Another fallout due to the using VCE more patch:
#define vector __attribute__((vector_size(16) ))
struct struct1 {
union { float a[3]; } vmx;
struct struct2 {
struct2(const struct2& r) {}
} w;
} __attribute__((aligned(16)));
struct struct3 {
vector float vmx;
operator const struct1& () const{
return *reinterpret_cast<const struct1*>(this);
}
};
struct3 func3( struct3 V1);
struct3 func2( void );
void func1( ) {
struct1 vVec = func2() ;
func3 ( (struct3&)vVec );
}
--- CUT ---
This time you need to compile with -O2 -maltivec and it does not happen under
x86 for some reason.
