%% Filename : hipe_rtl_arith_32.erl
%% Module : hipe_rtl_arith_32
%% Purpose : To implement 32-bit RTL-arithmetic
%% Notes : The arithmetic works on 32-bit signed integers.
%% The implementation is taken from the implementation
%% of arithmetic on SPARC.
%% XXX: This code is seldom used, and hence also
%% seldom tested.
%% Look here for strange bugs appearing when
%% turning on rtl_prop.
%%
%% History : * 2002-10-23 Erik Stenman ([email protected]): Created.
