Subject: [PATCH 00/11] Displaced stepping on AArch64 GNU/Linux
Date: Wed, 07 Oct 2015 09:26:00 -0000 [thread overview]
Message-ID: <1444209985-15829-1-git-send-email-yao.qi@linaro.org> (raw)
This patch series adds displaced stepping on aarch64-linux. The
series refactors and reuses some aarch64 fast tracepoint instruction
relocation code in GDBserver, because both of fast tracepoint and
displaced stepping need to handle instruction relocation.
Patches #2 - #4 are about refactoring aarch64_relocate_instruction in
GDBserver in order to share it between GDB and GDBserver. A visitor
pattern is used, and aarch64_relocate_instruction decodes instructions
and visits different instructions by different methods of visitor.
See more details in patch #4. Patch #5 moves all visitor pattern stuff
and aarch64_relocate_instruction to arch/aarch64-insn.c, and patch #6
adds the displaced stepping support.
Patch #8 adds a new test case gdb.arch/disp-step-insn-reloc.exp which
uses insn-reloc.c too for displaced stepping. Patch #9 and #10 add
"aarch64_" prefix to function names, as a clean up of this series.
The whole series is regression tested on aarch64-linux, both native and
gdbserver.
