- getSymbolOffset() renamed as getSymbolFileOffset() - getSymbolFileOffset(), getSymbolAddress(), getRelocationAddress() returns same result for ELFObjectFile, MachOObjectFile and COFFObjectFile. - added getRelocationOffset() - fixed MachOObjectFile::getSymbolSize() - fixed MachOObjectFile::getSymbolSection() - fixed MachOObjectFile::getSymbolOffset() for symbols without section data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145408 91177308-0d34-0410-b5e6-96231b3b80d8
