Hi, How to compile a large project (such as Apache) by using llvm-gcc? I tried to replace CC with llvm-gcc and CFLAGS with -emit-llvm while running configure, but it didn't work. Thank you for your help. -Wink

If, however, you want to do inter-procedural optimization or whole

Dear John, Thanks for your reply. I want to do whole program analysis, all what I need are just the separate .bc files. What instructions should I follow? I run the configure on apache in this way: CC=clang CFLAGS=-emit-llvm ./configure while I get the error message like: checking for gcc... clang checking for C compiler default output file name... configure: error: C compiler cannot

Hello, I have tried a lot fix this error but am not able to can you please find me a solution am trying to compile the SAFECode in Cygwin Environment to work for windows. used make -j4 command to make the files in cygwin i have got this error make[5]: Leaving directory '/home/uidr7475/Work/LLVM_OBJ/projects/safecode/tools/clang/include' /usr/bin/cp: cannot stat

Hi All, After the initial learning curve, we're excited to have put together a completely gcc/binutils-free toolchain based on LLVM. Now that we have things working, we desperately need to optimize the resulting binaries. Our bin files are up to 10x their fully optimized gcc equivalent (1.5k vs 16k). This is for a bare metal ARM based system so this is significant. We're using lld for

So in the end the gold plugin wouldn't

Whole-program analysis requires that you link all of the individual bitcode files from different compilation unit (i.e., individual .c files) together into a single

Thank you. But now I am using LLVM 2.9, so which version of poolalloc I should use ? -------------------------------------------- Qiuping Yi Institute Of Software Chinese Academy of Sciences On Fri, Jan 30, 2015 at 11:12 PM, John Criswell <jtcriswel at gmail.com> wrote: > Dear Qiuping, > > If you use the release_32 branch of poolalloc, then you need to use LLVM > 3.2. >

Hi, all I want to use the alias analysises in project poolalloc, but I encounter some problem during installing it. I install poolalloc as follow: 1) cd llvm/projects svn co http://llvm.org/svn/llvm-project/poolalloc/branches/release_32 poolalloc 3) cd LLVM-object-directory make tools-only cd projects/poolalloc make When I carried out "make", I get the next error

I tried to compare two types. Because of renaming, the comparison result is not as expected. How to deal with renaming while comparing types?

Hi, John Criswell Thank you very much. I am installing LLVM-3.2, but I encounter the next error when carrying out "make": llvm[3]: Compiling ClangASTNodesEmitter.cpp for Release+Asserts build ClangASTNodesEmitter.cpp: In member function ‘std::pair<llvm::Record*, llvm::Record*><unnamed>::ClangASTNodesEmitter::EmitNode(const std::multimap<llvm::Record*, llvm::Record*,

Hi Mehdi, Thanks for your reply. It seems caused by random rename because I saw %struct.StructTyName.692.475*, which might be twice renaming. Does this collision occur because this type is declared more than once? I encountered this problem when used clang to compile transmission 1.42 (http://download.transmissionbt.com/files/) with configuration: "./configure --disable-gtk". Then

Dear Pawel and All, Pawel (and other release managers), can you ask the project maintainers for each project whether they want a release branch before creating it next time? Alternatively, can you leave branch creation up to the project maintainers as in the past? Pawel, you created a release_32 branch of SAFECode last night without my consultation. That commit itself is fine since we just

Oh, got it. Thanks for your explain. I misunderstand what getLocation does. If I would like to get the result of alias analysis referring to the stored value, what should I do in llvm?

Hi All, It seems that functions in callgraph remove all metadata info, such as dbg. Can I keep metadata in callgraph? Best, Haopeng
