Bug ID: 30592
Summary: objcopy --set-section-flags: support "large" for
SHF_X86_64_LARGE
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: i at maskray dot me
Target Milestone: ---
Linkers may place SHF_X86_64_LARGE sections away from regular sections to
alleviate relocation overflow pressure [1]. It would be nice to have the
ability to add the SHF_X86_64_LARGE flag to sections in relocatable object
files, especially for prebuilt object files that the user cannot control.
I suggest that we allow objcopy --set-section-flags .data=alloc,large
to set SHF_X86_64_LARGE.
