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.

* sim/callback.h (struct host_callback_struct): Add ATTRIBUTE_PRINTF
to printf functions.
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.

2021-06-24 Mike Frysinger <vapier@gentoo.org>
* sim/callback.h (struct host_callback_struct): Add arg5, arg6, and
arg7.
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.

2021-06-23 Mike Frysinger <vapier@gentoo.org>
* sim/callback.h (struct host_callback_struct): Add kill.
sim: callback: add a getpid interface Rather than hit the OS interface directly, use the existing callback layer so the instantiator can decide behavior.

2021-06-22 Mike Frysinger <vapier@gentoo.org>
* sim/callback.h (struct host_callback_struct): Add getpid.
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.

2021-05-14 Mike Frysinger <vapier@gentoo.org>
* sim/callback.h (struct host_callback_struct): Change lseek return and
3rd arg to int64_t. Change truncate & ftruncate 3rd arg to int64_t.
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.
2021-04-25 02:35:14 +08:00
2021-05-14 Mike Frysinger <vapier@gentoo.org>
* callback.h: Include stdint.h.
(struct host_callback_struct): Change time return to int64_t. Delete
2nd arg.
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.
2021-04-25 02:02:07 +08:00
2021-05-14 Mike Frysinger <vapier@gentoo.org>
* callback.h (p1, p2): Change PTR to void*.
(cb_host_to_target_stat): Likewise.
sim: callback: use ATTRIBUTE_NORETURN This define is handled by ansidecl.h, so no need to duplicate effort.
2021-04-25 01:58:04 +08:00
2021-05-14 Mike Frysinger <vapier@gentoo.org>
* callback.h (error): Replace __attribute__ with ATTRIBUTE_NORETURN.
sim: callback: always include necessary headers We use types from these headers, so always include them.
2021-04-25 01:57:21 +08:00
2021-05-14 Mike Frysinger <vapier@gentoo.org>
* callback.h: Delete va_start define check.
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.
2021-05-12 12:35:54 +08:00
2021-05-14 Mike Frysinger <vapier@gentoo.org>
* callback.h: Moved from ../gdb/callback.h.
* sim.h: Moved from ../gdb/remote-sim.h.
