* [AArch64] Workaround for Cortex A53 erratum 843419Marcus Shawcroft2015-04-016-1/+179
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Start of relro segment adjustmentAlan Modra2015-04-014-17/+33
| | | | | | | | | | | | | | | | | | | | | | Adjusting the start of the relro segment in order to make it end exactly on a page boundary runs into difficulties when sections in the relro segment are aligned; Adjusting the start by (next_page - end) sometimes results in more than that adjustment occurring at the end, overrunning the page boundary. So when that occurs we try a new lower start position by masking the adjusted start with the maximum section alignment. However, we didn't consider that this masked start address may in fact be before the initial relro base, which is silly since that can only increase padding at the relro end. I've also moved some calculations closer to where they are used, and comments closer to the relevant statements. * ldlang.c (lang_size_sections): When alignment of sections results in relro base adjustment being too large, don't go lower than the initial value. * ldexp.c (fold_binary <DATA_SEGMENT_RELRO_END>): Comment. * scripttempl/elf.sc (DATA_SEGMENT_ALIGN): Omit SEGMENT_SIZE alignment when SEGMENT_SIZE is the same as MAXPAGESIZE.

* Properly place the NULL STT_FILE symbol revistitedAlan Modra2015-02-1829-52/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was having a little closer look at what is going on here and noticed that HJ unconditionally emits a NULL STT_FILE symbol before emitting forced local symbols. That means we really don't need a second pass over forced local symbols. The only reason for two passes is when some forced local symbol can be emitted before the NULL STT_FILE. So I set about removing the second pass, updating the testsuite all over again. It's also unnecessary to emit the NULL STT_FILE when no previous file symbol has been emitted. bfd/ PR ld/17975 * elflink.c (struct elf_outext_info): Remove need_second_pass and second_pass. (elf_link_output_extsym): Delete code handling second forced local pass. Move code emitting NULL STT_FILE symbol later, so that it can be omitted if forced local is stripped.
