I'm not sure if these sections are used, but by adding them to libgcc_stripped.a, we can end up with multiple .gnu_debuglink sections in an executable, where the first two unhelpfully point at "libgcc.a". e.g.: $ readelf -SW -x.gnu_debuglink out/target/product/walleye/system/bin/bootstrap/linker64 ... Section Headers: ... [18] .gnu_debuglink PROGBITS 0000000000000000 10f19c 000020 00 0 0 1 ... [22] .gnu_debuglink PROGBITS 0000000000000000 18a2c8 000010 00 0 0 4 ... Hex dump of section '.gnu_debuglink': 0x00000000 6c696267 63632e61 00000000 3d5f65d8 libgcc.a....=_e. 0x00000010 6c696267 63632e61 00000000 3d5f65d8 libgcc.a....=_e. Hex dump of section '.gnu_debuglink': 0x00000000 6c696e6b 65723634 00000000 f85db7ea linker64.....].. Bug: none Test: m libgcc_stripped linker Test: no .gnu_debuglink section in libgcc_stripped.a Test: only one .gnu_debuglink section in system/bin/bootstrap/linker64 Change-Id: I0c47a9acd6d52f5cbc5bfa8b67d072ebb075a242
