Hmm, you're right
On Mon, Feb 12, 2018 at 8:39 PM, Joshua Watt <jpewhacker at gmail.com> wrote:
The code to extract the integer number of parallel build threads and
construct a new argument from them has started to be copied in multiple
locations, so create two new helper utilities to aid recipes.
The first helper (parallel_make()) extracts the integer number of
parallel build threads from PARALLEL_MAKE. The second
(parallel_make_argument()) does the same and then puts the result back
into a format string, optionally clamping it to some maximum value.
Additionally, rework the oe-core recipes that were manually doing this
to use the new helper utilities.
