Now I use DS5 to develop an assembly crypto code, instructions like AESE are used in my code, after assign the CPU = 8-A.64.crypto, the code could be built, but when i debug the code in
8-A.64.crypto, the code could be built, but when i debug the code in
the FVP VE_AEMv8x1, the program crash, do anybody now how to use instructions in ARMv8 ?
Also, Crypto is optional in ARMv8-A (hence it needing a special flag to the build tools). The model can be configured to include the Crypto support or not. If the model is configured to not include the support, the instructions will UNDEF.
Hi, Martin Weidmann
now i only configure CPU = 8-A.64.crypto with armasm, the AES insturction can be built with armasm
8-A.64.crypto with armasm, the AES insturction can be built with armasm
but for armclang, i did't now how to configure the Crypto flag.Do you have any idea?
Thanks for your reply.
