From a943bf960916720e8e2dfdec8d0f2ab843842d3b Mon Sep 17 00:00:00 2001 From: "H. Vetinari" Date: Wed, 1 Nov 2023 18:46:33 +1100 Subject: [PATCH] [lit] Use raw strings for backslash escapes to fix SyntaxWarnings Unless specified as a "raw" string, Python will try to interpret backslashes, which means they don't get passed on correctly to the underlying regex-engine, unless escaped manually (`\\`). Use raw strings in `llvm/test/lit.cfg.py` to avoid a `SyntaxWarning`: ``` llvm/test/lit.cfg.py:275: SyntaxWarning: invalid escape sequence '\d' match = re.search("release (\d+)\.(\d+)", ptxas_out) ``` Other such warning present in 17.0.x were already fixed in 7ed0f5b6de74989c739389770a2d45dc7d58166a. --- llvm/test/lit.cfg.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/llvm/test/lit.cfg.py b/llvm/test/lit.cfg.py index ab245b71cdd16..5f4cff424f073 100644 --- a/llvm/test/lit.cfg.py +++ b/llvm/test/lit.cfg.py @@ -271,7 +271,7 @@ def ptxas_version(ptxas): ptxas_cmd = subprocess.Popen([ptxas, "--version"], stdout=subprocess.PIPE) ptxas_out = ptxas_cmd.stdout.read().decode("ascii") ptxas_cmd.wait() - match = re.search("release (\d+)\.(\d+)", ptxas_out) + match = re.search(r"release (\d+)\.(\d+)", ptxas_out) if match: return (int(match.group(1)), int(match.group(2))) print("couldn't determine ptxas version")
