Hi LLVM developers, As PR35281 mentioned: $ llvm-objcopy -O binary llvm-cortex-m7.elf llvm-cortex-m7.bin llvm-objcopy: 'llvm-cortex-m7.elf': The file was not recognized as a valid object file. if (ELFObjectFile<ELF64LE> *o = dyn_cast<ELFObjectFile<ELF64LE>>(&Binary)) https://github.com/llvm-mirror/llvm/blob/master/tools/llvm-objcopy/llvm-objcopy.cpp#L200

Hi David, This is really cool. I'd love to get this in-tree. There are two ways we could go about this: (1) Make the OrcArchitecture interface ABI-aware so that it can choose the right resolver code, or (2) Replace the OrcArchitecture classes with OrcABI classes. I.e. We'd just a rename OrcX86_64 -> Orc_X86_64_SysV (and rename I386 & AArch64 similarly) , then we add your code as

TargetMachine::addPassesToEmitFile(..) requires as its 2nd argument an raw_pwrite_stream. Is it possible to create such a thing which either writes into a standard string or streams to outs() ? Thanks,

Currently a power failure or other hard crash can cause lld leave a temporary file around. The same is true for other llvm tools. As an example, put a breakpoint in Writer.cpp:236 ("writeBuildId()") and restart the run a few times. You will get t.tmp43a735a t.tmp4deeabb t.tmp9bacdd3 t.tmpe4115c4 t.tmpeb01fff The same would happen if there was a fatal error between the
