* Add an implementation of IRIX-compatible cacheflush() routine to mips ports,miod2009-09-272-1/+39
| | | | | | | needed for gcc -ftrampoline operation as well as by some third-party software. Although the implementation uses the sysarch() sysctl, the wrapper is added to libc as it was a direct system call (which it is on IRIX).
* Load symbol address with dla, not la; good thing userland is still limitedmiod2009-07-131-2/+2

| | | | | | - remove frexp in hppa64, cloned from hppa - move generic ieee754 implementations of modf and ldexp to gen ok kettenis@, "looks good" millert@

* - add long double signbitmartynas2008-12-0952-55/+348
| | | | | | | | | | | | | - make long double versions weak aliases to double versions, on archs where long doubles are 64 bits - no need to have two finites. finite() and finitef() are non-standard 3BSD obsolete versions of isfinite. remove from libm. make them weak_alias in libc to __isfinite and __isfinitef instead. similarly make 3BSD obsolete versions of isinf, isinff, isnan, isnanf weak_aliases to C99's __isinf, __isinff, __isnan, __isnanf - bump major ok millert@
* Use large pic asm for access to errno (needed for pie). Originally fromkurt2008-09-291-2/+4
| | | | | drahn@ but tweaked to use same scratch reg as PIC_PROLOGUE. okay miod@ drahn@
* - replace dtoa w/ David's gdtoa, version 2008-03-15martynas2008-09-07101-11/+2160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - provide proper dtoa locks - use the real strtof implementation - add strtold, __hdtoa, __hldtoa - add %a/%A support - don't lose precision in printf, don't round to double anymore - implement extended-precision versions of libc functions: fpclassify, isnan, isinf, signbit, isnormal, isfinite, now that the ieee.h is fixed - separate vax versions of strtof, and __hdtoa - add complex math support. added functions: cacos, casin, catan, ccos, csin, ctan, cacosh, casinh, catanh, ccosh, csinh, ctanh, cexp, clog, cabs, cpow, csqrt, carg, cimag, conj, cproj, creal, cacosf, casinf, catanf, ccosf, csinf, ctanf, cacoshf, casinhf, catanhf, ccoshf, csinhf, ctanhf, cexpf, clogf, cabsf, cpowf, csqrtf, cargf, cimagf, conjf, cprojf, crealf - add fdim, fmax, fmin - add log2. (adapted implementation e_log.c. could be more acruate & faster, but it's good enough for now) - remove wrappers & cruft in libm, supposed to work-around mistakes in SVID, etc.; use ieee versions. fixes issues in python 2.6 for djm@ - make _digittoint static - proper definitions for i386, and amd64 in ieee.h - sh, powerpc don't really have extended-precision - add missing definitions for mips64 (quad), m{6,8}k (96-bit) float.h for LDBL_* - merge lead to frac for m{6,8}k, for gdtoa to work properly - add FRAC*BITS & EXT_TO_ARRAY32 definitions in ieee.h, for hdtoa&ldtoa to use - add EXT_IMPLICIT_NBIT definition, which indicates implicit normalization bit - add regression tests for libc: fpclassify and printf - arith.h & gd_qnan.h definitions - update ieee.h: hppa doesn't have quad-precision, hppa64 does - add missing prototypes to gdtoaimp - on 64-bit platforms make sure gdtoa doesn't use a long when it really wants an int - etc., what i may have forgotten... - bump libm major, due to removed&changed symbols - no libc bump, since this is riding on djm's libc major crank from a day ago discussed with / requested by / testing theo, sthen@, djm@, jsg@, merdely@, jsing@, tedu@, brad@, jakemsr@, and others. looks good to millert@ parts of the diff ok kettenis@ this commit does not include: - man page changes
* fix apps that use isinff, isnanf; use ieee 754 mi code, as allmartynas2008-07-253-119/+2
| | | | other ieee fp archs do; pointed out by theo. tested by theo
* - move isinf, isnan dups to gen, since most is ieee 754martynas2008-07-2458-1168/+376
| | | | | | | | | | | | | | | | - is{inf,nan} should be macros for real-floating, so rename to __is{inf,nan}, per C99 - implement C99 __fpclassify(), __fpclassifyf(), __isfinite(), __isfinitef(), __isnormal(), __isnormalf(), __signbit(), __signbitf() - long functions added, but not yet enabled, till ieee.h is fixed - implement vax equivalents of the functions - reimplement isinff, isnanf in a better way, and move to libc - add qnan bytes for all archs - bump major man pages will follow ok millert@. arm bits looked over by drahn@ discussed w/ theo, who showed the right direction, to put these functions in libc
* clear sign bit, instead of comparing to zero and setting x=-x.martynas2008-07-232-41/+34
| | | | | | | fixes special cases, such as neg. zero, and makes C99 conformant ok miod@, millert@ since there's nothing else in arm's fabs.c, replace 4-clause license w/ the one at /usr/share/misc/license.template
* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-2623-184/+23
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

* Change the syscall invocation sequences to no longer fetch the last fewmiod2007-10-242-8/+2
| | | | | | | | | | arguments from the stack, since the kernel will now copyin() them when necessary. This makes all system calls (but mmap()) slightly faster. WARNING! After this commit, your binaries must run against a kernel featuring m88k/m88k/trap.c r1.34 or better - i.e. a 4.1 or later kernel.

* Move landisk to hardware floating point. At the moment the FPU context ismiod2007-03-029-136/+265
| | | | | | | | | | | | | | | always saved upon context switches, as FPU registers are heavily used for long long computations (don't ask). Gcc default to -m4. Credits to drahn@ otto@ and deraadt@ for feedback and help testing. Upgrade procedure if you don't want to use the damn snapshots: - build and install new kernel, reboot off it - build new gcc, do not install it yet - make includes - install new gcc - build and install lib/csu and lib/libc - make build
