The code I am compiling is the Perlbench benchmark from SPEC-CPU2006. If I
compile the code for an Intel machine using -O2 there is no problem. This
problem only appears when I use the GCC MIPS cross-compiler with the -O2
switch. I also traced through the code and the sequence of these two
instructions should be reversed.
