Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jan.kratochvil at redhat dot com, | |palves at gcc dot gnu.org --- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- So, I guess we need help on how does gdb determine the initial file when loading a program (i.e. when you run gdb ./program , when you get prompt, what file is l showing or b <number> putting breakpoint in). With the new LTO debug info, we have .file "<artificial>" with both -f{,no-}reorder-blocks-and-partition. The CU that imports the unit with main has: .long .LASF1 # DW_AT_name: "<artificial>" .long .LASF2 # DW_AT_comp_dir: "/usr/src/gcc/obj/gcc" too. Pedro/Jan, could you try this (I can provide binaries off-line) and say where gdb sees the difference and why doesn't it make the file containing main the default?
