--- Comment #1 from Uroš Bizjak <ubizjak at gmail dot com> ---
This looks like a consequence of following i386-builtin-types.c comment:

# ??? Logically this should be intQI_type_node, but that maps to "signed char"
# which is a different type than "char" even if "char" is signed.  This must
# match the usage in emmintrin.h and changing this would change name mangling
# and so is not advisable.
DEF_PRIMITIVE_TYPE (QI, char_type_node)

Like Andreas, this works for me with latest 4.9 and trunk.  I see the 3.4.15
symbols in both cases.

Proposed patch

This patch employs Uros's suggestion everywhere to make
sse-13.c pass w/ `-funsigned-char' option added.

We also should make all mask arguments in built-in decls
of unsigned type, but this can wait for stage1.
