States

States64

Model of states for RV64I.

Along with the model of states, we define some operations on the states.

Subtopics

Write64-xreg: Write a 64-bit integer to an x register.
Write64-xreg-32: Write an integer to the low 32 bits of an x register, sign-extending it to the high 32 bits of the register.
Write64-mem-ubyte64-lendian: Write an unsigned 64-bit little endian integer to memory.
Write64-mem-ubyte16-lendian: Write an unsigned 16-bit little endian integer to memory.
