>Description:
Operations (+ - * /, etc.) on vector modes are not recognized in c++. The following testcase works for C, but not for C++:
typedef float v4sf __attribute__((mode(V4SF)));
void foo()
{
v4sf a, b, c;
a = b + c;
}
bellatrix:~/src/tests$ g++-3.3 -c -msse2 simd2.cpp
simd2.cpp: In function `void foo()':
simd2.cpp:6: error: invalid operands of types `vector float' and `vector
float'
to binary `operator+'
same for gcc 3.4. I suspect this is really rejects-legal, as I see no reason that it shouldnt (but the documentation isnt clear either - vector mode extensions are within the C Extensions part).
