38 two register-files for integer (promoted to 64-bit) and float (not promoted!)
39 are used.
40
41 arguments are transfered in a free slot on the corresponding register file.
42 the other register-file will be skipped by one.
43
44 float arguments are either loaded from single or double -
45 a auto-conversion into double and then loaded as double precision
46 turned out to fail for several tests.
47
48 therefore a union for storage of float or double is used instead.
49 a bitmask (mUseDouble) records which type is used and will be
50 interpreted in the call-kernel.
