// alpha version
|

|
|
// - 6 argument registers for alpha
|
|||
|
|
// - size of allocation for each table entry address = 64 bits
|
|||
|
|
// (this was necessary with BL3 of the compiler, it may no
|
|||
|
|
// longer be the case but this shouldn't hurt, the system
|
|||
|
|
// service exception code will load long anyway)

// The first line of this file was "6 8" which the new gensrv used
|
|||
|
|
// to set the number of in-register arguments (6) and the size of a
|
|||
|
|
// register (8).
|
|||
|
|
//
|
|||
|
|
// Now instead, the ARGTBL_ENTRY macro itself converts i386/Mips 4
|
|||
|
|
// byte units into Alpha 8 byte units. This way, if an old version
|
|||
|
|
// of gensrv is used, we still get the proper byte counts for Alpha.
