From b8891f8d622a31306062065813fc278d8a94fe21 Mon Sep 17 00:00:00 2001 From: Andrew Jenner Date: Mon, 30 Jul 2018 12:24:14 +0100 Subject: Add support for the C_SKY series of processors. This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc. This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about. bfd * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add C-SKY.
