> Hi, > > This patch introduces `JitCompiler::isConstantExpression` which can be used > to statically determine whether an expression has been constant-folded by the > Jit compiler, leading to more constant-folding opportunities. For example, it > can be used in `MemorySessionImpl::checkValidStateRaw` to eliminate the > lifetime check on global sessions without imposing additional branches on > other non-global sessions. This is inspired by `std::is_constant_evaluated` > in C++. > > Please kindly give your opinion as well as your reviews, thanks very much.
