NASM assembler not recognizing ymm16-31 banks

(1/1)

vishal.r:
We are running into a rather strange error with nasm, that it is unable to recognize the ymm banks from 16 to 31.
When compiling, it returns the following error codes - A2071 and error A2006; Undefined reference error.

We are compiling it on Windows with EDK2.
NASM version: 2.14.02

Any suggestions/pointers would be of great help.

Thank you!

zhyhang:
Intel AVX2 only supports 16 256-bit registers, i.e. ymm0-ymm15.
