// attributes in LLVM IR as well as native dependencies (in C these
|
||||
// correspond to `__declspec(dllimport)`).
|
||||
//
|
||||
// LD (BFD) in MinGW mode can often correctly guess `dllexport` but
|
||||
// relying on that can result in issues like #50176.
|
||||
// LLD won't support that and expects symbols with proper attributes.
|
||||
// Because of that we make MinGW target emit dllexport just like MSVC.
|
||||
// When it comes to dllimport we use it for constants but for functions
|
||||
// rely on the linker to do the right thing. Opposed to dllexport this
|
||||
// task is easy for them (both LD and LLD) and allows us to easily use
|
||||
// symbols from static libraries in shared libraries.
|
||||
//
|
||||
// Whenever a dynamic library is built on Windows it must have its public
|
||||
// interface specified by functions tagged with `dllexport` or otherwise
|
||||
// they're not available to be linked against. This poses a few problems
|
||||
// for the compiler, some of which are somewhat fundamental, but we use
|
||||
// the `use_dll_storage_attrs` variable below to attach the `dllexport`
|
||||
// attribute to all LLVM functions that are exported e.g., they're
|
||||
// already tagged with external linkage). This is suboptimal for a few
|
||||
// reasons:
|
||||
//
|
||||
// * If an object file will never be included in a dynamic library,
|
||||
// there's no need to attach the dllexport attribute. Most object
|
||||
// files in Rust are not destined to become part of a dll as binaries
|
||||
// are statically linked by default.
|
||||
// * If the compiler is emitting both an rlib and a dylib, the same
|
||||
// source object file is currently used but with MSVC this may be less
|
||||
// feasible. The compiler may be able to get around this, but it may
|
||||
// involve some invasive changes to deal with this.
|
||||
//
|
||||
// The flipside of this situation is that whenever you link to a dll and
|
||||
// you import a function from it, the import should be tagged with
|
||||
// `dllimport`. At this time, however, the compiler does not emit
|
||||
// `dllimport` for any declarations other than constants (where it is
|
||||
// required), which is again suboptimal for even more reasons!
|
||||
//
|
||||
// * Calling a function imported from another dll without using
|
||||
// `dllimport` causes the linker/compiler to have extra overhead (one
|
||||
// `jmp` instruction on x86) when calling the function.
|
||||
// * The same object file may be used in different circumstances, so a
|
||||
// function may be imported from a dll if the object is linked into a
|
||||
// dll, but it may be just linked against if linked into an rlib.
|
||||
// * The compiler has no knowledge about whether native functions should
|
||||
// be tagged dllimport or not.
|
||||
//
|
||||
// For now the compiler takes the perf hit (I do not have any numbers to
|
||||
// this effect) by marking very little as `dllimport` and praying the
|
||||
// linker will take care of everything. Fixing this problem will likely
|
||||
// require adding a few attributes to Rust itself (feature gated at the
|
||||
// start) and then strongly recommending static linkage on Windows!
