Extended Description

Created an attachment (id=615)
Source code to reproduce fault
The attached produces what looks to me like a 3-partition WL for
rotate() with Build # developer rev 16638, when compiled with:
 sac2c emptycodeblock.sac -b11 >crud
Specifically, I see that the second WL looks like this:
 _pinl_679_result = with {
        (_pinl_731__wlbsc_512_sc_bound <= _pinl_676_iv=[_pinl_692__eat_31] (IDXS:_wlidx_1665__pinl_679_result) < _pinl_540__flat_5)
        {
          _ivesplit_1674 = _wlidx_1665__pinl_679_result;
          _pinl_950__flat_134 = _idx_sel_( _ivesplit_1674, XXX);
        } : _pinl_950__flat_134 ; ,
        (_pinl_548__wlpg_366_zeros <= _pinl_676_iv=[_pinl_692__eat_31] (IDXS:_wlidx_1665__pinl_679_result) < _pinl_740__wlbsc_521_sc_bound)
        {
          _ivesplit_1674 = _wlidx_1665__pinl_679_result;
          _pinl_950__flat_134 = _idx_sel_( _ivesplit_1674, XXX);
        } : _pinl_950__flat_134 ; ,
        (_pinl_740__wlbsc_521_sc_bound <= _pinl_676_iv=[_pinl_692__eat_31] (IDXS:_wlidx_1665__pinl_679_result) < _pinl_540__flat_5)
        {
          _pinl_753__flat_1123 = _sub_SxS_( _pinl_692__eat_31, _pinl_689_count__SSA0_3);
          _ivesplit_1673 = _pinl_753__flat_1123;
          _pinl_678__flat_16 = _idx_sel_( _ivesplit_1673, XXX);
        } : _pinl_678__flat_16 ;
 } :
      modarray( XXX ,IDX(_wlidx_1665__pinl_679_result));
If I'm reading that right, we have these partition bounds:
 r = rotatecount;
 N = array shape
P0:  [ max(0, r) ]  --> [ N]
P1:  [ 0 ]          --> [ r ]
P2:  [ r ]          --> [ N ]
