[PATCH] stdlib: Implement C2Y uabs, ulabs, ullabs and uimaxabs
Lenard Mollenkopf
glibc@lenardmollenkopf.de
Thu Mar 6 19:24:39 GMT 2025
C2Y adds unsigned versions of the abs functions (see C2Y draft N3467 and
proposal N3349).
Tested for x86_64.

the absolute value of @code{INT_MIN} (the smallest possible @code{int})
cannot be represented; thus, @w{@code{abs (INT_MIN)}} is not defined.
