This procfs.c (and friends) cleanup patch grew along a couple of lines: * First I noticed that PR_MODEL_NATIVE is always defined now that Solaris 10 is the minimum supported version. * Then there was a cleanup that I'd missed when removing support for !NEW_PROC_API, IRIX, and Tru64 UNIX: given that sysset_t is no longer dynamic, there's no need for the special sysset_t_alloc, but we can just use XNEW instead. * Then I found one of those ARI warning mails on gdb-patches, discovered how to run it myself and fixed a large number of the warnings, among them all uses of sprintf. I had to silence the warnings in only 3 instances of the same issue, namely references to LDT in function names which are due to the libthread_db API. * Even so, there were several formatting glitches, like braces around single statements in an if, which I chose to fix while I was at it. The result has been tested on amd64-pc-solaris2.11 and amd64-pc-solaris2.11. * proc-utils.h (PROC_CTL_WORD_TYPE): Remove. * procfs.c: Don't check for PR_MODEL_NATIVE definition. * sparc-sol2-nat.c: Likewise. Remove Linux, __arch64__ references. * sol-thread.c (ps_pdmodel): Don't guard definition. * procfs.c: Fix formatting. * procfs.c (sysset_t_alloc): Remove. (create_procinfo): Use XNEW instead of sysset_t_alloc. (procfs_debug_inferior): Likewise. (procfs_set_exec_trap): Likewise. (proc_set_traced_sysentry): Don't allocate argp dynamically. (proc_set_traced_sysexit): Likewise. * procfs.c (create_procinfo): Use xsnprintf to fix ARI warning. (dead_procinfo): Likewise. (proc_warn): Likewise. (proc_error): Likewise. (proc_get_LDT_entry): Likewise. (do_attach): Likewise. (procfs_target::pid_to_str): Likewise. (iterate_over_mappings): Likewise. * procfs.c (create_procinfo): Fix ARI warning. (proc_get_status): Likewise. (proc_stop_process): Likewise. (proc_run_process): Likewise. (proc_kill): Likewise. (proc_get_LDT_entry): Likewise. (procfs_find_LDT_entry): Likewise. (proc_update_threads): Likewise. (proc_iterate_over_threads): Likewise. (do_attach): Likewise. (procfs_xfer_memory): Likewise. (invalidate_cache): Likewise. (procfs_target::resume): Likewise. (procfs_init_inferior): Likewise. (procfs_set_exec_trap): Likewise. (procfs_target::thread_alive): Likewise. (procfs_target::pid_to_exec_file): Likewise. (iterate_over_mappings): Likewise. (procfs_target::make_corefile_notes): Likewise. * sol-thread.c (sol_thread_target::thread_alive): Likewise. * procfs.c (procfs_find_LDT_entry): Silence ARI warning. (procfs_find_LDT_entry): Likewise. * sol-thread.c (ps_lgetLDT): Likewise.
