I backed out the original patch #33, and replaced it with the one you sent me, and it does allow dealII to be built. I rebuilt all 30 benchmarks in Spec 2006, and now they all build. I ran a full spec 2006 suite on a little endian power8 that we normally use to run Spec. Note, I use different options to build spec that the people that do the official runs, so the results are in no way official results. I'm only providing the differences, and not the spec numbers. Generally, I consider differences between runs that were less than 2% to be in the noise level. There were only two benchmarks that had differences more than 2%: * 456.hmmer had an 8% regression * 434.zeusmp had a 3% speedup. In terms of smaller differences, the following had 1% differences: * 410.bwaves had a 1% regression * 459.GemsFDTD had a 1% regression * 437.leslie3d had a 1% speedup * 453.povray had a 1.6% speedup -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meiss...@linux.vnet.ibm.com, phone: +1 (978) 899-4797
