Comment (by thomie):
In `libraries/base/GHC/Base.hs`:
{{{#!haskell
maxInt, minInt :: Int
{- Seems clumsy. Should perhaps put minInt and MaxInt directly into
MachDeps.h -}
#if WORD_SIZE_IN_BITS == 31
minInt = I# (-0x40000000#)
maxInt = I# 0x3FFFFFFF#
#elif WORD_SIZE_IN_BITS == 32
minInt = I# (-0x80000000#)
maxInt = I# 0x7FFFFFFF#
#else
minInt = I# (-0x8000000000000000#)
maxInt = I# 0x7FFFFFFFFFFFFFFF#
#endif
}}}
