This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds new definitions of PAC enabled PLTs and both BTI and PAC enabled PLTs. 2) It also defines the new dynamic tag DT_AARCH64_PAC_PLT for the PAC enabled PLTs. 3) This patch adds a new ld command line option: --pac-plt. In the presence of this option, the linker uses the PAC enabled PLTs and marks with DT_AARCH64_PAC_PLT. 4) In case both BTI and PAC are enabled the linker should pick PLTs enabled with both and also use dynamic tags for both. All these are made according to the new AArch64 ELF ABI https://developer.arm.com/docs/ihi0056/latest/elf-for-the-arm-64-bit-architecture-aarch64-abi-2018q4 *** bfd/ChangeLog *** 2019-03-13 Sudakshina Das <sudi.das@arm.com> * elfnn-aarch64.c (PLT_PAC_ENTRY_SIZE, PLT_PAC_SMALL_ENTRY_SIZE): New.
