Fix some of the sim_fpu calls to use the right types. While I'm
not familiar with the MIPS ISA in these cases, these look like
simple oversights due to the name/type mismatches. This at least
fixes compiling with -Wenum-conversion.
No functional change here, but makes it a little easier to read the
generated code when editors aren't highlighting all the spurious
trailing whitespace on lines.
The sim_stop argument is an enum and should only be one of those
values, not a signal constant. Fix the logic to pass the right
sim_xxx & SIM_xxx values in the right arguments.
We only support UTF-8 nowadays, so stop using ISO-8859-1.
Maybe we should delete this logic entirely, but for now,
do the bare min conversion to keep it compiling.
Reuse the bfd/development.sh script like most other project to
determine whether the current source tree is a dev build (e.g.
git) or a release build, and disable the warnings for releases.
This code tries to use attach_type enums as hw_phb_decode, and while
they're setup to have compatible values, the compiler doesn't like it
when the cast is missing. So cast it explicitly and then use that.
sim/ppc/hw_phb.c:322:28: error:
implicit conversion from enumeration type 'attach_type'
(aka 'enum _attach_type') to different enumeration type
'hw_phb_decode' [-Werror,-Wenum-conversion]
Don't conflate HAVE_GETRUSAGE & HAVE_SYS_RESOURCE_H. Use the latter
to include the header and nothing else. Use the former to determine
whether to use the function and nothing else. If we find a system
that doesn't follow POSIX and provides only one of these, we can
figure out how to support it then. The manual local definition is
clashing with the system ones and leading to build failures with
newer C standards.
sim/ppc/emul_netbsd.c:51:5: error: a function declaration without a
prototype is deprecated in all versions of C and is treated as a

If the value to be shifted has the sign bit set, the sign
bit would get copied into bits 32..63 of the temporary. Those
would then be right shifted into the final value giving an
incorrect final result.
This was observed with upcoming GCC improvements which eliminate
unnecessary extensions.
The BPF assembler has been updated to follow the clang convention in
the interpretation of semicolons: they separate statements and
directives, and do not start line comments.
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.

Fix 32bit 'jalr rd,ra,imm' integer instruction, where RD was written
before using it to calculate destination address.
This commit also improves testutils.inc for riscv; make use of
pushsection and popsection when adding things to .data, and setup the
%gp global pointer register within the 'start' macro.

I was looking for cases where a GCC patch under evaluation would cause test
results to change. Quite surprisingly the mcore-elf port showed test
differences. After a fair amount of digging my conclusion was the sequences
before/after the patch should have been semantically the same.
Of course if the code is supposed to behave the same, then that points to
problems elsewhere (assembler, linker, simulator). Sure enough the mcore
simulator was mis-handling the sign extension instructions. The simulator
implementation of sextb is via paired shift-by-24 operations. Similarly the
simulator implements sexth via paired shift-by-16 operations.
The temporary holding the value was declared as a "long" thus this approach
worked fine for hosts with a 32 bit wide long and failed miserably for hosts
with a 64 bit wide long.
This patch makes the shift count automatically adjust based on the size of the
temporary. It includes a simple test for sextb and sexth. I have _not_ done a
full audit of the mcore simulator for more 32->64 bit issues.
This also fixes 443 execution tests in the GCC testsuite
This patch sets GUILE to just plain 'guile'.
In the distant ("devo") past, the top-level build did support building
Guile in-tree. However, I don't think this really works any more.
For one thing, there are no build dependencies on it, so there's no
guarantee it would actually be built before the uses.
This patch also removes the use of "-s" as an option to cgen scheme
scripts. With my latest patch upstream, this is no longer needed.
After the upstream changes, either Guile 2 or Guile 3 will work, with
or without the compiler enabled.

This fixes test failures caused by the new linker warning which report:
./ld/ld-new: warning: load.S.x has a LOAD segment with RWX permissions
Fix this by splitting the linker MEMORY into ram and rom to avoid
generating RWX sections. This required tests to be adjusted to fix
issues with the move. Namely:
- fpu tests: were incorrectly using l.ori with ha(anchor) which now
that we pushed the anchor up in memory it exposes the bug. Update
to used the correct l.movhi instruction instead.
- adrp test: the test reports ram offset addresses, now that we have
moved memory layout around a bit I adjusted the test output. Some
padding is added before pi to show that the actual address of pi and
the adrp page offset are not the same.
Bug: https://sourceware.org/PR29957
The BPF virtual machine does not support neg instructions operating on
immediates, and these erroneous instructions were recently removed from
gas. Remove them from the simulator as well.
I get a couple of -Wmissing-declarations errors when building the sim.
This happens because an earlier patch added the declarations to a
cgen-generated header, but the recent re-generation then removed them.
This patch fixes the build by adding declarations just before the
definition. This is normally not best practice, but in this
particular situation it at leat un-breaks the build.
I saw this warning from make:
Makefile:5043: *** mixed implicit and normal rules: deprecated syntax
I believe this snuck in by error with the recent cgen-related changes.
This patch removes the stray '%' and rebuilds the Makefile.in. I'm
checking this in.
This regenerates sim files.
Tested with the following tools from a recent binutils build in
sim-site-config.exp, plus a few cross compilers.

I had reason yesterday to want to regenerate configury files which I
do with --enable-maintainer-mode, and added --enable-cgen-maint
accidentally. The first problem I hit is that sim looks for cgen in a
different directory by default than opcodes, and I had my source
layout set up for opcodes rather than sim. Fix that by making both
use ../cgen first, then ../../cgen relative to sim/ and opcodes/. The
next problem was that various sim local.mk files expected generated
sources in the build dir rather than the source dir. Fix that by
adding $(srcdir) to paths. Finally, the generated iq2000 files had a
compile error, fixed by the cpu/iq2000.cpu patch.
cpu/
* iq2000.cpu (syscall): Add pc arg.
opcodes/
* configure.ac (cgendir): Default to ../../cgen, but use ../cgen
if found there.
* configure: Regenerate.
sim/m4/
* sim_ac_option_cgen_maint.m4 (cgendir): Look in ../cgen too.
sim/
* cris/local.mk: Add $(srcdir) to paths for regenerated source.
* frv/local.mk: Likewise.
* iq2000/local.mk: Likewise.
* lm32/local.mk: Likewise.
* m32r/local.mk: Likewise.
* or1k/local.mk: Likewise.
* Makefile.in: Regenerate.
* configure: Regenerate.
Remove some of the warnings generated by newer versions of ld.
* testsuite/lib/sim-defs.exp (prune_warnings_extra): New.
Arrange to run it from prune_warnings.
Commit f00b50d057 went the wrong way. As the comment says this
function is only applicable to fr550. If not fr550 return 1,
meaning we don't have acc restrictions.
This regenerates config files changed by the previous 44 commits.
Note that subject lines in these commits mostly match the gcc git
originating commit.
These were renamed from bfd_read and bfd_write back in 2001 when they
lost an unnecessary parameter. Rename them back, and get rid of a few
casts that are only needed without prototyped functions (K&R C).
This patch fixes some instructions in the BPF tests that overflow the
signed immediates. Note that this happened to work before by chance,
as GAS would silently truncate.
Tested in bpf-unknown-none.

This patch fixes the semantics of the neg and neg32 BPF instructions
in the simulator, and also updates the corresponding tests
accordingly.
Tested in target bpf-unknown-none.
The BPF port in binutils has been rewritten (commit
d218e7fedc) in order to not be longer
based on CGEN. Please see that commit log for more information.
This patch updates the BPF simulator accordingly. The new
implementation is much simpler and it is based on the new BPF opcodes.
Tested with target bpf-unknown-none with both 64-bit little-endian
host and 32-bit little-endian host.
Note that I have not tested in a big-endian host yet. I will do so
once this lands upstream so I can use the GCC compiler farm.
The verbose argument has always been an int treated as a bool, so
convert it to an explicit bool. Further, update the API docs to
match the reality that the verbose value is actually used by some
of the internal modules.
Now that sim-main.h has been reduced significantly, we can remove it
from sim-signal.c and unify it across all boards since it compiles to
the same code.
sim-main.h is special since it is one of the files automatically
included in igen generated files. But this means anything including
sim-main.h might get everything included just for the igen files.
To prevent clashing symbols/defines only include sim-fpu.h,
sim-signal.h, mn10300-sim.h from sim-main.h if it is included
from one of the generated igen C files. Add explicit includes
of mn10300-sim.h, sim-fpu.h and/or sim-signal.h to dv-mn103cpu.c,
interp.c and op_utils.c.
This has never been installed, and it's not clear anyone cares about
it in the local build dir (when the main program is sim/ppc/run), so
drop all the logic to simplify.
We have many uses of sys/stat.h that are unprotected by HAVE_SYS_STAT_H,
so this is more formalizing the reality that we require this header.
Since we switched to gnulib, it guarantees that a sys/stat.h exists
for us to include, so we're doubly OK.
We have many uses of unistd.h that are unprotected by HAVE_UNISTD_H,
so this is more formalizing the reality that we require this header.
Since we switched to gnulib, it guarantees that a unistd.h exists
for us to include, so we're doubly OK.
This logic was added in order to expose the strsignal prototype for
nrun.c. Since then, we've migrated to gnulib as our portability layer,
and it takes care of probing system extensions for us, so there's no
need to duplicate the work.
Add explicit arch-specific modules.c rules to keep the build from
generating an incorrect common/modules.c. Otherwise the pattern
rules would cascade such that it'd look for $arch/modules.o which
turned into common/modules.c which triggered the gen rule.
My local testing of this code didn't catch this bug because of how
Automake manages .Po (dependency files) in incremental builds -- it
was adding extra rules that override the pattern rules which caused
the build to generate correct modules.c files. But when building
from a cold cache, the pattern rules would force common/modules.c to
be used leading to crashes at runtime.
Now that all ports (that use igen) build in the top-level and depend
on igen, we can move the conditional logic out of configure. We also
switch from noinst_LIBRARIES to EXTRA_LIBRARIES so that the library
is only built when needed (i.e. the igen tool is used).
Now that all ports (other than ppc) build in the top-level, we don't
need to expand all the modules.c targets as a recursive dep. Each
port depends on their respective file now, and the ppc port doesn't
use it at all.
This makes sure the arch-specific modules.c wildcard is matched and
not the common/%.c so that we compile it correctly. It also makes
sure each subdir has depdir logic enabled.
Now that we build these objects in the top dir & generate modules.c
there, we don't need to generate them all first -- we can let the
normal dependency graph take care of building things in parallel.
