2015-04-01[AArch64] Workaround for Cortex A53 erratum 843419Marcus Shawcroft6-13/+516
Some early revisions of the Cortex-A53 have an erratum (843419). The details of the erratum are quite complex and involve dynamic conditions. For the purposes of the workaround we have simplified the static conditions to an ADRP in the last two instructions of a 4KByte page, followed within four instructions by a load/store dependent on the ADRP. This patch adds support to conservatively scan for and workaround Cortex A53 erratum 843419. There are two different workaround strategies used. The first is to rewrite ADRP instructions which form part of an erratum sequence with an ADR instruction. In situations where the ADR provides insufficient offset the dependent load or store instruction from the sequence is moved to a stub section and branches are inserted from the original sequence to the relocated instruction and back again. Stub section sizes are rounded up to a multiple of 4096 in order to ensure that the act of inserting work around stubs does not create more errata sequences. Workaround stubs are always inserted into the stub section associated with the input section containing the erratum sequence. This ensures that the fully relocated form of the veneered load store instruction is available at the point in time when the stub section is written.

2015-03-27Relax PR 15228 protected visibility restrictionAlan Modra3-6/+17
Allows .dynbss copy of shared library protected visibility variables if they are read-only. To recap: Copying a variable from a shared library into an executable's .dynbss is an old hack invented for non-PIC executables, to avoid the text relocations you'd otherwise need to access a shared library variable. This works with ELF shared libraries because global symbols can be overridden. The trouble is that protected visibility symbols can't be overridden. A shared library will continue to access it's own protected visibility variable while the executable accesses a copy. If either the shared library or the executable updates the value then the copy diverges from the original. This is wrong since there is only one definition of the variable in the application. So I made the linker report an error on attempting to copy protected visibility variables into .dynbss. However, you'll notice the above paragraph contains an "If". An application that does not modify the variable value remains correct even though two copies of the variable exist. The linker can detect this situation if the variable was defined in a read-only section. PR ld/15228 PR ld/18167 * elflink.c (elf_merge_st_other): Add "sec" parameter. Don't set protected_def when symbol section is read-only. Adjust all calls. * elf-bfd.h (struct elf_link_hash_entry): Update protected_def comment.

2015-03-25[AArch64] Implement branch over stub section.Marcus Shawcroft2-1/+25
Ensure that injection of a stub section does not break a link where there is an xpectation that flow of control can pass from one input section to another simply by linking the input sections in series. The solution here is to allow stub sections to be inserted after any input section (existing behaviour), but inject an additional branch at the start of each stub section such that control flow falling into the stub section will branch over the stub section.

2015-03-24[AArch64] Refactor section_group[] representation.Marcus Shawcroft2-12/+8
Change the behaviour of section_group[] such that .stub_sec points to the stub section attached to the indexed section rather than the stub section attached to the link_section pointed to be the index section. This provides a mechanism to get to the stub section following any input section. While still allowing the section grouping mechanism to find the section group stub section associated with an input section by first following the link_sec pointer.
2015-03-24[AArch64] Refactor generation of 835769 workaround stubs.Marcus Shawcroft2-104/+41
This patch recognizes that we only need to perform one scan for the 835769 errata and that this scan can take place before we insert branch stubs. The erratum scan code is relocated and adjusted to create stub entries directly rather than populating an intermediate representation. Since stub entries are created immediately we can drop the adhoc stub size adjustment code and allow the generic stub sizing code to deal with 835769 stub entries. This patch restructures the code but does not change the workaround used to deal with erratum 83679, the exact placement of workaround stubs in the final image may change slightly after this patch due to stubs being created in a different order.
