About
Landing pad (Zicfilp) is an ISA extension for protecting control-flow integrity and is a sibling spec of shadow stack (Zicfiss).
RISC-V ARC (Architecture Review Committee) has approved the latest draft (v0.4.0) of Zicfilp spec. Now it requires SW implementations.
In addition to MediaTek that has demand for LLVM support, it looks that the community, including SiFive and Rivos, are also working on it.
RISE will be a great venue for collaboration.
