L1 — Vector Operations
======================

Single-block vector primitives: scaled sums, copies, scaling, dot products,
reductions, norms, and elementwise logic. Pure-SIMT (``glass::block::``, bare
``glass::``) routines are
listed first, followed by the cooperative-groups (``glass::cgrps::``) variants.
Single-warp (``glass::warp::``) variants, where they exist, render inline beside
their block-scoped sibling (e.g. under *reduce*); see :doc:`warp`.

rot / rotg (Givens plane rotation)
----------------------------------

Apply (``rot``, BLAS SROT/DROT: ``x = c*x + s*y``, ``y = c*y - s*x``; block +
``glass::warp::``) and generate (``rotg``, BLAS SROTG/DROTG semantics, the
overflow-safe scaled form; a ``__host__ __device__`` scalar helper).
