Previously, we supported only SHF_COMPRESSED sections because it's new and it's the ELF standard. But there are object files compressed in the GNU style out there, so we had to support it. Sections compressed in the GNU style start with ".zdebug_" and contain different headers than the ELF standard's one. In this patch, getRawCompressedData is responsible to handle it. A tricky thing about GNU-style compressed sections is that we have to rename them when creating output sections. ".zdebug_" prefix implies the section is compressed. We need to rename ".zdebug_" ".debug" because our output sections are not compressed. We do that in this patch. llvm-svn: 284068
