[PATCH] D72841: [RFC] Add support for pragma float_control, to control precision and exception behavior at the source level

[Serge Pavlov via Phabricator via cfe-commits]

sepavloff added a comment.

You could check the scope where the pragma appears is the same way as `pragma clang fp` does. The code

  case tok::annot_pragma_fp:
    ProhibitAttributes(Attrs);
    Diag(Tok, diag::err_pragma_fp_scope);
    ConsumeAnnotationToken();
    return StmtError();

is put into `Parser::ParseStatementOrDeclarationAfterAttributes` and it produces errors on misplaced pragma. Probably the same way may work for you.
