* Changed isPrint for U+00AD SOFT HYPHEN to return true.Alexander Kornienko2013-08-081-4/+8
| | | | | | | | | | | | | | | | | Summary: This is consistent with MacOSX implementation, and most terminals actually display this character (checked on gnome-terminal, lxterminal, lxterm, Terminal.app, iterm2). Actually, this is in line with the ISO Latin 1 standard (ISO 8859-1), which defines it differently from the Unicode Standard.

| | | | | | | | | | | | | | | | | | | | | generic UTF8-capable terminal. Summary: This is a second attempt to get this right. After reading the Unicode Standard I came up with the code that uses definitions of "printable" and "column width" more suitable for terminal output (i.e. fixed-width fonts and special treatment of many control characters). The implementation here can probably be used for Windows and MacOS if someone can test it properly. The patch addresses PR14910.

* Introduce Regex::isLiteralERE function.Peter Collingbourne2013-08-051-0/+15
| | | | | | | | | This will be used to implement an optimisation for literal entries in special case lists. Differential Revision: http://llvm-reviews.chandlerc.com/D1278 llvm-svn: 187731
* Update incorrect file headers.Sean Silva2013-08-011-1/+1
| | | | | | One of these was spotted in review by Rafael. llvm-svn: 187598
* Fix windows' implementation of status when a file doesn't exist.Rafael Espindola2013-07-311-0/+4
| | | | | | | | | The unix one was returning no_such_file_or_directory, but the windows one was return success. Update the one one caller that was depending on the old behavior. llvm-svn: 187463

* Implement TokenizeWindowsCommandLine.Rui Ueyama2013-07-301-9/+28
| | | | | | | | | | This is a follow up patch for r187390 to implement the parser for the Windows-style command line. This should follow the rule as described at http://msdn.microsoft.com/en-us/library/windows/desktop/17w5ykft(v=vs.85).aspx Differential Revision: http://llvm-reviews.chandlerc.com/D1235 llvm-svn: 187430
* Include st_dev to make the result of getUniqueID actually unique.Rafael Espindola2013-07-291-3/+3
| | | | | | This will let us use getUniqueID instead of st_dev directly on clang. llvm-svn: 187378
* Don't end a file name with a dot. It looks odd.Rafael Espindola2013-07-251-0/+5
| | | | llvm-svn: 187124
* Refactor the unit test for MemoryBuffer::getOpenFileSliceEli Bendersky2013-07-231-6/+27
| | | | | | | Run in two different modes: with and without reopening the temporary file between creating it and mapping it with MemoryBuffer. llvm-svn: 186986
* Split getOpenFile into getOpenFile and getOpenFileSlice.Rafael Espindola2013-07-231-7/+4
| | | | | | | | | | | | | | | | The main observation is that we never need both the filesize and the map size. When mapping a slice of a file, it doesn't make sense to request a null terminator and that would be the only case where the filesize would be used. There are other cleanups that should be done in this area: * A client should not have to pass the size (even an explicit -1) to say if it wants a null terminator or not, so we should probably swap the argument order. * The default should be to not require a null terminator. Very few clients require this, but many end up asking for it just because it is the default. llvm-svn: 186984
* Add a simple unit test for MemoryBuffer::getOpenFileEli Bendersky2013-07-221-0/+33
| | | | llvm-svn: 186887
* Add a unit test for checking that we respect the F_Binary flag.Rafael Espindola2013-07-191-0/+31

* [Support] Beef up and expose the response file parsing in llvm::clReid Kleckner2013-07-181-0/+24
| | | | | | | | | | | | | | | | | | | The plan is to use it for clang and lld. Major behavior changes: - We can now parse UTF-16 files that have a byte order mark. - PR16209: Don't drop backslashes on the floor if they don't escape anything. The actual parsing loop was based on code from Clang's driver.cpp, although it's been rewritten to track its state with control flow rather than state variables.

| | | | llvm-svn: 186561
* Fix a regression I introduced back in r178147.Rafael Espindola2013-07-181-0/+25
| | | | | | | | | | | We don't want cast and dyn_cast to work on temporaries. They don't extend lifetime like a direct bind to a reference would, so they can introduce hard to find bugs. I added tests to make sure we don't regress this. Thanks to Eli Friedman for noticing this and for his suggestions on how to test it. llvm-svn: 186559
* Add a wrapper for open.Rafael Espindola2013-07-161-2/+1
| | | | | | | This centralizes the handling of O_BINARY and opens the way for hiding more differences (like how open behaves with directories). llvm-svn: 186447
* [Support] Add a Unicode conversion wrapper from UTF16 to UTF8Reid Kleckner2013-07-162-0/+66
| | | | | | | | | | | This is to support parsing UTF16 response files in LLVM/lib/Option for lld and clang. Reviewers: hans Differential Revision: http://llvm-reviews.chandlerc.com/D1138 llvm-svn: 186426

* Add a division operator to BlockFrequency.Jakob Stoklund Olesen2013-06-281-0/+18
| | | | | | | | | | | Allow a BlockFrequency to be divided by a non-zero BranchProbability with saturating arithmetic. This will be used to compute the frequency of a loop header given the probability of leaving the loop. Our long division algorithm already saturates on overflow, so that was a freebie. llvm-svn: 185184
* Add a convenience createUniqueDirectory function.Rafael Espindola2013-06-272-10/+2
| | | | | | | | | | | There are a few valid situation where we care about the structure inside a directory, but not about the directory itself. A simple example is for unit testing directory traversal. PathV1 had a function like this, add one to V2 and port existing users of the created temp file and delete it hack to using it. llvm-svn: 185059
* Remove unused includes.Rafael Espindola2013-06-261-1/+0

| | | | | | I will remove the V1 version as soon as I change clang in the next commit. llvm-svn: 184914
* Revert "BlockFrequency: Saturate at 1 instead of 0 when multiplying a ↵Benjamin Kramer2013-06-211-12/+1

* BlockFrequency: Saturate at 1 instead of 0 when multiplying a frequency with ↵Benjamin Kramer2013-06-211-1/+12
| | | | | | | | | | | | | | | a branch probability. Zero is used by BlockFrequencyInfo as a special "don't know" value. It also causes a sink for frequencies as you can't ever get off a zero frequency with more multiplies. This recovers a 10% regression on MultiSource/Benchmarks/7zip. A zero frequency was propagated into an inner loop causing excessive spilling. PR16402. llvm-svn: 184584

* Modified the implementation of fs::GetUniqueID on Windows such that it ↵Aaron Ballman2013-06-191-0/+36

* Remove the program class.Rafael Espindola2013-06-121-3/+3
| | | | | | | It was only used to implement ExecuteAndWait and ExecuteNoWait. Expose just those two functions and make Execute and Wait implementations details. llvm-svn: 183864
* Move PathV2.h to Path.hRafael Espindola2013-06-112-2/+2
| | | | | | | Most clients have already been moved from Path V1 to V2. The ones using V1 now include PathV1.h explicitly. llvm-svn: 183801
