+Subject: [PATCH] debug/101473 - apply debug prefix maps before checksumming DIEs
+
+The following makes sure to apply the debug prefix maps to filenames
+before checksumming DIEs to create the global symbol for the CU DIE
+used by LTO to link the late debug to the early debug. This avoids
+binary differences (in said symbol) when compiling with toolchains
+installed under a different path and that compensated with appropriate
+-fdebug-prefix-map options.
+
+The easiest and most scalable way is to record both the unmapped
+and the remapped filename in the dwarf_file_data so the remapping
+process takes place at a single point and only once (otherwise it
+creates GC garbage at each point doing that).

+
+The upstream patch was modified to compensate for the definition of
+"struct dwarf_file_data" being in dwarf2out.c rather than dwarf2out.h in
+this version of gcc.
