--- Comment #4 from Fangrui Song <i at maskray dot me> ---
This is a fairly useful object file size saving technique.
LLVM integrated assembler implemented this in 2015-05
(https://reviews.llvm.org/rG5960cee1f5299a5e7233c35fcb2518c08b761374)
"""
Building llvm+clang+lld with master and with this patch the results were:
master: 193,267,008 bytes
patch: 186,107,952 bytes
master non unique section names: 183,260,192 bytes
patch non unique section names: 183,118,632 bytes
So using non usique saves 10,006,816 bytes, and the patch saves 7,159,056 while
still using distinct names for the sections.
