This reverts commit 98f14c4cdb.

Same as previous commit.

Behdad Esfahbod 98f14c4cdb Hide symbols in hb-iter
Painful.  All template methods need to be explicitly hidden :(.

Maybe we should switch to -fvisibility=hidden pragma.

A LOT more to go.

Behdad Esfahbod 2bd2750234 [iter] Tweak SFINAE again
Don't think we need hb_is_same().

Behdad Esfahbod d419a9a437 [iter] Use different SFINAE scheme to make MSVC happy
From Orvid King: TLDR; MSVC has some issues using sizeof(declval<T>()) for
SFINAE of templated types, so I just used SFINAE in a different context where
MSVC doesn't have the issue.

Behdad Esfahbod 42ab32cbba [iter] Remove passing pointer to hb_iter()
While doable with hb_deref_pointer() as well, we also would then
need to do it in a ton of places.  Not worth it / messy.

Behdad Esfahbod b6f29bf141 [iter] Accept pointers in hb_iter()
No idea how to avoid dupicating code.  Was hoping hb_deref_pointer()
would do it, but looks like a pointer can't bind to a universal
reference T&&.  Humm.

Behdad Esfahbod 4c38a9f601 Remove hb_assign()
Not needed anymore.  We just use operator= now.
2019-03-29 20:23:07 -07:00
Behdad Esfahbod 3f36c89f2e Inline explicit_operator macro
Now that we require C++11, no need to macro.

I can't reproduce locally, but many of the bots are failing because of this
as well.

It's a pity that operator-> must return pointer.  Ugh.  Why?!
