Compilation Notes:
------------------
	gcc or LLVM clang is required for compiling Mednafen.  Intel's C compiler may work, but is untested.
	Probably doesn't need to be said, but the compilers optionally specified via CC and CXX *must* be the same version.

	clang: 3.5.0 or newer is required, though gcc 4.9.x is preferable for performance reasons.

	gcc: 4.8(4.8.4+), or 4.9(4.9.2+) or newer is required.  gcc 4.9 is recommended; gcc 5.x and gcc 6.x tend to produce
	slower executables, at least with Mednafen on x86_64.

	Reportedly, passing:	--build=x86_64-apple-darwin`uname -r`
	to the configure script is necessary for building on Mac OS X to work properly.

	Compiling at -O3 or higher, or with other custom optimization flags, is discouraged.


---------------------------------------------
Some notes(and reminders) on the source code:
---------------------------------------------
	Check "mednafen/src/types.h" for standard C and C++ library header includes, and avoid #include'ing the same files redundantly elsewhere.

	Avoid %= in save state load variable sanitizing code unless the variable is unsigned.

	malloc(), realloc(), calloc()'ing 0 bytes of memory may return a NULL pointer.

	memcpy()/memmove()/etc. with NULL pointers is undefined and bad even when length is 0.

	Careful to not do something like: void somefunc(int something[16]); [...] sizeof(something)

	Try to avoid writing new code that violates strict overflow(even though we compile with -fwrapv), especially be mindful
	of stuff like what's described at http://kqueue.org/blog/2013/09/17/cltq/

	Order of operations != Operator precedence.  Remember sequence point rules, and don't do stuff like:
		value = FuncWithSideEffects() | (FuncWithSideEffects() << 8);	// BAD BAD
	See: http://en.cppreference.com/w/cpp/language/eval_order

	Avoid writing new code that shifts left signed integers or negative values to avoid technically undefined behavior; use
	ugly typecasting, or multiply by powers of 2 instead(remotely modern compilers can optimize it to a shift internally).

	Vanishing temporaries: https://gcc.gnu.org/onlinedocs/gcc/Temporaries.html#Temporaries

	Do not place a period before the field width for "s" and "[" conversion specifiers in *scanf() format strings; perhaps a bad
	habit picked up long ago from working with a buggy libc or trio?

	Avoid compiling different C++ files with different compiler flags in regards to instruction set used(like -mmmx, -msse, -mfpmath, -march),
	or else there may be (template-)function ODR violations that could cause compatibility problems.

	GPLv3-incompatible code:
		WonderSwan emulation code from Cygne.
		QuickLZ(old version used)

	Don't do greater-than and less-than comparisons between pointers unless they're pointers to members of the same array/struct/etc.

	Avoid using a pointer into a nested array of a multidimensional array to access elements of the multidimensional array that lie outside of that specific
	nested array, as such behavior is probably undefined.

	Pointer provenance, DR260.

	Don't create temporarily-invalid pointers via careless pointer arithmetic; restructure the expressions if possible, or utilize uintptr_t instead.

	x86_64 inline assembly, stack red zone.

	https://gcc.gnu.org/onlinedocs/gccint/Memory-model.html#Memory-model

	Don't use memcmp() on class/struct objects unless they're initialized with memset() and copied around with only memcpy()(or equivalent).

	Don't rely on malloc(), realloc(), and calloc() setting errno to ENOMEM on a memory allocation error.


---------------------------------------------
Code contributions:
---------------------------------------------
	To keep things simpler for commercial licensing, any patches or new code offered for emulation modules "apple2", "psx", "snes_faust", and "ss",
	along with contributions to core Mednafen functionality with code that is not self-contained(e.g. support for a new CD image format), will be ignored.
	Distributing a separate patch set or an outright fork(with branding that clearly conveys the forkiness) is recommended.
