* o Implement C99 classification macros isfinite(), isinf(), isnan(),Mike Barcroft2003-02-121-0/+2
| | | | | | | | | | | | isnormal(). The current isinf() and isnan() are perserved for binary compatibility with 5.0, but new programs will use the macros. o Implement C99 comparison macros isgreater(), isgreaterequal(), isless(), islessequal(), islessgreater(), isunordered().

* Implement fpclassify():Mike Barcroft2003-02-082-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible.

* Undo the ill-conceived breakage of the previous commit and really fix:Jason Evans2000-01-291-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For libc_r renamed syscalls, correct symbol naming from _thread_sys_foo() <-- _foo() to _thread_sys_foo() <-- _foo() <-- foo(). This is necessary for system calls which libc_r doesn't define foo(). Some weak symbols such as poll() are defined twice. From what I understand, depending on one weak symbol or the other to be used is a bad idea. All such weak symbols defined in the libc_r-specific code should therefore be made strong (non-weak?). Simplify PSEUDO() to not define any weak symbols, since they aren't ever needed. alpha/SYS.h: Correct reversed usage of WEAK_ALIAS(), which has reversed arguments from __weak_reference(). Also, fix reversal of symbols, so that syscall foo() is a weak alias for _foo(). Add WEAK_ALIAS() call to PRSYSCALL(), which unlike the i386 version of PRSYSCALL(), is not defined in terms of PSYSCALL(). Make PSEUDO() equivalent to the i386 version.

* Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),Jason Evans2000-01-271-6/+7
| | | | | | | | | | | | | | | | | | | | just use _foo() <-- foo(). In the case of a libpthread that doesn't do call conversion (such as linuxthreads and our upcoming libpthread), this is adequate. In the case of libc_r, we still need three names, which are now _thread_sys_foo() <-- _foo() <-- foo(). Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(), nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo(). Remove all internal libc usage of: creat(), pause(), sleep(), system(), tcdrain(), wait(), and waitpid(). Make thread cancellation fully POSIX-compliant.

* Creating weak symbols doesn't work correctly when building an aout libc.Jason Evans1999-12-242-8/+4
| | | | | | | | | | | | | | | Doing the "right thing" here is difficult, so create two ENTRY points for each function (for example, __setjmp and setjmp are equivalent). This isn't pretty, but it works for both aout and ELF. libc symbol naming needs an overhaul in order to properly support function wrapping, specifically in the case of a real libpthread, and these duplicate entry points should be fixed as part of that overhaul.

* sigset_t change (part 5 of 5)Marcel Moolenaar1999-09-294-34/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ----------------------------- Most of the userland changes are in libc. For both the alpha and the i386 setjmp has been changed to accomodate for the new sigset_t. Internally, libc is mostly rewritten to use the new syscalls. The exception is in compat-43/sigcompat.c The POSIX thread library has also been rewritten to use the new sigset_t. Except, that it currently only handles NSIG signals instead of the maximum _SIG_MAXSIG. This should not be a problem because current applications don't use any signals higher than NSIG. There are version bumps for the following libraries: libdialog libreadline libc libc_r libedit libftpio libss These libraries either a) have one of the modified structures visible in the interface, or b) use sigset_t internally and may cause breakage if new binaries are used against libraries that don't have the sigset_t change. This not an immediate issue, but will be as soon as applications start using the new range to its fullest. NOTE: libncurses already had an version bump and has not been given one now. NOTE: doscmd is a real casualty and has been disconnected for the moment. Reconnection will eventually happen after doscmd has been fixed. I'm aware that being the last one to touch it, I'm automaticly promoted to being maintainer. According to good taste this means that I will receive a badge which either will be glued or mechanically stapled, drilled or otherwise violently forced onto me :-) NOTE: pcvt/vttest cannot be compiled with -traditional. The change cause sys/types to be included along the way which contains the const and volatile modifiers. I don't consider this a solution, but more a workaround.
