Mike Frysinger	11e25f766e	sim: drop unused SIM_ADDR type [PR sim/7504] Now that sim APIs either use 64-bit addresses all the time, or more appropriate target-specific types, drop this now-unused 32-bit-only address type. Bug: https://sourceware.org/PR7504	3 years ago
Mike Frysinger	63fd5b5dda	sim: switch sim_{read,write} APIs to 64-bit all the time [PR sim/7504] We've been using SIM_ADDR which has always been 32-bit. This means the upper 32-bit address range in 64-bit sims is inaccessible. Use 64-bit addresses all the time since we want the APIs to be stable regardless of the active arch backend (which can be 32 or 64-bit). The length is also 64-bit because it's completely feasible to have a program that is larger than 4 GiB in size/image/runtime. Forcing the caller to manually chunk those accesses up into 4 GiB at a time doesn't seem useful to anyone. Bug: https://sourceware.org/PR7504	3 years ago
Mike Frysinger	d026e67ed4	sim: move register headers into sim/ namespace [PR sim/29869] These headers define the register numbers for each port to implement the sim_fetch_register & sim_store_register interfaces. While gdb uses these, the APIs are part of the sim, not gdb. Move the headers out of the gdb/ include namespace and into sim/ instead.	3 years ago
Mike Frysinger	195064c8da	sim: drop unused CORE_ADDR_TYPE This hasn't been used by gdb in decades, and doesn't make sense with a standalone sim program/library where the ABI is fixed. So punt it to simplify the code.	3 years ago
Mike Frysinger	ee1cffd388	sim: common: change sim_{fetch,store}_register helpers to use void* buffers When reading/writing arbitrary data to the system's memory, the unsigned char pointer type doesn't make that much sense. Switch it to void so we align a bit with standard C library read/write functions, and to avoid having to sprinkle casts everywhere.	3 years ago
Mike Frysinger	5bab16fdf1	sim: reg: constify store helper These functions only read from memory, so mark the pointer as const.	4 years ago

Alan Modra	a2c5833233	Update year range in copyright notice of binutils files The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out /po/.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.	4 years ago
Mike Frysinger	20a8e078cc	sim: reorder header includes We're including system headers after local headers in a bunch of places, but this leads to conflicts when our local headers happen to define symbols that show up in the system headers. Use the more standard order of: * config.h (via defs.h) * system headers * local library headers (e.g. bfd & libiberty) * sim specific headers	4 years ago
Mike Frysinger	8cfc9a1895	sim: callback: expose argv & environ Pass the existing strings data to the callbacks so that common libgloss syscalls can be implemented (which we'll do shortly).	4 years ago
Mike Frysinger	9335d9f823	sim: rename ChangeLog files to ChangeLog-2021 Now that ChangeLog entries are no longer used for sim patches, this commit renames all relevant sim ChangeLog to ChangeLog-2021, similar to what we would do in the context of the "Start of New Year" procedure. The purpose of this change is to avoid people merging ChangeLog entries by mistake when applying existing commits that they are currently working on. Also throw in a .gitignore entry to keep people from adding new ChangeLog files anywhere in the sim tree.	5 years ago
Mike Frysinger	a1d9117f94	sim: callback: add printf attributes This helps these funcs get printf format checking coverage. The sim-io.c hack as a result is a bit unfortunate, but the compiler throws warnings when printing with empty strings. In this one case, we actually want that due to the side-effect of the callback halting execution for us.	5 years ago
Mike Frysinger	bdedb2d21b	sim: callback: extend syscall interface to handle 7 args The Linux syscall interface, depending on architecture, handles up to 7 arguments. Extend the callback API to handle those.	5 years ago
Mike Frysinger	d394a6efed	sim: callback: add a kill interface This will make it easier to emulate the syscall. If the kill target is the sim itself, don't do anything. This forces the higher layers to make a decision as to how to handle this event: like halting the overall engine process.	5 years ago
Mike Frysinger	c45cffdbe1	sim: callback: add a getpid interface Rather than hit the OS interface directly, use the existing callback layer so the instantiator can decide behavior.	5 years ago
Mike Frysinger	2fbe9507bf	sim: callback: convert FS interfaces to 64-bit 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.	5 years ago
Mike Frysinger	00330cd18a	sim: callback: convert time interface to 64-bit 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.	5 years ago
Mike Frysinger	64654371d6	sim: callback: inline PTR define We require C11 now, so no need for these pre-ANSI C hacks. PTR is simply void*, so use that directly.	5 years ago
Mike Frysinger	7fb6dc36bb	sim: callback: use ATTRIBUTE_NORETURN This define is handled by ansidecl.h, so no need to duplicate effort.	5 years ago
Mike Frysinger	2e4885ee8f	sim: callback: always include necessary headers We use types from these headers, so always include them.	5 years ago
Mike Frysinger	df68e12b3b	sim: create header namespace 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.	5 years ago
