------- Additional Comments From steven at gcc dot gnu dot org 2004-12-19 15:05 ------- With GCC4 (CVS HEAD) I can't compile the test case: t.cc:1: warning: specifying vector types with __attribute__ ((mode)) is deprecated t.cc:1: warning: use __attribute__ ((vector_size)) instead t.cc:1: error: mode 'V2SF' applied to inappropriate type t.cc: In function 'vec2f mul(const vec2f&, const vec2f&)': t.cc:26: error: '__builtin_ia32_pfmul' was not declared in this scope With gcc 3.3.4, I also get: t.cc: In function `vec2f mul(const vec2f&, const vec2f&)': t.cc:28: error: `__builtin_ia32_pfmul' undeclared (first use this function) t.cc:28: error: (Each undeclared identifier is reported only once for each function it appears in.) For the C test case, I get: t.c: In function `mul': t.c:15: error: cast to union type from type not present in union
