Simon Pilgrim 12919f7e49 [X86][SSE] Replace 128-bit SSE41 PMOVSX intrinsics with native IR 
128-bit vector integer sign extensions correctly lower to the pmovsx instructions even for debug builds.

This patch removes the builtins and reimplements the _mm_cvtepi*_epi* intrinsics __using builtin_shufflevector (to extract the bottom most subvector) and __builtin_convertvector (to actually perform the sign extension).

unittests Rename AST node matchers to match the AST node names directly. Part of this rename also splits recordDecl() (which used to match CXXRecordDecl) into recordDecl() (that matches RecordDecl) and cxxRecordDecl (that matches CXXRecordDecl). Also adds isStruct(), isUnion(), and isClass() narrowing matchers for RecordDecl objects. 2015-09-17 13:30:52 +00:00

//===----------------------------------------------------------------------===//
// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

Information on Clang:              http://clang.llvm.org/

Clang Static Analyzer:             http://clang-analyzer.llvm.org/

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:

If you find a bug in Clang, please file it in the LLVM bug tracker:
