* For PR1205:Reid Spencer2007-02-261-16/+49
| | | | | | | | | | 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
* 1. Make sure all delete operators of arrays use the array form of delete.Reid Spencer2007-02-261-19/+45
| | | | | | | | | | | | | | 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. llvm-svn: 34646

* 1. Remove redundant calls to clearUsedBits().Reid Spencer2007-02-261-44/+79
| | | | | | | | | | 2. Fix countTrailingZeros to use a faster algorithm. 3. Simplify sext() slightly by using isNegative(). 4. Implement ashr using word-at-a-time logic instead of bit-at-a-time 5. Rename locals named isNegative so they don't clash with method name. 6. Fix fromString to compute negated value correctly. llvm-svn: 34629

* in X86-64 CCC, i8/i16 arguments are already properly zext/sext'd on input.Chris Lattner2007-02-261-14/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Capture this so that downstream zext/sext's are optimized out. This compiles: int test(short X) { return (int)X; } to: _test: movl %edi, %eax ret instead of: _test: movswl %di, %eax ret GCC produces this bizarre code: _test: movw %di, -12(%rsp) movswl -12(%rsp),%eax ret llvm-svn: 34623
* Fold (sext (truncate x)) more aggressively, by avoiding creation of aChris Lattner2007-02-261-10/+34
| | | | | | | | | sextinreg if not needed. This is useful in two cases: before legalize, it avoids creating a sextinreg that will be trivially removed. After legalize if the target doesn't support sextinreg, the trunc/sext would not have been removed before. llvm-svn: 34621
* track signedness of formal argument, though we have a fixme here.Chris Lattner2007-02-261-0/+8

* Rewrite lshr to not do bit by bit copy but to copy and shift whole words.Reid Spencer2007-02-261-15/+42
| | | | | | This makes it much more efficient. llvm-svn: 34618
* Fix sext operation. Shifting by zero would leave an incorrect mask.Reid Spencer2007-02-251-1/+1

* 1. Fix the flip() method to correctly flip all words of the APInt.Reid Spencer2007-02-251-13/+89

* fix CodeGen/X86/2007-02-25-FastCCStack.ll, a regression from my patch lastChris Lattner2007-02-251-1/+1

* Rework GlobalValue::removeDeadConstantUsers to always remove dead constantChris Lattner2007-02-251-21/+29
| | | | | | | | | | exprs hanging off a global, even if the global is not otherwise dead. This requires some tricky iterator gymnastics. This implements Transforms/GlobalOpt/constantexpr-dangle.ll by deleting a constantexpr that made it appear that the address of the function was taken. llvm-svn: 34608

* 1. Provide more detail in file comment.Reid Spencer2007-02-251-189/+145
| | | | | | | | | | | | | | 2. Move comments for methods to .h file, delete them in .cpp file. 3. All places that were doing manual clear of high order bits now call the clearUnusedBits() method in order to not depend on undefined behavior of the >> operator when the number of bits shifted equals the word size. 4. Reduced # of loc by using the new result of clearUnusedBits() method. 5. Simplified logic (decreased indentation) in a few places. 6. Added code comments to larger functions that needed them. 7. Added FIXME notes about weak implementations of things (e.g. bit-by-bit shift right is sub-optimal). llvm-svn: 34603
