From 0e457315f55889878ccbc3e35d4beb04e277733f Mon Sep 17 00:00:00 2001 From: Michael Maitland Date: Wed, 11 Jun 2025 18:19:15 -0400 Subject: [PATCH] [mlir][generate-test-checks] Emit attributes with rest of CHECK lines (#143759) Prior to this patch, generating test checks in place put the ATTR definitions at the very top of the file, above the RUN lines and autogenerated note. All CHECK lines should below the RUN lines and autogenerated note. This change ensures that the attribute definitions are emitted with the rest of the CHECK lines. --------- Co-authored-by: Michael Maitland --- mlir/utils/generate-test-checks.py | 28 +++++++++++++++++++++++----- 1 file changed, 23 insertions(+), 5 deletions(-) diff --git a/mlir/utils/generate-test-checks.py b/mlir/utils/generate-test-checks.py index f77c9688d931..14a790e6d0e6 100755 --- a/mlir/utils/generate-test-checks.py +++ b/mlir/utils/generate-test-checks.py @@ -220,12 +220,19 @@ def process_source_lines(source_lines, note, args): source_segments[-1].append(line + "\n") return source_segments -def process_attribute_definition(line, attribute_namer, output): + +def process_attribute_definition(line, attribute_namer): m = ATTR_DEF_RE.match(line) if m: attribute_name = attribute_namer.generate_name(m.group(1)) - line = '// CHECK: #[[' + attribute_name + ':.+]] =' + line[len(m.group(0)):] + '\n' - output.write(line) + return ( + "// CHECK: #[[" + + attribute_name + + ":.+]] =" + + line[len(m.group(0)) :] + + "\n" + ) + return None def process_attribute_references(line, attribute_namer): @@ -340,6 +347,9 @@ def main(): variable_namer = VariableNamer(args.variable_names) attribute_namer = AttributeNamer(args.attribute_names) + # Store attribute definitions to emit at appropriate scope + pending_attr_defs = [] + # Process lines for input_line in input_lines: if not input_line: @@ -350,8 +360,9 @@ def main(): if input_line.startswith("// -----"): continue - # Check if this is an attribute definition and process it - process_attribute_definition(input_line, attribute_namer, output) + if ATTR_DEF_RE.match(input_line): + pending_attr_defs.append(input_line) + continue # Lines with blocks begin with a ^.
