<div>
<pre>When use newer version(>=9) of ld.lld, there will be link issue as below:
ld.lld: error: linker.lds:14: malformed number: :
>>> /DISCARD/ :
>>>
link script:
OUTPUT_FORMAT("elf64-x86-64","elf64-x86-64","elf64-x86-64")
OUTPUT_ARCH(i386:x86-64)
ENTRY(main);
SECTIONS
{
. = 0x10000;
.text : { *(.text) }
. = 0x8000000;
.data : { *(.data) }
.bss : { *(.bss) } =0x90909090
/DISCARD/ :
{
*(.eh_frame)
}
}
I have 2 ways to bypass the link issue:
1. remove the fill expression " =0x90909090";
2. add a section command before /DISCARD/, e.g.: ". = .;"
This issue only happens on newer version(>=9) of ld.lld, did not meet such
issue for old version.</pre>
