In VisitArrayLiteral(), we stopped creating boilerplates during compilation. This created a bug, because we'd emit an HStoreKeyed with an ElementsKind based on the initial elements kind of the boilerplate. Since boilerplates may transition as part of elements transition feedback, this can lead to incorrect values (storing a smi in a double array).

Instead of dynamically creating semaphore for each page parallel job, we create one semaphore for MarkCompact and reuse it. This patch also removes all instrumentation code that was added to help with investigation.

For now we treat simplified ObjectIsFoo operators as escaping uses when it comes to escape analysis. Eventually we want to handle them in the associated reducer, just like we do with ObjectIsSmi.

This adds support to materialize JSFunction objects from deoptimization information. By now we need to support this because TurboFan's escape analysis can produce virtual (i.e. non-escaping) closures.

port f241a61a (r36360) original commit message: We cannot tier up from interpreted to baseline code when there is an activation of the function on the stack. This significantly regresses the performance of recursive functions since they are unlikely to get tiered up. This CL adds the ability for a function to be marked for baseline compilation when it returns. To do this we patch the InterpreterEntryTrampoline return address to point to InterpreterMarkBaselineOnReturn, which leaves the interpreted frame and recompile the function for baseline. This improves the score of EarlyBoyer by ~8x for Ignition. BUG= Review-Url: https://codereview.chromium.org/1998153002 Cr-Commit-Position: refs/heads/master@{#36396}

In ES2015, the "byteLength" and "byteOffset" properties of DataViews are getters on the prototype, so the previously-used strategy of special-casing them using only the receiver map is invalid. A future CL will need to use the same strategy which will be taken for TypedArray "length", "byteLength", and "byteOffset": adding a prototype chain check.

This patch is a follow up to https://codereview.chromium.org/1972103002/ adding support for the `Operand_R_LSL_I` addressing mode to loads and stores for ARM. Just as the ARM64 implementation, the shift + load/store pattern is only really relevant to the interpreter. For this reason, this patch does not add support for the other addressing modes (`R_LSR_I`, `R_ASR_I` and `R_ROR_I`) as I haven't seen those pattern being generated. Additionally, the optimization is restricted 32 bit loads and stores. kind = BYTECODE_HANDLER name = Star compiler = turbofan Instructions (size = 40) 0x22a5f860 0 e2851001 add r1, r5, #1 0x22a5f864 4 e19610d1 ldrsb r1, [r6, +r1] 0x22a5f868 8 e1a0200b mov r2, fp 0x22a5f86c 12 e7820101 str r0, [r2, +r1, lsl #2] ^^^^^^^^^^^^^^^^^^^^^^^^^ 0x22a5f870 16 e2855002 add r5, r5, #2 0x22a5f874 20 e7d61005 ldrb r1, [r6, +r5] 0x22a5f878 24 e7981101 ldr r1, [r8, +r1, lsl #2] ^^^^^^^^^^^^^^^^^^^^^^^^^ 0x22a5f87c 28 e12fff11 bx r1 BUG= Review-Url: https://codereview.chromium.org/1974263002 Cr-Commit-Position: refs/heads/master@{#36381}
