The testcase FAILs on Solaris/SPARC:
FAIL: gcc.dg/vect/bb-slp-35.c -flto -ffat-lto-objects scan-tree-dump slp2
"basic block vectorized"
FAIL: gcc.dg/vect/bb-slp-35.c scan-tree-dump slp2 "basic block vectorized"
The dump
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/vect/bb-slp-35.c:6:11: note:
not vectorized: unsupported unaligned store.*p_6(D)
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/vect/bb-slp-35.c:6:11: note:
not vectorized: unsupported alignment in basic block.
suggests that the following adjustment is needed. Tested on
sparc-sun-solaris2.11 on x86_64-unknown-linux-gnu.
Ok for mainline?
