2009-10-06r83391 was completely broken since Twines keep references to their inputs, andJeffrey Yasskin
some of the inputs were temporaries. Here's a real fix for the miscompilation. Thanks to sabre for pointing out the problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83417 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-06Bugfix for the CommaSeparated option. The original code was adding the wholeNicolas Geoffray
string at the end of the list, instead of the last comma-separated string. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83405 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-26remove support for "NoSub" from regex. It seems like a minor optimizationChris Lattner
and makes the API more annoying. Add a Regex::getNumMatches() method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82877 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-24add and document regex support for FileCheck. You can now do stuff like:Chris Lattner

2009-09-24Roll back r82348, which introduced an infinite loop in ParseCStringVector() thatJeffrey Yasskin
a trivial unittest would have caught. This revision also adds the trivial unittest. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82675 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-22Switch FoldingSet::AddString to StringRef based API.Daniel Dunbar
- This also fixes a dereference of std::string::end, which makes MSVC unhappy and was causing all the static analyzer clang tests to fail. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82517 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-22Workaround what I believe is an MSVC bug where it emits a definition for aDaniel Dunbar
static const class member into each translation unit, with external linkage??? - If someone understands this issue better, please clue me in, I haven't consulted the standard yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82516 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-20eliminate the duplicate detection loop, moving it into the loop that ↵Chris Lattner
populates the Opts vector in the first place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82367 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-20don't use count + insert, just do insert + failure. Also, instead of ↵Chris Lattner
deleting from the middle of a vector, swap the last element in and pop_back. Also saves 330 bytes :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82365 91177308-0d34-0410-b5e6-96231b3b80d8

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 '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

common and useful integer types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82338 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

2009-09-11Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn'tDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81568 91177308-0d34-0410-b5e6-96231b3b80d8
