The only difference from r219829 is using getOrCreateSectionSymbol(*ELFSec) instead of GetOrCreateSymbol(ELFSec->getSectionName()) in ELFObjectWriter which causes us to use the correct section symbol even if we have multiple sections with the same name. Original messages: r219829: Correctly handle references to section symbols. When processing assembly like .long .text we were creating a new undefined symbol .text. GAS on the other hand would handle that as a reference to the .text section. This patch implements that by creating the section symbols earlier so that they are visible during asm parsing. The patch also updates llvm-readobj to print the symbol number in the relocation dump so that the test can differentiate between two sections with the same name. r219835: Allow forward references to section symbols. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220021 91177308-0d34-0410-b5e6-96231b3b80d8
