https://github.com/tc39/ecma262/pull/778 was recently merged to Ecma 262. It changes the way to convert between "local time" and UTC in such a way that it'd work for all timezones whether or not there has been any change in the timezone offset of the standard time. For instance, Europe/Moscow and some parts of US state of Indiana have changed the standard (non-DST) timezone offset a few times. The previous spec assumes that the the standard timezone offset is constant, but the new spec take into account the offset change history. In addition, it specifies a new way to calculate the timezone offset during a timezone transition (either in and out of DST or timezone offset shift). During a negative transition (e.g. fall backward / getting out of DST), repeated times are to be interpreted as if the offset before the transition is in effect. During a positive transition (e.g. spring forward / getting into DST), skipped times are to be treated similarly. That is, they are to be interpreted as if the offset before the transition is in effect. With icu-timezone-data, v8 is compliant to the new spec for the past and the future as well as now whether or not the standard timezone offset of a given timezone has changed over time (e.g. Europe/Moscow, Pacific/Apia). With icu-timezone-data, Australia/Lord_Howe (30 minute DST change) also works per spec. Without icu-timezone-data, it works only for timezones of which the standard timezone offset is the same as the current offset (e.g. most North American timezones other than parts of Indiana) and of which the DST shift is an hour. For instance, it doesn't work for Europe/Moscow in 2010 when the standard timezone offset was +4h because the current (2018) standard timezone offset is +3h. Neither does it for Lord Howe in Australia with the DST shift of 0.5 hr. This CL used to require one of the two ICU CLs below, but not any more. https://chromium-review.googlesource.com/c/chromium/deps/icu/+/572652 https://chromium-review.googlesource.com/851265 (a proposed CL to the upstream ICU).

- Moves base::VirtualMemory to v8::internal::VirtualMemory. - Makes VirtualMemory platform-independent by moving internals to new OS:: static methods, for each platform. This will make it easier to delegate memory management in VirtualMemory to V8::Platform, so that embedders like Blink can override it. We can't depend on V8::Platform in base/platform.

Currently every VirtualMemory allocation on 64-bit systems uses a random 46-bit address hint for ASLR. This leads to wired page leak on MacOS discovered by Erik Chen (see crbug.com/700928 and https://chromium-review.googlesource.com/c/557958/): "The Darwin kernel [as of macOS 10.12.5] does not clean up page directory entries [PDE] created from mmap or mach_vm_allocate, even after the region is destroyed. Using a virtual address space that is too large causes a leak of about 1 wired [can never be paged out] page per call to mmap(). The page is only reclaimed when the process is killed." This patch changes VirtualMemory to accept the hint parameter explicitly. On MacOS the hints are confined to 4GB contiguous region. Algorithm: - On startup, set heap.mmap_region_base_ to a random address. - For each mmap use heap.mmap_region_base_ + (random_offset % (4*GB)).

Affects the Windows case where we over reserve for alignment reasons but actually already get aligned memory. Implemented on allocator level to potentially cover other platforms as well.

AllocateGuarded previously fell back on Allocate and then called Guard to set the protection to PROT_NONE. Linux commits RW memory, but the important thing here is to reserve the address space without committing it. This change adds a new variant of Allocate that takes explicit permission bits so that AllocateGuarded allocates non-RW memory from the beginning.

This refactoring is preparatory work to enable ICU to be the backend for timezone information rather than system calls. In the process, a bit of code duplication that was inserted in the Solaris port patch is eliminated here among modern POSIX backends. One possible performance downside of this patch is that it introduces a virtual method call for operations which were previously not virtual methods. However, a couple factors mitigate this effect: - The DateCache minimizes the need for calls into the TimezoneCache - These calls were already not very high performance, as they included a system call which requires an RPC to get out of the sandbox, and they are surrounded by C++ builtins, which require a JS to C++ transition. - A future transition to ICU, enabled by this refactoring, may improve performance by eliminating the system call.

Currently only the Win64 bots report this warnings, which adds quite some overhead to the development process. With this flag we also get compiler warnings about implicit 64bit to 32bit truncations when building with clang on Linux/x64 and Mac/x64.

With -std=g++0x, `signbit` is no longer a define, and is an actual function declared in C++-specific headers. Thus checking it's presence with ifdef will no longer work. Considering that g++0x implies newer compiler, there should not be the case where it won't be present anymore.
