Bug ID: 49350
Summary: --set-section-flags without flags should clear most
flags
Product: tools
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: llvm-objcopy/strip
Assignee: unassignedb...@nondot.org
Reporter: jh7370.2...@my.bristol.ac.uk

GNU objcopy --set-section-flags allows the flag list to be empty, e.g. "objcopy
in.o out.o --set-section-flags .foo=" is a valid command. The impact is to
clear all non-preserved section flags (note that this is different to
--rename-section without any flags which preserves all flags except
SHF_OS_NONCONFORMING). llvm-objcopy currently treats an empty flag list as
invalid, producing an error "unrecognized section flag ''". We should change it
to be more consistent with GNU objcopy here.
