Subject: stdlib: Implement C2Y uabs, ulabs, ullabs and uimaxabs
X-Git-Tag: glibc-2.42~322
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5b132ec2b7712dbc055838b3b538b83ad1196414;p=thirdparty%2Fglibc.git

stdlib: Implement C2Y uabs, ulabs, ullabs and uimaxabs

C2Y adds unsigned versions of the abs functions (see C2Y draft N3467 and
proposal N3349).

Tested for x86_64.

 These functions return the absolute value of @var{number}.
 
 Most computers use a two's complement integer representation, in which
 the absolute value of @code{INT_MIN} (the smallest possible @code{int})
 cannot be represented; thus, @w{@code{abs (INT_MIN)}} is not defined.
+Using @code{uabs} avoids this.
 
 @code{llabs} and @code{imaxdiv} are new to @w{ISO C99}.
