This attribute is intended to be used only by the code generator and LTO to allow the linker to decide whether the global needs to be in the symbol table. It should probably not be used in optimizations, as the value may have uses outside the module; use hasGlobalUnnamedAddr() instead.

Return true if the currently visible definition of this global (if any) is exactly the definition we will see at runtime.
Non-exact linkage types inhibits most non-inlining IPO, since a differently optimized variant of the same function can have different observable or undefined behavior than in the variant currently visible. For instance, we could have started with
void foo(int *v) { int t = 5 / v[0]; (void) t; }
and "refined" it to
void foo(int *v) { }
However, we cannot infer readnone for foo, since that would justify DSE'ing a store to v[0] across a call to foo, which can cause undefined behavior if the linker replaces the actual call destination with the unoptimized foo.
Inlining is okay across non-exact linkage types as long as they're not interposable (see isInterposable), since in such cases the currently visible variant is a correct implementation of the original source function; it just isn't the only correct implementation.

True if the function's name starts with "llvm.".
This corresponds to the value of Function::isIntrinsic(), which may be true even if Function::intrinsicID() returns Intrinsic::not_intrinsic.

The intrinsic ID for this subclass (which must be a Function).
This member is defined by this class, but not used for anything. Subclasses can use it to store their intrinsic ID, if they have one.
This is stored here to save space in Function on 64-bit hosts.
