* ppc476 plt call stubsAlan Modra2014-04-142-5/+57
| | | | | | | | | | | | Fuss over bctr in call stubs. * elf32-ppc.c (BA): Define (ppc_elf_link_hash_table_create): Correct default_params. (write_glink_stub): Pad small plt call stub with "ba 0" rather than "nop" for ppc476_workaround. (ppc_elf_finish_dynamic_sections): Likewise for branch table and __glink_PLTresolve. Ensure plt call stub at end of page doesn't allow fall-thru prefetch.

* PE32+ binaries that use addresses > 1^32 have a problem in that the linkerNick Clifton2014-04-112-0/+39
| | | | | | | | | | | | | | converts some address expressions into absolute values, but the PE format only stores absolutes as 32-bits. This is a partial solution which attempts to convert such absolute values back to section relative ones instead. It fails for symbols like __image_base and ImageBase__, but it is unclear as to whether these values are ever actually used by applications. PR ld/16821 * peXXigen.c (abs_finder): New function. (_bfd_XXi_swap_sym_out): For absolute symbols with values larger than 1^32 try to convert them into section relative values instead.

* ppc476 icache workaround fix for bctrAlan Modra2014-04-092-19/+54
| | | | | | | | | | | | | | | | | | | | I got the ppc476 workaround wrong. bctr (and bctrl) as the last instruction in a page can hit the icache bug if the preceding mtctr insn is close by, and the destination is in the first few instructions on the next page. This scenario can occur with code generated by gcc to implement switch statements, or in code generated to call by function pointer. To prevent the bctr problem it is also necessary to remove other instructions that otherwise would be safe. bfd/ * elf32-ppc.c (ppc_elf_relocate_section): Remove bctr from list of safe ppc476 insns at end of page.

* Handle VDSO section headers past end of pageAlan Modra2014-04-026-91/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | ELFv2 needs to create plt entries in a non-PIC executable for an address reference to a function defined in a shared object.
