From: Kyrylo Tkachov <[email protected]>
vcopy_lane deliberately diagnoses both out-of-range lane indices: the
old pragma-builtins checker used & rather than && for exactly that
reason, and neon_shape::check keeps doing so.
r17-2020-g4ff8e6ba9f4e ("aarch64: Port NEON lane get/set intrinsics to
pragma-based framework"), which moved vcopy_lane onto the new shape
framework, dropped the dg-error for the second index in the same commit,
so the test reports an excess error. The diagnostic behaviour is
identical before and after that port, so the deleted directive was
almost certainly a leftover from an intermediate revision of the patch.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/simd/mf8_data_2.c: Restore the dg-error for
the second out-of-range lane index of vcopy_lane_mf8.
