   3         Unreviewed, disable module tests in Windows until name resolution is fixed

   5
   6         Until bug[1] is fixed, we disable the module tests.
   7         Since the local file system name resolution is just implemented in jsc.cpp and
   8         is intended to be used for the module tests, it does not affect JSC framework
   9         and WebKit itself.

  21
  22         The IDIV instruction on x86 divides the value in the EDX:EAX registers
  23         by the source operand and stores the quotient in EAX and the remainder
  24         in EDX. Therefore, we store the values that we don't want to be
  25         overwritten by IDIV in registers that are not EAX or EDX. This patch
  26         makes the intention clearer and makes the code easier to read.

  37
  38         JSDollarVMPrototype needs to be updated to match http://trac.webkit.org/changeset/189160 i.e.
  39         remove the use of JSC::Function bit in its property attributes.

  46         Unreviewed, fix the module name resolution in Windows
  47         https://bugs.webkit.org/show_bug.cgi?id=148689
  48
  49         Attempt to fix the module name resolution in Windows.
  50         A module name is represented as the UNIX path under the current module tests.
  51         This fix split the module name with '/' instead of pathSeparator().
  52
  53         This is only utilized by the jsc.cpp for the local module tests.
  54         So, WebKit production and JavaScriptCore framework are not affected by this change.

  64         Web Inspector: tighten up lifetimes for Agent-owned objects, and initialize agents using contexts
  65         https://bugs.webkit.org/show_bug.cgi?id=148625
  66
  67         Reviewed by Joseph Pecoraro.
  68
  69         All agents own their domain-specific frontend and backend dispatchers. Change so that
  70         they are initialized in constructors rather than when a frontend connects or disconnects.
  71         This may cause additional memory use, but this can be counteracted by lazily creating
  72         some agents that are not required for other agents to function (i.e., runtime and page agents).
  73
  74         To avoid adding frontend/backend dispatcher arguments to every single agent constructor,
  75         change agent construction to take a AgentContext or a subclass of it. This provides agents with
  76         references to objects in the owning InspectorEnvironment subclass that are guaranteed to
  77         outlive all agents. AgentContext and its subclasses follow the existing Agent class hierarchy.

 188
 189         Enable ES6 Modules in JSC shell by default. Compile time flag is left for WebCore.
 190         Since the entry point to evaluate the modules are completely separated from the usual
 191         entry point to evaluate the script, we can safely enable ES6 modules in JSC shell.

 469         Reviewed by Michael Saboff.
 470
 471         In the present code, after ping-pong'ing back and forth between native and JS
 472         code a few times, if we have a stack overflow on re-entry into the VM to run
 473         JS code's whose stack frame would overflow the JS stack, the code will end up
 474         unwinding past the native function that is making the call to re-enter the VM.
 475         As a result, any clean up code (e.g. destructors for stack variables) in the
 476         skipped native function frame (and its chain of native function callers) will
 477         not be called.
 478
 479         This patch is based on the Michael Saboff's fix of this issue landed on the
 480         jsc-tailcall branch: http://trac.webkit.org/changeset/188555
 481
 482         We now check for the case where there are no JS frames to unwind since the
 483         last native frame, and treat the exception as an unhandled exception.  The
 484         native function is responsible for further propagating the exception if needed.
 485
 486         Other supporting work:
 487         1. Remove vm->vmEntryFrameForThrow.  It should always be the same as
 488            vm->topVMEntryFrame.
 489         2. Change operationThrowStackOverflowError() to use the throwStackOverflowError()
 490            helper function instead of rolling its own.
 491         3. In the LLINT vm entry, set vm->topVMEntryFrame as soon as the entry frame is
 492            fully initialized (instead of waiting).  With this, we can always reliably
 493            tell which VMEntryFrame is on top.
 494         4. Added a test that exercises this edge case.  The test should not hang or crash.

 639         Instead of a singleton, it should be possible to have multiple channels open
 640         at the same time and to individually close channels as frontends come and go.
 641
 642         The FrontendRouter class keeps a list of open FrontendChannels and sends messages
 643         to the appropriate frontends based on whether the message is a response or event.
 644         Each InspectorController owns a single FrontendRouter and BackendDispatcher instance.
 645         Inspector backend code that sends messages to the frontend should switch over to
 646         using the router rather than directly using a FrontendChannel.

 946         [ES6] Instantiate Module Environment bindings and execute module
 947         https://bugs.webkit.org/show_bug.cgi?id=148053
 948
 949         Reviewed by Saam Barati.
 950
 951         This patch implements Module Environment binding instantiation.
 952         And since the layout of the module environment is tightly coupled with the variable
 953         look up in LLInt / Baseline / DFG, we implement the execution part at the same time.
 954
 955         For the instantiation, we implement the several operations (like resolveExport)
 956         specified in the spec. The original algorithm contains the recursive call, but it is not
 957         good for C++ code. We flatten the algorithm by using the manual frames to avoid recursions.
 958         By leveraging the information retrieved by the above operations, we instantiate and
 959         initialize the slots of the module environment.
 960
 961         The module namespace object is not implemented yet in this patch. It will be implemented
 962         and instantiated in the module environment in the subsequent patch[1].
 963
 964         To look up the imported module bindings in the JS code, we introduce the "ModuleVar" resolve
 965         type for resolve_scope, get_from_scope and put_to_scope. This "ModuleVar" will be filled
 966         when linking the CodeBlock. This type is used when treating the imported bindings.
 967
 968         1. For resolve_scope, when linking, we resolve the actual module environment where
 969             looked up variable resides and store it directly to the instruction. And resolve_scope
 970             simply retrieve the stored pointer from the instruction.
 971
 972         2. For get_from_scope, since "ModuleVar" behavior for get_from_scope is completely same
 973             to the "ClosureVar", we just store "ClosureVar" for get_from_scope to eliminate
 974             unnecessary branch in LLInt layer.
 975
 976         3. For put_to_scope, we always emit the function call that immediately raises the error.
 977             Because all the imported bindings are immutable and module code is always strict code.
 978             In DFG, we just emit the ForceOSRExit. We don't make put_to_scope with "ModuleVar"
 979             "CannotCompile" because it disables DFG compiling for the function even if this
 980             problematic instruction is never executed.
 981
 982         Exported module variables inside the original module environment are just treated as the
 983         usual heap variables. So the types for closure variables are just used. ("ClosureVar" etc.)

1098         Web Inspector: InspectorController should support multiple frontend channels
1099         https://bugs.webkit.org/show_bug.cgi?id=148538
1100
1101         Reviewed by Joseph Pecoraro.
1102
1103         Instead of a singleton, it should be possible to have multiple channels open
1104         at the same time and to individually close channels as frontends come and go.
1105
1106         The FrontendRouter class keeps a list of open FrontendChannels and sends messages

1177         [ES6] Recognize calls in tail position

1182         This patch adds the capability for the bytecode generator to recognize
1183         and dispatch tail calls, as per ES6 spec:

1227         We should have more tests in strict mode to have better test coverage.
1228         This adds a copy of the v8-v6 tests from SunSpider as JSC stress tests,
1229         with "use strict"; added at the top of the files.
1230
1231         A few modifications were necessary to make the files valid in strict
1232         mode, namely adding a couple of "var" statements and removing some
1233         generated code in earley-boyer that was using strings with octal
1234         escapes.

2791
2792         We had some resetStub...() methods in CodeBlock that didn't really do anything that
2793         StructureStubInfo couldn't do by itself. It makes sense for the functionality to reset a
2794         stub to be in the stub class, not in CodeBlock.
2795
2796         It's still true that:
2797
2798         - In order to mess with a StructureStubInfo, you either have to be in GC or you have to
2799           be holding the owning CodeBlock's lock.
2800
2801         - StructureStubInfo doesn't remember which CodeBlock owns it (to save space), and all
2802           of the callers of StructureStubInfo methods know which CodeBlock own it. So, many stub

2830
2831         This patch implements the addition and subtraction instructions in
2832         WebAssembly using a stack-based approach: each instruction reads its
2833         operands from the top of the 'temporary' stack, pops them, and
2834         optionally pushes a return value to the stack. Since operands are passed
2835         on the stack, we don't use the arguments that are passed to the methods
2836         of WASMFunctionCompiler, and we don't use the return values from these
2837         methods. (We will use them when we implement LLVM IR generation for

2883
2884         This changes register naming conventions in the llint and baseline JIT
2885         in order to use as few (native) callee-save registers as possible on
2886         64-bits platforms. It also introduces significant changes in the way
2887         registers names are defined in the LLint and baseline JIT in order to
2888         enable a simpler convention about which registers can be aliased. That
2889         convention is valid across all architecture, and described in
2890         llint/LowLevelInterpreter.asm.
2891
2892         Callee save registers are now called out regCS<n> (in the JIT) or
2893         csr<n> (in the LLInt) with a common numbering across all tiers. Some
2894         registers are unused in some tiers.
2895
2896         As a part of this change, rdi was removed from the list of temporary
2897         registers for X86-64 Windows as it is a callee saves register. This
2898         reduced the number of temporary registers for X86-64 Windows.

3087         Initial implementation of WebAssembly function compiler
3088         https://bugs.webkit.org/show_bug.cgi?id=148734
3089
3090         Reviewed by Filip Pizlo.
3091
3092         This patch introduces WASMFunctionCompiler, a class for generating
3093         baseline JIT code for WebAssembly functions. The source for each
3094         WebAssembly function is parsed in two passes.
3095         - The first pass is done by WASMFunctionSyntaxChecker when the
3096           WebAssembly module is initialized. It validates the syntax,
3097           determines the start and the end offsets in the source, and
3098           calculates the stack height of the function.
3099         - The second pass is done by WASMFunctionCompiler when the function
3100           is about to be executed.
3101         This patch doesn't calculate the correct stack height nor generate
3102         the correct code. That will be done in a subsequent patch.

3131         Block scoped variables should be visible across scripts
3132         https://bugs.webkit.org/show_bug.cgi?id=147813
3133
3134         Reviewed by Filip Pizlo.
3135
3136         This patch properly implements the global lexical tier described in
3137         http://www.ecma-international.org/ecma-262/6.0/index.html#sec-globaldeclarationinstantiation.
3138         The sepcification mandates that there is a global lexical environment
3139         that wrtaps all program execution. This global lexical environment
3140         holds let/const/class variables defined at the top-level scope
3141         inside a program. These variables can never shadow other program-level
3142         "var"s, global object properties, or other global lexical environment
3143         declarations. Doing so is a SyntaxError.
3144
3145         This patch adds new ResolveTypes that describe the global lexical environment:
3146         GlobalLexicalVar and GlobalLexiclaVarWithInjectionChecks. Resolving to
3147         these means we're doing a load/store from the JSGlobalLexicalEnvironment.
3148         This patch also addes new ResolveTypes: UnresolvedProperty and
3149         UnresolvedPropertyWithVarInjectionChecks. Before, we used GlobalProperty
3150         to encompass this category because if JSScope::abstractAccess didn't
3151         resolve to anything, we could safely assume that this property is
3152         on the global object. Such an assumption is no longer true in ES6.
3153         When we have a resolve_scope/put_to_scope/get_from_scope with this
3154         ResolveType, we try to transition it to either a GlobalProperty
3155         ResolveType or a GlobalLexicalVar resolve type.
3156
3157         JSGlobalLexicalEnvironment is a subclass of JSSegmentedVariableObject.
3158         This means get_from_scopes are direct pointer reads and
3159         put_to_scopes are direct pointer stores.
