[PATCH] D67504: [ELF] Make SHF_MERGE merging aware of output sections

[Fangrui Song via Phabricator via llvm-commits]

MaskRay updated this revision to Diff 219936.
MaskRay added a comment.

Delete unrelated InputSectionIterator (I tried changing `InputSectionDescription::sections` from an InputSection* vector to InputSectionBase* vector, but the result is not clean - many subsequent passes assume the elements of `sections` are InputSections. The size of OutputSection is not a big concern, so I added another field instead)

Fix a comment.

Add `llvm::erase_if(inputSections, [](InputSectionBase *s) { return isa<MergeInputSection>(s); });` to fix an assetion failure
