Chris Lattner eb09e28ccc bugfix: fastcall does not require the first two params to be marked 'inreg', 
they always get registers.

Reid Spencer e1f3f1919c For PR1205: 
Convert ConstantRange class to use APInt internally as its value type for
the constant range, instead of ConstantInt.

Reid Spencer 91d3b3fce9 Make the trunc/sext/zext methods return APInt& so that these operations 
can be chained together with other operations.

 2007-02-28 17:34:32 +00:00
Reid Spencer 074b8a080e Make APInt a little more friendly to its users: 
* Add support for + and - of a uint64_t.
  * Make trunc/sext/zext return *this so it can be chained with other ops
  * Add smin, smax, umin, umax functions for getting min/max values.

the bit width of negative numbers by computing the minimum bit width for a

   to the bitwidth.

Reid Spencer b31bffed96 For PR1205: 
Implement the first step towards arbitrary precision integer support in
LLVM. The APInt class provides arbitrary precision arithmetic and value
representation. This patch changes ConstantInt to use APInt as its value
representation without supporting bit widths > 64 yet. That change will
come after ConstantFolding handles bit widths > 64 bits.

llvm-svn: 34647
 2007-02-26 23:54:03 +00:00
Reid Spencer 7c16cd2746 1. Make sure all delete operators of arrays use the array form of delete. 
2. Rewrite operator=(const APInt& RHS) to allow the RHS to be a different
   bit width than the LHS. This makes it possible to use APInt as the key
   of a DenseMap, as needed for the IntConstants map in Constants.cpp
3. Fix operator=(uint64_t) to clear unused bits in case the client assigns
   a value that has more bits than the APInt allows.
4. Assert that bit widths are equal in operator==
5. Revise getHashValue() to put the bit width in the low order six bits.
   This should help to make i1 0, i2 0, ... i64 0 all distinct in the
   IntConstants DenseMap.
