819f13116e
The original code assumed that the load bias in the program headers would be exactly the same as in eh_frame/eh_frame_hdr/debug_frame. This isn't guaranteed, so add a section bias for use when creating a DwarfSection. In addtion, make the load bias and section bias a signed value. There is no reason that this value needs to be positive, so don't force it to be. Add a new offline test that has a different load bias in eh_frame than in the executable load. Add additional unit tests to verify the load bias values are set properly. Clean up the tests in ElfInterfaceTest, making all tests names follow the same convention. Bug: 141888859 Bug: 142094469 Test: New units and old unit tests pass on host and taimen. Change-Id: Ib878123ab5545f0f315c749cfe0d27b012d873ee
