Lu from comment #2) It is a bug in psABI. It should read as eight \eightbytes. So, let's fix the psABI first and then fix gcc. This PR should be resolved before 4.9 is released.

Lu hjl.tools at gmail dot com changed: What|Removed |Added Status|UNCONFIRMED |NEW Last reconfirmed||2014-02-18 Ever confirmed|0 |1 --- Comment #2 from H.J. Lu hjl.tools at gmail dot com --- (In reply to tocarip.intel from comment #1) From https://github.com/hjl-tools/x86-64-psABI/blob/hjl/avx512/low-level-sys-info. tex \item If the size of an object is larger than four \eightbytes, or it contains unaligned fields, it has class MEMORY struct m512i has size of 64 bytes, which is larger than 8*4=32, so it has class MEMORY and passed on the stack. It looks like everything is according to ABI. It is a bug in psABI. It should read as eight \eightbytes.
