Kevin Enderby 4f066b6db8 The integrated darwin assembler can hang in an infinite loop (or get an assert ... with a debug build) with this buggy .indirect_symbol directive usage: % cat test.s x: .indirect_symbol _y The assertion is because it is trying to get the symbol index for the symbol _y when it is writing out the indirect symbol table. This line of code in MachObjectWriter::WriteObject() : Write32(Asm.getSymbolData(*it->Symbol).getIndex()); And while there is a symbol _y it does not have any getSymbolData set which is only done in MachObjectWriter::BindIndirectSymbols() for pointer sections or stub sections. I added a check and an error in there to catch this in case something slips through. But to get a better error the parser should detect when a .indirect_symbol directive is used and it is not in a pointer section or stub section. To make that work I moved the handling of the indirect symbol out of the target independent AsmParser code into the DarwinAsmParser code that can check for the proper Mach-O section types. rdar://14825505 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189497 91177308-0d34-0410-b5e6-96231b3b80d8		2013-08-28 17:50:59 +00:00
