//go:build darwin && (amd64 || arm64)
#include "textflag.h"
// fsevents_darwin_ffi.s: shared (amd64+arm64) assembly trampolines
//
// Provides JMP trampolines for CoreFoundation, libdispatch, and CoreServices
// functions imported via //go:cgo_import_dynamic. Each trampoline is paired
// with a GLOBL/DATA address that makes the ABI0 entry point available as a
// Go uintptr, following the pattern used by golang.org/x/sys/unix/
// zsyscall_darwin_*.s.
//
// Arch-specific trampolines (FSEventStreamCreate and the FSEvents callback)
// live in fsevents_darwin_ffi_{amd64,arm64}.s.
// Each TEXT trampoline JMPs to the corresponding cgo_import_dynamic symbol.
// JMP is a Go pseudo-instruction that works on all architectures.
//
// Trampoline TEXT symbols are file-scoped (`<>` suffix); there is no
// Go-side declaration for them. Only the `_addr` variables (declared
// `·name(SB)` for package-scope) are visible from Go. Following the
// pattern used by golang.org/x/sys/unix/zsyscall_darwin_*.s.
//
// Each trampoline is paired with its GLOBL/DATA address, which makes the
// ABI0 address of the trampoline available as a Go uintptr.
