This is OK, but:
+/* AARCH64 extensions.
+ DW_OP_AARCH64_operation takes one mandatory unsigned LEB128 operand.
+ Bits[6:0] of this operand is the action code, all others bits are
initialized
+ to 0 except explicitly documented for one action. Please refer
AArch64 DWARF
+ ABI documentation for details. */
Is it possible to include a stable URL that points to the ABI document?
