[AArch64] Rename cmp_result iterator
The comparison results provided by the V_cmp_result/v_cmp_result attribute were simply the corresponding integer vector. We'd also like to have easy access to the integer vector for SVE, but using "cmp_result" would be confusing because SVE comparisons return predicates instead of vectors. This patch therefore renames the attributes to the more general V_INT_EQUIV/v_int_equiv instead. As to the capitalisation: there are already many iterators that use all lowercase vs. all uppercase names to distinguish all lowercase vs. all uppercase expansions (e.g. fcvt_target and FCVT_TARGET). It's also the convention used for the built-in mode/MODE/code/CODE/etc. attributes. IMO those names are easier to read at a glance, rather than relying on a single letter's difference. 2017-08-22 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * config/aarch64/iterators.md (V_cmp_result): Rename to...
