From: SiYu Wu <s...@isrc.iscas.ac.cn> This patch add gcc backend support for RISC-V Scalar Cryptography Extension (k-ext), including machine description, builtins defines and testcases for each k-ext's subset.
A note about Zbkx: The Zbkx should be implemented in bitmanip's Zbp, but since zbp is not included in the bitmanip spec v1.0, and crypto's v1.0 release will earlier than bitmanip's next release, so for now we implementing it here. Version logs: v2: As Kito mentions, now this patch only includes the arch string related stuff, the builtins and md changes is not included, waiting for the builtin and intrinsic added to the spec. Also removed the unnecessary patches and add Changelogs.
