sim: syscall: unify memory helpers Almost every port implements these two callbacks in the same way, so unify them in the common layer.

/* Simulator system call support.
Update copyright year range in all GDB files. This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

sim: syscall: add common sim_syscall helpers Many ports have the same sim syscall logic, so add some helpers to handle all the common details. The arches still have to deal with the unpacking and packing of the syscall arguments, but the rest of the sim<->callback glue is now shared.

normalized into a single value (like a lot of operating systems do). If you
want the split values, see the other function below.

not the case with these helpers.
