* Implemented llvm::sys::locale::columnWidth and isPrint for the case of ↵Alexander Kornienko2013-08-072-0/+87
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | This is a follow up patch for r187390 to implement the parser for the Windows-style command line.

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186986 91177308-0d34-0410-b5e6-96231b3b80d8
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186984 91177308-0d34-0410-b5e6-96231b3b80d8

* [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.

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186559 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185184 91177308-0d34-0410-b5e6-96231b3b80d8
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185059 91177308-0d34-0410-b5e6-96231b3b80d8
