Outputable Width

Defined in GHC.Cmm.Type

Methods

ppr :: Width -> SDoc

widthInBits :: Width -> Int

A width in bits.

widthInBytes :: Width -> Int

A width in bytes.

widthFromBytes (widthInBytes w) === w

widthInLog :: Width -> Int

log_2 of the width in bytes, useful for generating shifts.

widthFromBytes :: Int -> Width

• Partial* A width from the number of bytes.

wordWidth :: Platform -> Width

The width of the current platform's word size.

halfWordWidth :: Platform -> Width

The width of the current platform's half-word size.

cIntWidth :: Platform -> Width

halfWordMask :: Platform -> Integer

A bit-mask for the lower half-word of current platform.

narrowU :: Width -> Integer -> Integer

Narrow a signed or unsigned value to the given width. The result will reside in [0, +2^width).

>>> narrowU W8 256    == 256
>>> narrowU W8 255    == 255
