On ELF every section can have a corresponding section symbol. When in an assembly file we have .quad .text the '.text' refers to that symbol. The way we used to handle them is to leave .text an undefined symbol until the very end when the object writer would map them to the actual section symbol. The problem with that is that anything before the end would see an undefined symbol. This could result in bad diagnostics (test/MC/AArch64/label-arithmetic-diags-elf.s), or incorrect results when using the asm streamer (est/MC/Mips/expansion-jal-sym-pic.s). Fixing this will also allow using the section symbol earlier for setting sh_link of SHF_METADATA sections. This patch includes a few hacks to avoid changing our behaviour when handling conflicts between section symbols and other symbols. I reported pr31850 to track that. llvm-svn: 293936 |
