| Title: Shared Floating Point Support |
| |
| Description: |
| |
| This test uses the background task and a fiber to independently load and |
| store floating point registers and check for corruption. This tests the |
| ability of contexts to safely share floating point hardware resources, even |
| when switching occurs preemptively. |

| Building and Running Project: |
| |
| This nanokernel project outputs to the console. It can be built and executed |
| on QEMU as follows: |
| |
| make qemu |
| |
| -------------------------------------------------------------------------------- |
| |
| Troubleshooting: |
| |
| Problems caused by out-dated project information can be addressed by |
| issuing one of the following commands then rebuilding the project: |
| |
| make clean # discard results of previous builds |
| # but keep existing configuration info |
| or |
| make pristine # discard results of previous builds |
| # and restore pre-defined configuration info |
| |
