The free-block tracker search in BaseHeap::AllocRange treats
high_page_number as inclusive, shifting allocator-returned addresses
by one stride relative to the old loop-based search. Some titles
encode allocator-returned addresses in PPC code and break when that
layout shifts (Far Cry 3, Far Cry 4, Watchdogs).
In addition, reapply xe::align on the high side of AllocRange
(essentially reverting c28019e33). Without the round-up, a caller
passing a min/max window exactly the size of its request loses a
stride at the top and fails the early page_count size check.
A lightweight cross-platform/compiler compatibility library.
This library presupposes C++11/14 support. As more compilers get C++14 it will
assume that.
Other parts of the project use this to avoid creating spaghetti linkage. Code
specific to the emulator should be kept out, as not all of the projects that
depend on this need it.
Where possible, C++11/14 STL should be used instead of adding any code in here,
and the code should be kept as small as possible (by reusing STL/etc). Third
party dependencies should be kept to a minimum.
Target compilers:
MSVC++ 2013+
Clang 3.4+
GCC 4.8+.
Target platforms:
Windows 8+ (_win.cc suffix)
Mac OSX 10.9+ (_mac.cc suffix, falling back to _posix.cc)
Linux ? (_posix.cc suffix)
Avoid the use of platform-specific #ifdefs and instead try to put all
platform-specific code in the appropriately suffixed cc files.
