Bug ID: 28841
Summary: ld: Customize output section type
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: i at maskray dot me
Target Milestone: ---
On ELF platforms, an output section is SHT_PROGBITS by default.
https://sourceware.org/binutils/docs/ld/Output-Section-Type.html#Output-Section-Type
allows one to create a SHT_NOBITS type section.
It's useful to support an arbitrary type.
Then the user can create an output section with just data commands.
Currently there is some magic (bfd/elf.c special_sections_n recognizes `.note*`
as SHT_NOTE) which goes against the ELF spirit that attributes should be
identified as well known integers, not magic names.
% cat a.lds
SECTIONS
{
.noload (NOLOAD) : { BYTE(0) }
.info (INFO) : { BYTE(0) }
.note.package (SHT_NOTE) : { BYTE(0) } /* or .note.package (0x7) : {
BYTE(0) } */
.init_array (SHT_INIT_ARRAY) : { ... }
}
INSERT AFTER .note.gnu.build-id;
% as /dev/null -o a.o
% ld.bfd -T a.lds --build-id a.o -o a
It may be useful to customize sh_flags as well.
