The gcc.dg/vect/slp-19c.c test FAILs on SPARC (32 and 64-bit):
FAIL: gcc.dg/vect/slp-19c.c scan-tree-dump-times vect "vectorized 2 loops" 1
FAIL: gcc.dg/vect/slp-19c.c scan-tree-dump-times vect "vectorizing stmts using
SLP" 4
The dump shows
gcc.dg/vect/slp-19c.c:31:17: missed: unsupported vect permute { 1 3 }
gcc.dg/vect/slp-19c.c:31:17: missed: permutation not supported, using
elementwise access
gcc.dg/vect/slp-19c.c:31:17: missed: not falling back to elementwise accesses
gcc.dg/vect/slp-19c.c:40:25: missed: not vectorized: relevant stmt not
supported: _16 = in[_15];
gcc.dg/vect/slp-19c.c:31:17: note: unsupported SLP instance starting from:
ia[i_136] = _16;
so the test needs to require vect_perm.
Tested on sparc-sun-solaris2.11 and i386-pc-solaris2.11.
Ok for trunk?
