We left x86_64
unchanged (it uses MOV
instructions).
We implemented constant pools for aarch64
in an incremental way. We allocate code memory in 1MB chunks. In each chunk we assemble code forwards and collect constants backwards. When there is too little free space between the two, we allocate the next chunk and assemble a branch to it. This incremental scheme avoided any changes to Lower::action()
