Having this be a config option doesn't make sense: the code size is
pretty much the same (as all the logic is still active), and if it's
disabled, the sim throws an error if you try to use it. That means
we can't break sims that weren't using it before by enabling it all
the time.
Since --trace-debug is for people hacking on the sim sources rather than
people just using the sim, default it to off. This matches the behavior
of other debug knobs we have.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
* sim-options.c (STANDARD_OPTIONS): New member OPTION_SYSROOT.
(standard_options): Support --sysroot=<path>.
(standard_option_handler): Handle OPTION_SYSROOT.
* syscall.c (simulator_sysroot): Define, initialized empty.
(get_path): Prepend simulator_sysroot to absolute file path.
[HAVE_STRING_H]: Include string.h.
[!HAVE_STRING_H && HAVE_STRINGS_H]: Include strings.h.
* nrun.c [HAVE_UNISTD_H]: Include unistd.h.
(main): If simulator_sysroot is not empty, chdir there.
* sim-config.h (simulator_sysroot): Declare.
Add file sim-hload.c - generic load for hardware only simulators.
Review each simulators sim_open, sim_load, sim_create_inferior so that
they more closely match required behavour.
that image properties such as endianness can be checked.
More strongly document the expected behavour of each of the sim_*
interfaces.
Add default endian argument to simulator config macro
SIM_AC_OPTION_ENDIAN. Use in sim_config.
