From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030630 Description of problem: Gcc 3.2 is supposed to support Intel SSE2 intrinsics. But when I try to include the xmmintrin.h, I get error messages saying that the sizes are incompatible. NOTE : this is different from the errors you get when you forget to use the -msse2 flag. Version-Release number of selected component (if applicable): gcc-3.2.2 How reproducible: Always Steps to Reproduce: 1. create a simple program including xmmintrin.h 2. compile the program with gcc -msse2 my_prog.c Actual Results: Many errors like the following are displayed. /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include/xmmintrin.h: In function `_mm_add_ss': /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include/xmmintrin.h:90: can't convert between vector values of different size Expected Results: The program should compile and no error should be displayed, since the xmmintrin.h and the gcc binary are both from gcc 3.2.2 (I checked the gcc version with gcc --version). Additional info: Note that the mmintrin.h is correct and works ok with the -msse2 flag set.
No, only gcc 3.3 and later are supposed to handle SSE2 intrinsics fully (gcc 3.2.x should handle SSE).
