In Dwarf 3 (and Dwarf 2) attributes whose value are offsets into a
section use the form DW_FORM_data4 whilst in Dwarf 4 and later they use the form DW_FORM_sec_offset. This patch updates the places where such attributes are generated to use the appropriate form depending on the Dwarf version. The DIE entries affected have the following tags: DW_AT_stmt_list, DW_AT_ranges, DW_AT_location, DW_AT_GNU_pubnames, DW_AT_GNU_pubtypes, DW_AT_GNU_addr_base, DW_AT_GNU_ranges_base It also adds a hidden command line option "--dwarf-version=<uint>" to llc which allows the version of Dwarf to be generated to override what is specified in the metadata; this makes it possible to update existing tests to check the debugging information generated for both Dwarf 4 (the default) and Dwarf 3 using the same metadata. Patch (slightly modified) by Keith Walker! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195391 91177308-0d34-0410-b5e6-96231b3b80d8
