sim: use -Werror when probing for supported warning flags When building with clang, we get: error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option] This is because clang only warns by default when encountering an unknown warning option, and the probe for supported warning flags is done without -Werror. All flags are therefore accepted by configure, but then it breaks when actually compiling a source file with -Werror. This is equivalent to this commit in gdb: 3e019bdc20eb81b91ab5bc774386201b874c0bac gdb: Use -Werror when checking for (un)supported warning flags We then see some other compilation errors when building with clang and -Werror, they can be dealt with later.

sim: switch to AC_CHECK_FUNCS_ONCE & merge a little This avoids duplicate tests for functions between common m4, arches, and any other sources that would trigger func tests. Also manually delete known duplicate function tests between the m4, bfin, and v850 ports.

* configure: Regenerate.
sim: cgen: move cgen_cpu_max_extra_bytes logic into the common code Every arch handles this the same way, so move it to the common code. This will also make unifying the sim_cpu structure easier.
2016-08-12 22:12:41 +08:00
2021-04-12 Mike Frysinger <vapier@gentoo.org>
* msp430-sim.c (sim_open): Delete 3rd arg to sim_cpu_alloc_all.
sim: unify toolchain settings The toplevel, common, and igen dirs all have their own code for setting up toolchain settings. Unify all of that in a new macro.

2021-04-02 Mike Frysinger <vapier@gentoo.org>
* aclocal.m4, configure: Regenerate.
sim: require AC_PROG_CPP explicitly 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.
2021-02-22 08:24:10 +08:00
2021-02-28 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: delete unused SIM_EXTRA_LIBDEPS This was last used 15 years ago, so clearly not important enough to keep around. Punt it.
2021-02-22 08:08:14 +08:00
2021-02-28 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_EXTRA_LIBDEPS): Delete.
sim: delete redundant SIM_EXTRA_ALL 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.
2021-02-22 08:02:47 +08:00
2021-02-27 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_EXTRA_ALL): Delete.
sim: common: split up acinclude.m4 into individual m4 files 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.
2021-02-07 11:51:30 +08:00
2021-02-21 Mike Frysinger <vapier@gentoo.org>
* configure.ac (AC_CONFIG_MACRO_DIRS): Replace common with m4.
* aclocal.m4, configure: Regenerate.
sim: switch to AC_CONFIG_MACRO_DIRS 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.
2021-02-07 08:46:16 +08:00
2021-02-13 Mike Frysinger <vapier@gentoo.org>
* configure.ac: Replace sinclude with AC_CONFIG_MACRO_DIRS.
* aclocal.m4, configure: Regenerate.
sim: drop use of bfd/configure.host 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.

2021-02-06 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: clean up C11 header includes 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.

* config.in, configure: Regenerate.
sim: enable -Werror by default for some arches 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.

2021-01-09 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: require a C11 compiler With GDB requiring a C++11 compiler now, this hopefully shouldn't be a big deal. It's been 10 years since C11 came out, so should be plenty of time to upgrade. This will allow us to start cleaning up random header logic and many of our non-standard custom types.

MSP430: sim: Increase main memory region size The area between 0xFF00 and 0xFFC0 is unallocated in the simulator memory map, so extend the main memory region up to 0xFFC0 to allow the simulator to make use of the extra 192 bytes of space. sim/msp430/ChangeLog: * msp430-sim.c (sim_open): Increase the size of the main memory region to 0xFAC0.

* msp430-sim.c (sim_open): Increase the size of the main memory region
to 0xFAC0.
MSP430: sim: Fix incorrect simulation of unsigned widening multiply Operand sizes used for simulation of MSP430 hardware multiply operations are not aligned with the sizes used on the target, resulting in the simulator storing signed operands with too much precision. Additionally, simulation of unsigned multiplication is missing explicit casts to prevent any implicit sign extension. gcc.c-torture/execute/pr91450-1.c uses unsigned widening multiplication of 32-bit operands -4 and 2, to produce a 64-bit result: 0xffff fffc * 0x2 = 0x1 ffff fff8 If -4 is stored in 64-bit precision, then the multiplication is essentially signed and the result is -8 in 64-bit precision (0xffff ffff ffff fffc), which is not correct. sim/msp430/ChangeLog: * msp430-sim.c (put_op): For unsigned multiplication, explicitly cast operands to the unsigned type before multiplying. * msp430-sim.h (struct msp430_cpu_state): Fix types used to store hwmult operands. sim/testsuite/sim/msp430/ChangeLog: * mpyull_hwmult.s: New test.

operands.
MSP430: Fix simulator execution of RRUX instruction The MSP430X RRUX instruction (unsigned right shift) is synthesized as the RRC (rotate right through carry) instruction, but with the ZC (zero carry) bit of the opcode extention word set. Ensure the carry flag is ignored when the ZC bit is set. sim/msp430/ChangeLog: 2020-01-22 Jozef Lawrynowicz <jozef.l@mittosystems.com> * msp430-sim.c (msp430_step_once): Ignore the carry flag when executing an RRC instruction, if the ZC bit of the extension word is set. sim/testsuite/sim/msp430/ChangeLog: 2020-01-22 Jozef Lawrynowicz <jozef.l@mittosystems.com> * rrux.s: New test.

* sim/msp430/msp430-sim.c (maybe_perform_syscall): Fix passing of
arguments for variadic syscall "open".
sim: unify symbol table handling The common sim tracing code already handles loading and tracking of symbols from the target program so that it can show symbol info in trace/disassembly calls. Once we touch up the trace code and add a few API callbacks, ports don't need to do loading and searching of symbol tables themselves anymore.

2016-08-15 Mike Frysinger <vapier@gentoo.org>
* msp430-sim.c: Delete bfd.h include.
(lookup_symbol, msp430_sim_close): Delete.
(sim_open): Change lookup_symbol to trace_sym_value.
* sim-main.h (struct sim_state): Delete symbol_table and
number_of_symbols.
(STATE_SYMBOL_TABLE, STATE_NUM_SYMBOLS, msp430_sim_close,
SIM_CLOSE_HOOK): Delete.
sim: move many common settings from CPPFLAGS to config.h 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.

* config.in, configure: Regenerate.
sim: drop targ-vals.def->nltvals.def indirection 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.

* configure: Regenerate.
sim: allow the assert configure option everywhere 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.

* configure: Regenerate.
sim: drop unused SIM_AC_OPTION_PACKAGES 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.

sim: allow the inline configure option everywhere 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.

* configure.ac (SIM_AC_OPTION_INLINE): Delete call.
* configure: Regenerate.
sim: drop --enable-sim-cflags option 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.
2016-01-09 17:00:53 +08:00
2016-01-10 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: drop --enable-sim-{regparm,stdcall} options 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.
2016-01-09 18:13:37 +08:00
2016-01-10 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: drop common/cconfig.h in favor of a single config.h 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.

* msp430-sim.c (sim_open): Mark argv const.
(sim_create_inferior): Mark argv and env const.
sim: msp430: drop duplicate sim_load_file call There's no need, or desire, to call sim_load_file from sim_open. The higher levels (gdb/run) take care of calling sim_load for us already.
2016-01-04 13:25:46 +08:00

(sim_open): Delete prog_bfd variable. Delete call to sim_load_file.
Delete prog_bfd check.
sim: msp430: switch to common disassembler tracing The output format is a bit different, but the new form matches all the other trace lines. Otherwise, it should be functionally equivalent.
2015-12-31 12:19:01 +08:00
2016-01-05 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Delete trace.o.

(msp430_dis_read): Delete function.
(msp430_step_once): Replace disassembly logic with a call
to TRACE_DISASM.
* trace.c, trace.h: Delete files.
sim: punt x86-specific bswap logic 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.

sim: drop host endian configure option 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.

* config.in, configure: Regenerate.
sim: convert to bfd_endian 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.

sim: aarch64/msp430: fix disassembler usage The disasm framework reserves the private_data field for the disassemblers themselves, not for people who use the disassembler. Instead, there is an application_data field for callers such as the sim. Switch to it to avoid random corruption/crashes when the disassemblers use private_data.
2015-12-27 14:41:27 +08:00
2015-12-27 Mike Frysinger <vapier@gentoo.org>
* msp430-sim.c (sim_dis_read): Change private_data to application_data.
(msp430_step_once): Likewise.
sim: unify sim-hload 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.
2015-04-11 07:40:34 +08:00
2015-12-27 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Delete sim-hload.o.
sim: punt WITH_DEVICES & tconfig.h support 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.

sim: sim-stop/sim-reason/sim-reg: move to common obj list 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.

* Makefile.in (SIM_OBJS): Delete sim-reason.o, sim-reg.o, and
sim-stop.o.
sim: sim-close: unify sim_close logic 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: trace: add a basic cpu register class 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.

(trace_reg_get): Likewise.
sim: use AS_HELP_STRING everywhere This helps standardize the configure --help output.
2015-06-24 01:58:48 +08:00
2015-06-23 Mike Frysinger <vapier@gentoo.org>
* configure: Regenerate.
sim: syscall: add common sim_syscall helpers 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.
2015-06-15 21:37:38 +08:00
2015-06-17 Mike Frysinger <vapier@gentoo.org>
* msp430-sim.c (maybe_perform_syscall): Replace call to cb_syscall
with sim_syscall.
sim: syscall: unify memory helpers Almost every port implements these two callbacks in the same way, so unify them in the common layer.
2015-06-15 23:24:21 +08:00
2015-06-17 Mike Frysinger <vapier@gentoo.org>
* msp430-sim.c: Include sim-syscall.h.
(syscall_read_mem, syscall_write_mem): Delete.
(maybe_perform_syscall): Change syscall_read_mem/syscall_write_mem
to sim_syscall_read_mem/sim_syscall_write_mem.
sim: drop -DTRACE from configure No code uses this anymore and the symbol conflicts with the new TRACE helper. Punt it from configure.
2015-06-12 22:32:54 +08:00

* configure: Regenerate.
sim: msp430: use new common trace print helpers Replace the "if (TRACE_xxx_P) trace_generic" form with "TRACE_xxx". The output is the same, but the code is nicer to read.
2015-06-12 22:07:55 +08:00
2015-06-12 Mike Frysinger <vapier@gentoo.org>
* msp430-sim.c (trace_reg_put): Replace TRACE_VPU_P/trace_generic
with TRACE_VPU.
(trace_reg_get): Likewise.
(get_op): Replace TRACE_MEMORY_P/trace_generic with TRACE_MEMORY.
(put_op): Likewise.
(msp430_dis_read): Replace TRACE_ALU_P/trace_generic with TRACE_ALU.
(do_flags): Likewise.
(maybe_perform_syscall): Replace TRACE_SYSCALL_P/trace_generic with
TRACE_SYSCALL.
(msp430_step_once): Replace TRACE_ALU_P/trace_generic with TRACE_ALU.
Replace TRACE_BRANCH_P/trace_generic with TRACE_BRANCH.
sim: msp430: delete unused trace macros These macros were copied from the Blackfin port but never used, so delete them as part of the trace unification work.
2015-06-12 00:08:11 +08:00
2015-06-11 Mike Frysinger <vapier@gentoo.org>
* sim-main.h (MAYBE_TRACE, TRACE_INSN, TRACE_DECODE, TRACE_EXTRACT,
TRACE_SYSCALL, TRACE_CORE, TRACE_EVENTS, TRACE_BRANCH,
trace_register, TRACE_REGISTER, TRACE_REG): Delete.
sim: unify SIM_CPU definition 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.
2015-04-18 16:19:56 +08:00
2015-04-18 Mike Frysinger <vapier@gentoo.org>
* sim-main.h (SIM_CPU): Delete.
sim: unify sim_cia definition 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.
2015-04-18 16:08:56 +08:00
2015-04-18 Mike Frysinger <vapier@gentoo.org>
* sim-main.h (sim_cia): Delete.
sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET} 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.
2015-04-16 14:11:12 +08:00
2015-04-17 Mike Frysinger <vapier@gentoo.org>
* sim-main.h (CIA_GET, CIA_SET): Delete.
sim: unify sim-cpu usage 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.
2015-04-15 14:13:23 +08:00
2015-04-15 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Delete sim-cpu.o.
* sim-main.h (STATE_CPU): Delete.
sim: fix the PKGVERSION define This should be SIM, not GDB.
2015-04-13 14:38:57 +08:00

2015-04-07 11:40:00 +08:00
2015-04-06 Mike Frysinger <vapier@gentoo.org>

2015-04-01 14:34:00 +08:00
2015-04-01 Mike Frysinger <vapier@gentoo.org>
* Makefile.in (SIM_OBJS): Delete $(SIM_EXTRA_OBJS).
sim: update zlib handling With zlib being mandatory, and the updated m4 configs, we need to regen and use the new settings w/bfd to avoid linkage errors.
2015-04-01 11:32:49 +08:00
2015-03-31 Mike Frysinger <vapier@gentoo.org>
* config.in, configure: Regenerate.
sim: bfin/msp430: drop run-sim.h include This header is used only with run.o, and both of these use nrun.o.
2015-03-23 12:08:25 +08:00
2015-03-23 Mike Frysinger <vapier@gentoo.org>
* sim-main.h: Delete run-sim.h include.
sim: rename tconfig.in to tconfig.h 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.

* aclocal.m4, configure: Regenerate.
* configure.ac: Call the common inline & warning macros.
* msp430-sim.c: Include unistd.h & trace.h.
* trace.c: Include trace.h.
(load_file_and_line): Move FILE* decl to top of scope.
* trace.h (msp430_get_current_source_location): Adjust prototype to
match the function definition.
sim: make nrun the default run program 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.
