// - 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.

// To add a system service simply add the name of the service to the below

|

// follow the name of the serice with a comma and following that the number
|
||
// of bytes of in memory arguments, e.g. CreateObject,40.
