LLVM compiler for production code?

Several questions asked here, I'll try to answer all of them.

Several questions asked here, I'll try to answer all of them. There is no "pure LLVM compiler". LLVM is a set of libraries which do code optimization and code generation .

There are several C/C++ frontends which can be hooked to LLVM. Among them are clang and llvm-gcc. See llvm.org/ for more information about various components of LLVM Compiler Infrastructure.As written at llvm.org/docs/ReleaseNotes.

Html, llvm-gcc is EOL since LLVM 2.9 release, so you'd better use clang, because it will certainly be developed and maintained in the future. Libc++ is still in development, so for production you should use vendor-provided C++ (libstdc++ in your case).

Testing by a wider audience might help to obtain "production-ready" tag quite fast though. – Anton Korobeynikov Apr 8 at 18:15.

Remember, all this stuff is changing, so benchmarks gets easily outdated. I've found following report interesting, not only as a kind of benchmark, but it seems showing some LLVM vs GCC compiler differences : Clang/LLVM Maturity Evaluation Report by Dominic Fandrey.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
