Hi, I'm currently working on reproducibility for Fedora packages and I'm hitting an issue with lto/annobin. Filenames generated with https://github.com/gcc-mirror/gcc/blob/master/gcc/lto-wrapper.c#L1769 makes annobin gcc plugin injecting in the default case random pattern into elf (https://sourceware.org/git/?p=annobin.git;a=blob;f=gcc-plugin/annobin.cc;h=613379bb8d351596d7c73c723963b51df42f4971;hb=HEAD#l198). For example, a readelf symbolds of a built Fedora packages could have: 35: 0000000000002af0 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o 36: 00000000000047a1 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o_end 37: 0000000000002a30 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o.hot 38: 0000000000002a30 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o_end.hot 39: 0000000000002a30 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o.unlikely 40: 0000000000002a30 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o_end.unlikely 41: 0000000000002a30 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o.startup 42: 0000000000002a30 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o_end.startup 43: 0000000000002a30 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o.exit 44: 0000000000002a30 0 NOTYPE LOCAL HIDDEN 13 .annobin_dummyqbs_drv.so.MDkv6z.ltrans0.o_end.exit I've succeeded to brutally replace the input filenames by a constant pattern to make the build reproducible. Do you have any idea what would be the best strategy to fix that? lto-wrapper or in the annobin plugin? Best regards, Frédéric
