This patch adds a string attribute to each function which enables GC codegen and selects the metadata format to generate. In order to avoid adding a word to each Function for programs which do not use garbage collection (e.g. llvm-gcc, clang), this value is stored in an on-the- side table. — Gordon gc-5a-funattr.patch (+222 -22): docs/LangRef.html (+22 -3)

After cloning a Module with CloneModule, there doesn't seem to be any easy way to convert a Value pointing into the old Module to a Value pointing into the new one. The CloneModule implementation already has to keep such a mapping internally, so I've written a patch that exposes it as a second inout parameter to CloneModule(), with the one param version being a simple wrapper for backward

Hi I am not a good programmer but for my project i have to use llvm to generate CFG for c programs where i have a mapping from IR instruction in CFG to their respective c instruction. After surfing a in source of llvm i did the following change in printInstruction() function in llvm/lib/VMCore/AsmWriter.cpp file. .....void AssemblyWriter::printInstruction(const Instruction &I) { if

Good day Nathan, If your using the stock GCC with Solaris, I am sorry to inform you its broken, Please see: http://llvm.org/docs/GettingStarted.html#brokengcc Please be warned as your get miss compiles and things will do strange `stuff`. As can be seen here, the reverse is true for both the GNU binutils and XPG4 versions of `nm' : -bash-3.2$ /usr/xpg4/bin/nm -p -u `find . -name

Hi, I found the following bug in llvm::CloneModule (svn, head revision). When copying over global variables the address space is reset to default. The patch changes that behavior by using the other GlobalVariable constructor that explicitely includes that information.

Hi Gregory, I had a similar problem a while back, see: http://lists.cs.uiuc.edu/pipermail/llvmdev/2010-June/032508.html for my solution to this problem. Basically I ended up linking in the *.o files needed to get exactly what I needed (in your case, the file defining CloneModule and whatever else you need), without pulling in too much (causing duplicate symbol issues with opt). Hopefully this

Sorry if this has been discussed already... I am trying to understand whether there is an underlying reason why llvm::CloneModule takes argument function ShouldCloneDefinition to discriminate on objects being cloned, but blindly copies all named metadata...? In my case this results in debug nodes that are creating uses/relocations for global objects that were _not_ copied per

I just updated my llvm sources (revision 164794.) and I see the error, "overriding non-deleted function" when building with gcc 4.7.0 and passing -std=c++11. /usr2/sidneym/llvm/tools/install/bin/c++ -D_GNU_SOURCE -D_DEBUG -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -std=c++11 -fPIC -fvisibility-inlines-hidden -I/local/scratch/llvm-tmp/build/lib/VMCore
