2021-04-22Require GNU makeTom Tromey65-2102/+205
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. sim/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * m4/sim_ac_common.m4 (SIM_AC_COMMON): Don't check for make. sim/aarch64/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/arm/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/avr/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/bfin/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Make-common.in: Require GNU make. sim/cr16/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/cris/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/d10v/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/erc32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/example-synacor/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/frv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/ft32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/h8300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/iq2000/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/lm32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/m32c/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/m32r/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/m68hc11/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/mcore/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/microblaze/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/mips/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/mn10300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/moxie/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/msp430/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/or1k/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/pru/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/riscv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/rl78/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/rx/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/sh/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/v850/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild.
2021-04-22Add stamp files for generated files in sim/ppcTom Tromey2-2/+13
This changes the sim/ppc Makefile to use the stamp file idiom for a couple of generated files, avoiding extra rebuilds. sim/ppc/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Makefile.in (stamp-vals, stamp-map): New targets. (targ-vals.h, targ-map.c): Update. (clean): Remove files.
2021-04-22Introduce stamp file for hw-config.hTom Tromey2-2/+11
This adds a stamp file for hw-config.h, to avoid unnecessary rebuilds. It also arranges to remove hw-config.h in "mostlyclean", because the file is created by "make". sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Make-common.in (stamp-hw): New target. (hw-config.h): Depend on stamp-hw. (mostlyclean): Remove stamp-hw and hw-config.h.
2021-04-22Make mostlyclean an alias for cleanTom Tromey2-2/+7
I found out by accident that "mostlyclean" in a sim subdir removes all the configure artifacts. The usual rule is: * If the maintainer built it, maintainer-clean should remove it; * If configure built it, distclean should remove it; * If make built it, "clean" should remove it; * If there is a handy subset of "clean" that is "easy" to rebuild, "mostlyclean" should remove it; otherwise mostlyclean should be an alias for clean This patch makes mostlyclean an alias for clean. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Make-common.in (mostlyclean): Now an alias for clean, not distclean.
2021-04-22Fix sim build failureTom Tromey2-4/+6
On x86-64 Fedora 32, the sim was failing to build. sim_events_schedule was passing a 'dummy' argument to sim_events_schedule_vtracef, which caused an error because the format parameter was NULL. However, removing this dummy argument caused an error because too few arguments were being passed -- catch 22. This patch fixes the build problem by using sim_events_schedule_tracef instead. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * sim-events.c (sim_events_schedule): Use sim_events_schedule_tracef.
2021-04-22sim: sprinkle some ATTRIBUTE_PRINTFSimon Marchi4-8/+16
Add some ATTRIBUTE_PRINTF attributes to functions that take a format string, to fix a few -Wformat-nonliteral warnings. Use the ATTRIBUTE_PRINTF macro like we use in GDB, instead of spelling out __attribute__((format...)). Use ATTRIBUTE_NULL_PRINTF at one place, because callers expect to be able to pass NULL. sim/common/ChangeLog: * callback.c (os_printf_filtered, os_vprintf_filtered, os_evprintf_filtered, os_error): Use ATTRIBUTE_PRINTF. * sim-engine.h (sim_engine_abort, sim_engine_vabort): Likewise. * sim-events.h (sim_events_schedule_tracef, sim_events_schedule_vtracef): Use ATTRIBUTE_NULL_PRINTF.

2021-04-21sim: regen against sim/m4/Mike Frysinger62-305/+429
My scripts weren't updated to use new -I../m4 as the first arg.
2021-04-21sim: use -Werror when probing for supported warning flagsSimon Marchi64-32/+161
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.
2021-04-20sim: rl78/rx: drop unnecessary getopt.h probingMike Frysinger10-28/+16
Since getopt.h is provided by libiberty, there's no need to probe for a system version of it. Plus we already assume it exists in other parts of the sim.
2021-04-18sim: switch to AC_CHECK_HEADERS_ONCEMike Frysinger51-1698/+1580
This avoids duplicate tests for headers between common m4, arches, and any other sources that would trigger header tests.
2021-04-18sim: msp430: delete unused getopt.h probeMike Frysinger4-18/+5
This port doesn't include it anywhere, so drop the test.
2021-04-18sim: moxie: switch syscalls to common nltvalsMike Frysinger6-5/+52
Rather than hand duplicate the syscall constants, switch to the common nltvals framework. I made sure the constants have the same values before & after too :).
2021-04-18sim: sh: switch syscalls to common nltvalsMike Frysinger7-59/+77
Rather than hand duplicate the syscall table, switch to the common nltvals framework. We have to tweak the constant names, but we get everything else for free. I made sure the constants have the same values before & after too :).
2021-04-18sim: rx: switch syscalls to common nltvalsMike Frysinger7-62/+59
Rather than hand duplicate the syscall table, switch to the common nltvals framework. We have to tweak the constant names, but we get everything else for free. I made sure the constants have the same values before & after too :).
2021-04-18sim: m32c: switch syscalls to common nltvalsMike Frysinger7-60/+56
Rather than hand duplicate the syscall table, switch to the common nltvals framework. We have to tweak the constant names, but we get everything else for free. I made sure the constants have the same values before & after too :).
2021-04-18sim: iq2000: switch syscalls to common nltvalsMike Frysinger6-30/+56

2021-04-18sim: switch to AC_CHECK_FUNCS_ONCE & merge a littleMike Frysinger66-799/+1675
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.
2021-04-18sim: mn10300: delete unused func & header testsMike Frysinger5-52/+6
These appear to have been blindly copied from the v850 port many years ago as the code has never been used. Just delete it all and be done.
2021-04-18sim: syscall: add getpid supportMike Frysinger6-4/+34
Hoist the Blackfin implementation up to the common one.
2021-04-18sim: d10v: fix build warningsMike Frysinger4-5/+17
The printf fix uses our PRIxTA for our sim address type. Then cast away the const (since the underlying code safely treats it as such) even if it's ugly. Finally touch up the argv iterator pointer to match the new func arg. With this tidied up, we can delete the SIM_AC_OPTION_WARNINGS(no) call to get the default common behavior where -Werror is enabled.
2021-04-18sim: cr16: fix build warningsMike Frysinger4-4/+14
The printf fix is obvious enough, but the hash one is a real bug: cr16/interp.c: In function 'sim_open': cr16/interp.c:560:17: error: 'h' may be used uninitialized in this function [-Werror=maybe-uninitialized] 560 | h = h->next; | ~~^~~~~~~~~ It happens to not cause a problem currently because the first entry in the generated table that this loop operates matches a codepath where h is initialized. Then when later entries don't match, the previous value is pointing at the end of a valid hash table already, and the rest of the code does nothing. With this tidied up, we can delete the SIM_AC_OPTION_WARNINGS(no) call to get the default common behavior where -Werror is enabled.
2021-04-15sim erc32: Add include path for readline.John Baldwin4-3/+21
Add a READLINE_CFLAGS variable which adds the include path to the in-tree readline when using the in-tree readline library. sim/erc32/ChangeLog: * Makefile.in (READLINE_SRC, READLINE_CFLAGS): Add. (SIM_EXTRA_CFLAGS): Add READLINE_CFLAGS. * configure: Rebuild. * configure.ac (READLINE_CFLAGS): Add.
2021-04-15sim mn10300: Fix igen generation.John Baldwin3-2/+9
Only pass the top-level instruction decode table (mn10300.igen) to igen via -i. The additional files passed previously caused igen to exit its getopt loop in main and exit silently without generating any output. In addition, when am33-2.igen was added, it was not included from mn10300.igen, so was never used. sim/mn10300/ChangeLog: * Makefile.in: (tmp-igen) Only pass mn10300.igen to igen. * mn10300.igen: Include am33-2.igen.
2021-04-15sim lm32: Use a known-good shell with genmloop.sh.John Baldwin2-1/+5
Explicitly use a known-good shell found by autoconf for executing additional scripts in genmloop.sh rather than the building user's shell. sim/lm32/ChangeLog: * Makefile.in: Pass -shell to genmloop.sh.
2021-04-15sim frv: Add a missing return value for frvbf_check_acc_range.John Baldwin2-1/+5
Claim that the accumulator indices are out of range without raising an exception if the CPU doesn't support media instructions. sim/frv/ChangeLog: * traps.c (frvbf_check_acc_range): Add missing return value.
2021-04-15sim: Add SIM_EXTRA_CFLAGS after CSEARCH.John Baldwin2-4/+9
The bfin sim adds include paths for the SDL libraries. These include paths might include headers for different version of binutils. Move SIM_EXTRA_CFLAGS after CSEARCH to ensure local includes are always preferred to external includes. sim/common/ChangeLog: * Make-common.in (CONFIG_CFLAGS): Remove SIM_EXTRA_CFLAGS. (ALL_CLAGS, COMMON_DEP_CFLAGS): Add SIM_EXTRA_CFLAGS after CSEARCH.
2021-04-12sim: cgen: move cgen_cpu_max_extra_bytes logic into the common codeMike Frysinger57-35/+156
Every arch handles this the same way, so move it to the common code. This will also make unifying the sim_cpu structure easier.

2021-04-09[sim,rx] Silence warning that turns into a build errorLuis Machado1-1/+1
On a 32-bit build, I ran into the following: sim/rx/fpu.c:789:6: error: "*((void *)&a+8)" may be used uninitialized in this function [-Werror=maybe-uninitialized] rv = fp_implode (&a); To silence this, just initialize the struct with 0's. sim/rx/ChangeLog: 2021-04-09 Luis Machado <luis.machado@linaro.org> * fpu.c (rxfp_itof): Initialize structure.
2021-04-08Avoid sequence point warning in h8300 simTom Tromey2-1/+6
GCC gives a -Wsequence-point warning for this code in the h8300 sim. The bug is that memory_size is both assigned and used in the same expression. The fix is to assign after the print. sim/h8300/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * compile.c (init_pointers): Fix sequence point warning.
2021-04-08Add system includes in simTom Tromey20-0/+48
This updates various parts of the sim to include missing system headers. I made the includes unconditional, because other parts of the tree are already doing this. 2021-04-08 Tom Tromey <tom@tromey.com> * traps.c: Include stdlib.h. * cris-tmpl.c: Include stdlib.h. sim/erc32/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * func.c: Include sys/time.h. sim/frv/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * traps.c: Include stdlib.h. * registers.c: Include stdlib.h. * profile.c: Include stdlib.h. * memory.c: Include stdlib.h. * interrupts.c: Include stdlib.h. * frv.c: Include stdlib.h. * cache.c: Include stdlib.h. sim/iq2000/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * iq2000.c: Include stdlib.h. sim/m32r/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * traps.c: Include stdlib.h. * m32r.c: Include stdlib.h. sim/ppc/ChangeLog 2021-04-08 Tom Tromey <tom@tromey.com> * emul_unix.c: Include time.h.

2021-04-08Fix DTB generation mechanism and build failureLuis Machado3-3/+19
I ran into a build failure with --enable-targets=all due to the fact that the moxie sim expects to be able to use the dtc tool. If it isn't available, the builds fails. The following patch adds a prebuilt dtb file to the tree. That file is the one that is used for installations. The patch also enables (re-)generation of the dtb file through maintainer mode, if it needs to be updated due to a change in the dts file. Tested on aarch64-linux/x86_64-linux. sim/moxie/ChangeLog: 2021-04-08 Luis Machado <luis.machado@linaro.org> * Makefile.in (moxie-gdb.dtb): Add maintainer mode dependency. (install-dtb): Install prebuilt dtb file. * moxie-gdb.dtb: New prebuilt file.
2021-04-08sim: set ASAN_OPTIONS=detect_leaks=0 when running igen and opc2cSimon Marchi11-16/+52
The igen/dgen and opc2c tools leak their heap-allocated memory (on purpose) at program exit, which makes AddressSanitizer fail the tool execution. This breaks the build, as it makes the tool return a non-zero exit code. Fix that by disabling leak detection through the setting of that environment variable. I also changed the opc2c rules for m32c to go through a temporary file. What happened is that the failing opc2c would produce an incomplete file (probably because ASan exits the process before stdout is flushed). This meant that further make attempts didn't try to re-create the file, as it already existed. A "clean" was therefore necessary. This can also happen in regular builds if the user interrupts the build (^C) in the middle of the opc2c execution and tries to resume it. Going to a temporary file avoids this issue. sim/m32c/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running opc2c. sim/mips/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen. sim/mn10300/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen. sim/ppc/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen. sim/v850/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen.

2021-04-08sim: testsuite: support exit 77 for unsupported testsMike Frysinger2-1/+8
Exit status 77 is common (including the autotools world) to indicate "skip this test". Add support for mapping that to "unsupported" as that's the closest in the dejagnu world.
2021-04-08sim: testsuite: skip tests when the port is disabledMike Frysinger2-0/+10
If the port hasn't been enabled, don't try to run its tests. Making this dynamic simplifies the test harnesses and avoids duplicating a bunch of target tuple checks.
2021-04-08sim: testsuite: calculate $arch from $subdirMike Frysinger72-180/+142
Since we require ports to use a matching subdir name in the testsuite tree, we can use that to calculate the $arch value.
2021-04-07Aarch64 sim fix for gcc-10 miscompilation.Jim Wilson2-2/+8
This fixes a problem that occurs when compiled by gcc-10, as the code is relying on undefined overflow behavior. This is fixed by replacing compares between 32-bit and 64-bit results with compares that just use the 64-bit results with a cast. PR sim/27483 * simulator.c (set_flags_for_add32): Compare uresult against itself. Compare sresult against itself.

2021-04-05Adjust location of readline in sim/erc32Tom Tromey3-2/+7
sim/erc32 uses an obsolete path to the in-tree build of readline. readline was moved into a subdirectory some time ago. This patch fixes the problem.

2021-04-03sim: example-synacor: a simple implementation for referenceMike Frysinger34-1/+16037
Provide a simple example simulator for people porting to new targets to use as a reference. This one has the advantage of being used by people and having a fun program available for it. It doesn't require a special target -- the example simulators can be built for any existing port.
2021-04-03sim: testsuite: integrate common tests into buildMike Frysinger7-71/+662
Now that we have the common automake build with support for build-time programs working, we can integrate the common tests into the default `make check` flow.
2021-04-03sim: add preliminary support for --enable-targetsMike Frysinger9-131/+389
This doesn't actually create one `run` program like other projects, but creates multiple `run-$arch` targets. While it might not seem that useful initially, this has some nice properties: - Allows us to quickly build all sim targets in a single tree. - Positions us better for converting targets over to a proper multitarget build+install. We don't have the ability to actually run tests against them, but that's due to a limitation in gas: it doesn't support multitarget. If that ever changes, we should be able to turn on our tests too. We can improve the test framework to fallback to a system toolchain if available to help mitigate that.
2021-04-02sim: igen: merge build into top levelMike Frysinger17-5489/+451
This simplifies the build a bit (especially for deps in port subdirs), and avoids recursive make. This in turn speeds up the build, and sets us up for multi-target.
2021-04-02sim: unify toolchain settingsMike Frysinger104-6382/+7842

2021-03-13sim: rename BUILD_LDFLAGS to LDFLAGS_FOR_BUILDMike Frysinger8-5/+31
The rest of the binutils tree renamed this variable many years ago.
2021-03-13sim: introduce {COMPILE,LINK}_FOR_BUILDMike Frysinger16-49/+111
These use the same pattern as seen in the opcodes/ dir and in automake in general (ish). This helps simplify the boilerplate for building and linking build-time code, and fixes some inconsistency in flag usage. For rules that were compiling+linking in a single step, split them into separate steps so we can apply the correct set of options. This matches automake behavior too.
2021-03-08Enable maintainer mode for simTom Tromey5-16/+80
The sim's recently switch to using Automake caused a build failure for me, because I didn't have the correct auto* tools in my path. However, the rule in the tree is that this is not needed in general. This patch adds a call to AM_MAINTAINER_MODE, to align the sim with the way the rest of the tree works here. sim/ChangeLog 2021-03-08 Tom Tromey <tromey@adacore.com> * aclocal.m4, configure, Makefile.in: Rebuild. * configure.ac: Use AM_MAINTAINER_MODE.
