Comment at: clang-tidy/modernize/UseNoexceptCheck.cpp:100
+ StringRef ReplacementStr =
+ IsNoThrow ? NoexceptMacro.empty() ? "noexcept" : NoexceptMacro
+ : DtorOrOperatorDel ? "noexcept(false)" : "";
----------------
Did you consider auto-detection approach like in `getFallthroughAttrSpelling`
in tools/clang/lib/Sema/AnalysisBasedWarnings.cpp?
================
Comment at: clang-tidy/modernize/UseNoexceptCheck.cpp:105
+ if (IsNoThrow || NoexceptMacro.empty())
+ FixIt = FixItHint::CreateReplacement(CharSourceRange(Range, true),
+ ReplacementStr);
----------------
I suspect this won't work when the range is not contiguous, e.g. starts in a
macro definition and ends outside of it:
#define T throw
void f() T(a, b) {}
Can you try this test (or construct something similar that will actually break
this code)? In case it doesn't work, `Lexer::makeFileCharRange` is the standard
way to get a contiguous file range corresponding to a source range (if
possible).
================
Comment at: docs/clang-tidy/checks/modernize-use-noexcept.rst:6-8
+The check converts dynamic exception specifications, e.g.,
+``throw()``, ``throw(<exception>[,...])``, or ``throw(...)``, to
+``noexcept``, ``noexcept(false)``, blank, or a user defined macro.
----------------
This description doesn't say why `noexcept` is better.
