525a0aa301 CSKY: Add new arches while refine the cpu option process.
Add arches CK804, CK805 and CK800. CK800 is an special arch which
support all instructions for CSKYV2. Refine the cpu tables to
simplify adding a new cpu.

fe0e921f00 PR26513, 629310abec breaks assembling PowerPC Linux kernels
Inserting with replacement is wrong for some gas hash table uses.
This patch implements an htab_insert that conditionally replaces, and
similarly for str_hash_insert.  str_hash_insert with replace=0 is
roughly equivalent to the older hash_insert, and str_hash_insert with
replace=1 to the older hash_jam, but return values are different.  I
found it useful to know whether the slot was occupied prior to
inserting/replacing.  I've also reinstated the fatal errors on messing
up opcode tables with duplicates.

a39d29cda1 gas: Update fr_literal access in frag for GCC 10
When access fr_literal in

struct frag {
  ...
  /* Data begins here.  */
  char fr_literal[1];
};

with

char *buf = fragp->fr_fix + fragp->fr_literal;

GCC 10 gave

gas/config/tc-csky.c: In function ‘md_convert_frag’:
gas/config/tc-csky.c:4507:9: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]
 4507 |  buf[1] = BYTE_1 (CSKYV1_INST_SUBI | (7 << 4));
      |         ^

Change

  char *buf = fragp->fr_fix + fragp->fr_literal;

to

  char *buf = fragp->fr_fix + &fragp->fr_literal[0];

to silence GCC 10 warning.

	* config/tc-csky.c (md_convert_frag): Replace fragp->fr_literal

8d1015a887 Move struc-symbol.h to symbols.c
This file was never supposed to be widely used.  The fact that it has
found its way into many gas files led to bugs, typically when code
expecting a symbolS* to point at a struct symbol is presented with a
struct local_symbol.  Also, commit 158184ac9e changed these structs in
2012 but didn't catch all places where symbol bsym was being used to
test for a local_symbol.

b8891f8d62 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.
