2017-02-13sim: use ARRAY_SIZE instead of ad-hoc sizeof calculationsMike Frysinger1-0/+6
2016-04-10Fix primary reason why the SH simulation hasn't been working on 64 bit hosts.Oleg Endo1-1/+7
sim/sh/ * interp.c (dmul): Split into dmul_s and dmul_u. Use explicit integer width types and simplify implementation. * gencode.c (dmuls.l, dmulu.l): Use new functions dmul_s and dmul_u.
2016-04-10Move ChangeLog entries from sim/ChangeLog to sim/sh/ChangeLog.Oleg Endo1-0/+5
2016-01-10sim: move many common settings from CPPFLAGS to config.hMike Frysinger1-0/+4
Rather than stuffing the command line with a bunch of -D flags, start moving things to config.h which is managed by autoheader. This makes the makefile a bit simpler and the build output tighter, and it makes the migration to automake easier as there are fewer vars to juggle. We'll want to move the other options out too, but it'll take more work.
2016-01-10sim: drop unused SIM_AC_OPTION_PACKAGESMike Frysinger1-0/+4
This was imported from the ppc sim, but that was only used to control a single file, and that is already governed by the hw models. There's no need to have a sep configure option here, especially since none of the other sims are using it. Even when the code is enabled, there's no runtime overhead.
2016-01-10sim: allow the environment configure option everywhereMike Frysinger1-0/+5
Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: allow the assert configure option everywhereMike Frysinger1-0/+4
Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order to make the configure flag available, which none of them do. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports.
2016-01-10sim: drop targ-vals.def->nltvals.def indirectionMike Frysinger1-0/+4
We don't have alternative nltvals.def files, so always symlinking the targ-vals.def file to it doesn't gain us anything. It does make the build more complicated though and a pain to convert to something newer (like automake). Drop the symlinking entirely. In the future, we'll want to explode this file anyways into the respective arch dirs so things can be selected dynamically at runtime, so it's not like we'll be bringing this back.
2016-01-10sim: allow the inline configure option everywhereMike Frysinger1-0/+5
Currently ports have to call SIM_AC_OPTION_INLINE explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: drop --enable-sim-{regparm,stdcall} optionsMike Frysinger1-0/+4
These options were never exposed for most sims (just the ppc one), and they are really only useful on 32-bit x86 systems. Considering modern systems tend to be 64-bit x86_64 and how well modern compilers are at optimizing code, these have outlived their usefulness.
2016-01-10sim: drop --enable-sim-cflags optionMike Frysinger1-0/+4
No other sub directory provides such a configuration option, so drop it from the sim dir as well. This cleans up a good bit of code in the process. If people want to use custom flags for just the sim, they can still run configure+make by hand in the sim subdir and use the normal CFLAGS settings.
2016-01-09sim: drop common/cconfig.h in favor of a single config.hMike Frysinger1-0/+4
The common subdir sets up a cconfig.h file to hold checks for the common code. In practice, most files still end up using config.h instead which just leads to confusion. Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON so we can drop the cconfig.h file altogether. Now there is only a single config.h file like normal.
2016-01-06sim: sim_{create_inferior,open,parse_args}: constify argv/env slightlyMike Frysinger1-0/+5
2016-01-03 Mike Frysinger <vapier@gentoo.org> * sim-options.c (sim_parse_args): Mark argv array const. * sim-options.h (sim_parse_args): Likewise.
2016-01-04sim: punt x86-specific bswap logicMike Frysinger1-0/+4
The compiler/C library should produce reasonable code for htonl/ntohl, and at least glibc tries pretty hard to always produce good code for them. This logic only had support for 32-bit x86 systems anymore, and it's unlikely people were even opting into this, so drop it all.
2016-01-03sim: parse_args: display getopt error ourselvesMike Frysinger1-0/+4
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.
2016-01-03sim: use libiberty countargv in more placesMike Frysinger1-0/+5
A bunch of places open code the countargv implementation, or outright duplicate it (as count_argc). Replace all of those w/countargv.
2016-01-03sim: drop host endian configure optionMike Frysinger1-0/+7
The --enable-sim-hostendian flag was purely so people had an escape route for when cross-compiling. This is because historically, AC_C_BIGENDIAN did not work in those cases. That was fixed a while ago though, so we can require that macro everywhere now and simplify a good bit of code.
2016-01-03sim: convert to bfd_endianMike Frysinger1-0/+7
Rather than re-invent endian defines, as well as maintain our own list of OS & arch-specific includes, punt all that logic in favor of the bfd ones already set up and maintained elsewhere. We already rely on the bfd library, so leveraging the endian aspect should be fine.
2015-12-30sim: arm/d10v/h8300/m68hc11/microblaze/mips/mn10300/moxie/sh/v850: convert ↵Mike Frysinger1-0/+8
to common sim_{fetch,store}_register
2015-12-27sim: unify sim-hloadMike Frysinger1-0/+4
Pretty much all targets are using this module already, so add it to the common list of objects. The only oddball out here is cris and that's because it supports loading via an offset for all the phdrs. We drop support for that.
2015-12-26sim: punt WITH_DEVICES & tconfig.h supportMike Frysinger1-0/+4
No arch is using this anymore, and we want all new ports using the hardware framework instead. Punt WITH_DEVICES and the two callbacks device_io_{read,write}_buffer. We can also punt the tconfig.h file as no port is using it anymore. This fixes in-tree builds that get confused by picking up the wrong one (common/ vs <port>/) caused by commit ae7d0cac8ce971f7108d270c. Any port that needs to set up a global define can use their own sim-main.h file that they must provide regardless.
2015-11-22sim: sh: delete global callback/argvMike Frysinger1-0/+16
We can use the sim state everywhere now to get these values on the fly.
2015-11-16sim: sim-stop/sim-reason/sim-reg: move to common obj listMike Frysinger1-0/+4
Now that all arches (for the most part) have moved over, move sim-stop.o, sim-reason.o, and sim-reg.o to the common object list and out of all the arch ports.
2015-11-15sim: sim-close: unify sim_close logicMike Frysinger1-0/+4
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.
2015-07-24Remove leading/trailing white spaces in ChangeLogH.J. Lu1-38/+38
2015-06-23sim: use AS_HELP_STRING everywhereMike Frysinger1-0/+4
This helps standardize the configure --help output.
2015-06-12sim: update configure.in->configure.ac docsMike Frysinger1-0/+4
A few places still refer to the configure.in file; update them.
2015-06-12sim: drop -DTRACE from configureMike Frysinger1-0/+4
No code uses this anymore and the symbol conflicts with the new TRACE helper. Punt it from configure.
2015-04-18sim: unify SIM_CPU definitionMike Frysinger1-0/+4
Since every target typedefs this the same way, move it to the common code. We have to leave Blackfin behind here for now because of inter-dependencies on types and headers: sim-base.h includes sim-model.h which needs types in machs.h which needs types in bfim-sim.h which needs SIM_CPU.
2015-04-18sim: unify sim_cia definitionMike Frysinger1-0/+4
Almost every target defines sim_cia the same way -- either using the address_word type directly, or a type of equivalent size. The only odd one out is sh64 (who has 32bit address_word and 64bit cia), and even that case doesn't seem to make sense. We'll put off clean up though of sh64 and at least set up a sensible default for everyone.
2015-04-17sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET}Mike Frysinger1-0/+4
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.
2015-04-17sim: arm/cr16/d10v/h8300/microblaze/sh: fill out sim-cpu pc fetch/store helpersMike Frysinger1-0/+5
This makes the common sim-cpu logic work.
2015-04-15sim: unify sim-cpu usageMike Frysinger1-0/+5
Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the cpu state is multicore, and the STATE_CPU defines match, we can move it all to the common code.
2015-04-13sim: fix the PKGVERSION defineMike Frysinger1-0/+4
This should be SIM, not GDB.
2015-04-06sim: move sim-engine.o/sim-hrw.o to the common listMike Frysinger1-0/+4
This makes these two objects available to all sims by default.
2015-04-01sim: update zlib handlingMike Frysinger1-0/+4
With zlib being mandatory, and the updated m4 configs, we need to regen and use the new settings w/bfd to avoid linkage errors.
2015-03-28sim: sh: convert to nrunMike Frysinger1-0/+23
A lot of cpu state is stored in global variables, as is memory handling. The sim_size support needs unwinding at some point. But at least this is an improvement on the status quo.
2015-03-28sim: sh: clean up some warningsMike Frysinger1-0/+32
Mostly converting old style prototypes. Also include a few missing headers, and add static/casts where appropriate.
2015-03-28sim: sh: fix broken handling in DSR regMike Frysinger1-0/+4
A missing */ caused a case statement to be incorrect masked out which also hide an error where the wrong value was being checked. Fix both.
2015-03-28sim: sh: clean up gencodeMike Frysinger1-0/+22
The build line was missing the normal BUILD_xxx flags. Once we added that, we get warnings that weren't shown before. As we fix those, we notice that the -d option segfaults because it tries to write readonly memory. Fix that too as part of the const/prototype clean up.
2015-03-28sim: sh: use common configure optionsMike Frysinger1-0/+7
In preparation for converting to nrun, call the common functions that are needed. This also produces a bunch of warnings, but one thing at a time.
2015-03-16sim: rename tconfig.in to tconfig.hMike Frysinger1-0/+6
Rather than manually include tconfig.h when we think we'll need it (which is error prone as it can define symbols we expect from config.h), have it be included directly by config.h. Since we know we have to include that header everywhere already, this will make sure tconfig.h isn't missed. It should also be fine as tconfig.h is supposed to be simple and only set up a few core defines for the target. This allows us to stop symlinking it in place all the time and just use it straight out of the respective source directory.
2015-03-14sim: make nrun the default run programMike Frysinger1-0/+6
We want people to stop using the run.c frontend, but it's hard to notice when it's still set as the default. Lets flip things so nrun.c is the default, and users of run.c will get an error by default. We turn that error into a warning for existing sims so we don't break them -- this is mostly meant for people starting new ports.
2015-03-14sim: drop duplicate header checksMike Frysinger1-0/+5
The SIM_AC_COMMON macro already checks for a bunch of headers, so specific sim ports need not do it themselves.
2014-11-28Correct fabs and fneg insns in simulatorOleg Endo1-0/+5
It seems that the implementation of the SH fabs and fneg insns in the simulator is not correct. They use the FP_UNARY macro which checks the FPSCR.PR setting and raises an exception if PR = 1 (double precision) and the register number is not even (i.e. a valid DF reg number). For normal unary FP insns this is fine. However, fneg and fabs perform the same (integer) operations regardless of the FPSCR.PR setting. This issue initially popped up here https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63260 I've checked some of the failing tests mentioned in GCC PR 63260 above with the patch applied and the failures go away. sim/sh/ChangeLog (tiny patch): * gencode.c (fabs, fneg): Implement as integer operation instead of using the FP_UNARY macro.

2014-08-19Fix --diable-shared --enable-plugins build breakageAlan Modra1-0/+4
Directories that don't use libtool need to add -ldl (on most *nix hosts) to provide dlopen for libbfd. config/ * plugins.m4 (AC_PLUGINS): If plugins are enabled, add -ldl to LIBS via AC_SEARCH_LIBS. gdb/ * acinclude.m4 (GDB_AC_CHECK_BFD): Don't add -ldl. * config.in: Regenerate. sim/ppc/ * configure.ac: Invoke AC_PLUGINS. * config.in: Regenerate. and regen lots of configure files.
2014-08-15Regenerate sim configury.Roland McGrath1-0/+5
2014-03-10sim: constify arg to sim_do_commandMike Frysinger1-0/+5
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.
