* Add the mlockall() and munlockall() system calls.bms2003-08-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | - All those diffs to syscalls.master for each architecture *are* necessary. This needed clarification; the stub code generation for mlockall() was disabled, which would prevent applications from linking to this API (suggested by mux) - Giant has been quoshed. It is no longer held by the code, as the required locking has been pushed down within vm_map.c. - Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES to express their intention explicitly. - Inspected at the vmstat, top and vm pager sysctl stats level. Paging-in activity is occurring correctly, using a test harness. - The RES size for a process may appear to be greater than its SIZE. This is believed to be due to mappings of the same shared library page being wired twice. Further exploration is needed. - Believed to back out of allocations and locks correctly (tested with WITNESS, MUTEX_PROFILING, INVARIANTS and DIAGNOSTIC).

| | | | | | | | | | | | | | | | | | package, a more recent, generalized set of routines. Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now. As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.

| | | | | | | | | | | | | | | | | | | | | | | | | | | o Add a MD header private to libc called _fpmath.h; this header contains bitfield layouts of MD floating-point types. o Add a MI header private to libc called fpmath.h; this header contains bitfield layouts of MI floating-point types. o Add private libc variables to lib/libc/$arch/gen/infinity.c for storing NaN values. o Add __double_t and __float_t to <machine/_types.h>, and provide double_t and float_t typedefs in <math.h>. o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF, HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to <math.h> and others (FLT_EVAL_METHOD, DECIMAL_DIG) to <float.h> via <machine/float.h>. o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based on the size of its argument. __fpclassifyl() is never called on alpha because (sizeof(long double) == sizeof(double)), which is good since __fpclassifyl() can't deal with such a small `long double'. This was developed by David Schultz and myself with input from bde and fenner.
