NOCROSSREFS in linker script?

NOCROSSREFS is a linker script command that is used to prevent the linker from creating cross-references between specific sections. When the linker creates an executable or shared library, it may need to resolve references between different sections of code or data. However, in some cases, it may be desirable to prevent the linker from creating cross-references between certain sections for performance or other reasons.

The NOCROSSREFS command is used in a linker script to specify that the linker should not create cross-references between the specified sections. This can be useful when certain sections are known to be self-contained and do not need to reference other sections, or when certain sections have already been linked together and should not be linked again.

Here's an example of how the NOCROSSREFS command can be used in a linker script:

SECTIONS {
  .text : {
    *(.text)
    *(.rodata)
    *(.data)
    NOCROSSREFS { *(.special_section) }
  }
}

In this example, the linker will link together the .text, .rodata, and .data sections as usual, but will not create cross-references to the .special_section.
