[LLVMdev] Current status of ARM backend (system-level support specifically) on LLVM?
Hello all, We just started to look at how we could use LLVM to secure ARM-based mobile system from malware like overriding pointers to system functions and causing memory overflow. I'm wondering how the current ARM backend work on the current LLVM release. Does it have any support for ARM system-level instructions to change the page tables or switching tasks? I appreciate your help and comment. Regards, Won -------------- next part -------------- An HTML attachment was scrubbed...
