On 32-bit systems FXXXConvertI64 instructions are compiled to calls to C functions. The TF node for the function call is already generated in the wasm compiler, the lowering of the I64 parameter is done in the Int64Lowering.

Add StringLessThanStub, StringLessThanOrEqualStub, StringGreaterThanStub and StringGreaterThanOrEqualStub, based on the CodeStubAssembler, and hook them up with TurboFan (and Ignition). The stubs are currently essentially comparable with the StringCompareStub, which is now obsolete. We can later extend these stubs to cover more interesting cases (i.e. two byte sequential string comparisons, etc.).

According to https://www.w3.org/TR/html5/obsolete.html#dom-document-all the undetectable bit (for document.all) only affects comparisons with undefined and null. In particular comparisons with other values are not affected, so we can actually simplify the handling of undetectable a lot by only checking it when null or undefined might be involved (this is actually in line with what the CompareIC does).

port 2689548e (r34459) original commit message: These new stubs perform exactly the same job as the string equality case for the CompareIC, but are platform independent and usable outside of fullcodegen and Crankshaft. We use them in the StrictEqualStub and the StrictNotEqualStub instead of falling back to the runtime immediately for String comparisons, and we also use them in TurboFan to perform String equality or inequality comparisons. These stubs currently handle only internalized and one byte strings w/o going to C++, but it should be easy to add support for more string cases later, i.e. utilizing already flattened cons strings or comparing two byte strings as well.

ES2015 generally bans FunctionDeclarations in positions which expect a Statement, as opposed to a StatementListItem, such as a FunctionDeclaration which constitutes the body of a for loop. However, Annex B 3.2 and 3.4 make exceptions for labeled function declarations and function declarations as the body of an if statement in sloppy mode, in the latter case specifying that the semantics are as if the function declaration occurred in a block. Chrome has historically permitted further extensions, for the body of any flow control construct. This patch addresses both the syntactic and semantic mismatches between V8 and the spec. For the semantic mismatch, function declarations as the body of if statements change from unconditionally hoisting in certain cases to acquiring the sloppy mode function in block semantics (based on Annex B 3.3). For the extra syntax permitted, this patch adds a flag, --harmony-restrictive-declarations, which excludes disallowed function declaration cases. A new UseCounter, LegacyFunctionDeclaration, is added to count how often function declarations occur as the body of other constructs in sloppy mode. With this patch, the code generally follows the form of the specification with respect to parsing FunctionDeclarations, rather than allowing them in arbitrary Statement positions, and makes it more clear where our extensions occur.

CallSite depends on using the function name to get ahold of the property name from which an exception was thrown. This fix properly handles the ES2015 names for getters and setters.

LUI instruction would sign extend into higher 32bits, in that case we might need to use DAHI, DATI to overwrite the extension. The bug will occur when we are loading some addresses such as 0x00007fffffffxxxx.

This adds new code stubs for abstract relational comparison, namely LessThanStub, LessThanOrEqualStub, GreaterThanStub and GreaterThanOrEqualStub, and hooks them up for Ignition and TurboFan. These stubs implement the full compare operation without any unpredictable bailouts. Currently they still go to C++ for string comparisons, and also use the %ToPrimitive_Number runtime entry, as we still lack a stub for the ToPrimitive operation. These issues will be addressed separately in follow-up CLs. Drive-by-fix: Add support for deferred code in the RawMachineAssembler and CodeStubAssembler. A block can be marked as deferred by marking its Label as deferred, which will then make the register allocator penalize this block and prefer better register assignments for the other blocks.

This is more consistent with the current naming scheme (i.e. IsCallable for callable bit on map, IsConstructor for constructor bit on map, and now IsUndetectable for undetectable bit on map). Also simplify the fallthrough case for Object::Equals, because we don't need to check for Null or Undefined or Undetectable, as both Null and Undefined already have the undetectable bit set on their maps.
