Unable to use .equ with li pseudo instruction.

[houghtonap]

My environment is using the VS Code extension for venus on Windows 10. I am writing some code and came across an oddity of using .equ with the li pseudo instruction. the code looks like:

         .text
hash:    .globl   hash
         .equ     prime, 0x01000193
         .equ     seed, 0x811C9DC5
         li       a3, prime
         li       a0, seed

This results in the following error in the Venus Terminal:

AssemblerError: test.riscv:36: immediate value out of range: 16777619
li      a3, prime

However, when I remove the .equ and assign the values directly it is successful:

         .text
hash:    .globl   hash
         li       a3, 0x01000193
         li       a0, 0x811C9DC5

Looking at the riscv-asm-manual on github it appears what I'm trying to accomplish is the same as the example in the manual.
