-- Encode numbers in LEB128 encoding.
-- Requires one byte of space per 7 bits of data.
--
-- There are signed and unsigned variants.
-- Do NOT use the unsigned one for signed values, at worst it will
-- result in wrong results, at best it will lead to bad performance
-- when coercing negative values to an unsigned type.
--
-- We mark them as SPECIALIZE as it's extremely critical that they get specialized
-- to their specific types.
--
-- TODO: Each use of putByte performs a bounds check,
--       we should use putPrimMax here. However it's quite hard to return
--       the number of bytes written into putPrimMax without allocating an
--       Int for it, while the code below does not allocate at all.
--       So we eat the cost of the bounds check instead of increasing allocations
--       for now.

{-
Finally - a reasonable portable Integer instance.

We used to encode values in the Int32 range as such,
falling back to a string of all things. In either case
we stored a tag byte to discriminate between the two cases.

This made some sense as it's highly portable but also not very
efficient.

However GHC stores a surprisingly large number off large Integer
values. In the examples looked at between 25% and 50% of Integers
serialized were outside of the Int32 range.

Consider a valie like `2724268014499746065`, some sort of hash
actually generated by GHC.
In the old scheme this was encoded as a list of 19 chars. This
gave a size of 77 Bytes, one for the length of the list and 76
since we encod chars as Word32 as well.

We can easily do better. The new plan is:

* Start with a tag byte
  * 0 => Int64 (LEB128 encoded)
  * 1 => Negative large interger
  * 2 => Positive large integer
* Followed by the value:
  * Int64 is encoded as usual
  * Large integers are encoded as a list of bytes (Word8).
    We use Data.Bits which defines a bit order independent of the representation.
    Values are stored LSB first.

This means our example value `2724268014499746065` is now only 10 bytes large.
* One byte tag
* One byte for the length of the [Word8] list.
* 8 bytes for the actual date.

The new scheme also does not depend in any way on
architecture specific details.

We still use this scheme even with LEB128 available,
as it has less overhead for truely large numbers. (> maxBound :: Int64)

The instance is used for in Binary Integer and Binary Rational in basicTypes/Literal.hs

-- | Information we keep around during interface file
-- serialization/deserialization. Namely we keep the functions for serializing
-- and deserializing 'Name's and 'FastString's. We do this because we actually
-- use serialization in two distinct settings,
--
-- * When serializing interface files themselves
--
-- * When computing the fingerprint of an IfaceDecl (which we computing by
--   hashing its Binary serialization)
--
-- These two settings have different needs while serializing Names:
--
-- * Names in interface files are serialized via a symbol table (see Note
--   [Symbol table representation of names] in BinIface).
--
-- * During fingerprinting a binding Name is serialized as the OccName and a
--   non-binding Name is serialized as the fingerprint of the thing they
--   represent. See Note [Fingerprinting IfaceDecls] for further discussion.
