It is in between Feb 10, 2015 18:20 UTC (Values: Base: 164.gzip: 1558, 175.vpr: 2392, 176.gcc: 2845, 181.mcf: 3766, 186.crafty: 2926, 197.parser: 1975, 252.eon: 3726, 255.vortex: 3305, 256.bzip2: 2218, 300.twolf: 3257 Peak: , 164.gzip: 1546, 175.vpr: 2397, 176.gcc: 1994, 181.mcf: 3819, 186.crafty: 2737, 197.parser: 1911, 252.eon: 4461, 255.vortex: 4364, 256.bzip2: 2348, 300.twolf: 3265) Feb 10, 2015 09:20 UTC (Values: Base: 164.gzip: 1549, 175.vpr: 2452, 176.gcc: 2734, 181.mcf: 3458, 186.crafty: 2833, 197.parser: 1962, 252.eon: 4083, 255.vortex: 3378, 256.bzip2: 2059, 300.twolf: 3231 Peak: , 164.gzip: 1555, 175.vpr: 2241, 176.gcc: 2800, 181.mcf: 3821, 186.crafty: 2681, 197.parser: 1905, 252.eon: 4415, 255.vortex: 4363, 256.bzip2: 2379, 300.twolf: 3220) So it does not seem to point to inliner changes (fortunately). At Megrez, you should be able to access the diff? Honza
