2015-11-22sim: common: set up CPPFLAGS/CXXFLAGS/LDFLAGS from configure [PR sim/18762]Mike Frysinger2-0/+8
Make sure we pass down the CPP/CXX/LD flags that configure set up for us like we already do for C flags.
2015-11-22sim: sim_do_commandf: fix call to va_end [PR sim/19273]Mike Frysinger2-2/+13
Make sure we call va_end even in the error case.
2015-11-22sim: common: add PRI printf definesMike Frysinger2-0/+28
Keeping track of the right printf formats for the various types can be a pretty big hassle, especially in common code which has to support a variety of bitsizes. Take a page from the existing standards and add a set of PRI macros which hide the details in a common header.
2015-11-17sim: always enable modulo memoryMike Frysinger4-29/+14
Having this be a config option doesn't make sense: the code size is pretty much the same (as all the logic is still active), and if it's disabled, the sim throws an error if you try to use it. That means we can't break sims that weren't using it before by enabling it all the time.
2015-11-17sim: sim-close: use XCONCAT2 helperMike Frysinger2-3/+6
No point in open coding this logic when we've got nifty helpers to do it.
2015-11-16sim: sim-stop/sim-reason/sim-reg: move to common obj listMike Frysinger2-0/+8
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 Frysinger3-0/+63
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. Lu1-160/+160
2015-06-24sim: trace: drop unused trace_one_insnMike Frysinger3-98/+5
Everyone has migrated to the split functions (trace_prefix + trace_generic) a while ago, so we can drop this one now.
2015-06-24sim: trace: rename debug_printf fullyMike Frysinger3-5/+10
Rather than redirect using a define, just rename the symbol fully.
2015-06-24sim: trace: add a basic cpu register classMike Frysinger3-12/+44
The bfin/msp430 ports already had trace logic set up for reading/writing cpu registers, albeit using different unrelated levels (core & vpu). Add a proper register class for these and for other ports.
2015-06-24sim: trace: add set of system helpersMike Frysinger2-0/+28
Some code paths trace on a system instance and not a cpu instance (like the events code), so add some helpers for those cases.
2015-06-24sim: trace: document alu/fpu/vpu trace options betterMike Frysinger3-7/+14
Make the acronyms clear for people.
2015-06-23sim: common: replace SIM_FILTER_PATH with lbasenameMike Frysinger3-26/+16
This helper macro has largely the same behavior as libiberty's lbasename. There is a slight nuance related to colons, but it's not clear what the point of that is, and the code implies that it just wants the basename.
2015-06-23sim: use AS_HELP_STRING everywhereMike Frysinger3-31/+81
This helps standardize the configure --help output.
2015-06-23sim: trace: do not enable internal debug by defaultMike Frysinger2-2/+6
Since --trace-debug is for people hacking on the sim sources rather than people just using the sim, default it to off. This matches the behavior of other debug knobs we have.
2015-06-23sim: assume recentish compiler/systemsMike Frysinger3-26/+5
Assume the build system supports stdint.h/stdarg.h as those have been around long enough and we don't care about pre-stdc compilers anymore.
2015-06-21sim: common: add basic model assertMike Frysinger2-0/+5
If the configured in default doesn't match a known value, throw an assertion failure rather than segfaulting deeper down.
2015-06-21sim: common: use standard intXX_t types for signedXXMike Frysinger2-82/+27
Let's assume that the system supports the POSIX int8/16/32/64_t types as this collapses the logic significantly.
2015-06-21sim: common: standardize multiple include definesMike Frysinger6-13/+26
We use SIM_xxx_H in most headers, so convert _SIM_xxx_H_ over to it.
2015-06-18sim: syscall: simplify unknown syscall traceMike Frysinger2-5/+7
Since we always include the raw syscall number when tracing, also including it in the name when it's unknown is redundant. Simplify the code by using a constant string.
2015-06-18sim: callback: fix sentinel testing when walking mapsMike Frysinger2-2/+7
The new helpers for walking the maps tested the wrong value for exiting the for loop. This caused crashes when looking up entries that were not in the map.
2015-06-17sim: syscall: add common sim_syscall helpersMike Frysinger4-1/+100
Many ports have the same sim syscall logic, so add some helpers to handle all the common details. The arches still have to deal with the unpacking and packing of the syscall arguments, but the rest of the sim<->callback glue is now shared.
2015-06-17sim: syscall: unify memory helpersMike Frysinger4-0/+86
Almost every port implements these two callbacks in the same way, so unify them in the common layer.
2015-06-17sim: callback: add human readable strings for debugging to mapsMike Frysinger3-18/+99
When tracing, we often want to display the human readable name for the various syscall/errno values. Rather than make each target duplicate the lookup, extend the existing maps to include the string directly, and add helper functions to look up the constants. While most targets are autogenerated (from libgloss), the bfin/cris targets have custom maps for the Linux ABI which need to be updated by hand.
2015-06-12sim: update configure.in->configure.ac docsMike Frysinger3-4/+9
A few places still refer to the configure.in file; update them.
2015-06-12sim: drop -DTRACE from configureMike Frysinger3-6/+11
No code uses this anymore and the symbol conflicts with the new TRACE helper. Punt it from configure.
2015-06-12sim: trace: add common macros for logging infoMike Frysinger2-0/+28
The Blackfin port had some TRACE_xxx macros for easily logging trace data. Use these as a base for common ones that have a simple form and match the existing sets of helper macros.
2015-06-12sim: trace: add WITH_TRACE_ANY_P helperMike Frysinger4-8/+19
We have STRACE_ANY_P and TRACE_ANY_P, so add WITH_TRACE_ANY_P to fill out the API. This lets us wrap the internal configure symbol.
2015-06-12sim: cgen: namespace custom trace functionsMike Frysinger5-34/+77
The cgen code declares some macros/funcs using the trace_xxx prefix, but the code isn't generic and only works with cgen targets. This is blocking the creation of new common trace functions. Let's blindly add cgen_xxx prefixes to all these symbols. Some already use this convention to avoid conflicts, so it makes sense to align them. In the future we might want to move some to the common trace core, but one thing at a time.
2015-06-11sim: trace: centralize the system tracingMike Frysinger4-17/+14
First we convert the ETRACE_P to STRACE_EVENTS_P. This means we move from using the sim_events.trace storage to the common sim_state_base.trace_data array. With that deleted, the common trace init code can be simplified so the sim state works the same as the sim cpu.
2015-06-11sim: trace: add STRACE_xxx_P macrosMike Frysinger2-0/+21
These are the parallel to the TRACE_xxx_P macros and fill out the full set to match the existing debug one.
2015-06-11sim: trace: use existing defines for the useful maskMike Frysinger2-4/+5
No point in duplicating the shift logic when we have macros already to keep that all unified.
2015-06-11sim: trace: create a common WITH_TRACE_P macroMike Frysinger2-19/+28
This way we can use the IDX macros everywhere and not worry about the encoding of the WITH_TRACE define in multiple places.

2015-04-21sim: mcore: switch to common syscall handlingMike Frysinger3-0/+27
Now that libgloss has a header tracking the syscalls for this arch, we can update the database to include it for the symbolic constants/maps. Then we can switch the mcore syscall callbacks over to the common ones.
2015-04-21sim: gennltvals.sh: handle split out newlib source treeMike Frysinger5-17/+32
Since newlib no longer shares the same repo as binutils/gdb, we have to go searching further afield to locate the sources. We still look at the top level for newlib, but if that is not found, we also try up one dir outside of this source tree. It sucks, but better than the status quo (no workie).
2015-04-18sim: unify SIM_CPU definitionMike Frysinger2-0/+6
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 Frysinger3-5/+8
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 Frysinger5-6/+14
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.
2015-04-15sim: unify sim-cpu usageMike Frysinger3-5/+15
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 Frysinger3-3/+8
This should be SIM, not GDB.
2015-04-13sim: options: add --version supportMike Frysinger2-0/+18
The old run frontend had a --version option, but the new common sim-options file does not. Restore support for that so we can get version info out of `run` when using the new frontend.
2015-04-13sim: switch to gdb version scriptMike Frysinger3-40/+8
Since the local create-version.sh already points directly into the gdb source tree, we might as well use the gdb script directly too.
2015-04-06sim: move sim-engine.o/sim-hrw.o to the common listMike Frysinger2-0/+6
This makes these two objects available to all sims by default.
