<pre>Take the following use case as an example.
# RUN: llvm-mc -filetype=obj -triple=x86_64-pc-linux %s -o %t.o
# RUN: echo "SECTIONS { \
# RUN: .text : { *(.text) } \
# RUN: . = 0x200000; \
# RUN: .rodata : { *(.rodata) } \
# RUN: }" > %t.script
# RUN: ld.lld --no-rosegment -o %t -T %t.script %t.o
# RUN: llvm-readelf -S %t | FileCheck %s
.text
nop
.rodata
.word 0x41
.word 0x42
.word 0x43
.word 0x44
----------------------------------------------------------------------
LLD --always groups RO section with X sections.
This decision generates a huge binary for the above case.
lld: put rodata and text into one segment, Binary size: 2.1M
bfd: put rodata and text into separate segments, Binary size: 8.7k
BTW, --no-rosegment seems to be removed by bfd linker. (my version is ld-2.31.)</pre>
