2019-05-21AArch64: Implement choice between Cortex-A53 erratum workarounds. (PR ld/24373)Tamar Christina4-23/+95
The Cortex-A53 erratum currently has two ways it can resolve the erratum when using the flag --fix-cortex-a53-843419: 1) If the address is within the range of an ADR instruction it rewrites the ADRP into an ADR, and those doesn't need the use of a veneer. 2) If the address is not within range, it adds a branch to a veneer which will execute the final bit of the erratum workaround and branch back to the call site. When we do this we always generate the veneers and we always align the size of the text section to 4KB. This is because we only know which workaround we can use after all linking has finished and all addresses are known. This means even though the veneers are not used, we still generate the section and we still change the size of the input section. This is problematic for small memory devices as this would require the user to take about a ~4KB hit in memory even though it's not even used. Since there's no real way to restart the linking process from the final write phase this patch solves the issue by allowing the user more control over which erratum workaround gets used. Concretely this changes the option --fix-cortex-a53-843419 to take optional arguments --fix-cortex-a53-843419[=full|adr|adrp] - full (default): Use both ADRP and ADR workaround. This is equivalent to not specifying any options and is the default behavior before this patch. - adr: Only use the ADR workaround, this will not cause any increase in binary size but linking will fail if the referenced address is out of range of an ADR instruction. - adrp: Use only the ADRP workaround, this will never rewrite your ADRP. In the cases where the user knows how big their binaries are the `adr` option would prevent the unneeded overhead. bfd/ChangeLog: PR ld/24373 * bfd-in.h (enum erratum_84319_opts): New (bfd_elf64_aarch64_set_options, bfd_elf32_aarch64_set_options): Change int to enum erratum_84319_opts. * bfd-in2.h: Regenerate. * elfnn-aarch64.c (struct elf_aarch64_link_hash_table): Change fix_erratum_843419 to use new enum, remove fix_erratum_843419_adr.

2019-05-21Fix PR 24571 - Relaxation does not shorten jmp or call to target at ↵Senthil Kumar Selvaraj2-3/+21
pc-relative range boundary The range check done to transform an absolute call/jump to a pc-relative one is off-by-one, and that causes this shortening optimization to be missed if the branch target is right at the range boundary. In the non-shrinkable case, the range is what is mentioned in the ISA - -4094 bytes in the backward direction, and 4096 bytes in the positive direction. In the shrinkable case, the forward jump range increases by two bytes (deleted because of the shortening from call/jmp to rcall/rjmp), and therefore, the range is -4094 in the reverse, and 4098 in the positive direction. Fix the ranges for !shrinkable and shrinkable cases, and add a test caes to ensure jumps to max forward and backward ranges get relaxed to rjmp.
2019-05-21Fix PR 24564 - link fails for some rcalls/rjmps with wraparoundSenthil Kumar Selvaraj2-1/+7
The current code to compute relative distance in the wrap around case does not handle the edge case of the target (after adjusting for implicit PC increment) being exactly half of the wrap around distance. This patch fixes that and adds a testcase. The range for a forward relative jump call is 4096 bytes ((2 * 2047) + (2 bytes for the implicit PC increment)). If the target of the jump is at a distance of 4098 bytes, it is out of range for a forward jump - however, a backward jump can still reach that address if pmem-wrap-around is 8192. Assume address 0 has rjmp to address 4098. With a wrap around of 8192 and *without* adjusting for the implicit PC increment of 2 bytes, rjmp .-4096 will jump to address 4096 (wrap around at 8192 and decreasing addresses from then on). Adjusting 2 bytes for the implicit PC increment, the actual target is 4098. avr_relative_distance_considering_wrap_around though, does the wrap around only if the passed in distance is less than half of the wrap around distance. In this case, it is exactly equal to half (original distance 4098, adjusted distance of 4096 and wraparound of 8192), and the bypassed wrap around causes the reloc overflow error. Fix by wrapping around even if adjusted distance is equal to half of wrap around distance.

2019-05-04PR24511, nm should not mark symbols in .init_array as "t"Alan Modra3-11/+28
This patch restricts the section names matched in coff_section_type, a function that translates section names to symbol type, and arranges to translate section flags to symbol type before looking at names. The latter change resulted in various test failures due to improper section flags being used in tests, and by the plugin support, so fix that too. The new test fails on many ELF targets that lack .init/fini_array in their scripts. I've just xfailed those. pru-elf oddly defines __init_array_begin rather than __init_array_start.
