2021-06-15sim: switch modules.c & version.c to stamp filesMike Frysinger1-0/+7
This fixes remaking of these files and avoids unnecessary rebuilds. Also add both to `make clean` to match other stamp files.
2021-06-14sim: enable silent rules in common buildsMike Frysinger1-0/+4
We only do the common code as automake simplifies the logic.
2021-06-14gnulib: define the path to gnulib's parent dirMike Frysinger1-0/+5
The current setting assumes that gnulib is only used by dirs immediately under the source root. Trying to build it two or more levels deep fails. Switch GNULIB_BUILDDIR to a relative GNULIB_PARENT_DIR so that it can be used to construct both the build & source paths.
2021-06-12sim: start unifying portability shimsMike Frysinger1-0/+6
There are some functions that gnulib does not yet provide fallbacks for, so start a common file of our own for holding existing stubs.
2021-06-12sim: unify sim-load.o buildingMike Frysinger1-0/+9
Since this file does not rely on any port-specific settings, move it up to building as part of the common step so we only do it once in a multibuild.
2021-06-12sim: assume sys/select.h always existsMike Frysinger1-0/+4
Now that gnulib provides this, assume it exists.
2021-06-12sim: overhaul alignment settings managementMike Frysinger1-0/+8
Currently, the sim-config module will abort if alignment settings haven't been specified by the port's configure.ac. This is a bit weird when we've allowed SIM_AC_OPTION_ALIGNMENT to seem like it's optional to use. Thus everyone invokes it. There are 4 alignment settings, but really only 2 matters: strict and nonstrict. The "mixed" setting is just the default ("unset"), and "forced" isn't used directly by anyone (it's available as a runtime option for some ports). 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, then the build won't work (see above as if SIM_AC_OPTION_ALIGNMENT wasn't called). If default settings are provided, then that is used, but we allow the user to override at runtime. Otherwise, the "wire" settings are used and user runtime options to change are ignored. Most ports specify a default, or set the "wire" to nonstrict. A few set "wire" to strict, but it's not clear that's necessary as it doesn't make the code behavior, by default, any different. It might make things a little faster, but we should provide the user the choice of the compromises to make: force a specific mode at compile time for faster runtime, or allow the choice at runtime. More likely it seems like an oversight when these ports were initially created, and/or copied & pasted from existing ports. With all that backstory, let's get to what this commit does. First kill off the idea of a compile-time default alignment and set it to nonstrict in the common code. For any ports that want strict alignment by default, that code is moved to sim_open while initializing the sim. That means WITH_DEFAULT_ALIGNMENT can be completely removed. Moving the default alignment to the runtime also allows removal of setting the "wire" settings at configure time. Which allows removing of all arguments to SIM_AC_OPTION_ALIGNMENT and moving that call to common code. The macro logic can be reworked to not pass WITH_ALIGNMENT as -D CPPFLAG and instead move it to config.h. All of these taken together mean we can hoist the macro up to the top level and share it among all sims so behavior is consistent among all the ports.
2021-06-12sim: unify platform function & header testsMike Frysinger1-0/+4
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.
2021-06-09sim: cleanup obsolete NULL fallbackMike Frysinger1-0/+4
We require C11 which defines NULL, so drop the inconsistent set of fallback defines in the codebase.
2021-06-09sim: nrun: tweak init of callback endianMike Frysinger1-0/+5
Allow ports to initialize the callback endian if they want. This will allow delegation of the logic out of common code in the future. Also switch from the CURRENT_TARGET_BYTE_ORDER macro to the underlying current_target_byte_order storage since the latter has been setup by the sim-config module based on the same macros. This will allow the nrun module to be moved to common building for sharing.
2021-06-09sim: cgen: inline cgen_init logicMike Frysinger1-0/+9
This function has done only one thing: post-process command line settings to see if profiling or tracing has been enabled, and if so, set the run_fast_p flag in the simulator state. That flag is only used in one place: to select the fast or slow cgen engine. By inlining the run_fast_p logic to the one place it's used, we can delete a good amount of logic specific to cgen ports: both the call to cgen_init and the conditional simulator state. This in turn allows us to have a single simulator state struct across all ports so we can share objects more between them, and makes the sim_open calls look more consistent.
2021-06-08sim: igen: harmonize tool variablesMike Frysinger1-0/+5
Separate the name of the igen program from the options used to run it. This allows us to avoid duplicating ../igen/igen in Makefiles and reuse the existing setting in the common Makefile. This also allows us to easily harmonize the use of EXEEXT between igen/local.mk and the common makefiles when cross-compiling for e.g. Windows.
2021-06-05sim: common: start dedicated local.mkMike Frysinger1-0/+8
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.
2021-05-29sim: pull in extra gnulib libs tooMike Frysinger1-0/+4
Some modules might require extra linking depending on the platform (e.g. Windows might need -lws2_32), so include the existing extra gnulib libs setting.
2021-05-29sim: leverage gnulibMike Frysinger1-0/+9
We use getline, so leverage gnulib to provide fallback implementation.
2021-05-17sim: fully merge sim_state_base into sim_stateMike Frysinger1-0/+37
Now that all ports have migrated to the new framework, drop support for the old sim_state_base layout.
2021-05-17sim: cgen: invert sim_state storage for cgen portsMike Frysinger1-0/+8
2021-05-17sim: invert sim_state storageMike Frysinger1-0/+10
Currently all ports have to declare sim_state themselves in their sim-main.h and then embed the common sim_state_base & sim_cpu in it. This dynamic makes it impossible to share common object code among multiple ports because the core data structure is always different. Let's invert this relationship: common code declares sim_state, and if the port actually needs state on a per-instance basis, it can use the new arch_data field for it. Most ports don't actually use it, so they don't need to declare anything at all. This is the first in a series of changes: it adds a define to select between the old & new layouts, then converts all the ports that don't need custom state over to the new layout.
2021-05-16sim: switch config.h usage to defs.hMike Frysinger1-0/+21
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.
2021-05-15sim: switch to libiberty environ.hMike Frysinger1-0/+6
Drop our compat code and assume environ exists to simplify.
2021-05-14sim: callback: convert FS interfaces to 64-bitMike Frysinger1-0/+8
Rather than rely on off_t being the right size between the host & target, have the interface always be 64-bit. We can figure out if we need to truncate when actually outputting it to the right target.
2021-05-14sim: callback: convert time interface to 64-bitMike Frysinger1-0/+9
PR sim/27705 Rather than rely on time_t being the right size between the host & target, have the interface always be 64-bit. We can figure out if we need to truncate when actually outputting it to the right target.
2021-05-14sim: callback: inline PTR defineMike Frysinger1-0/+5
We require C11 now, so no need for these pre-ANSI C hacks. PTR is simply void*, so use that directly.
2021-05-14sim: create header namespaceMike Frysinger1-0/+12
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.
2021-05-08sim: touch modules targetMike Frysinger1-0/+4
If there are no updates to the file, touch the result so we don't keep trying to regenerate it.
2021-05-08sim: cgen: tweak trace formatMike Frysinger1-0/+4
Fixes build warnings when the address size isn't an integer.
2021-05-08sim: cgen: namespace mode_names a bitMike Frysinger1-0/+8
These are exported in the library linkage, so add a cgen_ prefix.
2021-05-08sim: cgen: tweak cgen_rtx_error to fix warningsMike Frysinger1-0/+5
The function was missing a prototype, and passing a constant string as the format string instead of going through a %s format.
2021-05-08sim: cgen: tweak initializers to avoid warningsMike Frysinger1-0/+4
Use {} instead of {0} to avoid warnings: common/cgen-utils.c:59:1: warning: missing braces around initializer [-Wmissing-braces] 59 | { | ^ 60 | { 61 | VIRTUAL_INSN_X_INVALID, "--invalid--", NULL, 0, { V, { 0 } } | {{}} Generated code should be the same.
2021-05-08sim: add html & pdf stubsMike Frysinger1-0/+5
We stub out the info targets already since we don't provide any.
2021-05-08sim: use htab_eq_stringTom Tromey1-0/+5
This changes the sim to use htab_eq_string from libiberty. sim/common/ChangeLog 2021-05-08 Tom Tromey <tom@tromey.com> * sim-options.c (compare_strings): Remove. (dup_arg_p): Use htab_eq_string.
2021-05-04sim: hw: localize init callbackMike Frysinger1-0/+8
Now that we don't need to hardcode the module init list in a single place, move the hw init logic out to the sim-hw file.
2021-05-04Add config.h to generated_files for simTom Tromey1-0/+4
I noticed that config.h isn't in 'generated_files' in the sim subdirectories. This causes it to sometimes be rebuilt too late. 2021-05-04 Tom Tromey <tromey@adacore.com> * Make-common.in (generated_files): Add config.h.
2021-05-04sim: clean up bfd_vma printingMike Frysinger1-0/+7
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.
2021-05-03sim: add ATTRIBUTE_PRINTF / ATTRIBUTE_NULL_PRINTF where necessarySimon Marchi1-0/+13
I finally got the all-targets sim building with Clang, these are all the instances where an ATTRIBUTE_PRINTF or ATTRIBUTE_NULL_PRINTF attribute needed to be added to avoid errors like: /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-profile.c:464:19: error: format string is not a string literal [-Werror,-Wformat-nonliteral] vfprintf (fp, fmt, ap); ^~~ There are more fixes needed to get everything building, but adding these attributes is trivial enough, so I send them all in a single patch. Adding the format attributes introduces some format string errors when building with GCC (because now format strings are checked), so corresponding changes are needed to avoid breaking the build. Other than simple format string specified changes, there is this one: /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c: In function 'hw_event_queue_schedule': /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c:95:15: error: too many arguments for format [-Werror=format-extra-args] 95 | NULL, dummy); | ^~~~~ We can fix it and avoid using a dummy variable by simply calling hw_event_queue_schedule_tracef instead of hw_event_queue_schedule_vtracef. sim/arm/ChangeLog: * armdefs.h (ARMul_ConsolePrint): Use format attribute. * wrapper.c (op_printf): Likewise. sim/bfin/ChangeLog: * interp.c (sim_open): Adjust format string specifier. sim/common/ChangeLog: * hw-events.h (hw_event_queue_schedule_tracef): Use format attribute. (hw_event_queue_schedule_vtracef): Likewise. * hw-tree.h (hw_tree_vparse): Likewise. * sim-profile.c (profile_vprintf): Likewise. * sim-trace.c (dis_printf): Likewise. * sim-trace.h (trace_printf): Likewise. (trace_vprintf): Likewise. * sim-utils.h (sim_do_commandf): Likewise. * hw-events.c (hw_event_queue_schedule): Use hw_event_queue_schedule_tracef. sim/rx/ChangeLog: * trace.c (op_printf): Likewise. sim/v850/ChangeLog: * interp.c (sim_open): Adjust format string specifier.

2021-05-02sim: add default cases to two switches in sim-options.cSimon Marchi1-0/+5
This is the next compilation error I hit when I build all targets with Clang: /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-options.c:234:12: error: no case matching constant switch condition '0' [-Werror] switch (WITH_ENVIRONMENT) ^~~~~~~~~~~~~~~~ ./config.h:215:26: note: expanded from macro 'WITH_ENVIRONMENT' #define WITH_ENVIRONMENT ALL_ENVIRONMENT ^~~~~~~~~~~~~~~ /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-options.c:276:15: error: no case matching constant switch condition '0' [-Werror] switch (WITH_ALIGNMENT) ^~~~~~~~~~~~~~ /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-config.h:220:24: note: expanded from macro 'WITH_ALIGNMENT' #define WITH_ALIGNMENT 0 ^ This is a little bit special because these are switches on compile-time value. But regardless, the idea is that we logically can't reach the switches if WITH_ENVIRONMENT == 0 or WITH_ALIGNMENT == 0, so the code is correct. In addition to getting rid of the compiler warning, adding default cases to these switches ensure that if we do get in an unexpected situation, it is caught. In GDB, I'd use gdb_assert_not_reached, I don't know if there is something similar in sim so I went with abort. sim/common/ChangeLog: * sim-options.c (standard_option_handler): Add default cases to switches. Change-Id: Ie237d67a201caa6b72de0d17cc815193417156b6
2021-05-02sim: replace custom attributes with ansidecl.hMike Frysinger1-0/+23
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: options: fix --help outputMike Frysinger1-0/+4
The hash table rewrite broke --help output due to subtle behavior: calling dup_arg_p(NULL) will create & clear the table, not just create it. The --help output relies on this to clear the table before it shows things.
2021-05-01sim: dv-sockser: localize init callbackMike Frysinger1-0/+8
Now that we don't need to hardcode the module init list in a single place, move the dv-sockser logic to the place to the one file.
2021-05-01sim: add framework for declaring init callbacks locallyMike Frysinger1-0/+14
To facilitate decentralized module initialization/registration with an eye towards multi-target support, add a framework to detect init calls declared in the source and automatically call them. This is akin to gdb's _initialize_xxx framework for letting modules autodiscover.
2021-05-01sim: nrun: add local strsignal prototypeMike Frysinger1-0/+4
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.
2021-05-01sim: callback: inline wrap helperMike Frysinger1-0/+7
This is annoying as it requires inlining boiler plate, but we don't have much choice: the wrap helper assumes the return value is always an int, but that's already not the case with some of the callbacks which use long. GCC has extensions to define macros-as-functions, but we can't assume GCC.
2021-04-26sim: nltvals: unify common syscall tablesMike Frysinger1-0/+8
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.
2021-04-25Use htab_t in sim-options.cTom Tromey1-0/+7
This changes sim-options.c to use the libiberty hash table, rather than its own custom hash table. sim/common/ChangeLog 2021-04-25 Tom Tromey <tom@tromey.com> * sim-options.c (compare_strings): New function. (ARG_HASH_SIZE, ARG_HASH): Remove. (dup_arg_p): Use htab_t. (sim_parse_args): Remove assert.
2021-04-24sim: dv-cfi: fix printf formatMike Frysinger1-0/+4
Use the existing PRI constants to select the right format rather than assume signed_cell is always %u. Fixes building for riscv64.
2021-04-24sim: options: increase max option countMike Frysinger1-0/+5
As we turn on more modules by default for all ports, the number of options has been increasing. The sim-options module has a limit on the number of options it can support, and if it's exceeded, it likes to go into an infinite loop. Increase the ceiling and add an assert so we abort right away instead of hanging. This will be needed to turn on hw support for v850 as it will then exceed the current limit.
2021-04-22Do not check for sys/time.h or sys/times.hTom Tromey1-0/+4
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 Tromey1-0/+4
GDB has required GNU make for quite some time, and this patch applies this approach to the sim as well. Requiring GNU make means that automatic dependency tracking can be simple and reliable, and it also makes other refactorings simpler. sim/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * m4/sim_ac_common.m4 (SIM_AC_COMMON): Don't check for make. sim/aarch64/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/arm/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/avr/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/bfin/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Make-common.in: Require GNU make. sim/cr16/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/cris/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/d10v/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/erc32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/example-synacor/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/frv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/ft32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/h8300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/iq2000/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/lm32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/m32c/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/m32r/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/m68hc11/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/mcore/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/microblaze/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/mips/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/mn10300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/moxie/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/msp430/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/or1k/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/pru/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/riscv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/rl78/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/rx/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/sh/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild. sim/v850/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure: Rebuild.
2021-04-22Introduce stamp file for hw-config.hTom Tromey1-0/+6
This adds a stamp file for hw-config.h, to avoid unnecessary rebuilds. It also arranges to remove hw-config.h in "mostlyclean", because the file is created by "make". sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Make-common.in (stamp-hw): New target. (hw-config.h): Depend on stamp-hw. (mostlyclean): Remove stamp-hw and hw-config.h.
2021-04-22Make mostlyclean an alias for cleanTom Tromey1-0/+5
I found out by accident that "mostlyclean" in a sim subdir removes all the configure artifacts. The usual rule is: * If the maintainer built it, maintainer-clean should remove it; * If configure built it, distclean should remove it; * If make built it, "clean" should remove it; * If there is a handy subset of "clean" that is "easy" to rebuild, "mostlyclean" should remove it; otherwise mostlyclean should be an alias for clean This patch makes mostlyclean an alias for clean. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * Make-common.in (mostlyclean): Now an alias for clean, not distclean.
