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.

Jeffrey Yasskin e2595b5be6 r83391 was completely broken since Twines keep references to their inputs, and

Chris Lattner 28610b9878 don't use count + insert, just do insert + failure. Also, instead of deleting from

Chris Lattner e7c1e210c7 Several changes together in a murky mess:
1. Change some "\n" -> '\n'.
2. eliminte some std::string's by using raw_ostream::indent.
3. move a bunch of code out of the main arg parser routine into
   a new static HandlePrefixedOrGroupedOption function.
4. Greatly simplify the implementation of getOptionPred, and make
   it avoid splitting prefix options at = when that doesn't match
   a non-prefix option.

2009-09-20 01:11:23 +00:00
Chris Lattner 3b8adaf488 convert a bunch more stuff to use StringRef. The ArgName arguments are now
stringref because they may not be nul terminated.  For options like -Lfoo
this now avoids a O(n)  temporary std::strings where N is the length of 
the string after -L.

Dan Gohman e592923603 Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't
working. To support this, add an is_displayed() function to raw_ostream,
and generalize Process::StandardOutIsDisplayed and friends in order to
support it.

Also, call RemoveFileOnSignal before creating a file instead of after, so
that the file isn't left behind if the program is interrupted between when
the file is created and RemoveFileOnSignal is called.

While here, add a -S to llvm-extract and port it to IRReader so that it
supports assembly input.
