Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

|
|
| Takes the result and puts it in where the user expects it.
|
|
| Library functions return result in fp0. If fp0 is not the
|
|
| users destination register then fp0 is moved to the
|
|
| correct floating-point destination register. fp0 and fp1
|
|
| are then restored to the original contents.
|
|
|
|
|
| Input: result in fp0,fp1
|
|
|
|
|
| d2 & a0 should be kept unmodified
|
|
|
|
|
| Output: moves the result to the true destination reg or mem
|
|
|
|
|
| Modifies: destination floating point register
