// 32-bit Context Frame
//
// This alternate version of the Alpha context structure parallels that
// of MIPS and IX86 in style for the first 64 entries: 32-bit machines
// can operate on the fields, and a value declared as a pointer to an
// array of int's can be used to index into the fields. This makes life
// with windbg and ntsd vastly easier.
//
// There are two parts: the first contains the lower 32-bits of each
// element in the 64-bit definition above. The second part contains
// the upper 32-bits of each 64-bit element above.
//
// The names in the first part are identical to the 64-bit names.
// The second part names are prefixed with "High".
//
// 1st half: at 32 bits each, (containing the low parts of 64-bit values)
// 32 floats, 32 ints, fpcrs, fir, psr, contextflags
// 2nd half: at 32 bits each
// 32 floats, 32 ints, fpcrs, fir, fill
//
// There is no external support for the 32-bit version of the context
// structure. It is only used internally by windbg and ntsd.
//
// This structure must be the same size as the 64-bit version above.
