Lenoids opened a new pull request, #20111:
URL: https://github.com/apache/nuttx/pull/20111
## Summary
Fix a build failure when `CONFIG_ARCH_RV_ISA_V=y` and
`CONFIG_ARCH_RV_VECTOR_BYTE_LENGTH=0`.
`vregs` belongs to `struct xcptcontext`, not `struct tcb_s`.
## Impact
Cause a build failure.
## Testing
ostest passed on QEMU 8.2.10.
- Host: Ubuntu 20.04.6 LTS, x86_64
- Toolchain: xPack RISC-V Embedded GCC 15.2.0
- Board configuration: `rv-virt:smp64`
- Emulator: QEMU 8.2.10
Configuration:
```text
CONFIG_ARCH_RV_ISA_V=y
CONFIG_ARCH_RV_VECTOR_BYTE_LENGTH=0
CONFIG_SMP_NCPUS=8
```
