Roger Kim	f858fba631	[lld][Macho][NFC] Encapsulate priorities map in a priority class ... `config->priorities` has been used to hold the intermediate state during the construction of the order in which sections should be laid out. This is not a good place to hold this state since the intermediate state is not a "configuration" for LLD. It should be encapsulated in a class for building a mapping from section to priority (which I created in this diff as the `PriorityBuilder` class). The same thing is being done for `config->callGraphProfile`. Reviewed By: #lld-macho, int3 Differential Revision: https://reviews.llvm.org/D122156	2022-03-23 13:57:26 -04:00
Leonard Grey	a52b9102d1	[lld-macho] Allow order files and call graph sorting to be used together ... If both an order file and a call graph profile are present, the edges of the call graph which use symbols present in the order file are not used. All of the symbols in the order file will appear at the beginning of the section just as they do currently. In other words, the highest priority derived from the call graph will be below the lowest priority derived from the order file. Practically, this change renames CallGraphSort.{h,cpp} to SectionPriorities.{h,cpp}, and most order file and call graph profile related code is moved into the new file to reduce duplication.
