Hi everyone, In llvm 4.0 the MCJIT::getFunctionAddress function return 0 (a null address) when the symbol is not found : *uint64_t MCJIT::getSymbolAddress(const std::string &Name, bool CheckFunctionsOnly) { std::string MangledName; { raw_string_ostream MangledNameStream(MangledName); Mangler::getNameWithPrefix(MangledNameStream, Name, getDataLayout()); } return findSymbol(MangledName, CheckFunctionsOnly).getAddress();}* Now with the current implementation (llvm 5.0 rc1 tag) : *uint64_t MCJIT::getSymb...

I've built chromium with " -fprofile-instr-generate -fsanitize=address" -- the performance looks good! The file format from r198638 is indeed rudimentary. Do you already know how the real output format will look like? Just to summarize what I think is important: - minimal size on disk, minimal amount of files - minimal i/o while writing to disk, no lockf or some such -

Hi, I think ExecutionEngine as a common interface for both Interpreter and MCJIT is almost useless in the current form. There are separated methods in ExecutionEngine for similar or the same features provided by Interpreter and MCJIT, i.e. to get a pointer to function you should call getPointerToFunction() for Interpreter or getFunctionAddress() for MCJIT. Personally, I'm using MCJIT and

Hello, I am doing some program analysis with C++ programs. I need to check if some particular function is called in the program, for that I need the name of the function being called in the call instruction. Since C++ mangles the name of the function, I need a way to demangle the function name in llvm IR. Is there any way to achieve that in llvm pass? Regards, Sangeeta -------------- next part

Dear all, trying to build some Heimdal-based packages for Samba AD DC under openSUSE I am facing some difficulties with the build system: During the installation which is triggered by "make install" waf complains about some task dependency cycle after leaving folder bin/default.
