LLVM backend for 6502
relocations (i.e., pieces of data whose addresses are referred to elsewhere in the binary image) and update the references when the section containing the relocations moves. The way this works is that there is a map from section IDs to lists of relocations. Because the relocations are associated with the section containing the data being referred to, they are updated only when the target moves. However, many data references are relative and also depend on the location of the referrer. To solve this problem, I introduced a new data structure, Referrer, which simply contains the section being referred to and the index of the relocation in that section. These referrers are associated with the source containing the reference that needs to be updated, so now regardless of which end of the relocation moves, the relocation will now be updated correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153147 91177308-0d34-0410-b5e6-96231b3b80d8 |
