2014-12-03callback.h:struct host_callback_struct compilation error on Windows hosts.Joel Brobecker7-8/+28
On Windows, a recent gnulib update imported the lstat module, and this caused a remote-sim.c build failure in struct host_callback_struct: In file included from /[...]/gdb/remote-sim.c:34:0: /[...]/gdb/../include/gdb/callback.h:93:9: error: duplicate member '_stati64' int (*lstat) (host_callback *, const char *, struct stat *); ^ What happens it that gnulib's stat.h makes the following defines: /* Large File Support on native Windows. */ #if 1 # define stat _stati64 #endif and then: #if 1 # if ! 0 /* mingw does not support symlinks, therefore it does not have lstat. But without links, stat does just fine. */ # if !(defined __cplusplus && defined GNULIB_NAMESPACE) # define lstat stat # endif So, the following fields in struct host_callback_struct... int (*stat) (host_callback *, const char *, struct stat *); int (*fstat) (host_callback *, int, struct stat *); int (*lstat) (host_callback *, const char *, struct stat *); ... get translated to... int (*_stati64) (host_callback *, const char *, struct _stati64 *); int (*_fstati64) (host_callback *, int, struct _stati64 *); int (*_stati64) (host_callback *, const char *, struct _stati64 *); ... which causes two fields to have the same name. This patch fixes the issue by renaming the stat-related fields by adding a "to_" prefix, similar to what is done in GDB's target_ops vector. include/gdb/ChangeLog: * callback.h (struct host_callback_struct) <to_stat>: Renamed from "stat". <to_fstat>: Renamed from "fstat". <to_lstat>: Renamed from "lstat". sim/common/ChangeLog: * sim-io.c (sim_io_stat, sim_io_fstat): Adjust calls to "stat" and "fstat" callbacks by calls to "to_stat" and "to_fstat" (resp) callbacks following renaming in callback.h. * syscall.c (cb_syscall): Likewise.

2014-11-28Correct fabs and fneg insns in simulatorOleg Endo2-3/+21
It seems that the implementation of the SH fabs and fneg insns in the simulator is not correct. They use the FP_UNARY macro which checks the FPSCR.PR setting and raises an exception if PR = 1 (double precision) and the register number is not even (i.e. a valid DF reg number). For normal unary FP insns this is fine. However, fneg and fabs perform the same (integer) operations regardless of the FPSCR.PR setting. This issue initially popped up here https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63260 I've checked some of the failing tests mentioned in GCC PR 63260 above with the patch applied and the failures go away. sim/sh/ChangeLog (tiny patch): * gencode.c (fabs, fneg): Implement as integer operation instead of using the FP_UNARY macro.

2014-08-23Fix m32r-elf sim, default hardware to off.Hans-Peter Nilsson4-12/+13
The situation here is similar to that of the other nearby (previous) sims fixed; it fails at the dv_sockser_install declaration in sim/m32r/tconfig.in. But, as opposed to e.g. frv, this *does* have a definition of UART_INCHAR_ADDR et al. It's somewhat tempting to keep sim-hardware enabled here but, I'm disabling it for the same reasons as for frv. Unsurprisingly (as m32r seems to be the template), the same confusing lines are in sim/m32r/Makefile.in as in sim/frv/Makefile.in at that time, deleted in 73e76d20. Again, commit 73e76d20 (for m32r as well as for frv) attempted to move the non-existing dv-sockser.o use to $(m32r_extra_objs) but missed that AC_SUBST would only affect @m32r_extra_objs@ and not $(m32r_extra_objs) per se so nothing happened. As for frv, I'm removing the $(m32r_extra_objs) too, to avoid confusion. Make check-sim for m32r-elf shows no regressions (5 failures; 100 expected passes) compared to bf3d9781ec049 (before the recent config.in regen, after sim-hardware mostly-enabled) and eed23bb4a1 (before the sim-hardware mostly-enabled; 2013-03-23). sim/m32r: * configure.ac: Default simulator hardware to off again. Remove dead m32r_extra_objs substitution. * configure: Regenerate. * Makefile.in: Remove unused frv_extra_objs.
2014-08-23Fix sh64-elf sim, default hardware to off.Hans-Peter Nilsson3-15/+9
See nearby (previous) commit for the iq2000 sim; this similarly fails at the dv_sockser_install declaration in sim/sh64/tconfig.in. I'm disabling simulator hardware to be consistent with the state before 94c63d78f (2013-03-23) and with the actions for the frv sim and the iq2000 sim. Make check-sim for sh64-elf shows no regressions (25 failures; 357 expected passes) compared to bf3d9781ec049 (before the recent config.in regen, after sim-hardware mostly-enabled) and eed23bb4a1 (before the sim-hardware mostly-enabled; 2013-03-23). sim/sh64: * configure.ac: Default simulator hardware to off again without emitting errors when off or dv-sockser.o unavailable. * configure: Regenerate.
2014-08-23Fix iq2000-elf sim, default hardware to off.Hans-Peter Nilsson3-15/+9
See nearby (previous) commit for the frv sim; this similarly fails at the dv_sockser_install declaration in sim/iq2000/tconfig.in. There's no HAVE_DV_SOCKSER conditionals here and no other dv-sockser.o artefacts so maybe there is no further fallout, but I'm going to disable sim-hardware just be consistent with the state before 94c63d78f (2013-03-23) and with the actions for the frv sim. Make check-sim for iq2000-elf shows no failures but that's in no small part because it has no test-suite. sim/iq2000: * configure.ac: Default simulator hardware to off again without emitting errors when off or dv-sockser.o unavailable. * configure: Regenerate.
2014-08-23Fix frv-elf sim, default hardware to off.Hans-Peter Nilsson4-12/+13
At 2974be626, frv-elf fails at the dv_sockser_install declaration in sim/frv/tconfig.in. But, with the trivial #include's added (see other sims tconfig.in, like cris or mn10300), it *still* fails building sim/frv/devices.c because of a missing UART_INCHAR_ADDR. I have no insight into what'd be a valid value, except that there's a definition in m32r, which was probably used as a template with frv not finished. Simulated hardware should not have been be enabled, and was indeed not enabled by default before 94c63d78f (2013-03-23), where it seems to have been enabled for no simulator-specific reason. Except dv-sockser.o wasn't enabled even then: sim/frv/config.in wasn't regenerated, so HAVE_DV_SOCKSER was never defined. Maybe people were fooled by this in sim/frv/Makefile.in at that time (these two lines were later deleted, in 73e76d20): CONFIG_DEVICES = dv-sockser.o CONFIG_DEVICES = (As it seems people have missed it before: the second line overrides the first...) I'm guessing these lines were part of the never-completed hardware-support. Commit 73e76d20 attempted to move the imagined dv-sockser.o from $(CONFIG_DEVICES) to $(frv_extra_objs) but missed that AC_SUBST would only affect @frv_extra_objs@ (not $(frv_extra_objs) per se) so nothing happened regarding sockser: dv-sockser.o was not compiled and HAVE_DV_SOCKSER was not defined. I'm removing the $(frv_extra_objs) too, to avoid confusion. The best action seems to be disabling all hardware support by default again until a specific sim maintainer finishes the work. Make check-sim for frv-elf shows no failures after this. sim/frv: * configure.ac: Default simulator hardware to off again. Remove dead frv_extra_objs substitution. * configure: Regenerate. * Makefile.in: Remove unused frv_extra_objs.

2014-02-17 Revise signal mapping function in GDB interface for RX sim.Kevin Buettner2-29/+18
sim/rx/gdb-if.c had a function named `rx_signal_to_host'. This function mapped signal numbers used by the BSP to host signal numbers which, at one time a while back, were used by GDB as target signal numbers. This change updates the signal numbers returned to be those names prefixed with "GDB_SIGNAL_" as defined in include/gdb/signals.h. It also changes the name of the function somewhat to better match what the function currently does. I noticed that this function is not static - and there's no reason for it not to be - so I made it static too. * gdb-if.c (rx_signal_to_host): Rename to `rx_signal_to_gdb_signal'. Make static. Update all callers to use new name. Use signal names from include/gdb/signals.h.
2014-02-17sim: delete duplicate SIGINT handlingMike Frysinger10-57/+31
Many of the simulators change the SIGINT handler. E.g., moxie/interp.c: sigsave = signal (SIGINT, interrupt); However, this is unnecessary. remote-sim.h already provides an API for asynchronously stopping a sim; and both gdb and the drivers (run.c and nrun.c at least, I didn't check the others) install a SIGINT handler which calls this method.
