Description Pierre-Olivier Gaillard 2003-08-25 16:44:02 EDT
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):

How reproducible:

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
/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.
Comment 1 Jakub Jelinek 2003-08-29 13:29:30 EDT
No, only gcc 3.3 and later are supposed to handle SSE2 intrinsics fully (gcc 3.2.x should
handle SSE).
