2012-11-10Add clang support of RTM from TSXMichael Liao
- New options '-mrtm'/'-mno-rtm' are added to enable/disable RTM feature - Builtin macro '__RTM__' is defined if RTM feature is enabled - RTM intrinsic header is added and introduces 3 new intrinsics, namely '_xbegin', '_xend', and '_xabort'. - 3 new builtins are added to keep compatible with gcc, namely '__builtin_ia32_xbegin', '__builtin_ia32_xend', and '__builtin_ia32_xabort'. - Test cases for pre-defined macro and new intrinsic codegen are added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167665 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-10Revert "Disable -Wimplicit-fallthrough when not using C++.", pending further ↵Ted Kremenek
discussion on cfe-dev. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167662 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-10Disable -Wimplicit-fallthrough when not using C++.Ted Kremenek
The rationale is that there is no good workflow to silence the warning for specific cases, other than using pragmas. This is because the attribute to decorate an explicit fall through is only available in C++11. By that argument, this should probably also be disabled unless one is using C++11, but apparently there is an explicit test case for this warning when using C++98. This will require further discussion on cfe-commits. Fixes: <rdar://problem/12584746> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167655 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-10[analyzer] When invalidating symbolic offset regions, take fields into account.Jordan Rose
Previously, RegionStore was being VERY conservative in saying that because p[i].x and p[i].y have a concrete base region of 'p', they might overlap. Now, we check the chain of fields back up to the base object and check if they match. This only kicks in when dealing with symbolic offset regions because RegionStore's "base+offset" representation of concrete offset regions loses all information about fields. In cases where all offsets are concrete (s.x and s.y), RegionStore will already do the right thing, but mixing concrete and symbolic offsets can cause bindings to be invalidated that are known to not overlap (e.g. p[0].x and p[i].y). This additional refinement is tracked by <rdar://problem/12676180>. <rdar://problem/12530149> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167654 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-10PR14296: function parameter name collisions in function try/catchDavid Blaikie
C++11 3.3.3/2 "A parameter name shall not be redeclared in the outermost block of the function definition nor in the outermost block of any handler associated with a function-try-block." It's not totally clear to me whether the "FIXME" case is covered by this, but Richard Smith thinks it probably should be. It's just a bit more involved to fix that case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167650 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-09Improved support for removing the comma preceding __VA_ARGS__ where __VA_ARGS__Andy Gibbs

This fixes a divergence in support for the ", ## __VA_ARGS__" GCC extension which differed in behaviour when in strict C99 mode (note: there is no change in behaviour has been made in the gnu99 mode that clang uses by default). In addition, there is improved support for the Microsoft alternative extension ", __VA_ARGS__". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167613 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-08Fix a bug I found while preparing my devmtg talk: When passing NULL to aMatt Beaumont-Gay
function that takes a const Foo&, where Foo is convertible from a large number of pointer types, we print ALL the overloads, no matter the setting of -fshow-overloads.
