Missing support for `R_X86_64_GOTPCRELX` and `R_X86_64_REX_GOTPCRELX`

[Lukasdoe]

When compiling for AOT on a Intel Xeon Gold 6430, Ubuntu 24.04.2 LTS x86_64 host, I get the runtime error "Load relocation section failed: invalid relocation type 42."

Subject of the issue

Relocation types R_X86_64_GOTPCRELX (= 41) and R_X86_64_REX_GOTPCRELX (= 42) are not supported in aot_reloc_x86_64.c.

Your environment

• OS: Ubuntu 24.04.2 LTS x86_64
• Host: PowerEdge R760
• Kernel: 6.8.0-60-generic
• CPU: Intel Xeon Gold 6430 (64) @ 3.400GHz
• WAMR / IWASM: 2.3.1

Steps to reproduce

wamrc -o test.aot test.wasm
iwasm ./test.aot

Expected behavior

That is runs.

Actual behavior

It aborts execution with the runtime error.

I will take a look at this

Hi, @Lukasdoe could you try my branch https://github.com/TianlongLiang/wasm-micro-runtime/tree/dev/aot_new_reloc and see whether it fixes it?

This fixes the problem on my side! Thank you :)
