RISC-V has provide different VLEN configuration by different ISA extension like `zve32x`, `zve64x` and `v` zve32x just guarantee the minimal VLEN is 32 bits, zve64x guarantee the minimal VLEN is 64 bits, and v guarantee the minimal VLEN is 128 bits, Current status (without this patch): Zve32x: Mode for one vector register mode is VNx1SImode and VNx1DImode is invalid mode - one vector register could hold 1 + 1x SImode where x is 0~n, so it might hold just one SI Zve64x: Mode for one vector register mode is VNx1DImode or VNx2SImode - one vector register could hold 1 + 1x DImode where x is 0~n, so it might hold just one DI. - one vector register could hold 2 + 2x SImode where x is 0~n, so it might hold just two SI. However `v` extension guarantees the minimal VLEN is 128 bits. We introduce another type/mode mapping for this configure: v: Mode for one vector register mode is VNx2DImode or VNx4SImode - one vector register could hold 2 + 2x DImode where x is 0~n, so it will hold at least two DI - one vector register could hold 4 + 4x SImode where x is 0~n, so it will hold at least four DI This patch model the mode more precisely for the RVV, and help some middle-end optimization that assume number of element must be a multiple of two. gcc/ChangeLog: * config/riscv/riscv-modes.def (FLOAT_MODE): Add chunk 128 support.

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.
