- Authentication-results: sourceware.org; auth=none
This patch series is to let GDB arm-linux-nat.c use ptrace commands
PTRACE_GETREGSET and PTRACE_SETREGSET if linux kernel supports.
Patch #1 and #2 are factoring out macros and variables into more
common files. Patch #3 checks whether PTRACE_GETREGSET is supported by
linux kernel. Patch #4 - #6 use PTRACE_{G,S}ETREGSET ptrace commands
to fetch and store general purpose registers, FP registers and VFP
registers.
The whole test series are tested on x86_64-linux and arm-linux (with
PTRACE_GETREGSET and without PTRACE_GETREGSET kernel support respectively).
After these patches, arm-linux-nat.c is similar to aarch64-linux-nat.c
in the aspect of fetching and storing registers. It paves the way for
multi-arch support in aarch64 gdb (aarch64 gdb can do native debugging
for arm program), which is the motivation of this patch series.
*** BLURB HERE ***
Yao Qi (6):
Move PTRACE_GETREGSET and PTRACE_SETREGSET to nat/linux-ptrace.h
Move have_ptrace_getregset to linux-nat.c
Check whether kernel supports PTRACE_GETREGSET
Fetch and store GP registers by PTRACE_{G,S}ETREGSET
Fetch and store FP registers by PTRACE_{G,S}ETREGSET
Fetch and store VFP registers by PTRACE_{G,S}ETREGSET
