Kito Cheng 09baee1ab1 RISC-V: Add RV32E support. 
Kito Cheng <kito.cheng@gmail.com>
	Monk Chiang  <sh.chiang04@gmail.com>

	gcc/
	* common/config/riscv/riscv-common.c (riscv_parse_arch_string):
	Add support to parse rv32e*.  Clear MASK_RVE for rv32i and rv64i.
	* config.gcc (riscv*-*-*): Add support for rv32e* and ilp32e.
	* config/riscv/riscv-c.c (riscv_cpu_cpp_builtins): Define
	__riscv_32e when TARGET_RVE.  Handle ABI_ILP32E as soft-float ABI.
	* config/riscv/riscv-opts.h (riscv_abi_type): Add ABI_ILP32E.
	* config/riscv/riscv.c (riscv_compute_frame_info): When TARGET_RVE,
	compute save_libcall_adjustment properly.
	(riscv_option_override): Call error if TARGET_RVE and not ABI_ILP32E.
	(riscv_conditional_register_usage): Handle TARGET_RVE and ABI_ILP32E.
	* config/riscv/riscv.h (UNITS_PER_FP_ARG): Handle ABI_ILP32E.
	(STACK_BOUNDARY, ABI_STACK_BOUNDARY): Handle TARGET_RVE.
	(GP_REG_LAST, MAX_ARGS_IN_REGISTERS): Likewise.
	(ABI_SPEC): Handle mabi=ilp32e.
	* config/riscv/riscv.opt (abi_type): Add ABI_ILP32E.
	(RVE): Add RVE mask.
	* doc/invoke.texi (RISC-V options) <-mabi>: Add ilp32e info.
	<-march>: Add rv32e as an example.

	gcc/testsuite/
	* gcc.dg/stack-usage-1.c: Add support for rv32e.

	libgcc/
	* config/riscv/save-restore.S: Add support for rv32e.

README 

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
