The tier up check in br_if is only executed conditionally, so it is not allowed to update any cache state. Later code would work with that updated state, even though the corresponding code would not have executed. There was a partial implementation for this by passing in a scratch register for {TierupCheck}, but {TierupCheckOnExit} has the same problem, and needs up to three scratch registers. Until we come up with a better solution, just snapshot the cache state before doing the tier up check, and restore it later. This has some performance cost, but it's an effective fix.

Jakob Kummerow authored
Opportunistically specializing the inlined function's signature based on statically available type information in the caller is currently important for performance, but can make inlining fail if parts of the inlinee relied on the more generic types. This patch addresses that problem by retrying with the original signature in such cases. Long-term, check elimination should be based on typed IR nodes instead.

Port 9ca0bfef Original Commit Message: This adds feedback collection to count the number of executions of call_direct instructions in Liftoff code. The purpose is better inlining decisions in Turbofan, which are enabled by having call count information for all kinds of calls. The new feature is gated on --wasm-speculative-inlining. While direct calls don't need to speculate about their target, the whole feedback collection infrastructure depends on that flag.

Sweeper needs to clean up slots in the OLD_TO_SHARED remembered set as well in the future. Unlike OLD_TO_NEW or OLD_TO_OLD this remembered set will not be reset after a full GC. So we will have to remove from it both during and after a full GC when sweeping. However in the current implementation we still reset this remembered set in a shared GC. This only works because we scan all client heaps during a shared GC anyways to rebuild the remembered set. We will get rid of that when all required write barriers are implemented.

If --liftoff-only is on, we should not execute Turbofan compilation, no matter what the result of Liftoff compilation was. Right now, decoding errors are considered bailouts, which make us fall back to Turbofan and trigger a DCHECK.

Removing slots in the Iterate() method performs an atomic CAS operation on a cell. This is not necessary, we can simply keep slots and drop the whole SlotSet with all buckets after iteration.

Port 9ca0bfef Original Commit Message: This adds feedback collection to count the number of executions of call_direct instructions in Liftoff code. The purpose is better inlining decisions in Turbofan, which are enabled by having call count information for all kinds of calls. The new feature is gated on --wasm-speculative-inlining. While direct calls don't need to speculate about their target, the whole feedback collection infrastructure depends on that flag.

The key idea is that we can now use call count feedback into account consistently for all kinds of calls that support inlining. Bug: v8:12166 Change-Id: I764b8686b6c825a9b24f0032e81f7d1217ef1371 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3574554Reviewed-by:
