{- Note [Foreign call results]
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~
A foreign call always returns an unboxed tuple of results, one
of which is the state token.  This seems to happen even for pure
calls.

Even if we returned a single result for pure calls, it'd still be
right to wrap it in a singleton unboxed tuple, because the result
might be a Haskell closure pointer, we don't want to evaluate it. -}

-- This function is used to work around the fact that many array
-- primops take Int# arguments, but we interpret them as unsigned
-- quantities in the code gen. This means that we have to be careful
-- every time we work on e.g. a CmmInt literal that corresponds to the
-- array size, as it might contain a negative Integer value if the
-- user passed a value larger than 2^(wORD_SIZE_IN_BITS-1) as the Int#
-- literal.

-- TODO: Several primop implementations (e.g. 'doNewByteArrayOp') use
-- ByteOff (or some other fixed width signed type) to represent
-- array sizes or indices. This means that these will overflow for
-- large enough sizes.

-- TODO: Several primops, such as 'copyArray#', only have an inline
-- implementation (below) but could possibly have both an inline
-- implementation and an out-of-line implementation, just like
-- 'newArray#'. This would lower the amount of code generated,
-- hopefully without a performance impact (needs to be measured).

-- | The big function handling all the primops.
--
-- In the simple case, there is just one implementation, and we emit that.
--
-- In more complex cases, there is a foreign call (out of line) fallback. This
-- might happen e.g. if there's enough static information, such as statically
-- know arguments.

  -- Note [QuotRem optimization]

  --
  -- `quot` and `rem` with constant divisor can be implemented with fast bit-ops
  -- (shift, .&.).
  --
  -- Currently we only support optimization (performed in GHC.Cmm.Opt) when the
  -- constant is a power of 2. #9041 tracks the implementation of the general
  -- optimization.
  --
  -- `quotRem` can be optimized in the same way. However as it returns two values,
  -- it is implemented as a "callish" primop which is harder to match and
  -- to transform later on. For simplicity, the current implementation detects cases
  -- that can be optimized (see `quotRemCanBeOptimized`) and converts STG quotRem
  -- primop into two CMM quot and rem primops.

   With some bit-twiddling, we can define int{Add,Sub}Czh portably in
   C, and without needing any comparisons.  This may not be the
   fastest way to do it - if you have better code, please send it! --SDM

   Return : r = a + b,  c = 0 if no overflow, 1 on overflow.

   We currently don't make use of the r value if c is != 0 (i.e.
   overflow), we just convert to big integers and try again.  This
   could be improved by making r and c the correct values for
   plugging into a new J#.

   { r = ((I_)(a)) + ((I_)(b));                                 \
     c = ((StgWord)(~(((I_)(a))^((I_)(b))) & (((I_)(a))^r)))    \
         >> (BITS_IN (I_) - 1);                                 \
   }
   Wading through the mass of bracketry, it seems to reduce to:
   c = ( (~(a^b)) & (a^r) ) >>unsigned (BITS_IN(I_)-1)

-- Note [Comparing stable names]
-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
--
-- A StableName# is actually a pointer to a stable name object (SNO)
-- containing an index into the stable name table (SNT). We
-- used to compare StableName#s by following the pointers to the
-- SNOs and checking whether they held the same SNT indices. However,
-- this is not necessary: there is a one-to-one correspondence
-- between SNOs and entries in the SNT, so simple pointer equality
-- does the trick.

-- NOTE [SIMD Design for the future]
-- Check to make sure that we can generate code for the specified vector type
-- given the current set of dynamic flags.
-- Currently these checks are specific to x86 and x86_64 architecture.
-- This should be fixed!
-- In particular,
-- 1) Add better support for other architectures! (this may require a redesign)
-- 2) Decouple design choices from LLVM's pseudo SIMD model!
--   The high level LLVM naive rep makes per CPU family SIMD generation is own
--   optimization problem, and hides important differences in eg ARM vs x86_64 simd
-- 3) Depending on the architecture, the SIMD registers may also support general
--    computations on Float/Double/Word/Int scalars, but currently on
--    for example x86_64, we always put Word/Int (or sized) in GPR
--    (general purpose) registers. Would relaxing that allow for
--    useful optimization opportunities?
--      Phrased differently, it is worth experimenting with supporting
--    different register mapping strategies than we currently have, especially if
--    someday we want SIMD to be a first class denizen in GHC along with scalar
--    values!
--      The current design with respect to register mapping of scalars could
--    very well be the best,but exploring the  design space and doing careful
--    measurements is the only way to validate that.
--      In some next generation CPU ISAs, notably RISC V, the SIMD extension
--    includes  support for a sort of run time CPU dependent vectorization parameter,
--    where a loop may act upon a single scalar each iteration OR some 2,4,8 ...
--    element chunk! Time will tell if that direction sees wide adoption,
--    but it is from that context that unifying our handling of simd and scalars
--    may benefit. It is not likely to benefit current architectures, though
--    it may very well be a design perspective that helps guide improving the NCG.
