* Several changes together in a murky mess:Chris Lattner2009-09-201-84/+102
| | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82362 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82345 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-141-2/+2
| | | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8
