2021-06-16sim: drop arch-specific config.hMike Frysinger3-280/+47
All of the settings in here are handled by the common top-level config.h, so drop the individual arch-config.h files entirely. This will also help guarantee that we don't add any new arch specific defines that would affect common code which will help with the effort of unifying them.
2021-06-15sim: move dv-sockser define to CPPFLAGSMike Frysinger3-8/+5
This is the only define left in m4/ that is not in the common config.h, so move it to sim_hw_cflags so we can drop the arch-specific config.h.
2021-06-12sim: overhaul alignment settings managementMike Frysinger4-56/+8
Currently, the sim-config module will abort if alignment settings haven't been specified by the port's configure.ac. This is a bit weird when we've allowed SIM_AC_OPTION_ALIGNMENT to seem like it's optional to use. Thus everyone invokes it. There are 4 alignment settings, but really only 2 matters: strict and nonstrict. The "mixed" setting is just the default ("unset"), and "forced" isn't used directly by anyone (it's available as a runtime option for some ports). The m4 macro has 2 args: the "wire" settings (which represents the hardwired port behavior), and the default settings (which are used if nothing else is specified). If none are specified, then the build won't work (see above as if SIM_AC_OPTION_ALIGNMENT wasn't called). If default settings are provided, then that is used, but we allow the user to override at runtime. Otherwise, the "wire" settings are used and user runtime options to change are ignored. Most ports specify a default, or set the "wire" to nonstrict. A few set "wire" to strict, but it's not clear that's necessary as it doesn't make the code behavior, by default, any different. It might make things a little faster, but we should provide the user the choice of the compromises to make: force a specific mode at compile time for faster runtime, or allow the choice at runtime. More likely it seems like an oversight when these ports were initially created, and/or copied & pasted from existing ports. With all that backstory, let's get to what this commit does. First kill off the idea of a compile-time default alignment and set it to nonstrict in the common code. For any ports that want strict alignment by default, that code is moved to sim_open while initializing the sim. That means WITH_DEFAULT_ALIGNMENT can be completely removed. Moving the default alignment to the runtime also allows removal of setting the "wire" settings at configure time. Which allows removing of all arguments to SIM_AC_OPTION_ALIGNMENT and moving that call to common code. The macro logic can be reworked to not pass WITH_ALIGNMENT as -D CPPFLAG and instead move it to config.h. All of these taken together mean we can hoist the macro up to the top level and share it among all sims so behavior is consistent among all the ports.
2021-06-12sim: unify bug & package settingsMike Frysinger3-87/+2
Move these options up to the common dir so we only test & export them once across all ports. The AC_INIT macro does a lot of the heavy lifting already which allows further simplification.
2021-06-12sim: unify debug/stdio/trace/profile build settingsMike Frysinger2-150/+2
Move these options up to the common dir so we only test & export them once across all ports. The ppc code needs a little extra care with its trace settings as it's not exactly the same API as the common code. The other knobs are the same though.
2021-06-12sim: unify environment build settingsMike Frysinger3-32/+2
Move the --sim-enable-environment option up to the common dir so we only test & export it once across all ports.
2021-06-12sim: unify assert build settingsMike Frysinger4-28/+6
Move the --sim-enable-assert option up to the common dir so we only test & export it once across all ports.
2021-06-12sim: unify platform function & header testsMike Frysinger4-574/+7
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.
2021-06-08sim: igen: harmonize tool variablesMike Frysinger2-15/+20
Separate the name of the igen program from the options used to run it. This allows us to avoid duplicating ../igen/igen in Makefiles and reuse the existing setting in the common Makefile. This also allows us to easily harmonize the use of EXEEXT between igen/local.mk and the common makefiles when cross-compiling for e.g. Windows.
2021-05-29sim: mips: fix build w/out dv-sockserMike Frysinger2-3/+9
Make sure we don't fail to build when dv-socker is unavailable.
2021-05-22sim: mips: Add shadow mappings for 32-bit memory address spaceFaraz Shahbazker2-3/+17
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. 2021-05-04 Faraz Shahbazker <fshahbazker@wavecomp.com> sim/mips/ChangeLog: * interp.c (sim_open): Add shadow mappings from 32-bit address space to 64-bit sign-extended address space.
2021-05-22sim: mips: Only truncate sign extension bits for 32-bit target modelsFaraz Shahbazker2-6/+11
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.

2021-05-17sim: fully merge sim_state_base into sim_stateMike Frysinger2-2/+4
Now that all ports have migrated to the new framework, drop support for the old sim_state_base layout.
2021-05-17sim: mips: invert sim_state storageMike Frysinger5-27/+27
2021-05-16sim: switch config.h usage to defs.hMike Frysinger12-4/+36
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.
2021-05-16sim: riscv: move __int128 check to configureMike Frysinger3-2/+19
2021-05-14sim: create header namespaceMike Frysinger2-2/+6
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.
2021-05-04sim: mips: include stdlib.h for memory prototypesMike Frysinger2-0/+5
This file uses free() and friends, so include it to fix missing prototype warnings.
2021-05-04sim: mips: always enable device modelsMike Frysinger3-18/+8
There's no need to restrict these to only specific targets as the user can select them at runtime if they want them. Always build them so we can improve build coverage too.
2021-05-04sim: mips: delete unused constant variablesMike Frysinger4-29/+10
Since these never change, inline and delete them.
2021-05-04sim: mips: fix qh_acc tableMike Frysinger2-1/+5
The AccAddLQH func was unused, and looking at this table, it looks like it's due to a typo.
2021-05-04sim: add support for build-time ar & ranlibMike Frysinger2-2/+14
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.
2021-05-01sim: mips: mark local func staticMike Frysinger2-1/+5
2021-05-01sim: nrun: add local strsignal prototypeMike Frysinger3-2/+12
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.
2021-04-23sim: simplify hardware m4 macroMike Frysinger3-13/+11
Every port using this sets the 1st arg to yes and the 2nd arg to "". These are the defaults we probably want anyways in order to unify the codebase, so move them to the macro and only allow ports to declare extra hardware models.
2021-04-22Do not check for sys/time.h or sys/times.hTom Tromey3-14/+6
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. sim/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * m4/sim_ac_common.m4 (SIM_AC_COMMON): Don't check for sys/time.h or sys/times.h. sim/aarch64/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/arm/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/avr/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/bfin/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/bpf/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * sim-utils.c: Update includes. sim/cr16/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * simops.c: Update includes. * configure, config.in: Rebuild. sim/cris/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * rvdummy.c: Update includes. * dv-rv.c: Update includes. * configure, config.in: Rebuild. sim/d10v/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/erc32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/example-synacor/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/frv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/ft32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/h8300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/iq2000/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/lm32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m32c/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m32r/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m68hc11/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mcore/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/microblaze/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mips/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mn10300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/moxie/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/msp430/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/or1k/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/ppc/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * mon.c: Update includes. * emul_unix.c: Update includes.

Some spots in the sim build used manual dependencies, and some spots did a compilation by hand but did not use the automatic dependency tracking code. This patch fixes these spots.

2021-04-21sim: use -Werror when probing for supported warning flagsSimon Marchi2-1/+5
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.

2021-04-12sim: cgen: move cgen_cpu_max_extra_bytes logic into the common codeMike Frysinger2-1/+5
Every arch handles this the same way, so move it to the common code. This will also make unifying the sim_cpu structure easier.
2021-04-08sim: set ASAN_OPTIONS=detect_leaks=0 when running igen and opc2cSimon Marchi2-10/+14
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.

2021-04-04sim: mips: Add handlers to simulator monitor for unlink, lseek and statFaraz Shahbazker2-1/+75
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>
2021-04-02sim: igen: merge build into top levelMike Frysinger2-7/+5
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 Frysinger3-153/+162
The toplevel, common, and igen dirs all have their own code for setting up toolchain settings. Unify all of that in a new macro.
2021-02-28sim: set up build-time compiler settingsMike Frysinger1-9/+10
Some sim dirs were already setting up CFLAGS_FOR_BUILD in inconsistent ways. Move it to a common place for reuse.
2021-02-28sim: use AC_CHECK_TOOL to find arMike Frysinger1-3/+93
Rather than require $AR be set and then default to `ar`, use the standard AC_CHECK_TOOL helper to find a good prefixed tool. In practice this shouldn't change much as we seem to have macros in the tree that were already setting it up, but we shouldn't rely on that implicitly.
2021-02-28sim: require AC_PROG_CPP explicitlyMike Frysinger2-140/+145
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.
2021-02-27sim: delete redundant SIM_EXTRA_ALLMike Frysinger2-1/+6
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.
2021-02-21sim: common: split up acinclude.m4 into individual m4 filesMike Frysinger4-5/+32
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.
2021-02-13sim: switch to AC_CONFIG_MACRO_DIRSMike Frysinger4-1834/+35
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.
2021-02-06sim: watchpoints: use common sim_pc_getMike Frysinger2-1/+4
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.
2021-02-06sim: common: switch AC_CONFIG_HEADERSMike Frysinger1-3/+2
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.
2021-02-06sim: drop use of bfd/configure.hostMike Frysinger2-7/+15
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.
2021-01-30sim: watchpoints: change sizeof_pc to sizeof(sim_cia)Mike Frysinger2-1/+4
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.
2021-01-11sim: clean up C11 header includesMike Frysinger4-24/+37
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.
2021-01-09sim: clean up stale AC_PREREQ refsMike Frysinger2-14/+7
This was purged from the tree when we upgraded to autoconf-2.69, but a few references in the sim tree were missed.
2021-01-09sim: enable -Werror by default for some archesMike Frysinger3-6/+6
We've had this off for a long time because the sim code was way too full of warnings for it to be feasible. However, I've cleaned things up significantly from when this was first merged, and we can start to turn this around. Change the macro to enable -Werror by default, and allow ports to opt out. New ports will get it automatically (and we can push back on them if they try to turn it off). Also turn it off for the few ports that still hit warnings for me. All the rest will get the new default, and we'll wait for feedback if/when new issues come up.
