Reduced code causing the ICE



I have reduced the code as much as I could to keep the ICE happening. The code

was compiled as follows and the output is also the following. This ICE seems to

be caused when SSE2 is not available.



$LANG=C gcc tigerp2.c -O2 -m32 -march=i486

tigerp2.c: In function 'tiger_block_v2':

tigerp2.c:544:1: internal compiler error: in simplify_subreg, at

simplify-rtx.c:5261
