This is PR34506. Imagine we have 2 sections the same name but different COMDAT groups: .section .foo,"axG",@progbits,bar,comdat .section .foo,"axG",@progbits,zed,comdat When linking relocatable we do not merge SHT_GROUP sections. But still would merge both input sections .foo into single output section .foo. As a result we will have 2 different SHT_GROUPs containing the same section, what is wrong. Patch fixes the issue, preventing merging SHF_GROUP sections with any others. Differential revision: https://reviews.llvm.org/D37574 llvm-svn: 313621
