Hello H.J.!
The testscase gcc.target/i386/sse2-vec-5.c you ported from mainline
fails on gcc-4.2 branch because __builtin_ia32_vec_ext_v16qi builtin
does not exist in gcc-4.2. This builtin corresponds to pextrb insn
that was introduced in SSE4 (gcc-4.3).
Also, the definition of __builtin_ia32_vec_ext_v16qi in the mainline
should be enabled only for OPTION_MASK_ISA_SSE4_1, as current
definition is also enabled for SSE2:
def_builtin (OPTION_MASK_ISA_SSE2, "__builtin_ia32_vec_ext_v16qi",
ftype, IX86_BUILTIN_VEC_EXT_V16QI);
I propose that sse2-vec-5.c is removed from the testsuite in gcc-4_2
branch and mainline.
Thanks,
Uros.
