Changed paths:
M pp.c
Log Message:
-----------
Replace SvUV_nomg(sv) with SvUVX(sv) in pp_abs.
Under the conditions SvIOK(sv) and SvIsUV(sv), SvUV_nomg(sv) is
equivalent to SvUVX(sv). This change will eliminate unreachable code
and may save a few dozen bytes of code size.

Changed paths:
M pp.c
Log Message:
-----------
Unify SETu() calls in pp_abs.
SETu() is a relatively complex macro and calling it in multiple places
will lead bloating of compiled code. Unifying them with intermediate
variable may save a few hundred bytes.

Changed paths:
M pp.c
Log Message:
-----------
Simplify IV abs operation in pp_abs.
Transforming -iv into "(UV)-(iv + 1) + 1" can avoid signed integer
overflow even if iv was IV_MIN in 2's compelement representation
(as long as iv < 0), so that it makes special treatment for IV_MIN
unnecessary and saves one conditional jump.
