@Dave Here comes the answer to if we can use -marm explained by jyasskin on #llvm "If you put a CallInst in your LLVM IR whose target is an llvm::Function, and that Function is an external declaration (i.e containing no BasicBlocks), then llvm will try to use dlsym() to look up the code for that

This is not a miscompile in the sense that the compiler's code generation is not wrong; but there is non-Thumb-2 compatible inline assembler, which means that the code may not work if the package is built in Thumb-2. The ldm ..., {...,lr,pc} instruction form is not permitted in Thumb-2. However, t
