[BUG FIX] RISC-V: Disallow COSNT_VECTOR for DI on RV32

2023-11-21 Thread Juzhe-Zhong

This bug is exposed when testing on zvl512b RV32 system. The rootcause is RA reload DI CONST_VECTOR into vmv.v.x then it ICE. So disallow DI CONST_VECTOR on RV32. PR target/112598 gcc/ChangeLog: * config/riscv/riscv.cc (riscv_const_insns): Disallow DI CONST_VECTOR on RV32.
