cacos(3): correct spelling of 'I' In some cases we had 'i' instead of 'I'. PR: 195517 Submitted by: stephen MFC r329259 (by eadler): msun: signed overflow in atan2 As a component of atan2(y, x), the case of x == 1.0 is farmed out to atan(y). The current implementation of this comparison is vulnerable to signed integer underflow (that is, undefined behavior), and it's performed in a somewhat more complicated way than it need be. Change it to not be quite so cute, rather directly comparing the high/low bits of x to the specific IEEE-754 bit pattern that encodes 1.0. Note that while there are three different e_atan* files in the relevant directory, only this one needs fixing. e_atan2f.c already compares against the full bit pattern encoding 1.0f, while e_atan2l.cuses bitwise-ands/ors/nots and so doesn't require a change.

Also required for some numerical codes using complex numbered Hamiltonians. Thanks to jhb for tracking down the issue with making weak_reference compile on powerpc. When asked to review, bde said "I don't like it" - but provided no actionable feedback or superior implementations. Discussed with: jhb Submitted by: jmd Differential Revision: https://reviews.freebsd.org/D15919 MFC r336563: Recommit r336497: Fix powl, cpow, cpowf, and cpowl imports from OpenBSD This is a follow-up to r336299. * lib/msun/Makefile: . Remove polevll.c * lib/msun/ld80/e_powl.c: . Copy contents of polevll.c to here. This is the only consumer of these functions. Make functions 'static inline'. . Make reducl a 'static inline' function. * lib/msun/man/exp.3: . Remove BUGS section that no longer applies. * lib/msun/src/math_private.h: .

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Clang allows us to initialize complex numbers using an array initializer, casted to a complex type. GCC has a builtin called __builtin_complex().

Only use the static assertion when __generic is available.

Mea culpa.

Make _Complex_I a proper float _Complex when using GCC 4.2.

2012-01-05T12:05:48Z

It turns out our GCC has quite an interesting bug: typeof(1.0fi) != float _Complex typeof((float _Complex)1.0fi) != float _Complex typeof((float _Complex)1.0i) == float _Complex In other words: if casting to an equal size, GCC seems to take a shortcut. By casting down from a double to a float, GCC doesn't take this shortcut, yielding the proper type. To prevent foot-shooting, add a _Static_assert() to guarantee that _Complex_I is always a float _Complex. I'm not going to MFC this part of the diff. MFC after: 2 weeks
