Hi GDB, Binutils maintainer:

   OK on this proposal and install this patch to binutils-gdb master?

         * dwarf2.def (DW_OP_AARCH64_operation): Reserve the number 0xea.
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
+   to 0 except explicitly documented for one action.  Please refer
+   ABI documentation for details.  */

Is it possible to include a stable URL that points to the ABI document?


As this patch has got approve from GCC, is it OK to install into binutils-gdb master?

My understanding is "include/dwarf2.def" is shared between GDB and Binutils.

This patch and the described AArch64 DWARF proposal has got GDB ack from which, from my understanding, is a conditional approval given there is follow up GDB patches on multiplexing DW_CFA_GNU_window_save.

  This patch still need Binutils approval.
