Benjamin Kramer 0ef736fef2 Turns out llvm-gcc still uses SplitString with a vector. Add it back until I

llvm-svn: 93163
 2010-01-11 18:44:35 +00:00
Benjamin Kramer c6fe3c3273 Reimplement getToken and SplitString as "StringRef helper functions" 
- getToken is modeled after StringRef::split but it can split on multiple
  separator chars and skips leading seperators.
- SplitString is a StringRef::split variant for more than 2 elements with the
  same behaviour as getToken.

Douglas Gregor 09470e6a4e Switch StringRef::edit_distance over to using raw pointers, since both

John McCall dd5044ac55 Implement support for converting to string at "natural precision", and fix some 
major bugs in long-precision conversion.

llvm-svn: 92150
 2009-12-24 23:18:09 +00:00
John McCall e6212ace38 Substantially optimize APFloat::toString() by doing a single large divide to 
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
 2009-12-24 12:16:56 +00:00
John McCall 29b5c284ae Add accessors for the largest-magnitude, smallest-magnitude, and 
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.

 2009-12-23 17:03:46 +00:00
David Greene 64506db8e8 Provide dbgs(), a circular-buffering debug output stream. By default it 
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
 2009-12-23 16:39:06 +00:00
David Greene 7ffbb50edf Add circular_raw_ostream, which buffers its output in a circular queue 
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
 2009-12-23 16:08:15 +00:00
Chris Lattner dd3e9aaad3 Make some methods const. The only interesting change here is that 
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.

Daniel Dunbar ff53d4694c Add an implementation of the delta debugging algorithm. 
- This is a pretty slow / memory intensive implementation, and I will likely
   change it to an iterative model, but it works.

Mikhail Glushenkov 5551c207cd Move the handling of CommaSeparated options into ProvideOption. 
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.
