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.

This improves the code generated for float to int64 conversions on x64. Instead of explicitly checking the input for specific values and executing conditional jumps, just convert the integer back to a float and check if this results in the rounded input. The "success value" is then materialized via vmov + and instead of via branches. old: 7 c4e1fb2cd9 vcvttsd2siq rbx,xmm1 c ba01000000 movl rdx,0x1 11 49ba000000000000e0c3 REX.W movq r10,0xc3e0000000000000 1b c441f96efa vmovq xmm15,r10 20 c5792ef9 vucomisd xmm15,xmm1 24 7a08 jpe 0x3599421714ee <+0x2e> 26 7408 jz 0x3599421714f0 <+0x30> 28 4883fb01 REX.W cmpq rbx,0x1 2c 7102 jno 0x3599421714f0 <+0x30> 2e 33d2 xorl rdx,rdx new: 7 c463010bf90b vroundsd xmm15,xmm15,xmm1,0xb d c4e1fb2cd9 vcvttsd2siq rbx,xmm1 12 c4e1832ac3 vcvtqsi2sd xmm0,xmm15,rbx 17 c4c17bc2c700 vcmpss xmm0,xmm0,xmm15, (eq) 1d c4e1f97ec2 vmovq rdx,xmm0 22 83e201 andl rdx,0x1 A follow-up step would be to replace the explicitly materialized success value by a direct jump to the code handling the error case, but that requires more rewrite in TurboFan.

.. for concurrent OSR. There, the challenge is to hit the correct JumpLoop bytecode once compilation completes, since execution has moved on in the meantime. This CL adds a new mechanism to request installation at a specific bytecode offset. We add a new `osr_install_target` field to the BytecodeArray: bitfield struct OSRUrgencyAndInstallTarget extends uint16 { osr_urgency: uint32: 3 bit; osr_install_target: uint32: 13 bit; } // [...] osr_urgency_and_install_target: OSRUrgencyAndInstallTarget; bytecode_age: uint16; // Only 3 bits used. // [...] Note urgency and install target are packed into one 16 bit field, we can thus merge both checks into one comparison within JumpLoop. Note also that these fields are adjacent to the bytecode age; we still reset both OSR state and age with a single (now 32-bit) store. The install target is the lowest 13 bits of the bytecode offset. When set, every reached JumpLoop will check `is this my offset?`, and if yes, jump into runtime to tier up. Drive-by: Rename BaselineAssembler::LoadByteField to LoadWord8Field.

Since the inspector does not longer hold on strongly to Script objects after they were collected by V8, this test was relying on the GC to not collect the scripts too eagerly in case where nothing else holds on to the script. So explicitly adding a global object property assignment here in those cases to ensure that the Script is kept alive.

This is a follow up CL for https://crrev.com/c/3538284. Tests credited to https://crrev.com/c/3468352. - Add unicode filename path test. - Convert ansi encoded filename argv to utf8 encoded on windows. Because the ansi encoded filename argv may lose some information for unicode filename, and we need to use GetCommandLineW to get the actual unicode filename argument. And we convert it to utf8 encoded to be consistent with subsequent processing. - Use REPLACEMENT CHARACTER to replace the characters which cannot be encoded with sys.stdout.encoding in progress.py. This CL should be **reverted** if new unicode filenames cause problems.

Some test variants and fuzzers set their own GC interval, so the flag specified in the regression test causes flag contradictions. The test failure was flaky anyway, so this change is only a slight reduction in reproducability, and the test will still be used as seed for the fuzzers.

Minor MC heap verification requires heap iterability. This however was not directly ensured. Coincidentally, there was an unrelated call to `Heap::Verify` that ensured `Heap::MakeHeapIterable` had been called, so the precondition was met. This call was moved to an earlier point by https://crrev.com/c/3497318 and, because of that, some combination of flags now results in a crash. This CL fixes the issue by directly ensuring heap iterability. It also moves back the call to `Heap::Verify`, so that it takes place inside the GC safepoint.

Embedders can currently specify a callback for OOM errors during Isolate initialization. However, there are cases where an OOM error can be thrown in a context where we don't have access to an Isolate, for example on a task posted to a worker thread. This CL introduces an initialization API to allow the embedder to specify a process-wide OOM callback.

IM::Finalize() was merely finishing marking through the incremental marking in the atomic pause. Avoid the Hurry() call since the marking worklists would anyways be drained with parallel marking.

With kLazy deopts gone, we can remove the stored DeoptimizeKind from Deoptimize nodes and all related spots - all Deoptimize nodes are eager deopts.
