Created attachment 150016 [details] Proposed patch to fix the problem In the man page for cacosh, casinh, etc, in the description of the branch cuts, sometimes sqrt(-1) is denoted by i, and sometimes by I. Probably it would be best to denote it by 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.
