gdb: LoongArch: Implement the iterate_over_regset_sections gdbarch method
When execute the following command on LoongArch:
make check-gdb TESTS="gdb.base/auxv.exp"
there exist the following unsupported and failed testcases:
UNSUPPORTED: gdb.base/auxv.exp: gcore
FAIL: gdb.base/auxv.exp: load core file for info auxv on native core dump
FAIL: gdb.base/auxv.exp: info auxv on native core dump
FAIL: gdb.base/auxv.exp: matching auxv data from live and core
UNSUPPORTED: gdb.base/auxv.exp: info auxv on gcore-created dump
UNSUPPORTED: gdb.base/auxv.exp: matching auxv data from live and gcore
we can see the following messages in gdb/testsuite/gdb.log:
gcore /home/loongson/build.git/gdb/testsuite/outputs/gdb.base/auxv/auxv.gcore
Target does not support core file generation.
(gdb) UNSUPPORTED: gdb.base/auxv.exp: gcore
In order to fix the above issues, implement the iterate_over_regset_sections
gdbarch method to iterate over core file register note sections on LoongArch.
By the way, with this patch, the failed testcases in gdb.base/corefile.exp
and gdb.base/gcore.exp can also be fixed.
