v2.0.19
2f08170
  • A Bend binary starts in 2 ms, not 12: the runtime reserves 8 GiB and
    grows it in place when a program needs more, instead of mapping the whole
    8 TiB address space at every run (#881).
  • A record of records compiles: a datatype past 256 machine words is a heap
    node, the way a recursive type already was, and a constant the compiler
    folds emits once. Seven levels of an eight-field record took 50 s, 19 GB
    and 97 MB of C; it now takes 0.06 s, 122 MB and 82 KB (#843).
  • A match on dense U32 literals compiles to a lookup table, as one on
    Nat already did: 256 cases took 1.46 MB of C and 3.5 GB, and now take
    80 KB and 1.6 GB (#867).
  • The Metal lane computes sin, cos and tan with the GPU's fast trig
    (#887).
  • A - local is erased again: its name is dead in the body, and its value
    is checked dead, so it may spend a variable twice. Since 2.0.16 the mark
    was lost on both counts.
