A few fixes for the C++17 parallel algorithms which should have been included in other papers slipped through the cracks.
This paper addresses NB comments US 161, US 162 and US 184.
2. Proposed Changes
The following changes are relative to the latest working paper as of 03-02-2017 ([N4640]) with the changes from [P0467r2] and [P0574r1] applied.
The � character is used to denote a placeholder section number.
2.1. Add Type Requirements From [P0574r1] To [P0452r1]'s New
Modify the requirements for the new signatures of
transform_reduce added by [P0452r1] to 26.8.4 [transform.reduce]:
binary_op2shall invalidate subranges, or modify elements in the ranges
[first2, first2 + (last1 - first1).
Direction to the Editor: Add a footnote to the use of fully-closed ranges in the change above that says .
2.2. Forbid The
result == first Case For Parallel
Modify the remark in 26.8.11 paragraph 3 regarding whether the input and output
ranges given to
adjacent_difference can overlap:
resultmay be equal to
