* [Bug tdep/26295] New: AArch64: CMASK and DMASK aren't valid DWARF registers @ 2020-07-23 15:32 alahay01 at gcc dot gnu.org 2020-07-29 10:00 ` [Bug tdep/26295] " srinath.parvathaneni at arm dot com ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: alahay01 at gcc dot gnu.org @ 2020-07-23 15:32 UTC (permalink / raw) To: gdb-prs https://sourceware.org/bugzilla/show_bug.cgi?id=26295 Bug ID: 26295 Summary: AArch64: CMASK and DMASK aren't valid DWARF registers Product: gdb Version: unknown Status: NEW Severity: minor Priority: P2 Component: tdep Assignee: unassigned at sourceware dot org Reporter: alahay01 at gcc dot gnu.org Target Milestone: --- AArch64 PAC support added AARCH64_DWARF_PAUTH_DMASK and AARCH64_DWARF_PAUTH_CMASK. 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. To fix: *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 aarch64_dwarf2_frame_init_reg() *Test with binaries compiled with PAC on a PAC enabled box. Leaving this code in is probably harmless, but it should be tidied up. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
