+
+ Continuing work to convert the hppa targets to multiarch partial.
+
+ * hppa-tdep.c: (hppa_register_raw_size): New function replacing
+ the body of macro REGISTER_RAW_SIZE.
+ * hppa-hpux-tdep.c: Add new functions replacing macro bodies from
+ config/pa/tm-hppah.h. These functions will be used to initialize
+ the gdbarch structure.
+ (hppa_hpux_pc_in_sigtramp): New function.
+ (hppa_hpux_frame_saved_pc_in_sigtramp): New function.
+ (hppa_hpux_frame_base_before_sigtramp): New function.
+ (hppa_hpux_frame_find_saved_regs_in_sigtramp): New function.
+ Add gdbcore.h #include.
+ * config/pa/tm-hppa.h (REGISTER_RAW_SIZE): Change the definition
+ of this gdbarch-eligible macro to a call to the new associated
+ function.
+ * config/pa/tm-hppah.h (PC_IN_SIGTRAMP): Likewise.
+ (FRAME_SAVED_PC_IN_SIGTRAMP): Change the definition of this macro
+ into a call to the new associated function.
+ (FRAME_BASE_BEFORE_SIGTRAMP): Likewise.
+ (FRAME_FIND_SAVED_REGS_IN_SIGTRAMP): Likewise.
+ * Makefile.in (hppa-hpux-tdep.o): Add dependency on gdbcore.h.
+
