2021-08-17sim: rename ChangeLog files to ChangeLog-2021Mike Frysinger1-1397/+0
Now that ChangeLog entries are no longer used for sim patches, this commit renames all relevant sim ChangeLog to ChangeLog-2021, similar to what we would do in the context of the "Start of New Year" procedure. The purpose of this change is to avoid people merging ChangeLog entries by mistake when applying existing commits that they are currently working on. Also throw in a .gitignore entry to keep people from adding new ChangeLog files anywhere in the sim tree.
2021-06-09sim: cleanup obsolete NULL fallbackMike Frysinger1-0/+7
We require C11 which defines NULL, so drop the inconsistent set of fallback defines in the codebase.
2021-06-05sim: common: start dedicated local.mkMike Frysinger1-0/+5
This provides a space to generate things that we only need to build once per-arch. Some day that will be all of common/, but for now, we move the version.c management in.
2021-05-04sim: add support for build-time ar & ranlibMike Frysinger1-0/+4
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.
2021-05-02sim: replace custom attributes with ansidecl.hMike Frysinger1-0/+5
A lot of this code predates the common attributes. We had already started migrating over piece by piece, so just do a pass across all the attributes and replace most of them.
2021-04-02sim: igen: merge build into top levelMike Frysinger1-0/+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 Frysinger1-0/+8
The toplevel, common, and igen dirs all have their own code for setting up toolchain settings. Unify all of that in a new macro.
2021-03-13sim: rename BUILD_LDFLAGS to LDFLAGS_FOR_BUILDMike Frysinger1-0/+8
The rest of the binutils tree renamed this variable many years ago.
2021-03-13sim: introduce {COMPILE,LINK}_FOR_BUILDMike Frysinger1-0/+7
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.
2021-03-08sim: delete unused BUILD_LIBS settingMike Frysinger1-0/+5
This hasn't been initialized anywhere for years. It used to be for passing in the path to libiberty, but that stopped happening long ago. Delete it to simplify the build logic.
2021-03-07sim: igen: update options APIMike Frysinger1-0/+6
This local macro doesn't take any args, so adjust the API to match. No one really noticed as this is behind code that is not normally built, only when a dev specifically tries to compile it.
2021-03-07sim: switch top level to automakeMike Frysinger1-0/+4
This doesn't gain us much by itself, but it sets us up for using more features as we try to unify ports and avoid recursive make.
2021-02-28sim: igen: drop config.h & header checkingMike Frysinger1-0/+14
While the configure script was checking for a bunch of headers, only one of them was conditionally included in the source (unistd.h). The rest were always included. Based on those usage this whole time, we can reasonably assume that the build also has unistd.h. All the other files including config.h never actually used any defines from the header.
2021-02-28sim: igen: delete more unused toolchain settingsMike Frysinger1-0/+7
This package doesn't build any archives or install programs.
2021-02-28sim: igen: delete unused FOR_BUILD varsMike Frysinger1-0/+7
2021-02-21sim: common: split up acinclude.m4 into individual m4 filesMike Frysinger1-0/+5
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 Frysinger1-0/+5
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: add ChangeLog entries for last commitsMike Frysinger1-0/+7
2021-02-06sim: drop use of bfd/configure.hostMike Frysinger1-0/+5
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.
2021-01-11sim: clean up C11 header includesMike Frysinger1-0/+11
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: enable -Werror by default for some archesMike Frysinger1-0/+4
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.
2021-01-04sim: include stdlib.h for atoi()Mike Frysinger1-0/+4
Make sure the files using atoi() include stdlib.h for its prototype. These files were relying on it being included implicitly by others which isn't guaranteed, and newer toolchains produce warnings.
2021-01-04sim: update bug URI to https://Mike Frysinger1-0/+4
2020-07-03sim/igen: Fix linker error with -fno-commonSebastian Huber1-0/+9
GCC 10 enables -fno-common by default. This resulted in multiple definition linker errors since a global variable was declared and defined in a header file: ld: libsim.a(idecode.o):sim/v850/idecode.h:71: multiple definition of `idecode_issue'; libsim.a(irun.o):sim/v850/idecode.h:71: first defined here ld: libsim.a(engine.o):sim/v850/idecode.h:71: multiple definition of `idecode_issue'; libsim.a(irun.o):sim/v850/idecode.h:71: first defined here ld: libsim.a(support.o):sim/v850/idecode.h:71: multiple definition of `idecode_issue'; libsim.a(irun.o):sim/v850/idecode.h:71: first defined here ld: libsim.a(semantics.o):sim/v850/idecode.h:71: multiple definition of `idecode_issue'; libsim.a(irun.o):sim/v850/idecode.h:71: first defined here sim/igen PR sim/26194 * lf.h (lf_get_file_type): Declare. * lf.c (lf_get_file_type): Define. * gen-idecode.c (print_idecode_issue_function_header): Use lf_get_file_type() to issue an extern variable declaration in case of header files.

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 inline configure option everywhereMike Frysinger1-0/+4
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.
2016-01-04sim: 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.
2015-07-24Remove leading/trailing white spaces in ChangeLogH.J. Lu1-40/+40
2015-06-12sim: update configure.in->configure.ac docsMike Frysinger1-0/+4
A few places still refer to the configure.in file; update them.

2015-04-17sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET}Mike Frysinger1-0/+5
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.
2015-04-01sim: 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.

2014-03-04sim: convert old style prototypesMike Frysinger1-0/+4
Most of these prototypes have been killed off, but we have a few left in the sim tree. Clean them up so we can enable the -W flag for it.

2012-03-24[PATCH] sim: make sure to include strsignal prototypeMike Frysinger1-0/+4
Before POSIX standardized strsignal(), old systems would hide the prototype unless the normal extension defines were enabled. So use the AC_USE_SYSTEM_EXTENSIONS helper for that. Then make sure we include string.h ourselves in nrun.c rather than relying on implicit includes via other sim headers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-18sim: rename common/aclocal.m4 to common/acinclude.m4Mike Frysinger1-0/+4
Automake likes to dump macros automatically used into the aclocal.m4 file, but the common/aclocal.m4 naming prevents that. So rename it to the more normal "acinclude.m4" so the aclocal tool can work. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-18sim: move from common.m4 to SIM_AC_COMMONMike Frysinger1-0/+6
Now that the sourceware tree generally requires autoconf-2.64, update the sim tree to require that too. This allows us to drop the long standing SIM_AC_COMMON/common.m4 workaround as autoconf 2.64+ seems to work for me. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-02-14sim: punt zfree()Mike Frysinger1-0/+4
The sim keeps track of which allocations are zero-ed internally (via zalloc) and then calls a helper "zfree" function rather than "free". But this "zfree" function simply calls "free" itself. Since I can see no point in this and it is simply useless overhead, punt it. The only real change is in hw-alloc.c where we remove the zalloc_p tracking, and sim-utils.c where zfree is delete. The rest of the changes are a simple `sed` from "zfree" to "free". Signed-off-by: Mike Frysinger <vapier@gentoo.org>
