@ -5,6 +5,23 @@ An assembler for the MIPS R4300i architecture, written in Lua.
Not for production. Much of the code and syntax is untested and likely to change.
Even this README is incomplete.
## Integer Precision
**Please note:** some builds of Lua cannot precisely handle integers
larger than 24 bits. This can cause errorenous instructions to be assembled.
LuaJIT and Lua 5.3 shouldn't have this issue by default.
Just to be safe, try running the following script:
```
local precise = 0x1000000 + 1 ~= 0x1000000
if precise then
print("You're all set!")
else
print("You will have a bad time.")
end
```
## Syntax
