/*
=====================================
Pointer-width abstraction support
=====================================
AM arguments are always 32-bits wide, but PTR64 platforms need the ability to
send their 64-bit pointers as arguments. We do this by packing pointers into
2 arguments. The macros below support this packing/unpacking so you can write the
calls and handlers once and generate the packing/unpacking code automatically
as required for the platform.
*/
/* AM send call macros (use instead of direct calls to e.g. gex_AM_RequestShort2)
Usage: cnt32 = the number of args needed for AM call on PTR32 platform
cnt64 = the number of args needed for AM call on PTR64 platform
args = parenthesized argument list for AM request/reply call,
with any pointer args wrapped in a PACK() macro
