H A Dfloating-point.rst6 Kernel code is normally prohibited from using floating-point (FP) registers or
11 However, occasionally drivers or library functions may need to include FP code.
12 This is supported by isolating the functions containing FP code to a separate
13 translation unit (a separate source file), and saving/restoring the FP register
18 touching the FP registers outside these critical sections. Compilers sometimes
19 use FP registers to optimize inlined ``memcpy`` or variable assignment, as
56 from files implementing FP code (those with their compilation flags adjusted as
57 above). Instead, it must be included when defining the FP critical sections.
