Log Message:
-----------
[YARR] `\P{...}` on the right side of a v-mode `&&` or `--` becomes a union
https://bugs.webkit.org/show_bug.cgi?id=321252
Reviewed by Yusuke Suzuki.
appendInverted() adds the complement of its operand directly to the accumulated
matches and ranges without consulting m_setOp, so a pending && or -- turns into
a union.
/[\p{L}&&\P{Lu}]/v.test("A") // true, should be false
/^[\q{ab|c|1}&&\P{L}]$/v.test("ab") // true, should be false
When an intersection or subtraction is pending, materialize the complement into
a
temporary CharacterClass and funnel it through append(), which dispatches on
m_setOp
for both matches and strings. addSortedInverted()'s adjacent-merge branch
targets the
member range vectors, but it cannot fire for the temporary since complement
pieces
are always separated by an element of the operand.
