Subject: [PATCH v2 0/6] ELF: Strip section header in ELF objects
Date: Sat, 3 Jul 2021 13:13:56 -0700 [thread overview]
Message-ID: <20210703201402.1136267-1-hjl.tools@gmail.com> (raw)
I have been carrying this set of patches for more than a year. It
takes forever to resolve Kaylee's paperwork with the FSF. Is there
a way to avoid such a long delay?
H.J.

Section header isn't mandatory on ELF executable nor shared library.
This patch adds a new linker option, -z nosectionheader, to omit ELF
section header, an new objcopy and strip option, --strip-sections, to
remove ELF section header.
H.J. Lu (4):
bfd: Improve nm and objdump without section header
binutils: Add a --strip-sections test
ld: Add tests for -z nosectionheader and --strip-sections
ld: Add -z nosectionheader test to bootstrap.exp
Kaylee Blake (2):
ELF: Strip section header in ELF objects
ld: Add a simple test for -z nosectionheader
