We already have specialized logic for unops and binops, and the generic {BuildSimpleOperator} implementation (based on a signature) was reimplementing these two cases. This CL avoids the switch since we only need to handle exactly two cases, and redirects to the existing methods for implementing them.

In native context independent code we cannot embed the (native context dependent) feedback vector as a constant. Instead, we will load it from the JSFunction once and pass it to all users. This CL makes this change for all unary operators. All other {binary,compare} operators will need similar work in the future.

Until now the breakpointIdToDebuggerBreakpointIds was cleared on page reload. It keeps a map from breakpointIds to debuggerBreakpointIds, with the latter being necessary for removing breakpoints. If a breakpoint is set and we trigger a page reload, the information about that breakpoint will be removed from the map, even if it still exists. If we later want to remove the breakpoint we look into the map, but the meta data is no longer existing. Thus, reloading the page again will lead to hitting the breakpoint, even if we removed it in the front-end. This change keeps the map alive on page reset, so that we still keep track of set breakpoints after a page reload.

evaluate() bypassed CSP for unsafe-eval by default. This is a useful option for debugging clients, but is not always what we want. e.g. in the devtools console we want to match the page's CSP settings to make debugging CSP issues on the page easier.

Make sure that the workers do not start running before the main thread told them so by setting the memory to the first element in the sequence. Otherwise it can happen that the main thread resets the memory after the workers already started doing their updates, which results in a hang (see linked bug).

This is a reland of e0c1a349 The issue was passing SentinelPointer (== +1) through T*. The fix is disabling cfi unrelated cast diagnostic for the bottlenecks (Get()). This means that nullptr is treated the same as kSentinelPointer. The alternative would be a DCHECK that Get() does not return kSentinelPointer and adjusting all Member and Persistent logic that uses Get() to work on void*. This is quite intrusive as it involves Swap(), heterogeneous assignments, comparisons, etc. Original change's description: > cppgc: Properly clear (Weak)Peristent and WeakMember pointers > > The CL addresses two issues with (Weak)Persistent and WeakMember: > 1. (Weak)Persistent pointers are cleared on heap teardown. Before this > CL the pointers would contain stale values which could lead to UAF. > 2.

Prototype f32x4.ceil on ARM for both ARM v7 and ARM v8. ARM v8 has support for vrintp, and for ARM v7 we fallback to runtime. Since ARM v8 uses vrintp, which is the same instruction used for F32 Ceil (scalar), wasm-compiler reuses the Float32Round check, rather than creating new F32x4Round optional operators. Implementation for vrintp (Advanced SIMD version that takes Q registers), assembler, disassembler support. Incomplete for now, but more will be added as we add other rounding modes.
