* We are done providing support for the vax.deraadt2016-03-092-32/+2
| | | | lots of agreement.
* Fix wrong answer if the imaginary part is zero.shadchin2015-12-183-3/+9
| | | | | | NetBSD also turn off this piece of code. ok tb@
* Fix behavior csqrt, should beshadchin2015-12-183-6/+6
| | | | | | | | | | | csqrt(conj(z)) == conj(csqrt(z)) Before csqrt(-4.0 + -0.0i) = 0.0 + 2.0j but should be csqrt(-4.0 + -0.0i) = 0.0 - 2.0j ok tb@, also discussed with daniel@

* From FreeBSD 23397:shadchin2015-11-061-7/+7
| | | | | | | | | | | | | Fixed wrong magic numbers in scaling. hypotf() was very broken for large and small values: hypotf(2.3819765e+38, 2.0416943e+38) was NaN instead of 3.1372484e+38 hypotf(-3.4028235e+38, 3.3886450e+38) was NaN instead of Inf hypotf(-2.8025969e-45, -2.8025969e-45) was 0 instead of 4.2038954e-45 Found by: ucbtest ok miod@
* Move s_signgam.c to PURE_SRCS, so that it also gets built on vax.miod2015-09-181-3/+3

| | | | | it with the intended value, in a defined way. From FreeBSD (Dimitry Andric). ok miod@ deraadt@ kettenis@
* fix a case where ceill() returns 1.0L: in the x86 extended precision formatnaddy2015-08-121-1/+1
| | | | | the fraction part has no implicit bit ok deraadt@
* Make exponents of x and y signed and fix esx and esymartynas2015-07-191-4/+5
| | | | | | | comparisons. The offending input in gfortran's round_4.f90 was nextafterl(0.10000000000000000000135525271560688L, -INFINITY) which caused an ulp addition rather than subtraction. Reported by John Marino @ DragonFlyBSD.
* Adapt previous to extended-precision, and fix single-precision constants.martynas2015-07-161-2/+2

* Signs of cacosh/cacoshf were not always correct (e.g., -1.1 -1.1i),martynas2015-07-162-4/+4
| | | | | | as found by fortran regression tests. Also added some complex regression tests for cacosh, casinh, catanh. Reported by John Marino @ DragonFlyBSD.
* Fix logic botch causing warnings with Clang. Reported by dhill, matchesmiod2015-01-222-12/+12
| | | | similar changes in FreeBSD a few years ago.

* Provide a sparc64 version of sqrtl(3) that simply calls _Qp_sqrt.kettenis2014-09-122-1/+31
| | | | | The generic sqrtl(3) is not nearly accurate enough for quad-precision floating point.

* Extended precision floating-point numbers have an explicit integer part bit.kettenis2014-06-051-11/+10
| | | | | | | Correctly account for this bit, otherwise we'll get the wrong result for some inputs. ok martynas@, daniel@

| | | | | | | | | | commit messages that fixes this says: "it was intentionally left broken as an optimization". right! ok martynas@, daniel@

| | | | | | | this hardware alive is becoming increasingly difficult, and I should heed the message sent by the three disks which have died on me over the last few days. Noone sane will mourn these ports anyway. So long, and thanks for the fish.

| | | | | | | | | | | | | | | | | | | | members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@

* Switch libc and libm to use strong aliases rather than weak aliasesmartynas2013-03-2895-156/+156
| | | | | | | | | | | where appropriate. Among other things makes the symbols consistent across all architectures (notably where ldbl mantissa is 53 bits). While at it, kill unused LINTLIBRARY/PROTOLIB1 cruft which was there to trick lint into recording the right prototypes for aliased functions. Most of the work done at the awesome n2k13 hackathon. Agreed by kettenis@, guenther@, matthew@.
