4 | Subject: [PATCH] debug/101473 - apply debug prefix maps before checksumming DIEs | ||
5 | |||
6 | The following makes sure to apply the debug prefix maps to filenames | ||
7 | before checksumming DIEs to create the global symbol for the CU DIE | ||
8 | used by LTO to link the late debug to the early debug. This avoids | ||
9 | binary differences (in said symbol) when compiling with toolchains | ||
10 | installed under a different path and that compensated with appropriate | ||
11 | -fdebug-prefix-map options. | ||
12 | |||
13 | The easiest and most scalable way is to record both the unmapped | ||
14 | and the remapped filename in the dwarf_file_data so the remapping | ||
15 | process takes place at a single point and only once (otherwise it | ||
16 | creates GC garbage at each point doing that). | ||

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