| X86/COFF-Dependent |
| ------------------ |
| |
| The following additional relocation type is supported: |
| |
| **@IMGREL** (AT&T syntax only) generates an image-relative relocation that |
| corresponds to the COFF relocation types ``IMAGE_REL_I386_DIR32NB`` (32-bit) or |
| ``IMAGE_REL_AMD64_ADDR32NB`` (64-bit). |

| fun: |
| mov foo@IMGREL(%ebx, %ecx, 4), %eax |
| |
| .section .pdata |
| .long fun@IMGREL |
| .long (fun@imgrel + 0x3F) |
| .long $unwind$fun@imgrel |
