Typically you won't want to copy +these. Instead, you'll want to copy the versions in ../applets and +customize them as needed. + +Pay particular attention to the MIPS calling conventions +you are using. In particular, CFE uses 64-bit register +values. If you compile your program with -mips1 or -mips2, +the 64-bit arguments will be passed as 2 32-bt registers. + +In most cases, CFE only uses the lower 32 bits, since +it can be called from either 32 or 64-bit applications. |
