Date: Tue, 8 Nov 2011 23:04:02 +0400 From: Solar Designer <solar@...nwall.com> To: john-dev@...ts.openwall.com Subject: floating-point math after MMX magnum - I expect that 0022-j7-Fix-for-huge-figures-in-MPI-sum-avg-cps-64-bit-ov.patch and 0027-j7-Optionally-output-number-of-candidates-tried.patch would cause misreporting when running MMX-using builds (and formats for which MMX specifically is actually used) on certain CPUs. I previously observed this on Pentium 3, for which there's now a workaround in -jumbo's status.c: status_get_ETA() and status_get_totalETA(), but not in other functions. Basically, we only issue the EMMS instruction right before doing floating-point math. Is this something you can test for (on a P3) and patch now or should I? Thanks, Alexander
