* Clean out the leftovers from the i386_set_gsbase() TLS conversion.peter2005-06-291-18/+1
| | | | | | | | Like on libthr, there is an i386_set_gsbase() stub implementation here to avoid libc.so.5 issues. This should likely be a weak symbol and I expect this will be fixed soon. Approved by: re

This makes it possible to say `mantissa & ~LDBL_NBIT' in places that previously used an #ifdef to select the right expression. The optimizer should dispense with the extra arithmetic when LDBL_NBIT is 0.

| | | | | | | | | can't use the i386_set_ldt() family of routines, because they are not implemented. Instead, use the recently exposed direct access sysarch routines for setting what %fs and %gs point to. Use this for the i386 TLS _set_tp() routine, but only when compiling to run as a 32 bit support binary for amd64 kernels.

| | | | | | | | | | | | | | | | | | | | | isnormal() the hard way, rather than relying on fpclassify(). This is a lose in the sense that we need a total of 12 functions, but it is necessary for binary compatibility because we have never bumped libm's major version number. In particular, isinf(), isnan(), and isnanf() were BSD libc functions before they were C99 macros, so we can't reimplement them in terms of fpclassify() without adding a dependency on libc.so.5. I have tried to arrange things so that programs that could be compiled in FreeBSD 4.X will generate the same external references when compiled in 5.X. At the same time, the new macros should remain C99-compliant. The isinf() and isnan() functions remain in libc for historical reasons; however, I have moved the functions that implement the macros isfinite() and isnormal() to libm where they belong. Moreover, half a dozen MD versions of isinf() and isnan() have been replaced with MI versions that work equally well. Prodded by: kris

* Make getcontext(2) work on i386. It needs a small wrapper in libcpeter2003-09-042-2/+52
| | | | | | | | | | | | | | | | | | | | | | | otherwise the return from the syscall stub for getcontext will pop off the return value for the caller to the getcontext stub and it will appear as though the setcontext() syscall returned instead of the getcontext(). The same bug exists on amd64, a fix is coming there too. The bug can be demonstrated with this test code fragment: main() { ucontext_t top; if (getcontext(&top) == 0) { write(2, "PING!\n", 6); /* Cause a return value of 1 from getcontext this time */ top.uc_mcontext.mc_eax = 1; setcontext(&top); err(1, "setcontext() returned"); } write(2, "PONG!\n", 6); _exit(0); }
* 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).

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.
