2017-10-20Add generic part for Intel CET enabling. The spec is available atIgor Tsimbalist1-4/+2
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf A proposal is to introduce a target independent flag -fcf-protection=[none|branch|return|full] with a semantic to instrument a code to control validness or integrity of control-flow transfers using jump and call instructions. The main goal is to detect and block a possible malware execution through transfer the execution to unknown target address. Implementation could be either software or target based. Any target platforms can provide their implementation for instrumentation under this option. The compiler should instrument any control-flow transfer points in a program (ex. call/jmp/ret) as well as any landing pads, which are targets of control-flow transfers. A new 'nocf_check' attribute is introduced to provide hand tuning support. The attribute directs the compiler to skip a call to a function and a function's landing pad from instrumentation. The attribute can be used for function and pointer to function types, otherwise it will be ignored. Currently all platforms except i386 will report the error and do no instrumentation. i386 will provide the implementation based on a specification published by Intel for a new technology called Control-flow Enforcement Technology (CET). gcc/c-family/ * c-attribs.c (handle_nocf_check_attribute): New function.
