2015-03-14sim: drop duplicate header checksMike Frysinger52-313/+218
The SIM_AC_COMMON macro already checks for a bunch of headers, so specific sim ports need not do it themselves.
2015-03-14sim: move sim-io.h to sim-assert.hMike Frysinger3-1/+8
Since sim-endian.c doesn't actually use sim_io funcs, it's weird to include the sim-io.h header here. It's doing so only for the assert header. So lets relocate the include to the right place.
2015-03-10sim: bfin: fix up linux-fixed-code.h generation more [PR sim/13160]Mike Frysinger2-1/+7
Add a trailing semi-colon to the sed print command as the BSD sed implementation wants it. It's a nop otherwise and works fine on GNU/etc... implementations too.

2015-03-09sim: bfin: fix up linux-fixed-code.h generation [PR sim/10143]Mike Frysinger2-3/+11
The use of $< ends up picking the wrong object out of the depend list. Specify the input name directly to avoid fragility. On BSD systems, we need to make sure all options come before the non-options (i.e. the files). Reported-by: Chris Johns <chrisj@rtems.org> URL: https://sourceware.org/bugzilla/show_bug.cgi?id=13160

These look like left over hacks from the days where we had to protect ourselves from the compiler and C library. None of these checks are relevant, and we have common configure logic to do header tests. Punt them all now.

Commit 07774fccc3280323f43db9ed204f628503b34663 update the microblaze opcodes table to avoid C++ collisions, but missed updating the sim. That caused it to fail to build due to missing keywords.

2015-01-15Build failure in sim/rx/gdb-if.c on windowsJoel Brobecker2-4/+10
This should fix a build failure reported on x86_64-mingw32 by Daniel Calcoen due to conflicting declarations of "open". This patch just renames the static global in sim/rx/gdb-if.c into "rx_sim_is_open". sim/rx/ChangeLog: * gdb-if.c (open): Rename to... (rx_sim_is_open): This. Replace all uses of "open" by uses of "rx_sim_is_open" throughout. Tested by rebuilding on x86_64-linux.

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.

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.
