I get the following error without “iv_map.create (loop->num + 1);”:
"/home/roman/sec_trunk/gcc/gcc/vec.h:1184:39: error: ‘iv_map’ may be
used uninitialized in this function [-Werror=maybe-uninitialized] {
return m_vec ? m_vec->length () : 0; }"

When I'm trying to pass iv_map to vec_safe_grow_cleared I get the
following error:
"/home/roman/sec_trunk/gcc/gcc/graphite-isl-ast-to-gimple.c:596:47:
note: mismatched types ‘vec<T, A, vl_embed>*’ and ‘vec<tree_node*>’
vec_safe_grow_cleared (iv_map, loop->num + 1);"
In case of passing of iv_map*, I get the following error:
"/home/roman/sec_trunk/gcc/gcc/graphite-isl-ast-to-gimple.c:596:47:
error: no matching function for call to
‘vec_safe_grow_cleared(vec<tree_node*>*&, int)’
vec_safe_grow_cleared (iv_map, loop->num + 1);

If we use vec<T, A, vl_embed> as a type for iv_map, we'll have to
rewrite declarations of the following functions, which are working
with vec<tree_node*>:copy_bb_and_scalar_dependences,
graphite_copy_stmts_from_block, rename_uses, chrec_apply_map. We'll
also have to rewrite declarations of iv_map in
graphite-clast-to-gimple.c in this case.
Please correct me, if I am wrong.
