// A union that describes the entries of the vector table. The union is needed
|
|
// since the first entry is the stack pointer and the remainder are function
|
|
// pointers.
|
|
//
|
|
// Normally the vectorTable below would require entries such as:
|
|
// { .topOfStack = x },
|
|
// { .ptrToHandler = y },
|
|
// But since ptrToHandler is defined first in the union, this is the default
|
|
// type which means we don't need to use the full, explicit entry. This makes
|
|
// the vector table easier to read because it's simply a list of the handler
|
|
// functions. topOfStack, though, is the second definition in the union so
|
|
// the full entry must be used in the vectorTable.
