There is no good reason to have the meat of most objects' initialization logic in heap.cc, all wrapped by the CALL_HEAP_FUNCTION macro. Instead, this CL changes the protocol between Heap and Factory to be AllocateRaw, and all object initialization work after (possibly retried) successful raw allocation happens in the Factory. This saves about 20KB of binary size on x64.

This reverts commit 10817205. While increasing the number of IRREGEXP regexp instances (vs. ATOM) gives us a 3% perf improvement, it also results in higher memory overhead. This CL is the suspected culprit for the recent 5x increase in OOM crashes from within regexp codegen.

This patch normalizes the casing of hexadecimal digits in escape sequences of the form `\xNN` and integer literals of the form `0xNNNN`. Previously, the V8 code base used an inconsistent mixture of uppercase and lowercase. Google’s C++ style guide uses uppercase in its examples: https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters Moreover, uppercase letters more clearly stand out from the lowercase `x` (or `u`) characters at the start, as well as lowercase letters elsewhere in strings.

A while ago, CharacterRange::AddCaseEquivalents used to operate on a single range (the `this` value) and add case equivalents for that to `ranges`. This was changed in a2baaaac to use `ranges` as a list of incoming operands instead. When we now determine that the current range does not have case equivalents, we need to `continue` instead of `return` to avoid skipping the remaining ranges in the list.

When the range of all non-bmp characters is passed to AddUnicodeCaseEquivalents, icu::UnicodeSet::closeOver dutifully tries to case-fold every single character in that range. Since we already know this to be a nop, we can simply return instead. This improves compilation time of /ui regexps by around 100x.

Regexp code flushing support has been unintentionally disabled for quite a while without any signals on our benchmarks. This CL completely removes support.

Did only work with full MCs. Since the majority of GCs is now incremental and will be concurrent in future this becomes obsolete.

The condition only applies in unicode mode, where any lone surrogates are desugared into a character class (and will not be considered in this optimization). Non-unicode mode treats lone surrogates exactly like any other codepoint. BUG=chromium:711092 Review-Url: https://codereview.chromium.org/2808403006 Cr-Commit-Position: refs/heads/master@{#44638}

Previously the Boyer-Moore-Horspool optimization gave up in the presence of a submatch. A submatch is where we record the current position so that we can go back to it, which is an essential part of the semantics of lookarounds (lookaheads and lookbehinds). This has been the case since Boyer-Moore-Horspool was implemented, but it was overly cautious. * For positive lookahead it is OK to use the patterns inside the lookahead to guide the BMS optimization. * For positive lookbehind we harmlessly fail to optimize when the patterns inside the lookbehind go backwards because TextNode::EatsAtLeast returns 0. * For negative lookarounds, the NegativeLookaroundChoiceNode::FillInBMInfo method (in jsregexp.h) knows to only look at the following pattern. This is in response to disappointing lookbehind performance in Atom.
