While it fixes the failures on sparc, it introduces a couple of ICEs on previously working testcases, both i386-pc-solaris2.12 and sparc-sun-solaris2.12, 32 and 64-bit, e.g. FAIL: gcc.dg/vect/bb-slp-24.c (test for excess errors) Excess errors: /vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/vect/bb-slp-24.c:11:6: internal compiler error: tree check: expected class 'expression', have 'exceptional' (ssa_name) in tree_operand_check, at tree.h:3543 0xcad8f3 tree_class_check_failed(tree_node const*, tree_code_class, char const*, int, char const*) /vol/gcc/src/hg/trunk/local/gcc/tree.c:9814 0x104122b expr_check(tree_node*, char const*, int, char const*) /vol/gcc/src/hg/trunk/local/gcc/tree.h:3214 0x104122b tree_operand_check(tree_node*, int, char const*, int, char const*) 0x104122b tree_operand_check(tree_node*, int, char const*, int, char const*) /vol/gcc/src/hg/trunk/local/gcc/tree.h:3543 0x104122b vect_compute_data_ref_alignment(data_reference*) /vol/gcc/src/hg/trunk/local/gcc/tree-vect-data-refs.c:816 0x10423e3 vect_slp_analyze_and_verify_node_alignment /vol/gcc/src/hg/trunk/local/gcc/tree-vect-data-refs.c:2148 0x1042537 vect_slp_analyze_and_verify_instance_alignment(_slp_instance*) /vol/gcc/src/hg/trunk/local/gcc/tree-vect-data-refs.c:2180 0xc805d3 vect_slp_analyze_bb_1 /vol/gcc/src/hg/trunk/local/gcc/tree-vect-slp.c:2677 0xc805d3 vect_slp_bb(basic_block_def*) /vol/gcc/src/hg/trunk/local/gcc/tree-vect-slp.c:2790 0xc82cfb execute /vol/gcc/src/hg/trunk/local/gcc/tree-vectorizer.c:794 Rainer
