/* regression test: a hex literal with the high bit of a 64-bit word
 * set (16 hex digits starting 8-f) used to crash the compiler outright
 * (perl's own "non-portable" advisory escalated to fatal under
 * `use warnings FATAL`, in both jtype3's int_value and jemit8's
 * needs_abs), and separately, casting an i64-typed literal to u64 was
 * wrongly rejected as if u64 were narrower than i64 (it isn't -- same
 * width, non-negative source, never a truncation). */
