2011-10-04Maintain order of LTO sectionsAndi Kleen4-36/+78
Currently when reading in LTO sections from ld -r files they can get randomly reordered based on hash tables and random IDs. This causes reordering later when the final code is generated and also makes crashes harder to reproduce. This patch maintains explicit lists based on the input order and uses those lists to preserve that order when starting the rest of the LTO passes. This is the first step to working -fno-toplevel-reorder for LTO. But this needs more changes because the LTO partitioner can still reorder. This add two lists: one for the section and another one for the file_decl_datas. This is needed because the sections are walked twice through different data structures. In addition some code becomes slightly cleaner because we don't need to pass state through abstract callbacks anymore, but can just use direct type safe calls. gcc/lto/: 2011-10-02 Andi Kleen <ak@linux.intel.com> * lto-object.c (lto_obj_add_section_data): Add list.
