The current Control::unreachable flag served two things at the same time: It tracked whether the label of that block is reachable (anyone jumps / falls through to there), and it tracked whether that block was ended by an unconditional branch or something similar. It turns out that these two things cannot be tracked with a single boolean per control struct. This CL introduces a Merge::reached flag, which tracks whether a merge point was reached so far. Also, the boolean flag to track unreachability of instructions within a block is extended to track implicitly unreachable instructions. According to the spec, a new block inside of unreachable code must be validated as reachable code again, and also code after a block which never returns has to be validated. It's not needed to generate code for such instructions, however. This new state will be particularly needed for the baseline compiler. A follow-up CL will avoid calling interface methods for unreachable code.

CheckIf is lowered to DeoptimizeIfNot, but there is no deoptimization reason given in the deopt if that check fails (the reason is hardcoded to "no reason"). These deopts are annoying to track down. This patch makes CheckIf an operator with a DeoptimizeReason parameter, which is passed through to the DeoptimizeIfNot when lowered. A couple of checks are converted to give good deoptimize reasons (some new reasons are introduced), and the others are defaulted to kNoReason until someone else finds a use for them.

The use of object literals comes with Object.prototype as the prototype. Some of these were required by the specification, but a change to the specification is proposed in https://github.com/tc39/ecma402/pull/170 to eliminate this. Some of them are unobservable, since Object.prototype is always shadowed, and defineProperty is used rather than ordinary set. However, just to be cautious, all object literals in intl.js except the ones that need it (namely the result of resolvedOptions()) are changed to a null prototype Tests are in the test262 PR https://github.com/tc39/test262/pull/1220 Cq-Include-Trybots: master.tryserver.v8:v8_linux_noi18n_rel_ng Change-Id: I1f684615e60b523441baf31350d752585d8f96d1 Reviewed-on: https://chromium-review.googlesource.com/657839Reviewed-by:

The Scavenger currently requires taking the lock for OLD->NEW processing and can also take another lock for sweeping a different page. Since order of pages during scavenge and sweep is unstable this may result in lock order inversion reports on TSAN when long-running programms are only executed on a single thread. The report is a false positve, hence flag it as suppression until we redesign this particular piece.

The degenerate br_table case should be handled specially only in the graph building consumer. There it is necessary for avoiding the construction of a degenerate Switch node, which would cause a DCHECK error in instruction selection. For other backends, like the baseline compiler, we should handle it as a br_table, because the signature is different to a br. Drive-by: Fix redundant validation.

When an immediate does not fit an add instruction we use a temporary register to hold the value, using movw/movt to encode it. However, in order to remove a use of r9 in TurboFan's code generator, we need to cope with no scratch registers being available. That is to say that the destination and source registers are the same, and `ip` is not available to use. In this case, we can split an add instruction into a sequence of additions: ``` UseScratchRegisterScope temps(...); Register my_scratch = temps.Acquire(); __ add(r0, r0, Operand(0xabcd); // add r0, r0, #0xcd // add r0, r0, #0xab00 ``` As a drive-by fix, make the disassembler test fail if we expected a different number of instructions generated.

The VALIDATE macro should only be used for tests that do not have any side effect, because the side effect will only be executed if validation is active or in debug builds (because the condition is DCHECKed there). The TypeCheckBreak method has side effects since a while, since it inserts unreachable values on the stack. This did not lead to failures so far, since we only have validating users of the WasmFullDecoder. This will change once we have general lazy compilation of wasm modules, e.g. for tier-up.
