# Progress # * TCWG-162, Aarch64 non-stop debugging (or displaced stepping). [4/10] After testing, patches are posted upstream. * In order to review one c++ debugging patch, learn some C++ abi, vtable and VTT, etc. Understand gcc dump by -fdump-class-hierarchy. [3/10] * Fix GDB cxx build breakage caused by my patch. [1/10] * Ask the effect of -fstack-check=specific to AArch64 prologue. GDB needs update. [1/10] * Misc, email, meeting. [1/10]. # Plan # * TCWG-162, commit patches if no objections. * TCWG-387, use libopcodes to decode instructions in GDB. -- Yao

Fw: [Bug target/67877] New: Split stack needs to be support for AARCH64

by Pinski, Andrew

FYI. This is a parity feature with both PowerPC64 and x86_64. Needed to support GCCgo. Note full gold support is needed too. ---------- Forwarded message ---------- From: pinskia at gcc dot gnu.org <gcc-bugzilla(a)gcc.gnu.org> Date: Tue, Oct 6, 2015 at 3:30 PM Subject: [Bug target/67877] New: Split stack needs to be support for AARCH64 To: gcc-bugs(a)gcc.gnu.org https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67877 Bug ID: 67877 Summary: Split stack needs to be support for AARCH64 Product: gcc Version: 6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: pinskia at gcc dot gnu.org Target Milestone: --- Target: aarch64-linux-gnu* To support gccgo better split stack should be implemented.

# Progress # * TCWG-373, Aarch64 non-stop debugging (or displaced stepping). [2/10] Patches V1 are ready for upstream submission, but find opcodes has already interfaces to decode instructions, so decide to use opcodes for aarch64 GDB first. * TCWG-387, one patch exposing one opcode interface is pushed in. [4/10] Switch software single step code for aarch64 to using opcodes interface. Patch is pushed in. Rewriting prologue analyser to use opcode interface too. * TCWG-159, Kernel awareness in GDB. [1/10] Resume the work as Peter Griffin has cycles to do so. We are happy with the plan so far. * Review arm software breakpoint in GDBserver patches. [1/10] * Misc, [2/10] # Plan # * TCWG-387, TCWG-373 -- Yao
