- Ibased addressing is removed. The code generated for an Ibased load/store is no better than the code we generate for an Iindexed load/store preceded by a Iconst_symbol instruction that loads the address of the global variable. Plus, we now get opportunities for CSE of the Iconst_symbol.
- Iindexed2 addressing is extended with a constant displacement, to take full advantage of the ofs(%r1, %r2) addressing mode of the processor.
- During selection instruction, make sure that the constant displacement of Iindexed and Iindexed2 is within range (20 bit signed).
