1928 * Note: you'd expect some comparison/clamp against fetch_elt_max
1930 * There used to be one here but it was incorrect: overflow was
1931 * detected if index > fetch_elt_max - but the correct condition
1932 * would be index >= fetch_elt_max (since this is just size of elts
1933 * buffer / element size).
1934 * Using the correct condition however will cause failures - due to
1935 * vsplit/vcache code which rebases indices. So, as an example, if
1936 * fetch_elt_max is just 1 and fetch_count 2, vsplit cache will
1937 * replace all invalid indices with 0 - which in case of elt_bias
1938 * not being zero will get a different fetch index than the valid
1939 * index 0. So, just rely on vsplit code preventing out-of-bounds
1940 * fetches. This is also why it's safe to do elts fetch even if there
1941 * was no index buffer bound - the real buffer is never seen here, at
1942 * least not if there are index buffer overflows...
1946 * XXX should not have to do this, as scale can be handled
1947 * natively by loads (hits asserts though).
