2021-03-08sim: delete unused BUILD_LIBS settingMike Frysinger10-16/+38
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 Frysinger4-3/+9
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.
2021-03-07RegeneratedJeff Law2-6/+19
2021-03-07sim: testsuite: merge into toplevel automakeMike Frysinger11-201/+142
This allows us to delete most of our custom test logic, and avoids a recursive make for minor speed up.
2021-03-07sim: switch top level to automakeMike Frysinger10-520/+3101
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 Frysinger12-1125/+58
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 Frysinger4-122/+7
This package doesn't build any archives or install programs.
2021-02-28sim: igen: delete unused FOR_BUILD varsMike Frysinger4-24/+7
2021-02-28sim: set up build-time compiler settingsMike Frysinger32-277/+313
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 Frysinger32-93/+2793
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 Frysinger62-4206/+4359
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.
2021-02-28sim: delete unused SIM_EXTRA_LIBDEPSMike Frysinger6-8/+14
This was last used 15 years ago, so clearly not important enough to keep around. Punt it.
2021-02-27sim: delete redundant SIM_EXTRA_ALLMike Frysinger10-9/+26
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 Frysinger144-1197/+2156
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.
2021-02-20sim: merge configure.tgt into configure.acMike Frysinger4-324/+207
One fewer file to worry about & manage.

2021-02-13sim: testsuite: push $arch out to targetsMike Frysinger73-45/+274
This is needed to move to automake & its dejagnu-provided logic, and eventually by the unified sim logic. The $arch is used only to figure out which `run` program to use when running tests, and as we move to a single top-level build, we can delete this and use sim/run directly.
2021-02-13sim: rx: mitigate fread warningMike Frysinger2-2/+8
Current toolchains warn about unused result from fread, so mitigate the edge case if fread returns short data. It's not great, but it gets things building again.
2021-02-13sim: switch to AC_CONFIG_MACRO_DIRSMike Frysinger132-58741/+1168
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.
2021-02-13sim: common: delete unused aclocal.m4Mike Frysinger2-15/+4
This was missed when we deleted the common/configure build logic.
2021-02-08sim/rx: enable build with warningsAndrew Burgess3-1/+8
The rx simulator now has no build warnings. Delete the call to SIM_AC_OPTION_WARNINGS in configure.ac, the default yes will be provided by SIM_AC_OUTPUT. sim/rx/ChangeLog: * configure: Regenerate. * configure.ac (SIM_AC_OPTION_WARNINGS): Delete call.
2021-02-08sim/rx: avoid pointer arithmetic on void * pointersAndrew Burgess3-6/+18
Pointer arithmetic on void * pointers results in a GCC warning. Avoid the warning by casting the pointer to its actual type earlier in the function. sim/rx/ChangeLog: * mem.c (mem_put_blk): Rename parameter, add cast from parameter type to local type. Remove cast later in the function. (mem_get_blk): Likewise. * mem.h (mem_put_blk): Rename parameter to match definition. (mem_get_blk): Likewise.
2021-02-08sim/rx: add some missing includesAndrew Burgess3-2/+8
In load.c there's some GCC warnings about undefined functions (bfd_get_elf_phdr_upper_bound and bfd_get_elf_phdrs). To get the declarations of these functions include 'elf-bfd.h'. This headers also pulls in other elf related headers, like 'elf/internal.h' and 'elf/common.h', so these no longer need to be explicitly included from load.c. In trace.c and include for trace.h is missing, again this results in GCC warnings for missing function declarations. sim/rx/ChangeLog: * load.c: Replace 'elf/internal.h' and 'elf/common.h' includes with 'elf-bfd.h' include. * trace.c: Add 'trace.h' include.
2021-02-08sim/rx: use PRIx64 in printf format stringAndrew Burgess2-2/+7
Silence a GCC compiler warning by using PRIx64 in printf format string instead of hard coded "llx". sim/rx/ChangeLog: * reg.c (trace_register_changes): Use PRIx64 in printf format string.
2021-02-08sim/rx: move some variable declarations to the start of the blockAndrew Burgess3-3/+11
For sim code variables still need to be declared at the start of the enclosing block. This silences a few GCC warnings. sim/rx/ChangeLog: * syscalls.c (rx_syscall): Move declaration of some variables to the start of the enclosing block. * trace.c (load_file_and_line): Likewise.
2021-02-08sim/rx: provide a format string for printfAndrew Burgess2-4/+9
Calling printf with the format being a non constant string results in a GCC warning: warning: format not a string literal and no format arguments [-Wformat-nonliteral] Provide a constant format string to printf in the few places this warning is triggered. sim/rx/ChangeLog: * reg.c (fpsw2str): Provide a format string to printf. (trace_register_changes): Likewise.
2021-02-08sim/rx: delete an unused functionAndrew Burgess2-9/+4
This function is not used. sim/rx/ChangeLog: * err.c (execution_error_exit_all): Delete.
2021-02-08sim/rx: mark some functions as staticAndrew Burgess4-3/+9
Some functions that should be marked static. sim/rx/ChangeLog: * fpu.c (check_exceptions): Make static. * gdb-if.c (handle_step): Likewise. * mem.c (mem_put_byte): Likewise.
2021-02-08sim/rx: fill in missing 'void' for empty argument listsAndrew Burgess7-9/+21
Ensure we have 'void' inside empty argument lists. This was causing several warnings for the rx simulator. sim/rx/ChangeLog: * cpu.h (trace_register_changes): Add void parameter type. * err.c (ee_overrides): Likewise. * mem.c (mem_usage_stats): Likewise. (e): Likewise. * reg.c (stack_heap_stats): Likewise. * rx.c (pop): Likewise. (poppc): Likewise. (decode_opcode): Likewise. * syscalls.c (arg): Likewise.
2021-02-08sim/rx: fix an issue where we try to modify a const stringAndrew Burgess2-2/+6
While experimenting with switching on warnings for the rx simulator I discovered this bug. In sim_do_command we get passed a 'const char *' argument. We create a copy of this string to work with locally, but then while processing this we accidentally switch back to reference the original string. sim/rx/ChangeLog: * gdb-if.c (sim_do_command): Work with a copy of the command.
2021-02-08sim/rx: define sim_memory_mapAndrew Burgess2-0/+12
The rx simulator doesn't define sim_memory_map and so fails to link with GDB. Define it now to return NULL, this can be extended later to return an actual memory map if anyone wants this functionality. sim/rx/ChangeLog: * gdb-if.c (sim_memory_map): New function.
2021-02-06sim: erc32/m32c/rl78: add sim_memory_map stub for gdbMike Frysinger6-0/+30
These ports don't use the common sim core, so they weren't providing a sim_memory_map for gdb, so they failed to link with the new memory map logic added for the sim. Add stubs to fix.
2021-02-06sim: watchpoints: use common sim_pc_getMike Frysinger25-54/+129
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: add ChangeLog entries for last commitsMike Frysinger2-0/+12
2021-02-06sim: igen: drop libiberty linkageMike Frysinger3-10/+1
This dir doesn't use anything from libiberty, so drop the linkage.
2021-02-06sim: common: switch AC_CONFIG_HEADERSMike Frysinger31-92/+61
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 Frysinger73-233/+434
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.
2021-02-04gdb: riscv: enable sim integrationMike Frysinger2-0/+76
Now the simulator can be loaded via gdb using "target sim".
2021-02-04sim: riscv: new portMike Frysinger23-0/+18290
This is a hand-written implementation that should have fairly complete coverage for the base integer instruction set ("i"), and for the atomic ("a") and integer multiplication+division ("m") extensions. It also covers 32-bit & 64-bit targets. The unittest coverage is a bit weak atm, but should get better.
2021-01-31sim: cgen-trace: tweak printf callMike Frysinger2-1/+5
GCC warns that we pass a non-string literal as the format string, so add an explicit "%s" to make it happy.
2021-01-31sim: bpf: fix mainloop extract callMike Frysinger2-1/+5
The extract function takes the argbuf, not the scache.
2021-01-31sim: bpf/or1k: fix CGEN_TRACE_EXTRACT nameMike Frysinger5-127/+138
We renamed these years ago, but it looks like the cgen core missed the TRACE_EXTRACT function, so these new ports still used the incompatible common name. Fix those ports to use the right func.
2021-01-31sim: cgen-accfp: Fix pointer sign warningsStafford Horne2-3/+9
When compiling we get the following warnings: common/cgen-accfp.c: In function 'fixsfsi': common/cgen-accfp.c:370:18: warning: pointer targets in passing argument 1 of 'sim_fpu_to32i' differ in signedness [-Wpointer-sign] sim_fpu_to32i (&res, &op1, sim_fpu_round_near); ^ common/cgen-accfp.c: In function 'fixdfsi': common/cgen-accfp.c:381:18: warning: pointer targets in passing argument 1 of 'sim_fpu_to32i' differ in signedness [-Wpointer-sign] sim_fpu_to32i (&res, &op1, sim_fpu_round_near); ^
2021-01-31sim: v850: cleanup build warningsMike Frysinger4-107/+124
This port only had one minor warning left in it, so fix it and then enable -Werror behavior by deleting the macro call. We'll use the common default now (which is -Werror).
2021-01-31sim: v850: fix handling of SYS_timesMike Frysinger2-2/+5
My recent rewrite of the nltvals generator fixed a bug where SYS_times was not being exported for v850. But that in turn uncovered this bug where the SYS_times codepath had a compile error.
2021-01-31sim: moxie: cleanup build warningsMike Frysinger4-6/+22
This port only had one minor warning left in it, so fix it and then enable -Werror behavior by deleting the macro call. We'll use the common default now (which is -Werror).
2021-01-30sim: common: change gennltvals helper to PythonMike Frysinger6-240/+243
This tool is only run by developers and not in a release build, so rewrite it in Python to make it more maintainable.
2021-01-30sim: m68hc11: fix printf size warningsMike Frysinger2-1/+5
GCC complains %llu is wrong for signed64, so switch to PRIi64.
2021-01-30sim: m68hc11: localize a few functionsMike Frysinger2-6/+12
These are only used in this file and lack prototypes, so gcc complains about it. Add static everywhere to clean that up.
2021-01-30sim: m68hc11: tweak printf-style funcsMike Frysinger2-2/+6
GCC complains that we past non-string literals to a printf style func, so put a %s in here to keep it quiet.
