* Handle storage complications of float->float conversions.Neil Booth2007-09-221-18/+23
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42220 91177308-0d34-0410-b5e6-96231b3b80d8
* Change APFloat::convertFromInteger to take the incomingDale Johannesen2007-09-212-17/+20
| | | | | | | | | | | | bit width instead of number of words allocated, which makes it actually work for int->APF conversions. Adjust callers. Add const to one of the APInt constructors to prevent surprising match when called with const argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42210 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | double from some of the many places in the optimizers it appears, and do something reasonable with x86 long double. Make APInt::dump() public, remove newline, use it to dump ConstantSDNode's. Allow APFloats in FoldingSet. Expand X86 backend handling of long doubles (conversions to/from int, mostly). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41967 91177308-0d34-0410-b5e6-96231b3b80d8

They could be used to implement much of APInt, but the idea is they are enough to implement APFloat as well, which the current APInt interface is not suited for.

| | | | | | | | | | | contents of the set were small, deallocate and shrink the set. This avoids having us to memset as much data, significantly speeding up some pathological cases.
