+Subject: [PATCH] Add support for version 9 .gdb_index
+
+Version 9 .gdb_index adds a new shortcut table. The table itself is
+just two offset_type values (2 * 4 bytes) describing the language of
+the main function expresses as an DW_LANG_ constant and the offset of
+the main function's name in the constant pool.
+
+The offset to the shortcut table in the header is between the symbol
+table and constant pool offsets.
+
+write_gdb_index explicitly copies the function's name into the new
+constant pool (if lang is not zero) because it might not be an offset
+to an existing name of a symbol.
+
+Some extra checks and warnings have been added to let the user know
+when parsing the .gdb_index fails. Add a const char *file argument to
+write_gdb_index for better error reporting.
+
+Add -D_GNU_SOURCE to Makefile CFLAGS_COMMON to use memrchr.
+
+This fixes the gdb-add-index.sh testcase with gdb 15+.
