Subject: SIMD Instruction supported ?
Date: Tue, 7 Mar 2017 12:06:26 +0000	[thread overview]
Message-ID: <BN6PR11MB181169A66A3D97752C9757BFDC2F0@BN6PR11MB1811.namprd11.prod.outlook.com> (raw)

Hi,
I have been trying to exploit SIMD capabilities in a EFI shell application.
I have written a code which calls a procedure with is written in X64 asm.
but my application freezes at the following instruction  
movdqa   xmm0, XMMWORD PTR [rax]

Is SIMD supported in UEFI ?

Platform Details :
Processor :: intel I7, IvyBridge;
P.S i have checked the CPUID and SSE2 XMM are supported. Also the similar code works in windows environment.

Regards 
Amit
