From: Lino Hsing-Yu Peng <[email protected]>
Add initial ISA-level for Zvfofp8min extension.
gcc/ChangeLog:
* common/config/riscv/riscv-common.cc: Add zvfofp8min support.
* config/riscv/riscv-ext.def: Add zvfofp8min entry.
* config/riscv/riscv-ext.opt: Add zvfofp8min option.
* config/riscv/riscv-vector-builtins.cc: Require zvfofp8min.
* config/riscv/riscv-vector-builtins.h: Add zvfofp8min handling.
* doc/riscv-ext.texi: Document the new extension.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/arch-61.c: New test.
