If a "maintenance print reggroups" +command is issued, the default register set is dumped (which is fine). + +However, if a new group is added via an XML file, then that will +become the _only_ group. This behavior causes gdb.xml/tdesc-regs.exp +to fail. + +Fixes gdb.xml/tdesc-regs.exp on ARC. + +gdb/ChangeLog: +2020-01-15 Shahab Vahedi <shahab@synopsys.com> + + * arc-tdep.c (arc_add_reggroups): New function. + (arc_gdbarch_init): Call arc_add_reggroups. + +Will be a part of GDB 11: +https://sourceware.org/git?p=binutils-gdb.git;a=commit;h=d0cc52bdf2e6a586cac70000518c95619970619b +--- + gdb/arc-tdep.c | 18 ++++++++++++++++++ + 1 file changed, 18 insertions(+) + +--- a/gdb/arc-tdep.c ++++ b/gdb/arc-tdep.c +@@ -27,6 +27,7 @@ + #include "frame-base.h" + #include "frame-unwind.h" + #include "gdbcore.h" ++#include "reggroups.h" + #include "gdbcmd.h" + #include "objfiles.h" + #include "osabi.h" +@@ -1979,6 +1980,20 @@ + arc_frame_base_address + }; + ++/* Add all the expected register sets into GDBARCH. */ ++ ++static void ++arc_add_reggroups (struct gdbarch *gdbarch) ++{ ++ reggroup_add (gdbarch, general_reggroup); ++ reggroup_add (gdbarch, float_reggroup); ++ reggroup_add (gdbarch, system_reggroup); ++ reggroup_add (gdbarch, vector_reggroup); ++ reggroup_add (gdbarch, all_reggroup); ++ reggroup_add (gdbarch, save_reggroup); ++ reggroup_add (gdbarch, restore_reggroup); ++} ++ + static enum arc_isa + mach_type_to_arc_isa (const unsigned long mach) + { +@@ -2382,6 +2397,9 @@ + /* This doesn't include possible long-immediate value. */ + set_gdbarch_max_insn_length (gdbarch, 4); + ++ /* Add default register groups. */ ++ arc_add_reggroups (gdbarch); ++ + /* Frame unwinders and sniffers. */ + dwarf2_frame_set_init_reg (gdbarch, arc_dwarf2_frame_init_reg); + dwarf2_append_unwinders (gdbarch); |
