Martin Cracauer a7674320e9 On FPU exceptions, pass a useful error code (one of the FPE_... ... macros) to the signal handler, for old-style BSD signal handlers as the second (int) argument, for SA_SIGINFO signal handlers as siginfo_t->si_code. This is source-compatible with Solaris, except that we have no <siginfo.h> (which isn't even mentioned in POSIX 1003.1b). An rather complete example program is at http://www3.cons.org/cracauer/freebsd-signal.c This will be added to the regression tests in src/. This commit also adds code to disable the (hardware) FPU from userconfig, so that you can use a software FP emulator on a machine that has hardware floating point. See LINT.		1999-07-25 13:16:09 +00:00
