MC: correct DWARF header for PE/COFF assembly input The header contains an offset to the DWARF abbreviations for the CU. The offset must be section relative for COFF and absolute for others. The non-assembly code path for the DWARF header generation already had the correct emission for the headers. This corrects just the assembly path. Due to the invalid relocation, processing of the debug information would halt previously on the first assembly input as the associated abbreviations would be out of range as they would have the location increased by image base and the section offset. This address PR20332. llvm-svn: 213275

MC: correct DWARF header for PE/COFF assembly input The header contains an offset to the DWARF line table for the CU. The offset must be section relative for COFF and absolute for others. The non-assembly code path for the DWARF header generation already has the correct emission for the headers. This corrects the assembly input path. This was identified by BFD objecting to the LLVM generated DWARF information. llvm-svn: 217222

MC: correct DWARF line info for PE/COFF DWARF address ranges contain a reference to the debug_info section. This offset is an absolute relocation except on non-PE/COFF targets where it is section relative. We would emit this incorrectly, and trying to map the debug info from the address would fail. llvm-svn: 217317
