<bofh> egg|zzz|egg: vim /usr/include/libgen.h, seems to only contain prototypes for dirname & __xpg_basename in glibc.
<bofh> I am somewhat annoyed, turns out that some code my group uses had a special function impl broken since it was checked in back in 1993, and the issue was entirely "we fucked up mapping [0,8] onto [-1,1]", the actual Chebyshev series used is amazingly good.
<bofh> https://twitter.com/juliagalef/status/952298766987550720 thanks for that clarification there.

<whitequark> oh
<whitequark> I found it
<whitequark> there's mangling for local entities

<egg|work|egg> aah
<whitequark> it's the Z

<egg|work|egg> whitequark: what's that?
<whitequark> mangled function name :p
<egg|work|egg> it seems to confuse demangler.com at least
<whitequark> egg|work|egg: it expands to 4GB+ of signature
<egg|work|egg> whitequark: O_o
<egg|work|egg> whitequark: also it seems I broke demangler.com
<egg|work|egg> whitequark: anyway, maybe this will be nicer on your demangler https://hastebin.com/raw/rojaraweda
<egg|work|egg> hm, maybe not
<whitequark> ZZ...
<egg|work|egg> whitequark: what's that
<whitequark> it starts with ZZ
<whitequark> same problem as before
<egg|work|egg> ah
* UmbralRaptor pokes mathematics in the terminology https://en.m.wikipedia.org/wiki/Near-field_(mathematics)
<egg|work|egg> whitequark: so I should look for things with only one Z?
<whitequark> egg|work|egg: well, they may have Zs in class names or stuff.
<whitequark> but yes.
<egg|work|egg> whitequark: okay, demangler.com chokes on this, but it has only one Z https://hastebin.com/raw/usunemucof
<egg|work|egg> I see some declval
<whitequark> hmmm
<whitequark> declval?
<egg|work|egg> whitequark: so, wild guess, if it says FitHermiteSpline it's probably related to https://github.com/mockingbirdnest/Principia/blob/master/numerics/fit_hermite_spline.hpp#L27
<whitequark> ok I actually found a bug, thanks
<egg|work|egg> whitequark: and Difference has some declval https://github.com/mockingbirdnest/Principia/blob/master/quantities/named_quantities.hpp so maybe that explains it
<whitequark> oh
<egg|work|egg> whitequark: principia is getting good at finding weird bugs
<whitequark> I handle neither expressions (X) or decltype (Dt/DT)
<whitequark> expressions by design, decltype because it's a pain in the ass
<egg|work|egg> ah
<whitequark> well
<whitequark> both of them because they're a pain in the ass
<whitequark> and not really necessary
<egg|work|egg> but what if you want to reverse-engineer principia,
<whitequark> if you're reverse-engineering something that nasty you're pretty fucked anyhow
<egg|work|egg> whitequark: we've filed 3 bugs against MSVC 2017 with our silly codebase
<whitequark> you deserve everything that happens to you
<egg|work|egg> whitequark: one Z only, no DT: https://hastebin.com/raw/izojasoqug (demangler.com also chokes on this one)
<whitequark> that has X
<egg|work|egg> whitequark: no Z, no DT, no X: https://hastebin.com/raw/azularotul
<whitequark> okay, that has a function type in it, but I might just implement that
<whitequark> oh god that worked
<egg|work|egg> whitequark: nice
<whitequark> demangler.com can do that one too though
<egg|work|egg> whitequark: yeah, demangler chokes on the decltypes though
