aarch64: Extract aarch64_indirect_branch_asm for sibcall codegen
Extract indirect branch assembly generation into a new function
aarch64_indirect_branch_asm, paralleling the existing
aarch64_indirect_call_asm function. Replace the open-coded versions in
the sibcall patterns (*sibcall_insn and *sibcall_value_insn) so there
is a common helper for indirect branches where things like SLS mitigation
need to be handled.
gcc/ChangeLog:
* config/aarch64/aarch64-protos.h (aarch64_indirect_branch_asm):
Declare.
* config/aarch64/aarch64.cc (aarch64_indirect_branch_asm): New
function to generate indirect branch with SLS barrier.
* config/aarch64/aarch64.md (*sibcall_insn): Use
aarch64_indirect_branch_asm.
(*sibcall_value_insn): Likewise.
