From 266da65e9156d93e1126e185259a4aae68188d0e Mon Sep 17 00:00:00 2001 From: Dave Martin Date: Thu, 1 Mar 2018 17:44:06 +0000 Subject: signal: Add FPE_FLTUNK si_code for undiagnosable fp exceptions Some architectures cannot always report accurately what kind of floating-point exception triggered a floating-point exception trap. This can occur with fp exceptions occurring on lanes in a vector instruction on arm64 for example. Rather than have every architecture come up with its own way of describing such a condition, this patch adds a common FPE_FLTUNK si_code value to report that an fp exception caused a trap but we cannot be certain which kind of fp exception it was.
