This patch adds a cache that is valid only for the duration of a call to getKnownBits. With such short lived cache we avoid all the problems of cache invalidation while still getting the benefits of reusing the information we already computed. This cache is useful whenever an instruction occurs more than once in a chain of computation. E.g., v0 = G_ADD v1, v2 v3 = G_ADD v0, v1 Previously we would compute the known bits for: v1, v2, v0, then v1 again and finally v3. With the patch, now we won't have to recompute v1 again. NFC |
