Thanks @erichkeane for response.
@MyDeveloperDay, Our internal Coverity link won't work without login.
This is what Coverity was complaining about.
Big parameter passed by value
Copying large values is inefficient, consider passing by reference; Low,
medium, and high size thresholds for detection can be adjusted.
1. In clang::format::internal::reformat(clang::format::FormatStyle const
&, llvm::StringRef, llvm::ArrayRef<clang::tooling::Range>, unsigned int,
unsigned int, unsigned int, llvm::StringRef,
clang::format::FormattingAttemptStatus
*)::[lambda(clang::format::Environment const &) (instance 5)]::operator
()(clang::format::Environment const &): A very large function call parameter
exceeding the high threshold is passed by value. (CWE-398)
if (Style.RemoveSemicolon) {
3499 FormatStyle S = Expanded;
3500 S.RemoveSemicolon = true;
pass_by_value: Capturing variable S of type clang::format::FormatStyle (size
572 bytes) by value, which exceeds the high threshold of 512 bytes.
3501 Passes.emplace_back([&, S](const Environment &Env) {
3502 return SemiRemover(Env, S).process(/*SkipAnnotation=*/true);
3503 });
3504 }
2. In clang::format::internal::reformat(clang::format::FormatStyle const

()(clang::format::Environment const &): A very large function call parameter
exceeding the high threshold is passed by value. (CWE-398)
if (Style.RemoveBracesLLVM) {
3491 FormatStyle S = Expanded;
3492 S.RemoveBracesLLVM = true;
pass_by_value: Capturing variable S of type clang::format::FormatStyle (size
572 bytes) by value, which exceeds the high threshold of 512 bytes.
