Luke Cheeseman 05f11dbf44 [AArch64] - Return address signing dwarf support ... Functions that have signed return addresses need additional dwarf support: - After signing the LR, and before authenticating it, the LR register is in a state the is unusable by a debugger or unwinder - To account for this a new directive, .cfi_negate_ra_state, is added - This directive says the signed state of the LR register has now changed, i.e. unsigned -> signed or signed -> unsigned - This directive has the same CFA code as the SPARC directive GNU_window_save (0x2d), adding a macro to account for multiply defined codes - This patch matches the gcc implementation of this support: https://patchwork.ozlabs.org/patch/800271/ Differential Revision: https://reviews.llvm.org/D50136 llvm-svn: 343089		2018-09-26 10:14:15 +00:00
