[wojiushixiaobai]

Version

v22.12.0

Platform

Linux debian 6.1.0-27-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.115-1 (2024-11-01) x86_64 GNU/Linux

Subsystem

Cross-compiling for Linux loongarch64 on a Linux x86_64 machine.

What steps will reproduce the bug?

How often does it reproduce? Is there a required condition?

always

What is the expected behavior? Why is that the expected behavior?

Should compile.

What do you see instead?

Sorry about that!

Fix undefined reference to 'v8_internal_simulator_ProbeMemory'
#56466

The loongarch64-clfs-7.3-cross-tools-gcc-glibc.tar.xz compilation toolchain used does not support LSX/LASX yet.
We may need to upgrade the toolchain to Binutils (>=2.41) and GCC (>=14.1.0)
