[PATCH 0/6] ELF: Strip section header in ELF objects

[H.J. Lu]

Section header isn't mandatory on ELF executable nor shared library.
This patch set 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
