thorpej 8969ba6ff5 Build _isinfl() and _isnanl(). 2003-05-17 15:05:52 +00:00
kleink db907cb577 Rename ieee754_function.c to function_ieee754.c, following the convention 
used in exec_format.c, loadfile_format.c, subsys_machdep.c etc.
Per discussion with Christos.

kleink 3b364b9b85 Make sure we reference getcontext() by its internal name. 2003-04-07 21:04:20 +00:00
nathanw 4fb740b8de Implement pthread_atfork() (in libc, because the required threadlib 
stub behavior is exactly the same as the usual behavior).
 2003-02-13 02:50:48 +00:00
kleink cd9f53e12c Add swapcontext() lint stub. 2003-01-21 20:14:07 +00:00
thorpej 3fdac2b8c5 Merge the nathanw_sa branch. 2003-01-18 10:52:16 +00:00
thorpej c061e6bf8b Enable the libc-provided signal trampoline. The old __sigaction14 
entry point has been replaced by the new __sigaction14() which is a
wrapper around the __sigaction_sigtramp system call (which is itself
not directly exposed outside of libc).

No shared library version change is necessary; no new symbols
are exposed outside of libc.
 2002-07-10 04:29:05 +00:00
thorpej 8aa4d3caec New __sigaction14() system call stub which registers the signal 
trampoline, and the signal trampolines themselves.

NOTE: These are not yet enabled; they will be enabled after further
testing on more architectures.

simonb 2d8577fb83 Clean up some rampant code duplication wrt ieee number handling: 
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).

ross de50fe2e64 Drink ALL the Kool-Aid. 
(Move -mieee from lib/ to bsd.*.mk; new var MKIEEEFP defaults to yes.)
 2002-01-27 23:33:51 +00:00
thorpej 4586df0992 On Alpha, build libc and libm with -mieee ... A metric crapload 
of 3rd party software expects this.

XXX TODO: consider libm-fast for alpha that is not -mieee.  Possibly
determine -mieee or not at run-time based on a bit in the executable
headers.

Closes port-alpha/10065

thorpej ac8c1c29e9 * Add WSYSCALL() to SYS.h, which creates a system call with an 
internal name and a weak alias for the name.
* Add a WEAKASM syscall list, and process it.
* Make sysarch() have an internal name (_sysarch()).
 2002-01-14 00:55:55 +00:00
thorpej 5d3e829423 Add internal names for fp{get,set}{mask,round,sticky}(), and 
externally-visible weak aliases for the internal names.

ross 1b16e0e8ee tweak barrier ops some more 2001-04-26 04:18:32 +00:00
ross 18274acbcd Delete the trapb ops bracketing mf_fpcr, they aren't needed. 
Change the trapb ops bracketing mt_fpcr to excb ops.
 2001-04-26 03:23:18 +00:00
ross 0c3b624af9 Complete rewrite. Call the new sysarch(ALPHA_FPGETSTICKY, ...). 2001-04-26 03:21:39 +00:00
ross 91a26b1052 remove the trapb ops bracketing mf_fpcr, in this one case they aren't needed 2001-04-26 03:19:10 +00:00

kleink 82fd76bb06 Need an internal name for pipe(2). 2000-09-28 08:38:53 +00:00
thorpej 9c5afcb2f0 Move the Alpha _mcount() into a .S file so that it can be 
pre-processed, like other Alpha assembly files.
 2000-09-05 16:28:30 +00:00
itohy af83a97717 Add special treatment of shmat(2). 
On m68k ELF calling standard (__SVR4_ABI__), if a function
returns a pointer, the return value should go to a0 as well as d0.
 2000-07-07 08:20:50 +00:00
kleink b8a4d7adf9 Need an internal name for fork(). 2000-06-26 06:32:54 +00:00
kleink 15bc7ed349 Thinko in previous: we do always use an internal name. 2000-06-26 06:25:36 +00:00
kleink 03f996bd0c Add internal names for brk() and sbrk(). 2000-06-23 15:40:36 +00:00
cgd db755e7c76 sweep of my licenses (userland files w/o only my copyright) for 
consistency.  (no functional changes)
 2000-06-14 17:24:02 +00:00
cgd d220ca5ba3 fix up NetBSD RCS Ids to match the standard, and the leading comment as 
to match as well.  No functional changes.

PR standards/9482.

mycroft c26054b799 Delint. 2000-01-22 22:40:58 +00:00
kleink 11e6c54cfc C99: Define a NAN macro in <math.h> which evaulates to a constant expression of 
a single-precision quiet NaN; only to be defined on platforms that do support
this value.
 1999-12-23 10:15:05 +00:00
mycroft b3b07a4c6e Another microoptimization. Take advantage of the addition already having set 
the flags for the <=0 comparison.
 1999-08-30 18:28:24 +00:00
mycroft 0560606383 Reuse the trick of loading 0.0 (rather than 1.0) and then modifying the 
exponent.  It's a bit faster on some machines.
 1999-08-30 18:01:40 +00:00
augustss 75d2dfe657 Remove more unused mulexp variables. 1999-08-30 15:11:32 +00:00
mycroft 5f34ffabca ldexp(denormal, exp>1023) would generate the wrong result in all non-overflow 
cases.  Totally rework this code to fix this bug *and* make it faster.

Inf/NaN case.
 1999-08-29 18:30:14 +00:00
mycroft 17030e8106 Separate isnan() into a separate module, and make isinf()/isnan() use ieee.h. 1999-08-29 18:08:27 +00:00
