Jamey Sharp e29d56e430 wasmtime: Remove redundant epoch check on function entry (#8853 ) The epoch interruption implementation caches the current deadline in a register, and avoids reloading that cache until the cached deadline has passed. However, the first epoch check happens immediately after the cache has been populated on function entry, so there's never a reason to reload the cache at that point. It only needs to be reloaded in loops. So this commit eliminates the double-check on function entry. When Cranelift optimizations are enabled, the alias analysis pass correctly detected that this load was redundant, and the egraph pass optimized away the `icmp` as well. However, since we don't do conditional constant propagation, the branch couldn't be optimized away. On x86 this lowered to a redundant `cmp`/`jae` pair of instructions in every function entry, which this commit eliminates. To keep track of what code we're generating for epoch interruptions, I've also added disas tests with a trivial infinite loop.		5 months ago
