84e7813d76e9 gcc-8.2

50 WG vectorization.
84e7813d76e9 gcc-8.2
mir3636

51 - propagate ID variables closer to their uses. This is mainly
84e7813d76e9 gcc-8.2
mir3636

52 to avoid known useless casts, which confuse at least scalar

84e7813d76e9 gcc-8.2
mir3636

54 - use signed long long for storing IDs. Unsigned integers have

55 defined wraparound semantics, which confuse at least scalar

56 evolution analysis, leading to unvectorizable WI loops.
84e7813d76e9 gcc-8.2
mir3636

57 - also refactor some BRIG function generation helpers to brig_function.
84e7813d76e9 gcc-8.2
mir3636
parents: 111

58 - no point in having the wi-loop as a for-loop. It's really

59 a do...while and SCEV can analyze it just fine still.
