2016-06-21[Docs] More warning fixes to unbreak the docs buildbot.George Burgess IV3-9/+14
A number of warnings still remain, but these were the last of the "unlexable code"-related ones (AFAICT). I changed a few examples in docs/UsersManual.rst to showcase -Wextra-tokens because it's already documented (-Wmultichar isn't), and the sphinx C lexer apparently can't handle char literals like 'ab'. It seemed like a better overall approach than just marking the code blocks as none or console. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@273232 91177308-0d34-0410-b5e6-96231b3b80d8

2016-06-14Add loop pragma for Loop DistributionAdam Nemet1-3/+35
Summary: This is similar to other loop pragmas like 'vectorize'. Currently it only has state values: distribute(enable) and distribute(disable). When one of these is specified the corresponding loop metadata is generated: !{!"llvm.loop.distribute.enable", i1 true/false} As a result, loop distribution will be attempted on the loop even if Loop Distribution in not enabled globally. Analogously, with 'disable' distribution can be turned off for an individual loop even when the pass is otherwise enabled. There are some slight differences compared to the existing loop pragmas. 1. There is no 'assume_safety' variant which makes its handling slightly different from 'vectorize'/'interleave'. 2. Unlike the existing loop pragmas, it does not have a corresponding numeric pragma like 'vectorize' -> 'vectorize_width'. So for the consistency checks in CheckForIncompatibleAttributes we don't need to check it against other pragmas. We just need to check for duplicates of the same pragma.

2016-05-27[mips] Compact branch policy setting.Simon Dardis1-0/+10
This patch adds the commandline option -mcompact-branches={never,optimal,always), which controls how LLVM generates compact branches for MIPSR6 targets. By default, the compact branch policy is 'optimal' where LLVM will generate the most appropriate branch for any situation. The 'never' and 'always' policy will disable or always generate compact branches wherever possible respectfully.

2016-05-23Clang support for __is_assignable intrinsicDavid Majnemer1-0/+1
MSVC now supports the __is_assignable type trait intrinsic, to enable easier and more efficient implementation of the Standard Library's is_assignable trait. As of Visual Studio 2015 Update 3, the VC Standard Library implementation uses the new intrinsic unconditionally. The implementation is pretty straightforward due to the previously existing is_nothrow_assignable and is_trivially_assignable. We handle __is_assignable via the same code as the other two except that we skip the extra checks for nothrow or triviality. Patch by Dave Bartolomeo!

2016-05-04[ASTMatchers] New matcher forFunctionGabor Horvath1-0/+14
Summary: Matcher proposed in the review of checker misc-assign-operator (name pending). Its goal is to find the direct enclosing function declaration of a statement and run the inner matcher on it. Two version is attached in this patch (thus it will not compile), to be decided which approach to take. The second one always chooses one single parent while the first one does a depth-first search upwards (thus a height-first search) and returns the first positive match of the inner matcher (thus it always returns zero or one matches, not more). Further questions: is it enough to implement it in-place, or ASTMatchersInternals or maybe ASTMatchFinder should be involved?
