/*
*  Determine platform features, select feature selection defines
*  (e.g. _XOPEN_SOURCE), include system headers, and define DUK_USE_XXX
*  defines which are (only) checked in Duktape internal code for
*  activated features.  Duktape feature selection is based on automatic
*  feature detection, user supplied DUK_OPT_xxx defines, and optionally
*  a "duk_custom.h" user header (if DUK_OPT_HAVE_CUSTOM_H is defined).
*
*  When compiling Duktape, DUK_COMPILING_DUKTAPE is set, and this file
*  is included before any system headers are included.  Feature selection
*  defines (e.g. _XOPEN_SOURCE) are defined here before any system headers
*  are included (which is a requirement for system headers to work correctly).
*  This file is responsible for including all system headers and contains
*  all platform dependent cruft in general.  When compiling user code,
*  DUK_COMPILING_DUKTAPE is not defined, and we must avoid e.g. defining
*  unnecessary feature selection defines.
*
*  The general order of handling:
*    - Compiler feature detection (require no includes)
*    - Intermediate platform detection (-> easier platform defines)
*    - Platform detection, system includes, byte order detection, etc
*    - ANSI C wrappers (e.g. DUK_MEMCMP), wrappers for constants, etc
*    - DUK_USE_xxx defines are resolved based on input defines
*    - Duktape Date provider settings
*    - Final sanity checks
*
*  DUK_F_XXX are internal feature detection macros which should not be
*  used outside this header.

*  Feature selection (e.g. _XOPEN_SOURCE) must happen before any system
*  headers are included.  This header should avoid providing any feature
*  selection defines when compiling user code (only when compiling Duktape
*  itself).  If a feature selection option is required for user code to
*  compile correctly (e.g. it is needed for type detection), it should
*  probably be -checked- here, not defined here.
*
*  Date provider selection seems a bit out-of-place here, but since
*  the date headers and provider functions are heavily platform
*  specific, there's little point in duplicating the platform if-else
*  ladder.  All platform specific Date provider functions are in
*  duk_bi_date.c; here we provide appropriate #defines to enable them,
*  and include all the necessary system headers so that duk_bi_date.c
*  compiles.  Date "providers" are:
*
*    NOW = getting current time (required)
*    TZO = getting local time offset (required)
*    PRS = parse datetime (optional)
*    FMT = format datetime (optional)
*
*  There's a lot of duplication here, unfortunately, because many
*  platforms have similar (but not identical) headers, Date providers,
*  etc.  The duplication could be removed by more complicated nested
*  #ifdefs, but it would then be more difficult to make fixes which
*  affect only a specific platform.
*
*  XXX: add a way to provide custom functions to provide the critical
*  primitives; this would be convenient when porting to unknown platforms
*  (rather than muck with Duktape internals).

/*
*  ANSI C string/memory function wrapper defines to allow easier workarounds.

*
*  For instance, some platforms don't support zero-size memcpy correctly,
*  some arcane uclibc versions have a buggy memcpy (but working memmove)
*  and so on.  Such broken platforms can be dealt with here.
*
*  NOTE: ANSI C (various versions) and some implementations require that the
*  pointer arguments to memset(), memcpy(), and memmove() be valid values
*  even when byte size is 0 (even a NULL pointer is considered invalid in
*  this context).  Zero-size operations as such are allowed, as long as their
*  pointer arguments point to a valid memory area.  The DUK_MEMSET(),
*  DUK_MEMCPY(), and DUK_MEMMOVE() macros require this same behavior, i.e.:
*  (1) pointers must be valid and non-NULL, (2) zero size must otherwise be
*  allowed.  If these are not fulfilled, a macro wrapper is needed.

*
*  Not sure what's the required behavior when a pointer points just past the
*  end of a buffer, which often happens in practice (e.g. zero size memmoves).
*  For example, if allocation size is 3, the following pointer would not
*  technically point to a valid memory byte:
*
*    <-- alloc -->
*    | 0 | 1 | 2 | .....
*                  ^-- p=3, points after last valid byte (2)
*
*  If this is a practical issue, wrappers are again needed.

/*
*  Union to access IEEE double memory representation, indexes for double
*  memory representation, and some macros for double manipulation.
*
*  Also used by packed duk_tval.  Use a union for bit manipulation to
*  minimize aliasing issues in practice.  The C99 standard does not
*  guarantee that this should work, but it's a very widely supported
*  practice for low level manipulation.
*
*  IEEE double format summary:
*
*    seeeeeee eeeeffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff
*       A        B        C        D        E        F        G        H
*
*    s       sign bit
*    eee...  exponent field
*    fff...  fraction
*
*  See http://en.wikipedia.org/wiki/Double_precision_floating-point_format.
*
*  NaNs are represented as exponent 0x7ff and mantissa != 0.  The NaN is a
*  signaling NaN when the highest bit of the mantissa is zero, and a quiet
*  NaN when the highest bit is set.
*
*  At least three memory layouts are relevant here:
*
*    A B C D E F G H    Big endian (e.g. 68k)           DUK_USE_DOUBLE_BE
*    H G F E D C B A    Little endian (e.g. x86)        DUK_USE_DOUBLE_LE
*    D C B A H G F E    Mixed/cross endian (e.g. ARM)   DUK_USE_DOUBLE_ME
*
*  ARM is a special case: ARM double values are in mixed/cross endian
*  format while ARM duk_uint64_t values are in standard little endian
*  format (H G F E D C B A).  When a double is read as a duk_uint64_t
*  from memory, the register will contain the (logical) value
*  E F G H A B C D.  This requires some special handling below.
*
*  Indexes of various types (8-bit, 16-bit, 32-bit) in memory relative to
*  the logical (big endian) order:
*
*  byte order      duk_uint8_t    duk_uint16_t     duk_uint32_t
*    BE             01234567         0123               01
*    LE             76543210         3210               10
*    ME (ARM)       32107654         1032               01
*
*  Some processors may alter NaN values in a floating point load+store.
*  For instance, on X86 a FLD + FSTP may convert a signaling NaN to a
*  quiet one.  This is catastrophic when NaN space is used in packed
*  duk_tval values.  See: misc/clang_aliasing.c.

/*
*  Double NaN manipulation macros related to NaN normalization needed when
*  using the packed duk_tval representation.  NaN normalization is necessary
*  to keep double values compatible with the duk_tval format.
*
*  When packed duk_tval is used, the NaN space is used to store pointers
*  and other tagged values in addition to NaNs.  Actual NaNs are normalized
*  to a specific format.  The macros below are used by the implementation
*  to check and normalize NaN values when they might be created.  The macros
*  are essentially NOPs when the non-packed duk_tval representation is used.
*
*  A FULL check is exact and checks all bits.  A NOTFULL check is used by
*  the packed duk_tval and works correctly for all NaNs except those that
*  begin with 0x7ff0.  Since the 'normalized NaN' values used with packed
*  duk_tval begin with 0x7ff8, the partial check is reliable when packed
*  duk_tval is used.
*
*  The ME variant below is specifically for ARM byte order, which has the
*  feature that while doubles have a mixed byte order (32107654), unsigned
*  long long values has a little endian byte order (76543210).  When writing
*  a logical double value through a ULL pointer, the 32-bit words need to be
*  swapped; hence the #ifdefs below for ULL writes with DUK_USE_DOUBLE_ME.
*  This is not full ARM support but suffices for some environments.
