2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+1
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2023-01-16sim: formally assume unistd.h always exists (via gnulib)Mike Frysinger1-2/+0
We have many uses of unistd.h that are unprotected by HAVE_UNISTD_H, so this is more formalizing the reality that we require this header. Since we switched to gnulib, it guarantees that a unistd.h exists for us to include, so we're doubly OK.
2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-05-13sim: remove use of PTRAlan Modra1-1/+1
PTR will soon disappear from ansidecl.h. Remove uses in sim. Where a PTR cast is used in assignment or function args to a void* I've simply removed the unnecessary (in C) cast rather than replacing with (void *).
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1
This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
2021-12-04sim: include stdint.h when neededMike Frysinger1-0/+1
Avoid implicit include deps with this to help untangle sim headers so we can get rid of arch-specific sim-main.h.
2021-12-04sim: reorder header includesMike Frysinger1-11/+12
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
2021-11-16sim: callback: expose argv & environMike Frysinger1-0/+2
Pass the existing strings data to the callbacks so that common libgloss syscalls can be implemented (which we'll do shortly).
2021-10-31sim: nltvals: localize TARGET_<open> definesMike Frysinger1-14/+28
Code should not be using these directly, instead they should be resolving these dynamically via the open_map. Rework the common callback code that was using the defines to use symbolic names instead, and localize some of the defines in the ARM code (since it's a bit unclear how many different APIs it supports currently), then remove the defines out of the header so no new code can rely on them.
2021-06-29sim: callback: add check for HAVE_KILLMike Frysinger1-0/+5
Fix building on systems w/out a kill function (e.g. Windows).
2021-06-29sim: callback: drop unused printf helpersMike Frysinger1-59/+2
These cover functions aren't used anywhere, so drop them. There was one caller, but it's old DOS code that most likely hasn't been tested in years, so just delete that too.
2021-06-23sim: callback: add a kill interfaceMike Frysinger1-0/+11
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.
2021-06-22sim: callback: add missing cb_target_to_host_signalMike Frysinger1-0/+13
There's been a prototype for this forever, but the implementation was missing. Probably because there weren't any callers, but we'll start using it to implement the kill function.
2021-06-22sim: callback: generate signal mapMike Frysinger1-0/+3
We've been generating the syscall/errno/open maps, but not the signal map, even though we've been including them in the source constants.
2021-06-22sim: callback: add a getpid interfaceMike Frysinger1-0/+13
Rather than hit the OS interface directly, use the existing callback layer so the instantiator can decide behavior.
2021-05-16sim: switch config.h usage to defs.hMike Frysinger1-3/+3
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.
2021-05-14sim: callback: convert FS interfaces to 64-bitMike Frysinger1-5/+5
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 Frysinger1-5/+5
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 Frysinger1-1/+1
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 Frysinger1-1/+1
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.
2021-05-02sim: replace custom attributes with ansidecl.hMike Frysinger1-4/+1
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: callback: inline wrap helperMike Frysinger1-25/+59
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.
2021-04-22sim: sprinkle some ATTRIBUTE_PRINTFSimon Marchi1-4/+4
Add some ATTRIBUTE_PRINTF attributes to functions that take a format string, to fix a few -Wformat-nonliteral warnings. Use the ATTRIBUTE_PRINTF macro like we use in GDB, instead of spelling out __attribute__((format...)). Use ATTRIBUTE_NULL_PRINTF at one place, because callers expect to be able to pass NULL. sim/common/ChangeLog: * callback.c (os_printf_filtered, os_vprintf_filtered, os_evprintf_filtered, os_error): Use ATTRIBUTE_PRINTF. * sim-engine.h (sim_engine_abort, sim_engine_vabort): Likewise. * sim-events.h (sim_events_schedule_tracef, sim_events_schedule_vtracef): Use ATTRIBUTE_NULL_PRINTF. Change-Id: Icd206f7b2c325e8b144f72eb129fb2a6b5af2fa3
2021-01-11sim: clean up C11 header includesMike Frysinger1-10/+0
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.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

2016-01-09sim: drop common/cconfig.h in favor of a single config.hMike Frysinger1-2/+1
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.

2015-06-18sim: callback: fix sentinel testing when walking mapsMike Frysinger1-2/+2
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: callback: add human readable strings for debugging to mapsMike Frysinger1-12/+82
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.

Most of these prototypes have been killed off, but we have a few left in the sim tree. Clean them up so we can enable the -W flag for it.
