Bug ID: 26295
Summary: AArch64: CMASK and DMASK aren't valid DWARF registers
Assignee: unassigned at sourceware dot org
Reporter: alahay01 at gcc dot gnu.org
Target Milestone: ---
AArch64 PAC support added AARCH64_DWARF_PAUTH_DMASK and
These registers never made it in to a released version of "DWARF for the Arm
64-bit Architecture". They are not required, are not explicitly used by GDB and
can safely be removed.
Note that the cmask and dmask architecture registers are required.
AARCH64_DWARF_PAUTH_RA_STATE is also required.
*Remove defines for AARCH64_DWARF_PAUTH_DMASK and AARCH64_DWARF_PAUTH_CMASK.
*Remove usage in aarch64_dwarf_reg_to_regnum()
*Possibly correct usage of DWARF2_FRAME_REG_SAME_VALUE in
*Test with binaries compiled with PAC on a PAC enabled box.
Leaving this code in is probably harmless, but it should be tidied up.
