Akira Hatanaka ba0367a708 [CodeGen][ObjC] Build the global block structure before emitting the body of global block invoke functions. This commit fixes an infinite loop in IRGen that occurs when compiling the following code: void FUNC2() { static void (^const block1)(int) = ^(int a){ if (a--) block1(a); }; } This is how IRGen gets stuck in the infinite loop: 1. GenerateBlockFunction is called to emit the body of "block1". 2. GetAddrOfGlobalBlock is called to get the address of "block1". The function calls getAddrOfGlobalBlockIfEmitted to check whether the global block has been emitted. If it hasn't been emitted, it then tries to emit the body of the block function by calling GenerateBlockFunction, which goes back to step 1. This commit prevents the inifinite loop by building the global block in GenerateBlockFunction before emitting the body of the block function. rdar://problem/34541684 Differential Revision: https://reviews.llvm.org/D38118 llvm-svn: 314029		2017-09-22 21:32:06 +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
