I have written a code which calls a procedure with is written in X64 asm. but my application freezes at the following instruction =20 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 c= ode works in windows environment. Regards=20 Amit=20
