// Function accessor backed by a function-local static (Meyers singleton).
|
|
// Avoids the static-initialization-order fiasco that the previous
|
|
// `extern IPlatformInput& PlatformInput;` form had: anything reading
|
|
// PlatformInput during another translation unit's static init was UB.
|
|
//
|
|
// The macro lets the existing call sites keep writing `PlatformInput.foo()`
|
|
// without each call site having to add the `()`. The expansion is just
|
|
// a call to a function returning a reference, so codegen is unchanged
|
|
// once inlined.
