#757 closed enhancement (fixed)
provide ##core#inline-routines for cheap SRFI-4 vector primitives

Description (last modified by )
XXXvector-length
, XXXvector-ref
and XXXvector-set!
would be much more efficient if routines callable via ##core#inline[_allocate]
would be available for them (just as it currently is for, say, vector-ref
). Since the structure-tag is not available in the C runtime, it has to be explicitly passed, e.g.
C_word C_i_XXXvector_ref(C_word tag, C_word vec, C_word index); C_word C_i_XXXvector_set(C_word tag, C_word vec, C_word index, C_word x); C_word C_i_XXXvector_length(C_word tag, C_word vec);
(need allocating ..._ref
for f64/s32/u32 vector)
Note that the existing C_a_i_f64/S32/u32vector_ref
are incorrectly named and should be C_u_a_i_...
or something similar.

We could also simply make the tags available in a global variable, like we do (or did) for the extended numeric types and the error-hook.

Getting ready for 5.1, moving tickets which won't make it in to 5.2.

Implemented with ea10de3
Note: renaming
C_a_i_XXXvector_ref
and friends will require updating the names inunboxing.scm
