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). >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
