--- Comment #22 from Jakub Jelinek <jakub at gcc dot gnu.org> --- That is true, but for the common case the relocation table sits in between two parts that need to be used, so in the common case it fseeks over it. I was hoping the relocation table could be last, but that seems very hard because part of the PCH file are stored and read in other functions (in c-family).
