I've never heard this argument before. It does make some sense.
It does have a flaw though. If the code was originally written for IA-32, and
proven to mee
typedef struct {
float re, im;
int dummy;
} complex;
I tried this, and it works.

Just to clar
The IA-64 ABI says that structures of floats are passed/returned decomposed
into floating point registers. They ABI calls them homogeneous floating-point
aggregates, or HFA for short. This also applies to complex types. Thus your
structure
typedef struct {
float re, im;
3 matches
