Herald added a subscriber: rnkovacs.
lebedev.ri added a dependency: D53719:  [clang-tidy] UppercaseLiteralSuffixCheck: bugfix: don't cripple substNonTypeTemplateParmExpr.

The previous, clearly broken output:

  /tmp/test.cpp:13:15: warning: integer literal has suffix 'le', which is not uppercase [hicpp-uppercase-literal-suffix]
  for (auto i : table) {
                ^  ~~
                   LE

I'm so so sad that i'm only now discovering this brokenness.
