Hi, Encounter a compilation issue related to c++. Software versions: - gcc 4.7.4 - llvm git commit 98a1ca117e6743dd7f2d505443a96f591d083eab Build log: Scanning dependencies of target LLVMLTO [ 53%] Building CXX object lib/LTO/CMakeFiles/LLVMLTO.dir/Caching.cpp.o /tmp/pkgs/llvm/lib/LTO/Caching.cpp: In lambda function: /tmp/pkgs/llvm/lib/LTO/Caching.cpp:74:7: error: looser throw specifier for 'virtual llvm::lto::localCache(std::string, llvm::lto::AddFileFn)::<lambda(unsigned int,...

...h means if you change core libraries and do a rebuild, things like tools/lto don't get relinked against the new libraries. Test case is to have a pre-built tree and do "touch lib/System/Unix/ Program.inc && make" and make sure you see "Linking Debug Loadable Module LLVMlto.dylib". 3) There appears to be a typo for for llvm_cv_no_link_all_option for Darwin, but this never seems to be used anyway. Probably worth fixing in case a new standalone project uses the LLVM makefiles. I regenerated the configure script with the required versions of autotools on Mac...

...ve bitcode only ) linking? Or - Future changes to lib/Object will implement llvm module linking for me? I suspect you meant the first. If so, is the intention that if someone needs to link an in memory LLVM bitcode module to an archive of bitcode modules ( produced by the new llvm-ar or at with llvmLTO wrapper to ar) then they should use the API of lld? Does that API exist now? I took a look at the lld source code and I couldn't find any methods that returned llvm::Module so I assumed it wasn't possible. Thanks, Dan Liew -------------- next part -------------- An HTML attachment was scru...

Trying to run a self host "ninja check-clang" with ASan enabled I hit a /lot/ of errors like this (strangely I hit none of these in check-llvm, only in check-clang): Any ideas? ==10525==ERROR: AddressSanitizer failed to deallocate 0x10800 (67584) bytes at address 0x631000014800 ==10525==AddressSanitizer CHECK failed:
