Since this is `const char*` to `const LChar*` cast, bitwise_cast is necessary. (LChar is uint8_t). >> JSTests/stress/regexp-syntax-error-invalid-flags.js:18 >> + return /Hello/cocoa; > > I vote for adding a few more invalid regrex tests The other invalid RegExp becomes early (parser phase) syntax error. We have relaxed rule for invalid flags, which raise runtime errors. 1383955 4 ysuzuki 2017-12-20 17:58:34 -0800 Committed r226209: <https://trac.webkit.org/changeset/226209> 1383956 5
