Subject: RISC-V: Reflect actual range of vlen for hashing
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=86dfe011797b3e442622d427e9abd1e0f70f3a62;p=binutils-gdb.git

RISC-V: Reflect actual range of vlen for hashing

Before actual vlen handling, fix the riscv_gdbarch_features hashing
function based on the actual valid range of vlen.  In bytes, vlen is 0,
or 4 <= xlen <= 8192.
