Manman Ren 2738278b7f [i386 ABI] expand small C like structs in C++, just like how we handle small C structs. This comes up when we have a function that takes a struct and is defined in a C++ file and used in a C file. Before this commit, we will generate byval for C++ and will expand the struct for C, thus causing difference at IR level. We will use bitcast of function type at the callsite, which causes the inliner to not inline the function. This commit changes how we handle small C like structs at IR level, but at backend, we should generate the same argument passing before and after the commit. Note that the condition for expanding is still over conservative. We should be able to expand type that is spelled with “class” and types that are not C-like. But this commit fixes the inconsistent argument passing between C/C++. Reviewed by John. rdar://20121030 llvm-svn: 234033		2015-04-03 18:10:29 +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:

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