...r LLVM codebase to detect false-positives and at the same time eliminate memory leaks. The majority of leaks were detected in lib/Target/* and lib/MC/*. In all cases the similar trick was detected as a leak (example from lib/Target/Sparc/MCTargetDesc/SparcMCTargetDesc.cpp) : static MCStreamer *createMCStreamer(const Target &T, StringRef TT, MCContext &Context, MCAsmBackend &MAB, raw_ostream &OS, MCCodeEmitter *Emitter, const MCSubtargetInfo &STI, bool RelaxAll,...

Hello, We're currently working on MC-JIT, focusing on runtime generation and loading of ELF object files, even on non-ELF platforms (i.e. Windows). However, we run into a problem with MC insisting to generate COFF objects on Windows, MachO on Macs and ELF only otherwise, based on the triple. Is there an existing method to generate ELF objects with MC on Windows, without modifying MC? Thanks

I am having an issue with MCJIT on the ppc64 machine architecture. The symptom is that for a particular IR function the target machine won't emit neither an object nor an assembly file and subsequent calling the pointer to function results in a segfault. My application generates on the fly several functions with the builder and executes them with the MCJIT engine. I came across this
