Representing dllexport/dllimport as distinct linkage types prevents using
these attributes on templates and inline functions.
Instead of introducing further mixed linkage types to include linkonce and
weak ODR, the old import/export linkage types are replaced with a new
separate visibility-like specifier:
define available_externally dllimport void @f() {}
@Var = dllexport global i32 1, align 4
Linkage for dllexported globals and functions is now equal to their linkage
without dllexport. Imported globals and functions must be either
declarations with external linkage, or definitions with
AvailableExternallyLinkage.

|
* the LLVM intermediate representation as well as other related types
|
|
* and utilities.
|
|
*
|
|
* LLVM uses a polymorphic type hierarchy which C cannot represent, therefore
|
|
* parameters must be passed as base types. Despite the declared types, most
|
|
* of the functions provided operate only on branches of the type hierarchy.
|
|
* The declared parameter names are descriptive and specify which type is
|
|
* required. Additionally, each type hierarchy is documented along with the
|
|
* functions that operate upon it. For more detail, refer to LLVM's C++ code.
|
|
* If in doubt, refer to Core.cpp, which performs parameter downcasts in the
|
|
* form unwrap<RequiredType>(Param).
|
|
*
|
|
* Many exotic languages can interoperate with C code but have a harder time
|
|
* with C++ due to name mangling. So in addition to C, this interface enables
|
|
* tools written in such languages.
