* Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker2022-01-011-1/+1
| | | | | | | | This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
* sim: split program path out of argv vectorMike Frysinger2021-11-151-4/+1
| | | | | | | | | | | | | | 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.
* sim: split sim-signal.h include outMike Frysinger2021-06-181-0/+1
| | | | | | | | 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.
* sim: overhaul & unify endian settings managementMike Frysinger2021-06-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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, the arch is expected to support both, and the value will be probed based on the user runtime options or the input program. Only two arches today set the default value (bpf & mips). We can probably let this go as it only shows up in one scenario: the sim is invoked, but with no inputs, and no user endian selection. This means bpf will not behave like the other arches: an error is shown and forces the user to make a choice. If an input program is used though, we'll still switch the default to that. This allows us to remove the WITH_DEFAULT_TARGET_BYTE_ORDER setting. For the ports that set a "wire" endian, move it to the runtime init of the respective sim_open calls. This allows us to change the WITH_TARGET_BYTE_ORDER to purely a user-selected configure setting if they want to force a specific endianness. With all the endian logic moved to runtime selection, we can move the configure call up to the common dir so we only process it once across all ports. The ppc arch was picking the wire endian based on the target used, but since we weren't doing that for other biendian arches, we can let this go too. We'll rely on the input selecting the endian, or make the user decide.
* sim: overhaul alignment settings managementMike Frysinger2021-06-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* sim: avr: invert sim_state storageMike Frysinger2021-05-171-6/+7

* sim: switch config.h usage to defs.hMike Frysinger2021-05-161-1/+2
| | | | | | | | | | | | | | 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.
* sim: create header namespaceMike Frysinger2021-05-141-1/+1
| | | | | | | 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.
* sim: cgen: move cgen_cpu_max_extra_bytes logic into the common codeMike Frysinger2021-04-121-1/+1
| | | | | 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: watchpoints: use common sim_pc_getMike Frysinger2021-02-061-6/+0
| | | | | | | | | | | | 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.
* sim: watchpoints: change sizeof_pc to sizeof(sim_cia)Mike Frysinger2021-01-301-1/+0
| | | | | | | | | | | | | | | 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.
* sim: clean up C11 header includesMike Frysinger2021-01-111-2/+1
| | | | | | | | | | | | 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.

* Update copyright year range in all GDB files.Joel Brobecker2019-01-011-1/+1
| | | | | | | | | | | | | | | | This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

| | | | | | | PR target/ 19401 * avr/interp.c (step_once): Pass break instruction address to sim_engine_halt function which writes that to PC. Remove code that follows that function call as it is unreachable.

* sim: parse_args: display getopt error ourselvesMike Frysinger2016-01-031-3/+1
| | | | | | 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.

* sim: avr: move global state to sim/cpu stateMike Frysinger2015-11-221-131/+132
| | | | | We don't want global variables in the sim as all state should be in the sim state or in the cpu state. This pushes down all that logic for avr.
* sim: avr: switch to common sim-regMike Frysinger2015-11-221-4/+6
| | | | | | This is not entirely useful as avr doesn't (yet) store its register state in the cpu state, but it does allow for switching to the common code for these functions.
* sim: sim-close: unify sim_close logicMike Frysinger2015-11-151-6/+0
| | | | | | | | | | | | | | | | 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.
* sim: avr/mcore/moxie: fill out sim-cpu pc fetch/store helpersMike Frysinger2015-04-161-0/+22
| | | | This makes the common sim-cpu logic work.
* sim: avr: convert to nrun.oMike Frysinger2015-03-281-831/+734
| | | | | Looks like a lot more work than actually was -- the main decode loop was de-indented by dropping the loop as a step-once function.
* sim: drop unused sim_kill functionMike Frysinger2015-02-191-6/+0

* sim: constify arg to sim_do_commandMike Frysinger2014-03-101-1/+1
| | | | | | It is rare for people to want to modify the cmd arg. In general, they really shouldn't be, but a few still do. For those who misbehave, dupe the string locally so they can bang on it.
* sim: constify prog_nameMike Frysinger2014-03-051-1/+1
| | | | | There's no need for the prog_name handed down to the core to be mutable, so add const markings to it and all the related funcs.
