2023-12-21sim: arm: fix -Wimplicit-fallthrough warningsMike Frysinger1-0/+1
Replace some fall through comments with the attribute.
2023-12-21sim: arm: add missing breaks to SWI processingMike Frysinger1-0/+2
Seems unlikely we want the remove syscall to fallthrough into the rename syscall since we can't rename files that have been removed.
2023-12-07sim: arm: fix -Wunused-but-set-variable warningsMike Frysinger1-2/+0
2023-01-16sim: formally assume unistd.h always exists (via gnulib)Mike Frysinger1-3/+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.
2021-10-31sim: nltvals: localize TARGET_<open> definesMike Frysinger1-6/+11
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.
2021-05-16sim: switch config.h usage to defs.hMike Frysinger1-1/+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 time interface to 64-bitMike Frysinger1-3/+3
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: 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.

These vestiges of the 20 year old emulator are just getting in the way. Punt all the dead code we either don't compile or don't use.
