* fix indentation, fit in 80 cols.Chris Lattner2009-12-291-382/+382

* fix .cpp file to not wrap the entire file in namespace blocks.Chris Lattner2009-12-291-30/+23

* Implement support for converting to string at "natural precision", and fix someJohn McCall2009-12-241-16/+26
| | | | | | major bugs in long-precision conversion. llvm-svn: 92150
* Substantially optimize APFloat::toString() by doing a single large divide toJohn McCall2009-12-241-0/+37
| | | | | | | | | | | | cut the significand down to the desired precision *before* entering the core divmod loop. Makes the overall algorithm logarithmic in the exponent. There's still a lot of room for improvement here, but this gets the performance back down to acceptable-for-diagnostics levels, even for long doubles. negligible, even on long doubles. llvm-svn: 92130
* Add accessors for the largest-magnitude, smallest-magnitude, andJohn McCall2009-12-241-0/+301
| | | | | | | | smallest-normalized-magnitude values in a given FP semantics. Provide an APFloat-to-string conversion which I am quite ready to admit could be much more efficient. llvm-svn: 92126
* Set Remainder before Quotient in case Quotient and LHS alias. The newJohn McCall2009-12-241-1/+1
| | | | | | order should be immune to such problems. llvm-svn: 92124

| | | | llvm-svn: 92003
* Provide dbgs(), a circular-buffering debug output stream. By default itDavid Greene2009-12-231-1/+55
| | | | | | | | simply passes output to errs(). If -debug-buffer-size=N is set N > 0, dbgs() buffers its output until program termination and dumps the last N characters sent to it. This is handy when debugging very large inputs. llvm-svn: 92002
* Add circular_raw_ostream, which buffers its output in a circular queueDavid Greene2009-12-231-0/+47
| | | | | | | | and outputs it when explicitly flushed. The intent is to use it in situations such as debug output logging where a signal handler can take care of flushing the buffer at program termination. llvm-svn: 92001
* Make some methods const. The only interesting change here is thatChris Lattner2009-12-192-15/+17
| | | | | | | | it changes raw_fd_ostream::preferred_buffer_size to return zero on a scary stat failure instead of setting the stream to an error state. This method really should not mutate the stream. llvm-svn: 91740
* now that libsystem no longer uses SmallVector, we can move Chris Lattner2009-12-162-0/+38
| | | | | | SmallVectorBase::grow_pod out of line, finally satisfying PR3758. llvm-svn: 91529

* Add an implementation of the delta debugging algorithm.Daniel Dunbar2009-12-032-0/+111
| | | | | | | - This is a pretty slow / memory intensive implementation, and I will likely change it to an iterative model, but it works. llvm-svn: 90447

* Move the handling of CommaSeparated options into ProvideOption.Mikhail Glushenkov2009-11-201-23/+33
| | | | | | | | Makes '--comma-separated val1,val2' mean the same thing as '--comma-separated=val1,val2' (that is, 'val1' and 'val2' are not lumped together as 'val1,val2'). Also declutters the main loop a bit. llvm-svn: 89463
