For want of any better definition, inline asm goes "everywhere" the same as it
|
|
if it were in a header (with the disadvantage that the inline asm will be
|
|
included in the program if the module is used, even if the header containing
|
|
the inline asm is never included - unlike a non-modular build).
|
|
|
|
This is inconsistent with how namespace scope static variables are handled -
|
|
where they only appear in the code that includes a header. This functionality
|
|
was implemented to workaround/support the initialization of iostreams
|
|
(implemented as a namespace scope static in the header - only to be provided
|
|
when that specific header is included in the program).

Test that implicit special members are emitted into the FOO module if they're
|
|
ODR used there, otherwise emit them linkonce_odr as usual in the use.

FIXME: Proactively instantiate any valid implicit special members to emit them into the module object.

Modular debug info puts the definition of a class defined in a module in that
|
|
module's object. Users of the module only get a declaration.
|

'distinct' is used for definition records (the flags field is empty/unspecified)
|
|
FOO: = distinct !DICompositeType(tag: DW_TAG_structure_type, name: "implicit_dtor"
|

Declarations are non-distinct and include the 'DIFlagFwdDecl' flag.
