Bug 1256535 - Disable C4577 to unblock compilation on VS2015; r?poiru As part of unblocking building with VS2015u1 in automation, I'm mass disabling compiler warnings that are turned into errors. This is not the preferred mechanism to fix compilation warnings. So hopefully this patch never lands because someone insists of fixing the underlying problem instead. But if it does land, hopefully the workaround is only temporary. MozReview-Commit-ID: CnmHTfEZpBK

Bug 1186060 - Build with Visual Studio 2015 Update 1; r?ted, ehsan This commit switches Windows builds from Visual Studio 2013 to Visual Studio 2015 Update 1. Previously, Visual Studio was installed on the builers as part of the base system image. Starting with this commit, we obtain Visual Studio from a pre-generated, self-contained archive containing the executables, Windows SDK, and other support files. This means that new Windows toolchains can be installed without having to modify configuration of machines in automation! The mozconfigs for Visual Studio 2015 are a bit different from existing mozconfigs. Because it appears to be completely redundant and not necessary, the LIBPATH variable has been dropped. The order of paths in PATH, LIB, and INCLUDE has changed. The new order more accurately reflects what would be defined by vcvarsall.bat. As part of switching to Visual Studio 2015, the Universal CRT is now required. So, the 2015 mozconfigs export WIN_UCRT_REDIST_DIR to define the location to those files. The switch to Visual Studio 2015 also involves the switch from the Windows 8.1 SDK to the Windows 10 SDK. However, we still target an old version of Windows, so this hopefully shouldn't have any significant fallout. It's worth noting that switching to Visual Studio 2015 makes builds - especially PGO builds - significantly faster. Our PGO build times in automation are ~1 hour faster. Our regular builds appear to be a few minutes faster. MozReview-Commit-ID: Pa5GW8V87Q

Bug 1253707 - Script to generate visual studio toolchain archive; r?ted Previously, Windows toolchains and related dependencies (SDKs, etc) were installed on Windows builders by people responsible for maintaining those machines. This commit takes a step in a new direction. We introduce a script (complete with documentation) that can produce a zip archive (or any archive format if people want to implement support) of the toolchain files. Basically, you install Visual Studio 2015 Community, run the script, and produce a self-contained zip file containing everything from Microsoft you need to build Firefox. With a copy of this archive and an installation of MozillaBuild, it is possible to build Firefox on a fresh Windows installation. No time-consuming Visual Studio installation needed. The goal is to upload these archives to tooltool and have our Windows builders download and extract them at run-time. At which time, we can remove all the other Visual Studio and SDK files from builders because they don't need to be baked into the image. We may find tooltool's caching isn't good enough and we have to more aggressively caching the standalone toolchain files. But that is a problem for another day. Whatever happens, we'll need the functionality in this script to produce a self-contained archive of the toolchain. There are certainly files in the produced archive that aren't needed. I think perfect is the enemy of done and we can prune the archive over time, if wanted. MozReview-Commit-ID: EckEK1a6vA3

Bug 1124033 - Replace blanket disabling of VS2015 warnings with C5026 and C5027; r?ehsan Wv:18 was added in bug 1119072 as a quick way to get the tree building with VS2015. Now that we're closer to rolling out VS2015 support, we want to expose its new warnings. This patch replaces the blanket disabling of new warnings in VS2015 with just disabling C5026 and C5027, which relate to symbols being implicitly defined as deleted. MozReview-Commit-ID: 8uniydfNJns

Bug 1255239 - Reduce size of HuffmanIncomingTables. r=hurley. Splitting Each HuffmanIncomingTable into two parts avoids the wasted 0/nullptr fields and allows the remaining fields to be packed more efficiently. Making them all const allows them to be shared between processes. On 64-bit platforms this saves (60*N - 7.5) KiB, where N is the number of processes.
