We always want get_mask_mode return a valid mode, it's something wrong if it failed, so I think we could just move the `.require ()` into get_mask_mode, instead of calling that every call-site. The only exception is riscv_get_mask_mode, it might put supported mode into get_mask_mode, so added a check with riscv_v_ext_mode_p to make sure only valid vector mode will ask get_mask_mode. gcc/ChangeLog: * config/riscv/autovec.md (abs<mode>2): Remove `.require ()`. * config/riscv/riscv-protos.h (get_mask_mode): Update return type. * config/riscv/riscv-v.cc (rvv_builder::rvv_builder): Remove `.require ()`.

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.
