Remove ioctl-based procfs support on Solaris
This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h. (NEW_PROC_API): Remove. (prsysent_t, pr_sigset_t, pr_sigaction64_t, pr_siginfo64_t): Likewise. * common/common.m4 (GDB_AC_COMMON): Don't check for sys/syscall.h. * configure: Regenerate. * config.in: Regenerate. * gdbserver/configure: Regenerate. * gdbserver/config.in: Regenerate. * i386-sol2-nat.c (_initialize_amd64_sol2_nat): Remove NEW_PROC_API test. * sparc-sol2-nat.c (_initialize_sparc_sol2_nat): Likewise. * linux-btrace.c: Remove HAVE_SYS_SYSCALL_H test. * proc-api.c: Remove !NEW_PROC_API support. Remove HAVE_SYS_PROC_H and HAVE_SYS_USER_H tests. Remove tests for macros always defined on Solaris. * proc-events.c: Remove !NEW_PROC_API support. Remove Remove HAVE_SYS_SYSCALL_H, HAVE_SYS_PROC_H and HAVE_SYS_USER_H tests. (init_syscall_table): Remove non-Solaris syscalls. Remove tests for syscalls present on all Solaris versions. Add missing Solaris 10+ syscalls. (signal_table): Remove non-Solaris signals. Remove tests for signals present on all Solaris versions. (fault_table): Remove non-Solaris faults. Remove tests for faults present on all Solaris versions. * proc-flags.c: Remove !NEW_PROC_API support. (pr_flag_table): Remove non-Solaris and pre-Solaris 7 comments. Remove non-Solaris flags. * proc-why.c: Remove !NEW_PROC_API support. (pr_why_table): Remove meaningless comments. Remove tests for reasons present on all Solaris versions. Remove OSF/1 cases. (proc_prettyfprint_why): Likewise. * procfs.c: Remove !NEW_PROC_API and DYNAMIC_SYSCALLS support. Remove HAVE_SYS_FAULT_H and HAVE_SYS_SYSCALL_H tests. Remove WA_READ test, IRIX watchpoint support. (gdb_sigset_t, gdb_sigaction_t, gdb_siginfo_t): Replace by base types. Change users. (gdb_praddset, gdb_prdelset, gdb_premptysysset, gdb_praddsysset) (gdb_prdelset, gdb_pr_issyssetmember): Replace by base macros. Change callers. Remove CTL_PROC_NAME_FMT tests. (gdb_prstatus_t, gdb_lwpstatus_t): Replace by base types. Change users. (sysset_t_size): Remove. Use sizeof (sysset_t) in callers. Remove PROCFS_DONT_PIOCSSIG_CURSIG support.
