2014-04-02Handle VDSO section headers past end of pageAlan Modra6-91/+145
When a VDSO gets large enough that it doesn't entirely fit in one page, but not so large that the part described by the program header exceeds one page, then gdb/BFD doesn't read the section headers and symbol table information. This patch cures that by passing the size of the vdso to BFD, and fixes a number of other issues in the BFD code. bfd/ * elfcode.h (bfd_from_remote_memory): Add "size" parameter. Consolidate code handling possible section headers past end of segment. Don't use p_align for page size guess, instead use minpagesize. Take note of ld.so clearing section headers when p_memsz > p_filesz. Handle file header specifying no section headers. Handle zero p_align throughout. Default loadbase to zero. Add comments.

2014-03-27Referencing a function's address on PowerPC64 ELFv2Alan Modra2-43/+75
ELFv2 needs to create plt entries in a non-PIC executable for an address reference to a function defined in a shared object. It's possible that an object file has no features that distinguish it as ELFv1 or ELFv2, eg. an object only containing data. Such files need to be handled like those that are known to be ELFv2. However, this unnecessarily creates plt entries for the analogous ELFv1 case, so arrange to set output abi version earlier, and use the output abi version to further distinguish ambiguous input files. bfd/ * elf64-ppc.c (ppc64_elf_check_relocs): Account for possibly needed plt entries when taking the address of functions for abiversion == 0 (ie. unknown) as well as abiversion == 2. Move opd setup and abiversion checks to.. (ppc64_elf_before_check_relocs): ..here. Renamed from ppc64_elf_process_dot_syms. Set output abiversion from input and input abiversion from output, if either is not set. (ppc64_elf_merge_private_bfd_data): Don't merge flags here.

2014-03-25bfd/elfnn-aarch64.c: Fix calculation of DT_RELASZWill Newton2-2/+8
The current code subtracts the size of the output section containing relplt from RELASZ. In some cases this will be the same output section as the dynamic relocs causing a value of zero to be output.
