<pre>lld 8.0 seems to misplace orphaned sections, according to GNU ld manual,
orphaned sections should be placed at the end of the output:
<a href="https://sourceware.org/binutils/docs/ld/Orphan-Sections.html">https://sourceware.org/binutils/docs/ld/Orphan-Sections.html</a>
lld 8.0 however seems to place some of them at the start, for example giving
the following (start) of a linker file:
SECTIONS
{
[...]
.text : AT(...) {
lld 8.0 produces the following section headers:
[ 0] NULL 0000000000000000 000000 000000 00
0 0 0
[ 1] .reloc PROGBITS ffff82d080000000 001000 000008 00 A
0 0 4
[ 2] .init.rodata.cst8 PROGBITS ffff82d080000008 001008 000008 08 AM
0 0 8
[ 3] .text PROGBITS ffff82d080200000 201000 1631ba 00 AX
0 0 4096
[...]
Placing the orphaned .reloc and .init.rodata.cst8 before the linker script
defined sections. Note that previos lld versions did not exhibit this
behaviour. The output of LLD_REPRODUCE can be found at:
