Add CFI unwind assembly directives for 64-bit ARM assembly
* cipher/asm-common-aarch64.h (CFI_STARTPROC, CFI_ENDPROC) (CFI_REMEMBER_STATE, CFI_RESTORE_STATE, CFI_ADJUST_CFA_OFFSET) (CFI_REL_OFFSET, CFI_DEF_CFA_REGISTER, CFI_REGISTER, CFI_RESTORE) (DW_REGNO_SP, DW_SLEB128_7BIT, DW_SLEB128_28BIT, CFI_CFA_ON_STACK) (CFI_REG_ON_STACK): New. * cipher/camellia-aarch64.S: Add CFI directives. * cipher/chacha20-aarch64.S: Add CFI directives. * cipher/cipher-gcm-armv8-aarch64-ce.S: Add CFI directives. * cipher/crc-armv8-aarch64-ce.S: Add CFI directives. * cipher/rijndael-aarch64.S: Add CFI directives. * cipher/rijndael-armv8-aarch64-ce.S: Add CFI directives. * cipher/sha1-armv8-aarch64-ce.S: Add CFI directives. * cipher/sha256-armv8-aarch64-ce.S: Add CFI directives. * cipher/twofish-aarch64.S: Add CFI directives. * mpi/aarch64/mpih-add1.S: Add CFI directives. * mpi/aarch64/mpih-mul1.S: Add CFI directives. * mpi/aarch64/mpih-mul2.S: Add CFI directives. * mpi/aarch64/mpih-mul3.S: Add CFI directives. * mpi/aarch64/mpih-sub1.S: Add CFI directives. * mpi/asm-common-aarch64.h: Include "../cipher/asm-common-aarch64.h". (ELF): Remove.
This commit adds CFI directives that add DWARF unwinding information for
debugger to backtrace when executing code from 64-bit ARM assembly files.
