has no build warnings. Delete the call to
SIM_AC_OPTION_WARNINGS in configure.ac, the default yes will be
provided by SIM_AC_OUTPUT.

* configure: Regenerate.

Pointer arithmetic on void * pointers results in a GCC warning. Avoid
the warning by casting the pointer to its actual type earlier in the

In load.c there's some GCC warnings about undefined
functions (bfd_get_elf_phdr_upper_bound and bfd_get_elf_phdrs). To
get the declarations of these functions include 'elf-bfd.h'. This
headers also pulls in other elf related headers, like 'elf/internal.h'
and 'elf/common.h', so these no longer need to be explicitly included
from load.c.
In trace.c and include for trace.h is missing, again this results in
GCC warnings for missing function declarations.
sim/rx/ChangeLog:
* load.c: Replace 'elf/internal.h' and 'elf/common.h' includes
with 'elf-bfd.h' include.
* trace.c: Add 'trace.h' include.

For sim code variables still need to be declared at the start of the

While experimenting with switching on warnings for the rx simulator I
discovered this bug. In sim_do_command we get passed a 'const char *'
argument. We create a copy of this string to work with locally, but
then while processing this we accidentally switch back to reference
the original string.
sim/rx/ChangeLog:
* gdb-if.c (sim_do_command): Work with a copy of the command.
|
|
The rx simulator doesn't define sim_memory_map and so fails to link
with GDB. Define it now to return NULL, this can be extended later to
return an actual memory map if anyone wants this functionality.
sim/rx/ChangeLog:
* gdb-if.c (sim_memory_map): New function.
|
|
These ports don't use the common sim core, so they weren't providing
a sim_memory_map for gdb, so they failed to link with the new memory
map logic added for the sim. Add stubs to fix.
|
|
Few arches implement STATE_WATCHPOINTS()->pc while all of them implement
sim_pc_get. Lets switch the sim-watch core for monitoring pc events to
the sim_pc_get API so this module works for all ports, and then we can
delete this old back channel of snooping in the port's cpu state -- the
code needs the pointer to the pc storage so that it can read out bytes
and compare them to the watchrange.
This also fixes the logic on multi-cpu sims by removing the limitation
of only being able to watch CPU0's state.

This dir doesn't use anything from libiberty, so drop the linkage.
|
|
The AC_CONFIG_HEADER macro is long deprecated, so switch to the
newer form. This also gets rid of the position limitation, and
drops support for an argument to SIM_AC_COMMON which we haven't
used anywhere.
|
|
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.
|
|
GCC warns that we pass a non-string literal as the format string,
so add an explicit "%s" to make it happy.
|
|
The extract function takes the argbuf, not the scache.
|
|
We renamed these years ago, but it looks like the cgen core missed the
TRACE_EXTRACT function, so these new ports still used the incompatible
common name. Fix those ports to use the right func.

This port only had one minor warning left in it, so fix it and then
enable -Werror behavior by deleting the macro call. We'll use the
common default now (which is -Werror).

My recent rewrite of the nltvals generator fixed a bug where SYS_times
was not being exported for v850. But that in turn uncovered this bug
where the SYS_times codepath had a compile error.

This tool is only run by developers and not in a release build,
so rewrite it in Python to make it more maintainable.

GCC complains %llu is wrong for signed64, so switch to PRIi64.
|
|
These are only used in this file and lack prototypes, so gcc
complains about it. Add static everywhere to clean that up.

GCC complains that we past non-string literals to a printf style func,
so put a %s in here to keep it quiet.

These files use abort() & strtod(), so include stdlib.h for them.

Existing ports already have sizeof_pc set to the same size as sim_cia,
so simply make that part of the core code. We already assume this in
places by way of sim_pc_{get,set}, and this is how it's documented in
the sim-base.h API.
There is code to allow sims to pick different register word sizes from
address sizes, but most ports use the defaults for both (32-bits), and
the few that support multiple register sizes never change the address
size (so address defaults to register). I can't think of any machine
where the register hardware size would be larger than the address word
size either. We have ABIs that behave that way (e.g. x32), but the
hardware is still equivalent register sized.
|
|
When the target's PC is 64-bits, this shift expands into a range of
8 * 8 - 1 which doesn't work with 32-bit constants. Force it to be
a 64-bit value all the time and let the compiler truncate it.
|
|
This port doesn't build if these hardware modules are omitted, and
there's no reason we need to make it conditional at build time, so
always enable it. The hardware devices only get turned on if the
user requests it at runtime via hardware settings.
|
|
This avoids fixed sized buffers on the stack.
|
|
This was largely already done, but I think people didn't quite notice.

This wasn't supposed to be in here when it was first merged as we
had specifically disabled it for all the tests (and ADI has papers
in place w/the FSF). Clean up this one.
