- New option -misa-spec support: -misa-spec=[2.2|20190608|20191213] and corresponding configuration option --with-isa-spec. - Current default ISA spec set to 2.2, but we intend to bump this to 20191213 or later in next release. gcc/ChangeLog: * common/config/riscv/riscv-common.c (riscv_ext_version): New. (riscv_ext_version_table): Ditto. (get_default_version): Ditto. (riscv_subset_t::implied_p): New field. (riscv_subset_t::riscv_subset_t): Init implied_p. (riscv_subset_list::add): New. (riscv_subset_list::handle_implied_ext): Pass riscv_subset_t instead of separated argument. (riscv_subset_list::to_string): Handle zifencei and zicsr, and omit version if version is unknown. (riscv_subset_list::parsing_subset_version): New argument `ext`, remove default_major_version and default_minor_version, get default version info via get_default_version. (riscv_subset_list::parse_std_ext): Update argument for parsing_subset_version calls. Handle 2.2 ISA spec, always enable zicsr and zifencei, they are included in baseline ISA in that time. (riscv_subset_list::parse_multiletter_ext): Update argument for `parsing_subset_version` and `add` calls. (riscv_subset_list::parse): Adjust argument for riscv_subset_list::handle_implied_ext call. * config.gcc (riscv*-*-*): Handle --with-isa-spec=. * config.in (HAVE_AS_MISA_SPEC): New. (HAVE_AS_MARCH_ZIFENCEI): Ditto. * config/riscv/riscv-opts.h (riscv_isa_spec_class): New. (riscv_isa_spec): Ditto. * config/riscv/riscv.h (HAVE_AS_MISA_SPEC): New. (ASM_SPEC): Pass -misa-spec if gas supported. * config/riscv/riscv.opt (riscv_isa_spec_class) New. * configure.ac (HAVE_AS_MARCH_ZIFENCEI): New test. (HAVE_AS_MISA_SPEC): Ditto. * configure: Regen. gcc/testsuite/ChangeLog: * gcc.target/riscv/arch-9.c: New. * gcc.target/riscv/arch-10.c: Ditto. * gcc.target/riscv/arch-11.c: Ditto. * gcc.target/riscv/attribute-6.c: Remove, we don't support G with version anymore. * gcc.target/riscv/attribute-8.c: Reorder arch string to fit canonical ordering. * gcc.target/riscv/attribute-9.c: We don't emit version for unknown extensions now. * gcc.target/riscv/attribute-11.c: Add -misa-spec=2.2 flags. * gcc.target/riscv/attribute-12.c: Ditto. * gcc.target/riscv/attribute-13.c: Ditto. * gcc.target/riscv/attribute-14.c: Ditto. * gcc.target/riscv/attribute-15.c: New. * gcc.target/riscv/attribute-16.c: Ditto. * gcc.target/riscv/attribute-17.c: Ditto. |

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.
