H A Dindex.rst20 GlobalISel is intended to be a replacement for SelectionDAG and FastISel, to
31 * **Granularity** --- SelectionDAG and FastISel operate on individual basic
36 * **Modularity** --- SelectionDAG and FastISel are radically different and share
74 The initial goal is to replace FastISel on AArch64. The next step will be to
79 SelectionDAG, FastISel, or the other MIR passes. For instance, the types of
85 FastISel Replacement
88 For the initial FastISel replacement, we intend to fallback to SelectionDAG on
91 Currently, compile-time of the fast pipeline is within 1.5x of FastISel.
92 We're optimistic we can get to within 1.1/1.2x, but beating FastISel will be
96 than SelectionDAG+FastISel.
