[libc++] Replace uses of _LIBCPP_ALWAYS_INLINE by _LIBCPP_INLINE_VISIBILITY

[ldionne]

Summary

We never actually mean to always inline a function -- all the uses of
the macro I could find are actually attempts to control the visibility
of symbols. This is better described by _LIBCPP_INLINE_VISIBILITY, which
is actually always defined the same.

This change is orthogonal to the decision of what we're actually going
to do with _LIBCPP_INLINE_VISIBILITY -- it just simplifies things by
having one canonical way of doing things.

[ldionne]

Note that even in case we end up renaming _LIBCPP_INLINE_VISIBILITY to something else, this patch is useful because it ensures that nothing was _actually_ meant to be always inline. So any potential rename can then be just that -- a mechanical rename with no potential for semantic change.

[dexonsmith]

FWIW, this change LGTM... but I wouldn't mind hearing from Eric or Marshall before commit.

libcxx/include/any

107–115

It's possible that this (and other __throw_* functions) were trying to force inlining (i.e., not just controlling visibility). However, if so, I disagree with it; I'd rather trust the optimizer to do the right thing.

[ldionne]

libcxx/include/any

107–115

What would be the reason for wanting to always inline that?

[dexonsmith]

libcxx/include/any

107–115

Hypothetically, I've seen always_inline used to force things to be inlined where people don't trust the optimizer. I'm not sure if it was used that way here... but given that we have a macro called _LIBCCP_ALWAYS_INLINE, I suspect that was the intention at some point for some of the uses.

[EricWF]

LGTM.

I meant to do this earlier, but I figured Howard had a specific difference in mind between _LIBCPP_ALWAYS_INLINE and _LIBCPP_INLINE_VISIBILITY, and I wanted to discover that difference.
But the more I think about this, the less sense _LIBCPP_ALWAYS_INLINE current makes.

[ldionne]

Note that this revision also removes _LIBCPP_ALWAYS_INLINE because it is not used anymore and I want to avoid any potential confusion. If we do come around a need to mark something as always inline in the future, we should reintroduce the macro for that use case. I'm not sure such a use case will come any time soon, though.

[erikvanderpoel]

Thank you for doing this!

The lldb bot started failing very recently and the blamelist hints at this change.

http://green.lab.llvm.org/green/job/lldb-cmake/7777/

Can you please take a look?

For your convenience, this is failing building LibCxx testcases with a linker error:

Build Command Output:
Undefined symbols for architecture x86_64:

Interesting. The failing jobs all have things like this:

#include <string>
#ifdef _LIBCPP_INLINE_VISIBILITY
#undef _LIBCPP_INLINE_VISIBILITY
#endif
#define _LIBCPP_INLINE_VISIBILITY
#include <map>
#include <vector>

We should revert to green, but... why is LLDB doing that?

[ldionne]

I reverted this commit. Sorry for the blunder. I'll take a look at why LLDB's tests are doing this.

[ldionne]

This revision to the patch fixes a problem where __pbump had been applied
_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY instead of _LIBCPP_INLINE_VISIBILITY,
which caused the symbols exported in the ABI to change and broke the CI.

Independently, LLDB tests that were failing because they relied on
_LIBCPP_INLINE_VISIBILITY were fixed so that this change should not
break them again.

I still haven't been able to run the ABI tests locally (they fail on my
machine), and I'd like to do that before I submit this patch.

[ldionne]

libcxx/include/streambuf

261

This one was marked as _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY instead of _LIBCPP_INLINE_VISIBILITY in the previous revision. This is what caused the check-cxx-abilist test to fail.

[ldionne]

I've now managed to run the check-cxx-abilist test on my machine and it passes. I'd like to commit this again, @EricWF am I good to go?

[ldionne]

Pushing since I got an offline O.K. from Eric.

libcxx/docs/DesignDocs/VisibilityMacros.rst

**_LIBCPP_OVERRIDABLE_FUNC_VIS**
   **Windows Behavior**: Any symbol marked `dllimport` cannot be overridden
   locally, since `dllimport` indicates the symbol should be bound to a separate
   DLL. All `operator new` and `operator delete` overloads are required to be
   locally overridable, and therefore must not be marked `dllimport`. On Windows,
   this macro therefore expands to `__declspec(dllexport)` when building the
   library and has an empty definition otherwise.
 
 **_LIBCPP_INLINE_VISIBILITY**
-  Mark a function as hidden and force inlining whenever possible.
-
-**_LIBCPP_ALWAYS_INLINE**
-  A synonym for `_LIBCPP_INLINE_VISIBILITY`
+  Mark a function as not being part of the ABI of any final linked image that
+  uses it, and also as being internal to each TU that uses that function. In
+  other words, the address of a function marked with this attribute is not
+  guaranteed to be the same across translation units.
 
 **_LIBCPP_TYPE_VIS**
   Mark a type's typeinfo, vtable and members as having default visibility.
   This attribute cannot be used on class templates.
 
 **_LIBCPP_TEMPLATE_VIS**
   Mark a type's typeinfo and vtable as having default visibility.
   This macro has no effect on the visibility of the type's member functions.
