Delete redundant decls when the existing scope has the same var and
type available for use.
|
|
Seems like these cases were meant to fallthru.
|
|
All funcs already call other funcs that don't return. The mips port is
the only exception because its generic exception handler can return in
the case of normal exceptions. So while the exceptions its signal handler
triggers doesn't return, we can't express that conditional logic. So add
some useless abort calls to make the compiler happy.

According to we have changed all E_MIPS_* to EF_MIPS_* in binutils
and glibc, we also need to change it here to keep same style.
We can refer to this commit record:

Clean up includes a bit by making ports include bfd/ headers
explicitly. This matches other projects, and makes it more clear
where these headers are coming from.
|
|
All the runtimes were only initializing a single CPU. When SMP is
enabled, things quickly crash as none of the other CPU structs are
setup. Change the default from 0 to the compile time value.

The latter type matches the address size configured for this sim.
Also take the opportunity to simplify printf logic by leveraging
PRI* macros.

When reading/writing arbitrary data to the system's memory, the unsigned
char pointer type doesn't make that much sense. Switch it to void so we
align a bit with standard C library read/write functions, and to avoid
having to sprinkle casts everywhere.

These functions only read from memory, so mark the pointer as const.

PTR will soon disappear from ansidecl.h. Remove uses in sim. Where
a PTR cast is used in assignment or function args to a void* I've
simply removed the unnecessary (in C) cast rather than replacing with
(void *).

Move off the sim-specific unsignedXX types and to the standard uintXX_t
types that C11 provides.
|
|
This doesn't fix all the problems, but grabs a bunch of the more
obvious ones.
|
|
Some C libraries export _P symbols in their headers (like older
newlib and its ctype.h), so use P_ instead to avoid conflicts.
|
|
We use the program argv to both find the program to run (argv[0]) and
to hold the arguments to the program. Most of the time this is fine,
but if we want to let programs specify argv[0] independently (which is
possible in standard *NIX programs), this double duty doesn't work.
So let's split the path to the program to run out into a separate
field by itself. This simplifies the various sim_open funcs too.
By itself, this code is more of a logical cleanup than something that
is super useful. But it will open up customization of argv[0] in a
follow up commit. Split the changes to make it easier to review.
|
|
The sim-basics.h is too big and includes too many things. This leads
to some arch's sim-main.h having circular loop issues with defs, and
makes it hard to separate out common objects from arch-specific defs.
By splitting up sim-basics.h and killing off sim-main.h, it'll make
it easier to separate out the two.
|
|
This helps catch format errors in code, although they're all clean
at this point already.
|
|
The compiler doesn't like passing non-constant strings to printf
functions, so tweak the code to always pass one in. This code is
a little more verbose, but it's probably the same performance.
The macro usage is a bit ugly, but maybe less than copying &
pasting the extended conditional format logic.
|
|
The majority of these inputs are not long's, so don't use %lx.
This fixes compiler warnings about type mismatches.
|
|
Make sure we don't fail to build when dv-socker is unavailable.

32-bit MIPS programs run on the 64-bit simulator model in 64-bit
sign-extended space. The mapping from 64-bit sign-extended addresses to
32-bit addresses was removed by commit
26f8bf63bf36f9062a5cc1afacf71462a4abe0c8, breaking the 64-bit simulator
model. Add shadow mappings from 64-bit sign extended address space to
32-bit address spaces, in lieu of the AddressTranslation function.

64-bit BFD for MIPS applies a standard sign extension on all addresses
assuming 64-bit target. These bits are required for 64-bit and can only
be safely truncated for 32-bit target models. This partially reverts commit
b36d953bced0a4fecdde1823abac70ed7038ee95
The sign-extension logic modeled by BFD is an integral part of the
MIPS64 architecture spec. It appears in the virtual address map, where
sign extension allows for 32-bit compatibility segments [1] with 64-bit
addressing. Truncating these addresses prematurely (commit
models (-DWITH_TARGET_WORD_BITSIZE=64).
In the ISA itself, direct addressing (Load-Upper-Immediate) and indirect
addressing (Load-Word) both automatically sign-extend their results. These
instructions regenerate the sign-extended addresses even if we don't start
with one (see pr gdb/19447).
Moreover, some instructions like ADD*/SUB* have unpredictable behaviour when
an operand is not correctly sign extended [3]. This affects PC-relative
addressing in particular, so arithmetic on the link-address generated in the
return address register by a jump-and-link is no longer possible, neither is
the use of the PC-relative addressing instructions provided by MIPSR6.

* interp.c (sim_create_inferior): Only truncate sign extension
bits for 32-bit target models
.

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.
|
|
The gdb/callback.h & gdb/remote-sim.h headers have nothing to do with
gdb and are really definitions for the libsim API under the sim/ tree.
While gdb uses those headers as a client, it's not specific to it. So
create a new sim/ namespace and move the headers there.
|
|
Every arch handles this the same way, so move it to the common code.
This will also make unifying the sim_cpu structure easier.
|
|
sim/mips/ChangeLog
* interp.c (sim_monitor): Add switch entries for unlink (13),
lseek (14), and stat (15).
Derived from patch authored by Steve Ellcey <sellcey@mips.com>
|
|
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.
|
|
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.
|
|
Since we require C11 now, we can assume many headers exist, and
clean up all of the conditional includes. It's not like any of
this code actually accounted for the headers not existing, just
whether we could include them.
The strings.h cleanup is a little nuanced: it isn't in C11, but
every use of it in the codebase will include strings.h only if
string.h doesn't exist. Since we now assume the C11 string.h
exists, we'll never include strings.h, so we can delete it.
|
|
The mips bfd will sign extend 32-bit addresses into 64-bit values,
so if the entry happens to be 0x80000000 or higher, it is turned to
0xffffffff80000000 which points to memory that doesn't exist.
This wasn't an issue until commit 26f8bf63bf36f9062a5cc1afacf71462a
as all addresses were automatically truncated there in the translate
function to 32-bits. When we cleaned up that code, the full 64-bits
were checked leading to many test failures for mips-sde-elf targets
and such.

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

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.
|
|
to common sim_{fetch,store}_register
|
|
The only unique thing about mip's sim_{read,write} helpers is the call to
address_translation on the incoming address. When we look closer at that
function though, we see it's just a stub that maps physical to virtual,
and the cache/return values are hardcoded. If we delete this function,
we can then collapse all the callers and drop the custom sim_{read,write}
logic entirely.
Some day we might want to add MMU support, but when we do, we'll want to
have the common layers handle things so all targets benefit.
|
|
No target has used this, and it's a cheap hack in place in using the
common memory module. We want everyone using that though, so drop
support for flatmem entirely.
|
|
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.

We want to add new common trace helpers including "TRACE", so change the
mips one to the new WITH_TRACE_ANY_P macro since they do the same thing.
|
|
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.
|
|
Make cpu allocation fully dynamic so we can leverage the common
sim-cpu and its APIs.
|
|
Convert a bunch of old style prototypes and tweak various casts
to match the function signatures.
|
|
The previous profile change broke these sims that use sim-profile but
not sim-cpu (due to missing model support). Add simple funcs until we
can convert these over properly.
