2018-05-16PR22458, failure to choose a matching ELF targetAlan Modra1-20/+3
https://sourceware.org/ml/binutils/2013-05/msg00271.html was supposed to banish "file format is ambiguous" errors for ELF. It didn't, because the code supposedly detecting formats that implement match_priority didn't work. That was due to not placing all matching targets into the vector of matching targets. ELF objects should all match the generic ELF target (priority 2), plus one or more machine specific targets (priority 1), and perhaps a single machine specific target with OS/ABI set (priority 0, best match). So the armel object in the testcase actually matches elf32-littlearm, elf32-littlearm-symbian, and elf32-littlearm-vxworks (all priority 1), and elf32-little (priority 2). As the PR reported, elf32-little wasn't seen as matching. Fixing that part of the problem wasn't too difficult but matching the generic ELF target as well as the ARM ELF targets resulted in ARM testsuite failures. These proved to be the annoying reordering of stubs that occurs from time to time due to the stub names containing the section id. Matching another target causes more sections to be created in elf_object_p. If section ids change, stub names change, which results in different hashing and can therefore result in different hash table traversal and stub creation order. That particular problem is fixed by resetting section_id to the initial state before attempting each target match, and taking a snapshot of its value after a successful match.

2018-02-16Remove bfd stub function casts.Alan Modra1-0/+10
This patch defines a bunch of new functions to use in the BFD target structs rather than casting bfd_false or bfd_true and similar stub functions. I've also renamed the stub functions to reflect their parameters and put "error" in the name if they set bfd_error. The latter change is important since there were quite a few uses of bfd_false where setting bfd_error was inappropriate, for example in elf_backend_allow_non_load_phdr and is_target_special_symbol. * libbfd.c (_bfd_bool_bfd_false_error): Rename from bfd_false.

Two organizational changes to the array of additional info kept for sections. 1) Move group info into a per-group allocated struct, in preparation for future changes that need per-group accounting. 2) Expand the array to include output sections, which simplifies sizing and removes the need for a separate output section array. * section.c (section_id): Make file scope.

This implements a work-around for an icache bug on 476 that can cause execution of stale instructions when control falls through from one page to the next. The idea is to prevent such fall-through by replacing the last instruction on a page with a branch to a patch area containing the instruction, then branch to the next page.
