This removes the thread-local field in question. This side-channel for the "caught exception" is not needed, we can just explicitly pass the exception value to all support functions. Also, there is an inherent problem with having this side-channel, as it will not be properly reset when an exception handler ends up not rethrowing the exception.

This reverts two CLs that were intended to show symbols for embedded builtins in chromecrash. The symbols never showed up, a part of this must still be missing. Revert "[builtins] Declare builtin symbols as globals" This reverts commit 8412353c. Revert "[builtins] Declare builtin symbols" This reverts commit 17ad3ae4.

Use BuiltinAssemblerOptions to generate AssemblerOptions when generating the bytecode handlers (assuming v8_enable_embedded_bytecode_handlers is on). Mark all but InvokeIntrinsic, InvokeIntrinsicWide, InvokeIntrinsicExtraWide, TestIn, TestInWide, TestInExtraWide and TestTypeOf as isolate-independent. The excluded handlers create jump tables which have absolute addresses.

The AtomicNarrow operations are currently used for wider 64-bit operations, that only operate on 32-bits of data or less (Ex:I64AtomicAdd8U). Removing these because this can be handled in int64-lowering by zeroing the higher order node. Explicitly zeroing these in code-gen is not required because - - The spec requires only the data exchange to be atomic, for narrow ops this uses only the low word. - The return values are not in memory, so are not visible to other workers/threads BUG:v8:6532 Change-Id: I90a795ab6c21c70cb096f59a137de653c9c6a178 Reviewed-on: https://chromium-review.googlesource.com/1194428Reviewed-by:

On 32-bit platforms, String::kMaxLength is such that not all BigInts can be converted to Strings. NoSideEffectsToString, however, used to assume that this conversion always succeeds. This patch adds a check for the failure case, and returns "<a very large BigInt>" instead of crashing. This change is practically unobservable, because actually formatting such a huge BigInt to String would take "forever", which is also why there is no regression test.

The new node is introduced for literal string addition and calling String.prototype.concat in the typed lowering phase. It later might get optimized away during redundancy elimination, keeping the performance of already existing benchmarks with string addition. In case the operation is about to throw (due to too long string being constructed) we just deoptimize, reusing the interpreter logic for creating the error. Modify relevant mjsunit and unit tests for string concatenation.
