| 19 | I guess the tuples are simply sparc-linux and sparc-uclinux. |

| 24 | Don't know, but they have just one toolchain for all targets. |

| 27 | LINUX support for LEON2 and LEON3 is provided through a special |
| 28 | version of the SnapGear Embedded Linux distribution. SnapGear Linux |
| 29 | is a full source package, containing kernel, libraries and |
| 30 | application code for rapid development of embedded Linux systems. The |
| 31 | LEON port of SnapGear supports both MMU and non-MMU LEON |
| 32 | configurations, as well as the optional V8 mul/div instructions and |
| 33 | floating-point unit (FPU). The port include symetric multi-processing |
| 34 | (SMP) support for LEON3 systems with multiple processors. A single |
| 35 | cross-compilation tool-chain is provided which is capable of |
| 36 | compiling the kernel and applications for any configuration. |

| 46 | |
| 47 | So it seems their toolchain could easily be used. |
