2021-06-19sim: unify toolchain probing logicMike Frysinger2-1360/+26
Move these options up to the common dir so we only test & export them once across all ports.
2021-06-19sim: unify bfd library dependency testing logicMike Frysinger3-7691/+6
Move these options up to the common dir so we only test & export them once across all ports.
2021-06-19sim: unify various library testing logicMike Frysinger2-141/+6
Move these options up to the common dir so we only test & export them once across all ports.
2021-06-18sim: unify -Werror build settingsMike Frysinger3-112/+6
Move these options up to the common dir so we only test & export them once across all ports. It also enables -Werror usage on the common files we've been pulling out of arch subdirs.
2021-06-18sim: move -Werror disabling to MakefileMike Frysinger2-5/+8
For the ports that still don't build with -Werror, rather than disable the flag at configure time, do it at make time. This will allow us to unify these tests in the common sim configure script.
2021-06-17sim: overhaul & unify endian settings managementMike Frysinger2-6/+6
The m4 macro has 2 args: the "wire" settings (which represents the hardwired port behavior), and the default settings (which are used if nothing else is specified). If none are specified, the arch is expected to support both, and the value will be probed based on the user runtime options or the input program. Only two arches today set the default value (bpf & mips). We can probably let this go as it only shows up in one scenario: the sim is invoked, but with no inputs, and no user endian selection. This means bpf will not behave like the other arches: an error is shown and forces the user to make a choice. If an input program is used though, we'll still switch the default to that. This allows us to remove the WITH_DEFAULT_TARGET_BYTE_ORDER setting. For the ports that set a "wire" endian, move it to the runtime init of the respective sim_open calls. This allows us to change the WITH_TARGET_BYTE_ORDER to purely a user-selected configure setting if they want to force a specific endianness. With all the endian logic moved to runtime selection, we can move the configure call up to the common dir so we only process it once across all ports. The ppc arch was picking the wire endian based on the target used, but since we weren't doing that for other biendian arches, we can let this go too. We'll rely on the input selecting the endian, or make the user decide.
2021-06-16sim: drop obsolete AC_EXEEXT callMike Frysinger2-2/+4
The current autoconf 2.69 defines this to nothing because the logic in AC_PROG_CC takes care of it all the time now. Delete the call.
2021-06-16sim: drop arch-specific config.hMike Frysinger3-280/+47
All of the settings in here are handled by the common top-level config.h, so drop the individual arch-config.h files entirely. This will also help guarantee that we don't add any new arch specific defines that would affect common code which will help with the effort of unifying them.
2021-06-15sim: move dv-sockser define to CPPFLAGSMike Frysinger3-8/+5
This is the only define left in m4/ that is not in the common config.h, so move it to sim_hw_cflags so we can drop the arch-specific config.h.
2021-06-12sim: assume sys/select.h always existsMike Frysinger2-2/+4
Now that gnulib provides this, assume it exists.
2021-06-12sim: unify bug & package settingsMike Frysinger3-87/+2
Move these options up to the common dir so we only test & export them once across all ports. The AC_INIT macro does a lot of the heavy lifting already which allows further simplification.
2021-06-12sim: unify debug/stdio/trace/profile build settingsMike Frysinger2-150/+2
Move these options up to the common dir so we only test & export them once across all ports. The ppc code needs a little extra care with its trace settings as it's not exactly the same API as the common code. The other knobs are the same though.
2021-06-12sim: unify environment build settingsMike Frysinger3-32/+2
Move the --sim-enable-environment option up to the common dir so we only test & export it once across all ports.
2021-06-12sim: unify assert build settingsMike Frysinger4-28/+6
Move the --sim-enable-assert option up to the common dir so we only test & export it once across all ports.
2021-06-12sim: unify platform function & header testsMike Frysinger4-592/+7
Move the various platform tests up a level to avoid duplication across the ports. When building multiple versions, this speeds things up a bit. For now we move the obvious stuff up a level, but we don't turn own the config.h entirely just yet -- we still have some tests related to libraries that need consideration.
2021-06-02sim m32c: Include defs.h in m32c.opc and r8c.opc.John Baldwin3-0/+9
gnulib can override stdio.h and/or stdlib.h in which case the gnulib headers require config.h to be included first. gdb/sim/m32c/ChangeLog: * m32c.opc: Include defs.h. * r8c.opc: Likewise.
2021-05-29sim: m32c: rename open symbol to avoid collisionsMike Frysinger2-4/+10
If the header files define open(), make sure our local open var doesn't shadow it.
2021-05-16sim: switch config.h usage to defs.hMike Frysinger12-6/+32
The defs.h header will take care of including the various config.h headers. For now, it's just config.h, but we'll add more when we integrate gnulib in. This header should be used instead of config.h, and should be the first include in every .c file. We won't rely on the old behavior where we expected files to include the port's sim-main.h which then includes the common sim-basics.h which then includes config.h. We have a ton of code that includes things before sim-main.h, and it sometimes needs to be that way. Creating a dedicated header avoids the ordering mess and implicit inclusion that shows up otherwise.
2021-05-16sim: riscv: move __int128 check to configureMike Frysinger3-2/+19
2021-05-14sim: create header namespaceMike Frysinger3-3/+8
The gdb/callback.h & gdb/remote-sim.h headers have nothing to do with gdb and are really definitions for the libsim API under the sim/ tree. While gdb uses those headers as a client, it's not specific to it. So create a new sim/ namespace and move the headers there.
2021-05-07sim: m32c: clean up various warningsMike Frysinger5-21/+41
A random grab bag of minor fixes to enable -Werror for this port. Check the return values of read & write calls and issue warnings when they fail. Fixup funky pointer math as the compiler doesn't like ++ on void*. Handle short reads with fread().
2021-05-07sim: m32c: fix warnings about mixing code & declsMike Frysinger3-1/+31
Add scope braces to a bunch of the generated sections to avoid compiler warnings about mixing code & variable declarations.
2021-05-07sim: m32c: switch from custom fgets to getlineMike Frysinger5-105/+17
No need to implement this ourselves when POSIX has a nice API.
2021-05-05sim: m32c/rl78/rx: fix command parsingMike Frysinger2-25/+19
Use buildargv to avoid writing to const memory and freeing invalid pointers, and to avoid doing any string parsing ourselves.
2021-05-04sim: add support for build-time ar & ranlibMike Frysinger2-2/+14
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.
2021-05-04sim: clean up bfd_vma printingMike Frysinger2-2/+6
A lot of this code predates the bfd_vma format define, so we have a random mix of casts to known types so we can printf the value. Use the BFD_VMA_FMT that now exists to simplify and reliability output across different build configs.
2021-05-02sim: replace custom attributes with ansidecl.hMike Frysinger4-7/+14
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.
2021-05-01sim: nrun: add local strsignal prototypeMike Frysinger3-2/+12
While libiberty provides a definition for this for systems that lack the function (e.g. Windows), it doesn't provide a prototype. So add our own local copy in the one file that uses the func.
2021-04-26sim: nltvals: unify common syscall tablesMike Frysinger2-3/+4
Since libgloss provides a default syscall table for arches, use that to provide the default syscall table for ports. Only the exceptions need to be enumerated now with the common logic as the default.
2021-04-26sim: enable hardware support by defaultMike Frysinger4-6/+121
Force this on for all ports. We have a few common models that can be used, so make them generally available. If the port doesn't use any hardware (the default), then behavior is unchanged.
2021-04-22Do not check for sys/time.h or sys/times.hTom Tromey3-14/+6
This updates the sim so that it unconditionally uses sys/time.h. This is in agreement with existing code, and a recent change to BFD. I also think that sys/times.h is never needed by the sim, so this patch removes the check and the one spot that was conditionally including it. sim/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * m4/sim_ac_common.m4 (SIM_AC_COMMON): Don't check for sys/time.h or sys/times.h. sim/aarch64/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/arm/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/avr/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/bfin/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/bpf/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * sim-utils.c: Update includes. sim/cr16/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * simops.c: Update includes. * configure, config.in: Rebuild. sim/cris/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * rvdummy.c: Update includes. * dv-rv.c: Update includes. * configure, config.in: Rebuild. sim/d10v/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/erc32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/example-synacor/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/frv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/ft32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/h8300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/iq2000/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/lm32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m32c/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m32r/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m68hc11/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mcore/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/microblaze/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mips/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mn10300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/moxie/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/msp430/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/or1k/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/ppc/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * mon.c: Update includes. * emul_unix.c: Update includes.

2021-04-22Require GNU makeTom Tromey2-67/+6
GDB has required GNU make for quite some time, and this patch applies this approach to the sim as well.

2021-04-21sim: regen against sim/m4/Mike Frysinger2-7/+11
My scripts weren't updated to use new -I../m4 as the first arg.
2021-04-21sim: use -Werror when probing for supported warning flagsSimon Marchi2-1/+5
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.
2021-04-18sim: switch to AC_CHECK_HEADERS_ONCEMike Frysinger3-61/+70
This avoids duplicate tests for headers between common m4, arches, and any other sources that would trigger header tests.
2021-04-18sim: m32c: switch syscalls to common nltvalsMike Frysinger4-60/+19
Rather than hand duplicate the syscall table, switch to the common nltvals framework. We have to tweak the constant names, but we get everything else for free. I made sure the constants have the same values before & after too :).
2021-04-18sim: switch to AC_CHECK_FUNCS_ONCE & merge a littleMike Frysinger2-25/+52
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.
2021-04-08sim: set ASAN_OPTIONS=detect_leaks=0 when running igen and opc2cSimon Marchi2-2/+12
The igen/dgen and opc2c tools leak their heap-allocated memory (on purpose) at program exit, which makes AddressSanitizer fail the tool execution. This breaks the build, as it makes the tool return a non-zero exit code. Fix that by disabling leak detection through the setting of that environment variable. I also changed the opc2c rules for m32c to go through a temporary file. What happened is that the failing opc2c would produce an incomplete file (probably because ASan exits the process before stdout is flushed). This meant that further make attempts didn't try to re-create the file, as it already existed. A "clean" was therefore necessary. This can also happen in regular builds if the user interrupts the build (^C) in the middle of the opc2c execution and tries to resume it. Going to a temporary file avoids this issue. sim/m32c/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running opc2c. sim/mips/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen. sim/mn10300/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen. sim/ppc/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen. sim/v850/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen.

2021-04-07sim: m32c: opc2c: remove unused vlist variableSimon Marchi2-3/+4
When building with AddressSanitizer, sim/m32c fails with: ./opc2c -l r8c.out /home/simark/src/binutils-gdb/sim/m32c/r8c.opc > r8c.c sim_log: r8c.out ================================================================= ==3919390==ERROR: LeakSanitizer: detected memory leaks Direct leak of 4 byte(s) in 1 object(s) allocated from: #0 0x7ffff7677459 in __interceptor_malloc /build/gcc/src/gcc/libsanitizer/asan/asan_malloc_linux.cpp:145 #1 0x55555555b3df in main /home/simark/src/binutils-gdb/sim/m32c/opc2c.c:658 #2 0x7ffff741fb24 in __libc_start_main (/usr/lib/libc.so.6+0x27b24) Fix the leak in main by removing the vlist variable, which seems unused.
2021-04-02sim: unify toolchain settingsMike Frysinger3-153/+162
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: introduce {COMPILE,LINK}_FOR_BUILDMike Frysinger2-3/+8
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 Frysinger2-1/+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.
2021-02-28sim: set up build-time compiler settingsMike Frysinger1-9/+10
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 Frysinger1-3/+93
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 Frysinger2-140/+145
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.
2021-02-21sim: common: split up acinclude.m4 into individual m4 filesMike Frysinger4-14/+35
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 Frysinger4-1834/+35
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: erc32/m32c/rl78: add sim_memory_map stub for gdbMike Frysinger2-0/+10
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: common: switch AC_CONFIG_HEADERSMike Frysinger1-3/+2
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.
