@cindex jit-intrinsic.h
Intrinsics are functions that are provided to ease code generation
on platforms that may not be able to perform all operations natively.
For example, on a CPU without a floating-point unit, the back end code
generator will output a call to an intrinsic function when a floating-point
operation is performed. CPU's with a floating-point unit would use
a native instruction instead.
Some platforms may already have appropriate intrinsics (e.g. the ARM
floating-point emulation routines). The back end code generator may choose
to use either the system-supplied intrinsics or the ones supplied by
this library. We supply all of them in our library just in case a
particular platform lacks an appropriate intrinsic.
Some intrinsics have no equivalent in existing system libraries;
particularly those that deal with overflow checking.
Functions that perform overflow checking or which divide integer operands
return a built-in exception code to indicate the type of exception
to be thrown (the caller is responsible for throwing the actual
exception). @xref{Exceptions}, for a list of built-in exception codes.
The following functions are defined in @code{<jit/jit-intrinsic.h>}:

* Special values that indicate "not a number" for floating-point types.
* Visual C++ won't let us compute NaN's at compile time, so we have to
* work around it with a run-time hack.
