I have the following macro to embed a file in my code and it works just fine:

.macro add_resource resource_name, file_name
    .global resource_name
    .type resource_name, @object
    .balign 4
resource_name:
    .incbin "file_name"
end_resource_name:
    .global size_resource_name
    .type size_resource_name, @object
    .balign 4
size_resource_name:
    .int end_resource_name - resource_name
.endm

.section .rodata

add_resource icon, "icon.png"

and the usage:

#include <stdio.h>
extern unsigned char icon[];
extern unsigned int size_icon;
int main() {
    printf("magic bytes: %.3s, size: %u", icon+1, size_icon);
    return 0;
}

which prints “magic bytes: PNG, size: 16350077”. But the name “size_icon” looks awful, i want to append the “size”, instead of prepending it, which would make it “icon_size”. But i don’t know how to do that. Can anyone help?
