We need to check whether advancing the iterator moved us beyong the end of the bitmap. This has not been flushed out as our inlined bitmap is still in valid memory. In practice this is not a problem because the value is never used as we are at the end of the bitmap. Asan rightfully complains when using an external bitmap though.

The BitcastWordToTagged operator is used for bump pointer allocation to construct the actual HeapObject pointer. The input to this operator is a naked pointer (derived from the allocation top). If this input value is live across an allocation, then the resulting tagged pointer is invalid because the GC might have scavenged new space in the meantime. That means we must not allow Node splitting (in the Scheduler) for these instructions, as that could extend the live range of the naked pointer input across arbitrary code. As such, this operator must not be marked as pure. R=jarin@chromium.org BUG=v8:6059 Review-Url: https://codereview.chromium.org/2739093002 Cr-Commit-Position: refs/heads/master@{#43683}

Port e82b7ccd Original Commit Message: I originally needed this for the initialization of a constexpr array in the wasm lazy compile builtin, but since it's a bigger change, I now split it off as this separate CL. The style guide recommends constexpr over const. I thus apply the constexprificaton over all headers that I touched anyway. I also remove the ARM64_DEFINE_REG_STATICS hack. It was introduced when merging in arm64 support more than three years ago, and I don't see the purpose for this. Also, some #defines can now be constexpr definitions, which was not possible before according to the comment.

This introduces a new truncation bit for truncation of minus-zero to zero. At the moment it is only used to handle the limit cases of deopt, such as the one in the Google maps workload (see simplified version below), where the -q (which is desugared to q * -1.0) currently deoptimizes because the result would produce minus zero. To handle this situation, we exploit the knowledge that righthand side of + cannot be -0, so even if lefthand side was -0, the result would still be 0 (so the + operation cannot distinguish between left hand side 0 and -0). function f(q) { q -= 4; return (-q) + q; } f(10); f(10); %OptimizeFunctionOnNextCall(f); f(4); Review-Url: https://codereview.chromium.org/2734253002 Cr-Commit-Position: refs/heads/master@{#43661} -

For nodes NumberMin(lhs, rhs) NumberMax(lhs, rhs) we might have feedback types for lhs and rhs that would allow us to generate unsigned32 or signed32 versions of this operator, which is way more efficient that going to the full Float64Min/Float64Max operator. However we cannot promise word32 truncations in this case, since we based this decision on the feedback types. This allows us to generate better code for Math.min and Math.max when one of the inputs is a speculative number operator that provides better typing during representation selection. We've seen such code in the hottest function on Google Maps for example.
