Summary: x86-64 code is AMD specific (uses 3dnow! instructions
not available on 64-bit intel chips)
Product: Mesa
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: All
Status: NEW
Severity: blocker
Priority: medium
Component: Mesa core
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I got a SIGILL in p4_3d_no_rot_loop () at x86-64/xform4.S:245.
That function (well, all of them in this file) contains prefetchw function.
prefetchw belongs to 3DNow! which is not present in 64-bit Intel chips such as
