Checklist

Describe your issue

In this example, the LoongArch compiler generates an R_LARCH_64_PCREL relocation for 1b - .. Unfortunately, older binutils linker does not support R_LARCH_64_PCREL and merely issue a warning instead of failing, leading to incorrect values in the linked executable.

fn main() {
    unsafe {
        core::arch::asm!(
            r#"
            1:
            nop
            .pushsection jump_table,  "awR"
            .balign 8
            .quad 1b - .
            .popsection
            "#
        );
    }
}
