[1/1] RISC-V: Imply 'Zicsr' from 'Zcmt'

  From: Tsukasa OI <research_trasio@irq.a4lg.com>

As the specification states, the 'Zcmt' extension depends on the 'Zca' and
'Zicsr' extensions.  This commit reflects this implication.

gcc/ChangeLog:

	* common/config/riscv/riscv-common.cc
	(riscv_implied_info): Add implication from 'Zcmt' to 'Zicsr'.

LGTM, did you have commit access for GCC repo? you should obtain it if
you don't have it yet, I think you are already an important member of
the RISC-V GNU toolchain community :)

https://gcc.gnu.org/gitwrite.html#authenticated , and you can add me
to the cc list as your sponsor.

Not yet (only Binutils/GDB).  Jeff is mainly merging my changes to the
trunk so far.

Thanks for mentioning and sponsoring me for write access to GCC.  I
truly appreciate that mentioning me as an important member and write
access to the GCC repository will be also helpful.

I'll contact GCC overseers later.

Sincerely,
Tsukasa

Hi Tsukasa:

I guess you might did something wrong during commit this patch and
"RISC-V: Add stub support for existing extensions"

It's fine.  That patch was a part of "RISC-V: Add stub support for
existing extensions" (the only intent for subset submission was faster
review but the bigger one is accepted earlier than I expected).

Tsukasa
  

Ok, I just went through the patchlist and found this patch seems
not committed yet, anyway I will mark this as commit now :)
