[Octave-bug-tracker] [bug #56752] Performance slowdown from version 3.2.4 through to current dev branch

[Rik]

Follow-up Comment #41, bug #56752 (project octave):

@Carlo: I pushed your other changeset here
https://hg.savannah.gnu.org/hgweb/octave/rev/90dfdf0d09ad.

Should the other instances of NoAlias be investigated and replaced as well? 
Using grep in libinterp/ I see


corefcn/cellfun.cc:1944:  NoAlias<Cell> retval;
corefcn/cellfun.cc:2001:  NoAlias<Cell> retval;
corefcn/cellfun.cc:2030:  NoAlias< Array<idx_vector>> ra_idx
corefcn/cellfun.cc:2065:  NoAlias<Cell> retval;
corefcn/cellfun.cc:2480:  NoAlias<Cell> y (x.dims ());
corefcn/data.cc:2725:          NoAlias<Matrix> m (1, ndims);
corefcn/data.cc:7852:  NoAlias< Array<octave_idx_type>> r (rm.dims ());
corefcn/xpow.cc:1195:      NoAlias<NDArray> result (a.dims ());
corefcn/xpow.cc:2504:      NoAlias<FloatNDArray> result (a.dims ());
octave-value/ov-cell.cc:1385:  NoAlias<Cell> c (result_dv);
octave-value/ov-flt-re-mat.cc:741:  NoAlias<FloatNDArray> rr (a.dims ());
octave-value/ov-flt-re-mat.cc:752:          NoAlias<FloatComplexNDArray> rc
(a.dims ());
octave-value/ov-re-mat.cc:868:  NoAlias<NDArray> rr (a.dims ());
octave-value/ov-re-mat.cc:879:          NoAlias<ComplexNDArray> rc (a.dims
());
