r249880 installed the result of a strlen in a strinfo if the strinfo wasn't previously a full string. But as Jakub says in the PR comments, we can't just do that in isolation, because there are no vdefs on the call that would invalidate any related strinfos. This patch updates the related strinfos if the adjustment is simple and invalidates them otherwise. As elsewhere, we treat adjustments of the form strlen +/- INTEGER_CST as simple but anything else as too complex. 2017-07-04 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR tree-optimization/81292 * tree-ssa-strlen.c (handle_builtin_strlen): When setting full_string_p, also call adjust_related_strinfos if the adjustment is simple, otherwise invalidate related strinfos. gcc/testsuite/ PR tree-optimization/81292 * gcc.dg/pr81292-1.c: New test. * gcc.dg/pr81292-2.c: Likewise.

This combines the information from previous patches to give a guaranteed alignment for the DR as a whole.

This patch records the base alignment and misalignment in innermost_loop_behavior, to avoid the second-guessing that was previously done in vect_compute_data_ref_alignment. It also makes vect_analyze_data_refs use dr_analyze_innermost, instead of having an almost-copy of the same code. I wasn't sure whether the alignments should be measured in bits (for consistency with most other interfaces) or in bytes (for consistency with DR_ALIGNED_TO, now DR_OFFSET_ALIGNMENT, and with *_ptr_info_alignment). I went for bytes because: - I think in practice most consumers are going to want bytes. E.g. using bytes avoids having to mix TYPE_ALIGN and TYPE_ALIGN_UNIT in vect_compute_data_ref_alignment. - It means that any bit-level paranoia is dealt with when building the innermost_loop_behavior and doesn't get pushed down to consumers. 2017-07-03 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-data-ref.h (innermost_loop_behavior): Add base_alignment and base_misalignment fields.

A later patch adds base alignment information to innermost_loop_behavior. After that, the only remaining piece of alignment information that wasn't immediately obvious was the step alignment. Adding that allows a minor simplification to vect_compute_data_ref_alignment, and also potentially improves the handling of variable strides for outer loop vectorisation. A later patch will also use it to give the alignment of the DR as a whole. 2017-07-03 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-data-ref.h (innermost_loop_behavior): Add a step_alignment field.

This patch renames DR_ALIGNED_TO to DR_OFFSET_ALIGNMENT, to avoid confusion with the upcoming DR_BASE_ALIGNMENT. Nothing needed the value as a tree, and the value is clipped to BIGGEST_ALIGNMENT (maybe it should be MAX_OFILE_ALIGNMENT?) so we might as well use an unsigned int instead. 2017-07-03 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-data-ref.h (innermost_loop_behavior): Replace aligned_to with offset_alignment.

The existing code in arm/bpabi.h was quite fragile and relied on matching specific CPU and/or architecture names. The introduction of the option format for -mcpu and -march broke that in a way that would be non-trivial to fix by updating the list. The hook in that file was always a pain as it required every new CPU being added to be add an update here as well (easy to miss). I've fixed that problem once and for all by adding a new callback into the driver to select the correct BE8 behaviour. This uses features in the ISA capabilities list to select whether or not to use BE8 format during linking. I also noticed that if the user happened to pass both -mbig-endian and -mlittle-endian on the command line then the linker spec rules would get somewhat confused and potentially do the wrong thing. I've fixed that by marking these options as opposites in the option descriptions. The driver will now automatically suppress overridden options leading to the correct desired behavior. Whilst fixing this I noticed a couple of anomolus cases in the existing BE8 support: we were not generating BE8 format for ARMv6 or ARMv7-R targets. While the ARMv6 status was probably deliberate at the time, this is probably not a good idea in the long term as the alternative, BE32, has been deprecated by ARM. After discussion with a couple of colleagues I've decided to change this, but to then add an option to restore the existing behaviour at the user's option. So this patch introduces two new options (opposites) -mbe8 and -mbe32. This is a quiet behavior change, so I'll add a comment to the release notes shortly. * common/config/arm/arm-common.c (arm_be8_option): New function. * config/arm/arm-isa.h (isa_feature): Add new feature bit isa_bit_be8.
