Reid Spencer 7957de7949 Implement arbitrary integer constants through the use of APInt values. 
Positive, negative, and hexadecimal integer constants will now return an
APInt for values having > 64 bits of precision.

 2007-02-28 02:24:27 +00:00
Reid Spencer 9875fc1500 Implement support for aribrary precision integers by creating two new 
tokens: ESAPINTVAL and EUAPINTVAL and adding an APInt* as a semantic value.
This allows us to extend the definition of an integer constant to allow
arbitrary precision integer constant values.

Reid Spencer f8470272a7 getActiveWords should return the number of words, not the index of the 
highest active words. Increment its result by one.

instead of honoring the client's requested bit width.

Reid Spencer 31acef50ad Implement countLeadingOnes() and getMinSignedBits(). This helps to minimize 
the bit width of negative numbers by computing the minimum bit width for a
negative value. E.g. 0x1800000000000000 could be just 0x8000000000000000
