------- Comment #18 from bonzini at gnu dot org 2007-11-07 16:26 ------- Created an attachment (id=14498) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=14498&action=view) never say minimal!
So this is a testcase constructed from scratch. 4.3 is 4.5x slower (0.8s vs. 0.18s). Furthermore, if you "#define const", the performance pitfall goes away. For whoever wants to work on this, I would double check with the previous minimal testcase, but this has the same symptoms (no SRA of the Ref instances) and is much much smaller, so it is more suited to go in GCC's testsuite. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33604
