Bug: v8:6148 Cq-Include-Trybots: master.tryserver.chromium.linux:linux_chromium_rel_ng Change-Id: I3529d7ed757a7ab49a001af8641cf888db171cdb Reviewed-on: https://chromium-review.googlesource.com/570047 Reviewed-by: Yang Guo <yangguo@chromium.org> Commit-Queue: Peter Marshall <petermarshall@chromium.org> Cr-Commit-Position: refs/heads/master@{#46838}	2017-07-24 10:38:55 +00:00
Ross McIlroy	69a645d3c6	[TurboFan] Enable typed lowering of JSStringConcat to ConsString allocation. ... Adds typed lowering of JSStringConcat to ConsString allocation if the following conditions hold: - All concatinations will result in a ConsString of >= ConString::kMinLength - No concatinations will result in a empty string in the RHS unless there is a sequential string in the LHS. This also means JSStringConcat needs an eager checkpoint since it can deopt if throwing a RangeError when the string length protector is valid.
