lc3asm::AsmParser and lc3asm::Rule provides an assembly parser and rules. Parser grammar follows definitions
from Introduction to Computing Systems: From Bits and Gates to C and Beyond. Plus, some features are added:
- UTF-8 string literal support(currently panics if non UTF-8 file is given)
- Backslash escape sequence(
"\\"/"\r"/"\n"/"\t"/"\b"/"\f"/"\u00A9") support in string literal- Note that unicode escape sequence requires exactly four hexadecimal numbers for each character.
- Elegant syntax error reporting(powered by Pest)
- For compatiability issues, decimal literal without
#is accepted for immediate values, but this could be removed in the future.
