Running sgx-asm-pp.py on Python >= 3.12 generates many warnings: sgx-asm-pp.py:64: SyntaxWarning: invalid escape sequence '\s' sgx-asm-pp.py:85: SyntaxWarning: invalid escape sequence '\s' sgx-asm-pp.py:65: SyntaxWarning: invalid escape sequence '\s' sgx-asm-pp.py:86: SyntaxWarning: invalid escape sequence '\s' sgx-asm-pp.py:66: SyntaxWarning: invalid escape sequence '\s' This is a new python change: https://docs.python.org/3/whatsnew/3.12.html#other-language-changes "A backslash-character pair that is not a valid escape sequence now generates a SyntaxWarning, instead of DeprecationWarning. For example, re.compile("\d+\.\d+") now emits a SyntaxWarning ("\d" is an invalid escape sequence, use raw strings for regular expression: re.compile(r"\d+\.\d+")). In a future Python version, SyntaxError will eventually be raised, instead of SyntaxWarning." Given that python intends to turn this into an error in a future release, this should be proactively fixed now. Fortunately the regexes used by sgx-asm-pp don't appear to need to use any genuine backslash escapes, all the backslash usage is for regex characters, so the raw string conversion is simple.
