Motivation

I'm learning how to use and write my own linker scripts.

The problem

Currently, I have 2 simple functions in a .c file and I'd like to put each of those functions in separate sections, but I couldn't found out how to "access" those functions in the linker script.

Reproduction steps

Those two files are all in the same directory:

file1.c

int func1() {
    return 10;
}

char * func3() {
    return (void *) 0;
}

linker.ld

SECTIONS {
    .text 0xDEADBEEF : {
        file1.o (.text.func1)
    }

    .data 0x4 : {
        file1.o (.text.func3)
    }
}

Now do the following:

gcc -c file1.c
ld -T linker.ld file1.o

Expected/Desired output

What I expect to get from objdump -d a.out:

a.out:     file format elf64-x86-64


Disassembly of section .text:

00000000deadbeef <func1>:
    deadbeef:   55                      push   %rbp
    deadbef0:   48 89 e5                mov    %rsp,%rbp
    deadbef3:   b8 0a 00 00 00          mov    $0xa,
