[PATCH 0/8] aarch64: Enable the RCpc3 (Release Consistency) extension

[Victor Do Nascimento]

Given the introduction of the third set of Release Consistency
processor consistent (RCpc) memory model-compliant instructions in
the form of FEAT_LRCPC3 as an optional extension from Armv8.2-a
onward, this patch series adds the relevant machinery to Binutils to
add support for the instructions it adds to the instruction set.

Victor Do Nascimento (8):
  aarch64: rcpc3: Add +rcpc3 architectural feature support flag
  aarch64: rcpc3: Create implicit load/store size calc function
  aarch64: rcpc3: Define address operand fields and inserter/extractors
  aarch64: rcpc3: New RCPC3_ADDR operand types
  aarch64: rcpc3: add support in general_constraint_met_p
  aarch64: rcpc3: Define RCPC3_INSN macro
  aarch64: rcpc3: Add integer load/store insns
  aarch64: rcpc3: Add FP load/store insns
