--- Comment #2 from Steve Ellcey <sje at gcc dot gnu.org> --- Created attachment 31365 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=31365&action=edit runnnable performance test case Here is a runnable test case. You may need to increase the loop counts depending on the speed of your machine. On the MIPS system I used a 4.7.3 GCC took 36.127 seconds and a 4.8.1 GCC took 38.435 seconds (Little endian, -O2, static linking).
