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".

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.

GDB and SIM both have functions called "debug_printf", which conflicts
at link time. This commit shadows SIM's debug_printf with a macro so
that SIM's symbol ends up being called "sim_debug_printf".

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.

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.

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.

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.

If we want to run a simple ELF, the reset vector isn't set up, so starting
at address 0 doesn't make sense. Use the ELF's entry point instead.

It is rare for people to want to modify the cmd arg. In general, they
really shouldn't be, but a few still do. For those who misbehave, dupe
the string locally so they can bang on it.

There's no need for the prog_name handed down to the core to be mutable,
so add const markings to it and all the related funcs.
|

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.

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.

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.

When cross-compiling GDB for PPC, there's a prerequisite "-lz" for psim
that results in a build failure. With such prerequisite, GNU Make will
try to search the library from build machine's /usr/lib which is wrong.
On 64-bit Linux build machines the compilation will fail because of this.
