Import of original NetBSD's ibcs2 emulator sources by Scott Bartram, which is used as a basis for a more complete and cleaner ibcs2 emulator. (snapshot about May 1995 with a few files from September 1995) Some files and code from old emulator still remains. New files, features, and changes have been implemented by myself, which will be shown in following commits.

sigset_t change (part 4 of 5) ----------------------------- The compatibility code and/or emulators have been updated: iBCS2 now mostly uses the older syscalls. SVR4 now properly handles all signals. This has been achieved by using the new sigset_t throughout the emulator. The Linuxulator has been severely updated. Internally the new Linux sigset_t is made the default. These are then mapped to and from the new FreeBSD sigset_t. Also, rt_sigsuspend has been implemented in the Linuxulator. Implementing this syscall basicly caused all this sigset_t changing in the first place and the syscall has been used throughout the change as a means for testing. It basicly is too much work to undo the implementation so that it can later be added again. A special note on the use of sv_sigtbl and sv_sigsize in struct sysentvec: Every signal larger than sv_sigsize is not translated and is passed on to the signal handler unmodified. Signals in the range 1 upto and including sv_sigsize are translated. The rationale is that only the system defined signals need to be translated. The emulators also have been updated so that the translation tables are only indexed for valid (system defined) signals. This change also fixes the translation bug already in the SVR4 emulator.

Remove old files no longer needed. Add new files created for emulator. Modify NetBSD import to work with FreeBSD and add new features and code. The complete emulator is essentially a combination of work/code implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself, Steven Wallace. Features of this new emulator system include: o "clean" code, including strict prototyping. o Auto-generation of ibcs2 system calls, xenix system calls, isc system calls. Generation includes system tables, structure definitions, and prototyping of function calls. o ibcs2 emulator does not rely on any COMPAT_43 system calls. o embedded socksys support o ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel o alternate /emul/ibcs2 namespace searched first for files in ibcs2 system. Usefull to keep sysv libraries, binaries in /emul/ibcs2. o many other finer details and functions fixed or implemented.

Make MINSIGSTKSZ machine dependent, and have the sigaltstack syscall compare against a variable sv_minsigstksz in struct sysentvec as to properly take the size of the machine- and ABI dependent struct sigframe into account. The SVR4 and iBCS2 modules continue to have a minsigstksz of 8192 to preserve behavior. The real values (if different) are not known at this time. Other ABI modules use the real values. The native MINSIGSTKSZ is now defined as follows: Arch MINSIGSTKSZ ---- ----------- alpha 4096 i386 2048 ia64 12288 Reviewed by: mjacob Suggested by: bde
