For --- #define FASTCALL __attribute((fastcall)) double FASTCALL f_dii( double p1d, int p2i, int p3i ){ return p1d + (double)p2 i + (double)p3i; } int test_x; int test_y; double test_d1; void caller( void ){ f_dii( test_d1, test_x, test_y ); } --- Gcc 3.4 doesn't pass the first 2 integral parameters in ecx/edx and gcc 4.1 does. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34001
