elf: Add GNU_PROPERTY_1_NEEDED
Add GNU_PROPERTY_1_NEEDED:
#define GNU_PROPERTY_1_NEEDED GNU_PROPERTY_UINT32_OR_LO
to indicate the needed properties by the object file.
Add GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS:
#define GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS (1U << 0)
to indicate that the object file requires canonical function pointers and
cannot be used with copy relocation.
binutils/
* readelf.c (decode_1_needed): New.
(print_gnu_property_note): Handle GNU_PROPERTY_1_NEEDED.
include/
* elf/common.h (GNU_PROPERTY_1_NEEDED): New.
(GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS): Likewise.
ld/
* testsuite/ld-elf/property-1_needed-1a.d: New file.
* testsuite/ld-elf/property-1_needed-1.s: Likewise.
