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.
