aarch64: add STO_AARCH64_VARIANT_PCS and DT_AARCH64_VARIANT_PCS
|
|
|
|
STO_AARCH64_VARIANT_PCS is a non-visibility st_other flag for marking
|
|
symbols that reference functions that may follow a variant PCS with
|
|
different register usage convention from the base PCS.
|
|
|
|
DT_AARCH64_VARIANT_PCS is a dynamic tag that marks ELF modules that
|
|
have R_*_JUMP_SLOT relocations for symbols marked with
|
|
STO_AARCH64_VARIANT_PCS (i.e. have variant PCS calls via a PLT).
|
|
|
|
* elf/elf.h (STO_AARCH64_VARIANT_PCS): Define.
|
|
(DT_AARCH64_VARIANT_PCS): Define.
