2009-09-20Several changes together in a murky mess:Chris Lattner
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

2009-09-20convert argname to StringRef, simplifying LookupOption.Chris Lattner

2009-09-20convert 'Value' to StringRef which makes it easier to Chris Lattner
maintain the "null is unspecified, empty is empty" semantics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82351 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-20Change CommaSeparated processing to do it with StringRef instead of ↵Chris Lattner
temporary std::strings. This requires StringRef'izing ProvideOption which I also did. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82350 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-20convert a bunch more stuff to use StringRef. The ArgName arguments are nowChris Lattner
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

2009-09-19convert a bunch of std::strings to use StringRef. This should eliminateChris Lattner
a massive number of temporary strings created when parsing a command line. More still left to eliminate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82318 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
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
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
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

2008-10-14Fix command-line option printing to print two spaces where needed,Dan Gohman
instead of requiring all "short description" strings to begin with two spaces. This makes these strings less mysterious, and it fixes some cases where short description strings mistakenly did not begin with two spaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57521 91177308-0d34-0410-b5e6-96231b3b80d8

for a target-dependent default with a command-line override; this way should be generally usable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37285 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-12improve the patch for PR1318 to also support grouped options with customChris Lattner
handlers (like the pass list). My previous fix only supported *new* command line options, not additions to old ones. This fixes test/Feature/load_module.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35935 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes llvm-ar. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35727 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-06rearchitect the registration mechanism used by the command line option stuff.Chris Lattner
This dramatically reduce the amount of memory allocated by the commandline stuff at static init time, changing it to build local data structures when ParseCommandLineOptions is called. In a dummy empty program that links some llvm libraries, this reduces the number of malloc'd bytes from 4864 to 3360 on entry to main. Most of that memory is now allocated by non-commandline related stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35701 91177308-0d34-0410-b5e6-96231b3b80d8
