        This is skipped only on arm memory limited platforms. Until recently
        it was not a problem on MIPS as the butterfly was not initialized. But
        since r227435, the butterfly is initialized in that test and therefore
        memory is allocated, and the test typically takes around 512M, which
        means it generally gets OOM-killed on the MIPS buildbot.

        Relanding after https://bugs.webkit.org/show_bug.cgi?id=178834.

        Add some simple test that computes factorial in several ways, and other trivial computations.
        They all tests the case where foo calls bar (in an inlineable way) that then does a tail call.
        Depending on the nature of both calls, it is possible or not to turn the tail call into a loop.
        I have no clear way of checking that the call was indeed transformed, but I can check that the code computes the right result
        (which it doesn't if that tail call is transformed into a loop in the unsound cases).

        Debug builds are just slow, and these tests do a lot.  They pass when I run them
        locally on my MacBook Pro.  So, I'm bumping their timing multiplier to 2.0x as
        a speculative fix for the bots that are seeing these fail.

        Instead of throwing if any unary operator precedes new.target, only
        throw if the unary operator updates the reference.

        The following become legal in JSC:

        ```
        !new.target
        ~new.target
        typeof new.target
        delete new.target
        void new.target

        [Linux] JSTests/wasm/stress/oom.js should not run on Linux
        https://bugs.webkit.org/show_bug.cgi?id=175100

        Reviewed by Mark Lam.

        The JSC test JSTests/wasm/stress/oom.js tries to use all the
        available memory until an out of memory exception happens.

        The Linux kernel is more tuned for server workloads than for GUI
        responsiveness. When a process tries to use a lot of memory, Linux
        will do its best to serve the request. This usually translates to
        free physical RAM by writing to disk dirty pages and/or moving out
        less recently used pages to swap (disk storage).
        Meanwhile it does this, the system will become unresponsive and this
        leads to freezes that can last even some minutes on the worst cases.

        Therefore, let's skip this test on Linux as it will cause more harm
        than good on the Linux bots or on the machines of Linux developers.

        WebAssembly: remove empty test files
        https://bugs.webkit.org/show_bug.cgi?id=173382

        Reviewed by Saam Barati.

        The following files:
                JSTests/wasm/function-tests/call-indirect-params.js
                JSTests/wasm/function-tests/call-indirect.js
                JSTests/wasm/js-api/call-indirect-results.js
        Were changed to empty files in https://trac.webkit.org/changeset/209771

        They were testing call_indirect with the wrong semantics, before
        we implemented tables. That change implemented tables and
        therefore removed the erroneous tests.

        We have a few tests for call_indirect which already do the right thing:
                JSTests/wasm/function-tests/context-switch.js
                JSTests/wasm/function-tests/exceptions.js
                JSTests/wasm/function-tests/grow-memory-2.js
                JSTests/wasm/function-tests/stack-overflow.js
                JSTests/wasm/function-tests/table-basic-2.js
                JSTests/wasm/function-tests/table-basic.js
                JSTests/wasm/js-api/call-indirect.js

                JSTests/wasm/js-api/unique-signature.js
                JSTests/wasm/js-api/wrapper-function.js

        I also just imported the updated spec tests which, among other
        things, test call_indirect:
                core/br.wast
                core/br_table.wast
                core/call_indirect.wast
                core/func.wast
                core/func_ptrs.wast

                core/typecheck.wast
                core/unreachable.wast

        So I think it's OK to just delete the tests which should just have
        been deleted back when tables were added.

        WebAssembly: import updated spec tests
        https://bugs.webkit.org/show_bug.cgi?id=173287
        <rdar://problem/32725975>

        Reviewed by Saam Barati.

        Import spec tests as of 31c641cc15f2aedbec2fa45a5185f68416df578b,
        with a few modifications so things work.

        Fix a bunch of bugs found through this process, and punt a few tests (which I
        marked as blocked by this bug).

        Fixes:

        Fix load / store alignment: r216908 erroneously implemented it as bit alignment
        instead of byte alignment. It was also missing memory-alignment.js despite it
        being in the ChangeLog, so add it too. This allows spec-test/align.wast.js to
        pass.

        Tables can be imported or in a section. There can be only one, but sections can
        be empty. An Elements section can exist if there's no Table, as long as it is
        also empty.

        Memories can be imported or in a section. There can be only one, but sections
        can be empty. A Data section can exist if there's no Memory, as long as it is
        also empty.

        Prototypes: stringify without .prototype. in the string.

        WebAssembly.Table.prototype.grow was plain wrong: it takes a delta parameter,
        not a final size, and throws a RangeError on failure, not a TypeError.

        Fix compile / instantiate so the reject the promise if given an argument of the
        wrong type (instead of failing instantly).

        Fix async on neuter test.

        Element section shouldn't affect any Table if any of the elements are out of
        bounds. We need to process it in two passes.

        Segment section shouldn't affect any Data if any of the segments are out of
        bounds. We need to process it in two passes.

        Empty data segments are valid, but only when there is no memory. Their index
        still gets validated, and has to be zero.

        Punts:

        Error messages with context, the test seems overly restrictive but this is
        minor.

        compile/instantiate/validate property descriptors.

        UTF-8 bugs.

        Temporarily disable NaN tests. We need to go back and implement the following
        semantics: https://github.com/WebAssembly/spec/pull/414 This doesn't matter as
        much as getting all the other tests passing.

        Worth noting for NaNs: f64.no_fold_mul_one (also a NaN test) as well as
        no_fold_promote_demote (an interesting corner case which we get wrong). mul by
        one is (assert_return (invoke \"f64.no_fold_mul_one\" (i64.const
        0x7ff4000000000000)) (i64.const 0x7ff8000000000000)) which means converting sNaN
        to qNaN, and promote/demote is (assert_return (invoke \"no_fold_promote_demote\"
        (i32.const 0x7fa00000)) (i32.const 0x7fc00000)) which is the same. I'm not sure
        why they're not allowed.

        Restrict the regress-173035.js test to only run on Darwin x86-64.
        https://bugs.webkit.org/show_bug.cgi?id=173075

        Reviewed by Saam Barati.

        This is because the 32-bit x86 build will fail to mmap the 0x3f900000 bytes that
        this test will require to succeed.  Here's an example of this failure:
        https://build.webkit.org/builders/Apple%20Sierra%2032-bit%20JSC%20%28BuildAndTest%29/builds/866/steps/webkit-32bit-jsc-test/logs/stdio

        Since the issue is due to allocation of a very large amount of memory, the test
        will probably fail on iOS and other platforms as well.  Hence, we should just
        skip this test for any platforms that is not Darwin x86-64.

        Move slow-running microbenchmarks out of JSTests/microbenchmarks

        Reviewed by Saam Barati.
        
        The microbenchmarks directory is profitable when it's cheap to run. This change moves very slow
        tests (>=200ms running time on my machine) and puts them in JSTests/slowMicrobenchmarks instead.
        That directory is run only through `slow!; defaultQuickRun` and is not run by run-jsc-benchmarks.
        This is a big progression in test running time. But because it frontloads more slow tests, the
        tests will seem to run more slowly when you first start the test runner.

        <rdar://problem/29814999>

        Reviewed by Yusuke Suzuki.

        Based off these revisions:

        - wabt: d0d44702c753f851b094615298a2f4d4e3c21035

        The reason for the rebase is that wabt was updated to stop
        silently rejecting invalid modules. This was needed because
        some of the spec tests check to make sure that the module
        is invalid, but wabt was silently ignoring the errors and
        generating valid modules:

        WebAssembly: Import spec tests
        https://bugs.webkit.org/show_bug.cgi?id=166395

        Rubber stamped by Keith Miller.

        This patch implements the Wasm spec's tests found here:
        https://github.com/WebAssembly/spec/tree/master/interpreter/test
        
        These tests are in .wast s-epxression format. To convert
        them to JS, I use a script from the wabt library, found here:
        https://github.com/WebAssembly/wabt/blob/master/test/run-gen-spec-js.py
        
        I also added a script that automatically imports the tests as
        JS files. The inputs to the script is the path to the Wasm spec
        git repo and the path to the wabt git repo. This will make importing
        new tests easy in the future.

        The wasm spec imported is at commit: b055d01ea1dfdd7a5231ae779095435f836de97f
        The wabt used to do the import is at commit: 622b42dced6d793e9d49e9b1fd1d1524defd1387

        Fix 64-bit shift family Wasm opcodes
        https://bugs.webkit.org/show_bug.cgi?id=165902

        Reviewed by Geoffrey Garen.

        Add tests for shift family of instructions. Since
        we can't generate i64 values to pass to wasm we only compile
        the code for those functions. Attempting to generate any i64
        code using these instructions would have been enough to cause
        the B3 Validation error anyway.

        It's weird since the file is auto-generated and has been for a while. #164724 merely includes it in WasmFormat.h.

        Move Wasm tests to JS
        https://bugs.webkit.org/show_bug.cgi?id=164611

        Reviewed by Geoffrey Garen.

        This patch translates most of the tests from testWasm.cpp to the JS testing api. Most of the
        ommited tests were earliest tests, which tested trivial things, like adding two
        constants. Some tests are ommited for other reasons, however. These are:

        1) Tests using I64 since the testing api does not yet know how to handle 64-bit numbers.  2)
        Tests that would validate the memory of the module once wasm was done with it since that's
        not really possible in JS.

        In order to make such a translation easier this patch also adds some features to the JS
        testing api:

        1) Blocks can now be done lexically by adding a lambda as the last argument of the block
        opcode. For example one can do:
            ...
            .Block("i32", b => b.I32Const(1) )

        and the nested lambda will automatically have an end attached.

        2) The JS testing api can now handle inline signature types.

        3) Relocate some code to make it easier to follow and prevent 44 space indentation.

        4) Rename varuint/varint to varuint32/varint32, this lets them be directly called from the
        wasm.json without being remapped.

        5) Add support for Memory and Function sections to the Builder.

        6) Add support for local variables.

        On the JSC side, we needed to expose a new function to validate the compiled wasm code
        behaves the way we expect. At least until the JS Wasm API is finished. The new validation
        function, testWasmModuleFunctions, takes an array buffer containing the wasm binary, the
        number of functions in the blob and tests for each of those functions.

        WebAssembly JS API: implement more sections
        https://bugs.webkit.org/show_bug.cgi?id=164023

        Reviewed by Keith Miller.

        On the JSC side:

         - Put in parser stubs for all WebAssembly sections.
         - Parse Import, Export sections.
         - Use tryReserveCapacity instead of reserve, and bail out of the parser if it fails. This prevents the parser from bringing everything down when faced with a malicious input.
         - Encapsulate all parsed module information into its own structure, making it easier to pass around (from parser to Plan to Module to Instance).
         - Create WasmFormat.cpp to hold parsed module information's dtor to avoid including WasmMemory.h needlessly.
         - parseCode: avoid overflow through function size.
         - Remove all remainders of polyfill-prototype-1, and update license.
         - Add missing WasmOps.h and WasmValidateInlines.h auto-generation for cmake build.

        On the Builder.js testing side:

         - Implement Type, Import (function only), Export (function only) sections.
         - Check section order and uniqueness.
         - Optionally auto-generate the Type section from subsequent Export / Import / Code entries.
         - Allow re-exporting an import.

        WebAssembly API: implement Instance

        As described in: https://github.com/WebAssembly/design/blob/master/JS.md#webassemblyinstance-objects

         - Take ownership of Wasm::Plan's compilation result when successfully creating a JSWebAssemblyModule object.
         - Construct a basic Instance with a Module.
         - Handle second argument (importObject) of WebAssembly.Instance.
         - Add reference text from the spec to WebAssembly.Module's code.
         - Expose and test an empty 'exports' ModuleNamespaceObject on WebAssembly.Instance.

        The implementation isn't complete yet: it relies on further work for which I've filed bugs.

        WebAssembly JS API: implement Module

        This implementation allows us to:
         - Syncrhonously create a WebAssembly.Module with a typed array.
         - Creates a compilation plan.
         - Parse the Module and creates corresponding code.
         - Throw WebAssembly.CompileError with mildly helpful [*] error messages on
           failure.

        Consult the API documentation for expected behavior: https://github.com/WebAssembly/design/blob/master/JS.md#webassemblymodule-constructor

        For now the implementation discards the generated code.

        The next steps will be:
         - Expose a Module's exports.
         - Implement WebAssembly.Instance, which allows instantiating and running a
           compiled Module.
         - Beef up the testing infrastructure under JSTests/wasm so that more complex
           modules can be created and tested (instead of writing the bits by hand).

        This patch also:
         - Adds assert.instanceof in assert.js.
         - Refactors Wasm::Parser and friends to accept const uint8_t* as well as a
           Vector, to avoid copying when invoked synchronously.
         - Remove useless Structure from some of the wasm constructors: they're already
           on the JSGlobalObject, visited properly and all.
         - Fix off-by-one error in parsing: Parser::parseUInt32 failed if the integer
           was exactly at end of file.

        WebAssembly API: implement exception constructors properly

         - Rename WebAssemblyObject to JSWebAssembly for consistency.
         - WebAssembly object now has its own prototype: add WebAssemblyPrototype, and
           use it to register JSWebAssembly's function properties through auto-generated
           .lut.h, instead of manually.
         - The error constructors used to throw (e.g. `new WebAssembly.CompileError()`).
         - Register WebAssembly's constructors from the global object, and hold a
           reference to their structure and prototype so that invoking the constructor
           can use the structure directly from the global object.
         - Add a prototype base field to global object creation. Previous ones all had
           Object's prototype as their base, but WebAssembly's error constructors have
           Error as their base.
         - Test for the error object's correctness.
         - Add missing #if ENABLE(WEBASSEMBLY)

        JavaScript WebAssembly API: baby steps

         - Expand WebAssembly constructors into their own files. This requires a lot of
           boilerplate, as well as adding the .lut.h files. All of the
           JSWebAssembly*.{h,cpp}, as well as Constructor and Prototype files, are
           currently the same between the 4 specified WebAssembly constructors. It'll be
           easy to implement individual functions on constructed objects as per the
           spec, and have each of these files diverge. The error constructors are also
           similar, except that their instance derives from ErrorInstance.
         - Use constructor macro when initializing the global object.
         - Dramatically improve testing of the WebAssembly API by checking for
           properties specified in the spec [*].
         - Clean up assert.js' exception testing.
         - Fix a copy-paste bug in wasm.json: floating-point const return values were
           swapped.

        https://github.com/WebAssembly/design/blob/master/BinaryEncoding.md

        This DSL can then be used to write small text description of valid and invalid WebAssembly binaries, making testing the JSC implementation much easier.

            2. VarConst - variable operand 1, constant / literal operand 2
            3. ConstVar - constant / literal operand 1, variable operand 2

        We can prevent these tests from timing out by breaking each up to only run 1 of
        the 3 permutations of value types.

        Import Chakra tests to JSC
        https://bugs.webkit.org/show_bug.cgi?id=154697

        Reviewed by Saam Barati.

        Added Chakra tests.  All these tests are under Chakra/test.  This is the same layout
        for tests in the Chakra tree.

        Created a ChakraCore.yaml file to be used with run-jsc-stress-tests.  This file contains
        the tests that are run when the original Chakra runtests.py script is run.  That script
        is the test driver for *nix platforms and does not attempt to run all tests or all
        variations of tests.  The runtest.py driver consults rlexe.xml files in each test
        subdirectory to determine the test to run, the options to pass to the test and how to
        determine pass/fail of the test.  With runtests.py as the start, tests that didn't
        pass directly where either skipped, with a message describing why or through 
        adjustments to the test infrastructure, as described below, where made to pass.
        
        The only modification to the test infrastrucutre are:

         1) Added simple mapping of Chakra expected exception text to JSC expected text in
            test/UnitTestFramework/UnitTestFramework.js.  It would make sense to also
            map some JSC specific exception text to more generic text for the cases where
            that text contains indetifier names or other source specific strings and the
            Chakra equivolent exception texts are generic.  
 
         2) Created JSC specific expected text files where it is clear that the text work
            as expected on JSC but the test output is different.  Typically the differences
            fall into three categories, different exception output, different output from
            toString() of a function, slight numeric differences, and test that rely on
            iteration order.

         3) Stripped the CR's from the CR-LF line terminations of the files.  

        No actual test .js files were modified.

        However, when introducing, we wrap the `test()` with 1e4 to ensure the FTL compilation, and this
        increases the failure rate. By increasing the MAX in the test, we make the failures much more rare case.

        We should not keep the JavaScript tests inside the Source/JavaScriptCore/ directory.
        https://bugs.webkit.org/show_bug.cgi?id=160372

        Rubber stamped by Geoffrey Garen.

        This patch moves all the JavaScript tests from Source/JavaScriptCore/tests to
        a new top level directory, JSTests. Having the tests in the Source directory
        was both confusing an inconvenient for people that just want to checkout the
        source code of WebKit. Since there is no other obvious place to put all the
        JavaScript tests a new top level directory seemed the most sensible.

        * tests/: Deleted.
