| 12 | * This file defines substitutes for the libm functions used in some of the |
| 13 | * compiler-rt implementations, defined in such a way that there is not a direct |
| 14 | * dependency on libm or math.h. Instead, we use the compiler builtin versions |
| 15 | * where available. This reduces our dependencies on the system SDK by foisting |
| 16 | * the responsibility onto the compiler. |
