Subject: target/riscv: Relax vector register check in RISCV gdbstub
X-Git-Tag: v9.1.0-rc0~87^2~15
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4a90991234f003d8fe55919e84bf3ec7d542830e;p=thirdparty%2Fqemu.git

target/riscv: Relax vector register check in RISCV gdbstub

In current implementation, the gdbstub allows reading vector registers
only if V extension is supported. However, all vector extensions and
vector crypto extensions have the vector registers and they all depend
on Zve32x. The gdbstub should check for Zve32x instead.
